Having grown up in the Finger Lakes region of upstate New York, Brow knew of the New York State College of Ceramics at Alfred, N.Y., through a family connection, and he knew he was headed toward engineering. But, it was not until he took “mud lab” from James Funk, an Alfred professor, that he found an intellectual home and a career. Brow says, “honestly, it was so much fun, I kind of fell into it then.” Similar chance events steered Brow into a career as a glass scientist. Helmut Schaeffer at the University of Erlangen (Germany) introduced him to glass science during a junior year study abroad. Thanks to an economic downturn and a tight job market in the early 1980s, Brow opted to go to graduate school and studied under William LaCourse at Alfred for his master’s degree. For his PhD, Brow headed south to Pennsylvania State University, where he was the first graduate student of Carlo Pantano. He credits LaCourse and Schaeffer for igniting a lifelong love of studying glass, “[They] turned me into a glass weenie, and I’ve been lucky enough to stay a glass weenie for the past 30 years!” A summertime stint at Sandia National Labs (Albuquerque, N.M.) turned into a full-time position after graduation, and Brow spent 13 years researching glass with other prominent scientists, including Ronald Loehman and Jeffrey Brinker. Brow’s lab also served as home base for visiting scientists, one of whom was Delbert Day. When Day was preparing to retire from the faculty at the University of Missouri, Rolla (now Missouri University of Science and Technology), he suggested Brow think about moving to academia, a move Brow made in 1997, where he remains on the MS&T faculty. Brow’s entrée into The American Ceramic Society was typical and understated—he gave a presentation at a Glass & Optical Materials Division meeting. From that auspicious beginning, he started organizing sessions at GOMD meetings, thinking, “Wouldn’t it be great to get this person and this person and this person from around the world together so I could learn from them?” Inevitably, his ACerS colleagues tapped him for the leadership stream of GOMD and now, the Society. Brow credits the Society with providing him an opportunity to grow professionally. “By taking on responsibility, I had a chance to develop collaborators and friends who, in the long run, really were important to my career,” he says. “I discovered it accidentally, but I think every young person that gets involved with the Society discovers it ‘accidentally.’ For me, it was finding people who were interested in the same things I was interested in, so I could learn from them.” So deep is Brow’s commitment to finding people from whom he can learn, that a primary goal of his presidential year is to establish a network of “technical interest groups,” or TIGs. He sees TIGs as a way to make it easier than ever to get involved in ACerS. “I would like to create within the Society the means for members to develop ideas, take advantage of emerging opportunities, or be able to cluster around a common interest.” American Ceramic Society Bulletin, Vol. 92, No. 1 | www.ceramics.org For example, according to Brow, a TIG might develop on the subject of biomaterials. Such a group would be able to engage people within the Society who might not otherwise find the organization or know of its resources. Brow says, “I can see these groups becoming fundamental to the way we do business and to the way we project ourselves to the rest of the world.” His second goal for the year perhaps harkens to his serendipitous discovery of ceramic engineering—finding ways for the Society to support ceramic engineering education. Brow observes, “There is good ceramic engineering being done at places like 3M and Boeing because the materials exist. The materials don’t change—maybe the way we educate engineers to deal with the materials changes—but the materials are still there.” He asks, “How do we identify who is working on ceramics out there, including in places like Boise or Amherst. How do we engage, nurture, and support these faculty and students?” After all, he notes, the industrial base necessarily casts its net for engineering talent to work on ceramic materials wider than the pool of ceramic engineers that graduate from Alfred and Rolla. Although the presidential year is very demanding, Brow probably had an easier time convincing his family of the merits of the role. His wife, Theresa McCarthy-Brow, is a Penn State ceramic engineer, too, and managed a program for the Air Force in New Mexico for making large pieces of glass for satellite deployment. They have two daughters, and the entire family enjoys following Cardinals baseball in their free time. Brow invites members to contact him at brow@mst.edu.n 3 news & trends NIST issues report on MGI workshop addressing data and standards The stated goal of the Materials Genome Initiative is “to double the speed at which we discover, develop and manufacture new materials.” The goals are clear, but how to tackle them is challenging. MGI will draw on the concerted efforts of academia, manufacturers, federal funding agencies, and national labs. Meanwhile, each of those constituencies must remain true to their missions, and there are often dependencies between them, for example, between academia and federal funding agencies. Also, as MGI’s White House point man, Cyrus Wadia, explained in and interview with the Bulletin in 2011, the idea is for MGI to evolve in a grass roots manner, not bureaucratically in a top-down way. Since it was announced in June 2011, the MGI has transitioned from a twinkle in the eye of the White House’s Office of Science and Technology Policy to a multi-agency initiative taking its first toddling steps. Indeed, with the first drops from the funding tap flowing from diverse fund- ing agencies, it looks like the concept is working. Even so, getting the materials science community’s collective arms around MGI is not so easy. NIST, as the nation’s data and standards experts, are naturally positioned to take a leadership role in defining the issues and guiding the development of a “materials innovation infrastructure.” NIST embraced that challenge/ opportunity and last May convened a workshop—“Building the Materials novel approach to modeling flow (www. simio.com)… Federal agencies to hold workshop on the design of the National Network for Manufacturing Innovation (www.manufacturing.gov)… Hindusthan National Glass and Industries has commissioned a 650-ton-per-day glass bottle plant at Naidupeta in Andhra Pradesh, India (www.www.hngil.com)… Robust vehicle sales are providing a boost to Pittsburgh Glass Works, which is adding 50 to 60 employees at its plant in Creighton, East Deer.

The workshop convened 125 stakeholders from academia, federal agencies, national labs, industry and professional societies. Most, although not all, participants came from United States organizations. In November, the agency released its summary report (http:// nvlpubs.nist.gov/nistpubs/ir/2012/NIST. IR.7898.pdf) summarizing the outcome of the exercise to evaluate the status of the Materials Innovation Infrastructure (MII) and identify gaps and opportunities. It also outlines the process the group used to attack the issue. Lead author of the report and NIST scientist Jim Warren explained in a phone interview that the MII is “about lowering the barrier to entry for manufacturers” to accelerate materials innovation. He says some disciplines are way ahead on developing a data infrastructure, for example, with regard to data sharing and quality, computer codes, metrics, etc. “We want to harvest the best practices and use them where it makes sense for materials science,” he says. Warren likens the coalescence of the MII to the birth and growth of the Internet “superhighway.” He says, “We are all willing to pay a small cost for access to the Internet, which makes our life better. The MII imagines something similar for materials data.” Another way the MII compares to an established infrastructure model is the US roads and highways system. Some roads are owned at the federal level, some at the state or local level, and yet other roads are private. Envision the emerging MII as having a similar mix of owners, access points, etc. At the workshop, the participants were charged with assessing data infrastructure in four areas: data representation and interoperability, data manage- ment, data quality, and data usability. To provide a framework for the discussion, participants considered the four areas in the context of two broad topics: length scale challenges and technical applications. Length scale challenges fall into two categories: challenges relating to the mathematics of the scale and crossing scale regimes, and challenges relating to the computing power needed to perform the calculations. For example, phase field methods are used to model microstructure development in the nanometer to micrometer range. However, microstructure development arguably can be modeled also at the crystal lattice scale with approaches such as density functional theory. Finding the mathematics that transitions between them is something like finding a clutch that can shift between first gear and fourth gear. Also, it does not take long to peg the computing power, according to Warren. Say, for example, you want to model one millimeter of a solidification interface. By modeling conditions every 10 angstroms normal to and along the interface, the computation very quickly generates terabytes of data. The workshop participants divided length scales into several regimes: macro, micro, nano and molecular lengths, and atomic lengths. Within each of these, challenges were pri- For solutions made from scratch, Just add Harper.

Experimental Tools NIST released its report from May’s MGI workshop, ”Building the Materials Innovation Infrastructure: Data and Standards.” oritized and categorized as short-term or long-term, based on whether their impacts could make a difference in less than five years or more than five years. For example, in the area of data representation and interoperability, participants identified the “definition of data or metadata for particular applications with standards for software to facilitate linkage,” as both a high priority and something achievable in the short term. The organizers of the workshop also recognized that new materials developed in the MGI construct would be developed with specific applications in mind. Thus, they considered four possible “technical application areas:” electrochemical storage, high-temperature alloys, catalysis, and lightweight structural materials. They selected these TAAs because, broadly speaking, they represent areas that are positioned well to adapt an MGI approach. Warren notes, however, that the four TAAs are only representative examples, and workshop organizers and participants acknowledge that there are many other applications that could have been considered instead. In both contexts, the key metric considered was the amount of time that could be saved if the data challenges were eliminated; cost issues were not addressed directly. Finally, the report calls out crosscutting challenges that impact anybody 6 Additive-manufactured ceramic heater unit playing role in Mars soil testing The work of the Mars Curiosity rover soil-sampling mission bubbled up to national attention recently when a NASA official touched off speculation when he mentioned that something “remarkable” and “for the history books” had been found. While it turned out that his phraseology might have been hyperbolic (although some proto-organic materials may have been found), the long-distance investigative work of the rover is a feat of remarkable engineering, made possible with several components either from the field of ceramics or well-known in the ceramics and glass community. For example, there is a piece of ceramic, formed by an additive manufacturing process—stereolithography—that is playing a significant role in the soil analysis. This piece is a custom alumina ceramic heater housing produced by Technology Assessment and Transfer Inc., a small defense and government contractor based in Annapolis, Md. The ceramic heater housing is an indispensable component of the rover’s SAM (Sample Analysis at Mars) instrument suite. SAM’s meat-andpotatoes work occurs when volatile materials from the Mar soil samples are fed into the suite’s six-column gas chromatograph, a quadrupole mass spectrometer, and a tunable laser spectrometer. However, before the GC, QMS and TLS can do their important work, the soil must be prepared carefully to release the volatile components—and that involves the ceramic heater body. It is a dimensionally small-but-central part (only 0.75 inches long with an external diameter of 0.5 inches″ and an internal diameter of 0.38 inches) of several ovens in SAM’s Sample Manipulation System, where solid phase materials are sampled by transporting finely sieved materials to one of 74 SMS quartz sample cups. The cups are inserted into the special oven and heated to release volatiles. The ovens also help clean the cups for reuse. While one might assume that fabricating the alumina housing was simple, it was not. NASA engineers designed it to support a network of channels with 52 heating elements allowing its oven capacity to reach 1,000°C. In an email to the Bulletin, Walter Zimbeck, manager of TA&T’s Ceramic Micro Devices Group, described some of the details and considerations about making the oven housings via the stereolithography route. He said that NASA selected the company after finding few rapid-prototyyping suppliers able to meet their specifications. “There were not any others,” says Zimbeck. “Goddard did have some prototypes made by plasma spraying alumina onto a mandrel and around pre-placed heating element wires, but apparently those prototypes failed during the first heating cycle (room temperature to ~1,000°C in several minutes). The ceramic cracked, and the wires broke. That’s a very challenging thermal shock event for any ceramic, so I was actually surprised that our fully dense high-purity alumina housings showed no signs of degradation after the first, nor after many, test cycles. The NASA pyrolysis oven team was elated because they were on the hook to provide the ovens and had no other solutions.” Zimbeck says the difficult part, and the reason why no conventional processes were viable, is the high aspect ratio of the holes that run the length of the cylinders. “The inner ring of holes have a 0.008 inch diameter and are about 0.75 inches long—an aspect www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 (Credit: NASA.) Goddard was not able to find anyone who would bid the design using conventional ceramic machining, injection molding, or extrusion plus machining,” he says. Once formed stereolithographically, the 30 units TA&T were heated for binder burnout and sintered, analogous to an injectionmolded ceramic. “The material we used for the ovens is Schematic of SAM (Sample Analysis at Mars) soil and a fine-grained, high-purity atmospheric analysis unit, part of Curiosity’s Mars alumina that sinters very well Science Laboratory. to near theoretical density,” ratio of almost 100!

So, when the Curiosity landed successfully, we were pretty excited—parts we made are on freakin’ Mars! Our excitement is amped up further now that we know the pyrolysis ovens are working and they may be essential to producing significant scientific findings,” Zimbeck says. Many of the analytical components in the SAM system (and in Earthbased labs working to troubleshoot and confirm Curiosity’s findings) were contributed by companies familiar to ceramists and other materials scientists and engineers. For example, equipment made by Netzsch is helping with thermal and gas analysis both on Mars and in labs on Earth that working to understand, duplicate, and verify the results from Curiosity. n CM Furnaces, long recognized as an industrial leader in performance-proven, high temperature fully continuous sintering furnaces for MIM, CIM and traditional press and sinter now OFFERS YOU A CHOICE, for maximum productivity and elimination of costly down time.

The IBAAS was established only earlier this year. The group’s website indicates that it was launched with a particular focus on supporting businesses and research in Asia. IBAAS notes the competitive and regulatory challenges to the field that underlined the society’s formation: “The bauxite, alumina, and aluminum industry is developing at a fairly good pace in the world and spectacular growth is visible in China, India, and Brazil. Several other countries like Vietnam, Saudi Arabia, Indonesia, and Guinea are proposing to invest huge amounts into development of the vast resources of bauxite. “While the downstream industry is facing the challenge of technology upgradation and high investment costs, the upstream industry is constantly under the threat of everchanging regulatory laws with respect to mining, social development, and technology, besides the need for a huge investment in infrastructure for the mining, refining, and smelting operations. “It is strongly felt that an organization is specifically needed to focus on these issues and work in the field of bauxite geology, mining, beneficiation, alumina refining and aluminum smelting technology particularly in Asian region. A group of leading scientists, engineers, managers and experts in this line have set up a registered society IBAAS to promote this industry in this part of the world.” IBAAS says it is initially giving special attention to India, China, Vietnam, Saudi Arabia, and UAE, 8 and hopes eventually to expand to the BRIC nations. The group’s first meeting, held with support from over 70 institutions and businesses (including many known well in the ceramics community, such as Ace Calderys, Almatis, Aluchem, Bharat Heavy Electrical Ltd., Central Glass and Ceramic Research Institute, IFGL Bioceramics Ltd., Jyoti Ceramics, Panalytical, Rio Tinto, Saint Gobain, SKG Refractories, and The Indian Ceramic Society) was cosponsored by the Jawaharlal Nehru Aluminium Research Development and Design Centre, and was held December 3-5. Besides technical papers in scientific sessions, the conference had special sessions on “processing innovations in aluminum ceramics” and “new and emerging application of alumina ceramics.” The meeting seems to have gotten quite a bit of publicity in India, and the Times of India reported that the symposium also served as a platform for researchers and industry “to work out plans for metallurgical bauxite and special alumina products.” Several developments announced at the meeting are worth noting. The first comes from the Central Glass and Ceramic Research Institute (CGCRI), which says it has developed a process to convert extremely inferior grade bauxite into refractory grade bauxite. CGCRI says its process removes impurities, such as calcium oxide, titanium oxide, and iron oxide from bauxite. The institute says it uses certain natural materials that selectively absorb these impurities and effectively increases the melting point to 1,600°C. In an interview with the Times, CGCRI’s Anup Ghosh says, “We have converted the low-melting-point phase bauxite into high-temperature phase. This can be used even in steel melting process.” Institute leaders report that they have received industrial support to scale up the technology to at least oneton capacity. Separately, CGCRI also announced that it has succeeded in using “extreme- (Credit: IBAAS.) news & trends ly inferior grade” bauxite to make extremely hard ceramic tiles. “The hardness has been brought by blending other industrial wastes like fly ash and iron ore tailings to make the new ceramic. It can be used as a lining in hoppers and chutes used in steel plants and coal washeries. It helps prevent corrosion and abrasion,” Swapan Kumar Das, chief scientist at refractories division in CGCRI, explains to the newspaper. The institute has a history of working with alumina, and its uses in membranes, tubing, and bioceramics. Another meeting development drew considerable interest: A Canadian company, Orbite Aluminae Inc., announced that it has pioneered an unconventional source of alumina. Again according to a story in the Times, OAI says that instead of using bauxite, it can efficiently use aluminous clay or clay rich in alumina and silica to produce extremely pure alumina. The company says its methods also are environmentally friendly. OAI says it succeeded for the first time in achieving a one-ton-per-day production rate of purified alumina in early 2011. That was apparently on a prototype-production basis, but the company says that it will launch a oneton-per-day plant in January 2013 in Quebec. OAI says this alumina initially will be used in LED production, not aluminum. Besides bauxite, OAI says it can process red mud and fly ash, and says that the method also generates rare earth elements. The company says its vision is to build high-purity alumina plants across North America. It hopes to start producing smelter-grade alumina by 2015 and eventually to have ten plants in Quebec alone.

In December, Milliron’s efforts were rewarded with a $3 million ARPA-E grant to further efforts to improve the performance and lower production costs for materials that will yield commercial electrochromic windows. But Milliron’s group, part of LBL’s Molecular Foundry, along with the lab’s Environmental Energy Technologies Division, believes the current line of commercial smart windows is not agile enough and still too far from affordable for most applications. ARPA-E would like to see smart windows that can separate the filtering of visible light from the filtering of near-infrared radiation (NIR), along with a technology that efficiently uses current glassmaking techniques. According to a press release, the researchers believe they have candidate nanocrystal thin films that can individually block the NIR and visible light components, and additionally have an inexpensive approach for applying the film that is similar to spray-painting a car. Ultimately, they want to deliver a low-cost window that can be toggled among various settings, such as fully opaque, transparent for visible light but not NIR, transparent for NIR but not visible light, or fully transparent. Berkeley Lab has already spun off a company, Heliotrope Technologies, to work on commercial development of the electrochromic applications. For more about Milliron’s research into the above-mentioned materials, see, for example, “Tunable Infrared Absorption and Visible Transparency of Colloidal Aluminum-Doped Zinc Ultrathin rust films trap sunlight for splitting water Water molecules are a great place to store hydrogen. Now that the “hydrogen economy” is getting some traction, the question is how to get the hydrogen “out of storage.” One way to unlock the hydrogen is photoelectrolysis—using the sunlight to split the water. The photoelectrolysis process involves capturing sunlight, converting it to current, using the current to electrically split the water molecule, and harvest out the hydrogen. Some semiconducting materials are able to convert sunlight into charge carriers, i.e., current. Because we expect to need a lot of hydrogen, we are going to need a lot of semiconducting material that is stable in aqueous environments, nontoxic, abundant, inexpensive, and able to absorb visible light. Rust, in thinfilm form, meets those requirements. However, α-Fe2O3 (hematite) has poor transport properties, and the “photogenerated” charge carriers generally recombine before they can be used to do any work. Researchers at the Technion-Israel Institute of Technology may have found a way around the recombination problem in photoelectrolysis anodes, or photoanodes, according to a new paper published in Nature Materials. In a press release, lead researcher Avner Rothschild, associate professor in the at Technion’s Department of Materials Science and Engineering, says, “Our light-trapping scheme overcomes this trade off [between light absorption and charge carrier recombination], enabling efficient absorption in ultrathin films wherein the photogenerated charge carriers are collected efficiently.” The efficiency of the 20–30-nanometer-thick α-Fe2O3 films has two sources. First, according to the paper’s abstract, American Ceramic Society Bulletin, Vol. 92, No. 1 | www.ceramics.org the films are designed as optical cavities that trap light and efficiently collect the charge carriers. The penetration depth of visible light in iron oxide is about a micrometer, but the photogenerated charge carriers are collected only in a 2–20-nanometer range. So, the key is to push, or trap, the light into a 20-nanometer range that is located near the place where the charge is needed, i.e., a surface. Rothschild explains, “The light is trapped in quarter-wave or even deeper sub-wavelength films on mirror like back reflector substrates. Interference between forward- and backwardpropagating waves enhances the light absorption close to the surface wherein the photogenerated charge carriers are collected before recombination takes place. The escaped (back reflected) photons are retrapped by a second ultrathin-film photoanode in front of the first photoanode, thereby leading to efficient photon harvesting using 20–30-nanometer-thick α-Fe2O3 films.” In this way, the light intensity is amplified near the surface of the photoanode, where it oxidizes the water before recombining. The second aspect to maximizing efficiency involves smart design of the photoanode geometry. The abstract reports that V-shaped cells, for example, are especially efficient at harvesting light in these ultrathin films. Rothschild says the new technology could lead to cost-effective, integrated solar cells that combine the ultrathin iron oxide photoelectrodes with standard silicon-based solar cells and thereby produce electricity and hydrogen. He also says the light-trapping research could reduce the need for rare elements in so-called second generation photovoltaic cells, such as tellurium in CdTe cells or indium in Cu-In-Ga-Se cells. The paper is “Resonant light trapping in ultrathin films for water splitting,” H. Dotan, O. Kfir, E. Sharlin, O. Blank, M. Gross, I. Dumchin, G. Ankonina, and A. Rothschild, Nature Materials (doi: 10.1038/nmat3477). n 15 advances in nanomaterials Perovskite oxides: Group shows technique for engineering ‘perfect’ heterointerfaces New ultrathin VO2 film device perfectly, reproducibly absorbs infrared light A new paper by a research team at the Harvard University School of Engineering and Applied Sciences reports on a new device that is an exceptionally efficient, perfect absorber of infrared light. The team expects it to be useful for a range of applications, such as temperature measurement, spectroscopy, tunable filters, thermal emitters, radiation detectors, energy harvesting, and high-sensitivity thermal cameras. In a press release, associate professor and coauthor Shriram Ramanathan says that near the VO2 insulator-tometal polymorphic phase transition the film has a “very complex and rich microstructure in terms of its electronic properties, and it has very unusual optical properties.” With the phase transi(Credit: Choi et al.; Adv. Mat. Wiley.) Oak Ridge National Lab researcher Ho Nyung Lee has studied complexoxide thin films for more than a decade, and, during this time, he has been interested in exploiting the potential properties of functional complex-oxide perovskites thin films. In particular, Lee leads a research team that has been striving to develop techniques to create perfect or nearly perfect thin films and superlattices by precisely controlling surfaces and interfaces. In a newly published paper, Lee and his fellow researchers report they have been able to engineer a chemically stable and atomically sharp lanthanum aluminate monolayer (i.e., a perfect or nearly perfect interface) between LaAlO3 and strontium titanate heterostructures. The core of the group’s findings is that a single unit-cell layer of LaAlO3 grown on a SrTiO3 substrate serves as a buffer and is sufficient to dramatically improve the interface quality. In an ORNL press release, Lee says, “This means that we can now create new properties by precisely conditioning the boundary in the process of stacking different oxides on top of each other.” The group’s general approach is to use pulsed laser deposition (PLD) to grow the LaAlO3 on the SrTiO3 substrates at relatively low oxygen pressures. The breakthrough came when Lee and the others began to systematically examine how varying the oxygen pressure would affect the thin-film structure. After looking at a wide range of pressures, their results showed an unexpected phenomenon: Relatively high oxygen pressure can initially produce a “shielding layer” of LaAlO3, and, when this was followed by PLD growth at a lower pressure, the end result was a highly ordered, essentially defect-free interface. One apparent advantage of this development, the group reports, is this is not an isolated effect, and the atomic layering technique appears to be applicable to perovskite oxides in general. The group’s work is published in Advanced Materials in a paper titled “Atomic Layer Engineering of Perovskite Oxides for Chemically Sharp Heterointerfaces” (doi:10.1002/ adma.201202691). n Schematic of the structure of a typical lanthanum aluminate-strontium titanate interface, left, and the abrupt, sharp interface obtained through an atomic layer engineering method developed at ORNL. 16 tion, the optical properties of the film change from transparent to reflective. The substrate, sapphire, it turns out, is opaque to certain infrared wavelengths and reflects the light back. Thus, the VO2–sapphire interface is, itself, an optical trap. Ramanathan tells the Bulletin that the optical effect in VO2 films is very sensitive to the quality or purity of the film, and, therefore, to the physical vapor deposition processing parameters. “There are many compounds that are possible, and we want to make phasepure samples with as pure a composition as possible,” he says. “It is only recently that we have been able to synthesize exceptionally high-quality films. Stabilizing the phase is a very hard problem.” The films can be epitaxial, depending on the substrate. The group has grown films on several substrates, including sapphire and titania. The tuning range for a device such as this is approximately 80 percent to 0.25 percent reflectivity. Ramanathan explains that the transition threshold of the film can be controlled by electric fields, doping with charge carriers, or adjusting the lattice constant with dopants such as W, Cr and Nb, or lattice strain during film deposition. In addition, the phase transition is “very reproducible through millions of cycles, with the right composition,” says Ramanathan. The dielectric constant of VO2 also undergoes rapid change with the VO2 phase transition, so his group has been studying the material for high-speed switches and other ultrahigh-speed electronic applications. This new ability to control the optical characteristics opens up new possibilities. “We are starting to think about opto-electronic platforms. What type of oxide electronic devices can we make?” The paper is “Ultra-thin Perfect Absorber Employing a Tunable Phase Change Material,” M.A. Kats, et al., Appl. Phys.

During the past 50 years, optical fibers have moved from novelty to ubiquity. Although the public pays little attention to the composition of these fibers, really, why should they? After all, most of the optical fiber in use today is of the “plain vanilla” variety composed primarily of silica glass. These workhorse fibers now, of course, are the backbone of global telecommunications that deliver high-speed data and entertainment across continents and into homes and offices. Basic optical fibers also have made possible remarkable advances in surgery, structural-integrity systems, and manufacturing, including advances in fiber-based lasers. But, although, ordinary silica optical fibers will continue to play a big role in the foreseeable future, a number of scientists and engineers believe that totally new types of uses for optical fibers could be in reach if the “right” types of fibers were available. What are some of the suggested new uses? Some of the examples mentioned among glass engineers include fibers that react with an electrical signal when exposed to external light, temperature changes, or ultrasonic signals; fibers that monitor their own performance; and even fibers that may play a role in various types of “cloaking,” à la metamaterials. Some have suggested that revolutionary types of fabrics that incorporate electronic and optoelectronic fibers are easily foreseen. Clearly, researchers have something in mind beyond ordinary optical fibers, and one of the ideas emerging in recent years is the concept of multimaterial fibers, i.e., using the introduction of new materials into the fiber composition to yield new structures, functionalities, and applications. (See, for example, “High-alumina optical fibers get around Brillouin scattering limitations,” in the October–November 2012 Bulletin, Vol. 98 [1] pp 16–17.) 17 cover story (Credit: Agresta; ANL.) bulletin X-ray nanodiffraction instruments, such as this one at the Advanced Photon Source of Argonne National Laboratory, allow researchers to study the structure and functional properties of thin-film materials, including ceramics and the integrated circuit shown here, with spatial resolutions of tens to hundreds of nanometers. In situ X-ray characterization of piezoelectric ceramic thin films By Paul G. Evans and Rebecca J. Sichel-Tissot Advances in X-ray scattering characterization technology now allow piezoelectric thin-film materials to be studied in new and promising regimes of thinner layers, higher electric fields, shorter times, and greater crystallographic complexity. 18 T here has been rapid development in the precision with which ferroelectric material can be grown epitaxially on single-crystal substrates and in the range of physical phenomena exhibited by these materials. These developments have been chronicled regularly in the Bulletin.1,2 Ferroelectric thin-film materials belong to the broad category of electronic ceramics, and they find applications in electronic and electromechanical devices ranging from tunable radio-frequency capacitors to ultrasound transducers. The importance of these materials has motivated a new generation of materials synthesis processes, leading to the creation of thin films and superlattices with impressive control over the composition, symmetry, and resulting functionality. In turn, improved processing has led to smaller devices, with sizes far less than 1 micrometer, faster operating frequencies, and improved performance and new capabilities for devices. Important work continues to build on these advances to create materials that are lead-free and that incorporate other fundamental sources of new functionality, including magnetic order. www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 X-ray diffraction X-ray diffractometry techniques provide direct insight into the piezoelectricity of ceramics and epitaxial oxides. Several experimental approaches do this by taking advantage of timeresolved scattering techniques.6–9 For example, X-ray scattering experiments take advantage of the highly bril- (Credit: Chen, et al.; American Institute of Physics. Reprinted with permission.) The polarization of ferroelectric materials can be changed by changing the applied field. (See sidebar “Piezoelectricity, crystal structure, and symmetry.”) Polarization switching has profound effects on the piezoelectric distortion because the piezoelectric coefficients are effectively reoriented when the polarization is changed. Piezoelectricity is thus an excellent marker for the interplay of mechanical and electronic phenomena responsible for polarization switching. The thinness, faster operating timescales, and novel structural degrees of freedom available in epitaxial ferroelectric thin films pose difficult challenges for characterization using conventional experimental methods. Researchers have developed a series of powerful— now standard—characterization techniques based on measuring the displacement of the surface of the thin film using piezoelectric force microscopy or interferometry.3 Alternatively, the stress imparted by the piezoelectric material can be quantified using the curvature of the substrate or a cantilever.4 Another approach is to use focused ion-beam milling or selective etching to create a bridge structure or cantilever into the film by removing a section of the underlying substrate and to observe the distortion of the shape of this structure.5 These approaches have proved to be phenomenally successful, but face important limits, particularly regarding time resolution and the precision with which the relationship between atomicscale effects and the overall electromechanical distortion of the sample can be determined. Understanding the atomic origins of piezoelectricity, particularly at nanosecond time scales, has proved challenging, but new techniques based on X-ray scattering address this void. liant beams of X-rays with tunable photon energy that are available at synchrotron light sources (see sidebar “Synchrotron Radiation,” p. 23).

The strain and diffrac- Piezoelectricity, crystal structure, and symmetry—The piezoelectric coefficients Piezoelectricity results from the polarization of crystals lacking inversion symmetry. In these materials, an applied stress leads to a change in the electrical polarization, and, conversely, applied electric fields lead to a change in the lattice constants, referred to as the piezoelectric strain. In the limit of small strains, fields, and stresses, the piezoelectric strain is proportional to the applied electric field, and the strain tensor and electric field are related by εjk = dijk∙Ei, where is the strain tensor, d is the piezoelectric coefficient, and E is the applied electric field vector.20 Note that the piezoelectric tensor can lead to strains and shears along directions that are orthogonal to the applied field. The units of d, more properly referred to as the converse piezoelectric coefficient, are distance divided by potential difference, often given in picometers per volt. The three-index notation for the piezoelectric coefficient can be reduced to a two-index notation, dij, where the index i refers to the electric field direction in the conventional manner where 1, 2, and 3 refer to the x, y, and z directions, respectively. The second index j refers to elements of the strain tensor using Voigt notation.20 The tensor of converse piezoelectric coefficients dij relates the piezoelectric strain εj to the electric field Ei: [ ][ d11 d12 d13 d14 d15 d16 ε1 ε6 ε5 ε6 ε2 ε4 = d21 d22 d23 d24 d25 d26 d31 d32 d33 d34 d35 d36 ε5 ε4 ε3 ][ ] E1 E2 E3 The symmetry of thin films and ceramics is such a strong effect that a second, engineering notation, is widely used in describing the piezoelectric coefficients. The notation and units are identical to the ones described above, which can lead to some confusion about which definition is in use. In the engineering notation, piezoelectric coefficients are defined so that the z direction, corresponding to subscript 3, is always in the direction of the applied electric field. Thus, the expansion along the field direction is determined by the piezoelectric coefficient d33 in the engineering notation. The symmetry of the piezoelectric tensor also is different between the two definitions. In the crystallographic definition, the piezoelectric tensor has the symmetry of the crystallographic unit cell. In the engineering definition, the tensor has the same symmetry as the overall shape of the piezoelectric thin film or ceramic solid, which is quite different from the crystallographic symmetry. The multiferroic complex oxide bismuth ferrite BiFeO3 is an excellent example of the difference between the crystallographic and engineering definitions of piezoelectricity. Although BiFeO3 has rhombohedral symmetry in bulk crystals, a pseudocubic notation for the BiFeO3 piezoelectric tensor and X-ray reflections are often used to emphasize the epitaxial relationship between the BiFeO3 thin film and its cubic substrate. The rhombohedral symmetry of BiFeO3 is not apparent from this notation, which has the side effect of complicating the expression for the piezoelectric tensor. Projecting the piezoelectric tensor onto the [100], [010], and [001] directions of a tetragonal material forces most of the terms to be zero and makes many of the remaining coefficients identical.20 n American Ceramic Society Bulletin, Vol. 92, No. 1 | www.ceramics.org 19 In situ X-ray characterization of piezoelectric ceramic thin films Measuring lattice constants of piezoelectric thin films Epitaxial thin-film capacitors are an excellent system for testing new ways to 20 variation of the lattice constant during the pulse. Systematic measurements of the piezoelectric properties of thin-film capacitors can be made by either applying voltage pulses of various magnitudes or by sweeping the voltage and recording the diffraction pattern as a function of time. The latter approach is shown in Figures 2(a) and (b) and shows the distortion resulting from positive and negative pulses applied to the bottom electrode of a Pb(Zr,Ti)O3 (PZT) thin-film capacitor.12 The measurements required a series of thousands of electric-field pulses to allow acquisition of the diffraction pattern over the full range of relevant angles. In this case, positive and negative pulses produce piezoelectric expansion because the first few pulses are enough to switch the sign of the polarization of the PZT capacitor. Combining the strains measured from the shift of the diffraction pattern with the time dependence of the voltage leads to the plots of strain as a function of voltage shown in Figure 2(c). The slopes of these lines give piezoelectric coefficients that are consistent with previous measurements in the same material.12 Alternating the sign of applied voltage pulses switches the capacitor between two polarization states in each repetition of the pulse sequence. The diffraction patterns and strain observed in this case are shown in Figures 3(a) and (b). As was the case in Figure 2, large pulses of either sign lead to large piezoelectric expansions. When the voltages switch signs, however, the Figure 3. (a) Piezoelectricity-induced angular shift of the 002 Bragg X-ray reflection of a Pb(Zr,Ti)O3 thin film in a bipolar applied electric field.

For example, Figure 1 shows the structural changes induced in an epitaxial thin film of BiFeO3 by an electric field pulse lasting 12 nanoseconds.11 The piezoelectric expansion during the electricfield pulse—a strain of approximately 0.5 percent—shifts the diffraction peak to a smaller wavevector, qz. For this measurement, the electric fields were Figure 2.

Reciprocal space the equipment generating the voltage is spanned by wavevectors so that the pulses. The characteristic rise-and-fall Bragg reflections occur at wavevectors with magnitude q = 2π/d. The intensity times of the shift in the diffraction peak shown in Figure 1 are 1.4 nanoseconds of X-ray reflections depends on the and correspond to the charging time direction of the polarization, an effect that can be combined with nanofocused constant of the capacitor. In addition, the shift of the diffraction peak X-ray beams to produce maps of the 10 provides a quantitative measure of the direction of the remnant polarization. Because X-ray diffractometry allows for precise measurement of lattice parameters, the piezoelectric coefficients can be determined in situ, that is, while the sample is subject to either constant or varying electric fields. Consequently, in situ X-ray diffractometry provides a means to begin understanding the fundamental source of piezoelectric phenomena. In Figures 2 and 3, the direction along which the X-ray experiments probed the piezoelectric strain was parallel to the direction of the applied electric field. Thus, the piezoelectric coefficients measured in this case correspond to the d33 component of the piezoelectric tensor. In the thin-film case, only E3 is nonzero, and the piezoelectric coefficients that determine the tensile or compressive strain are d31, d32, and d33. Shear strains are determined by coefficients, d34, d35, and d36. Timeresolved microdiffractometry probes the out-of-plane and the in-plane piezoelectric response, measuring the strains ε1, ε2, and ε3 from changes to the in-plane lattice constants and the out-of-plane c-axis lattice constants, respectively. The full piezoelectric tensor is particularly important for BiFeO3 because the bulk rhombohedral unit cell is distorted during epitaxial growth, leading to a complex thin-film microstructure.13 Instead of a single intense peak, the {103} reflections of BiFeO3 are split because the film has regions with the four possible orientations of its rhombohedral distortion relative to the cubic substrate, as well as varying degrees of plastic relaxation and tilt. Applying a voltage in this case results in a piezoelectric response that depends on the local structure of the thin film. Figure 4 shows the piezoelectric response by plotting positions in reciprocal space of the BiFeO3 pseudocubic {103} reflections for several electric fields.14 The arrows in Figure 4 indicate the change in reflection positions as E increases from 0 to 250 kilovolts per centimeter.

Wisconsin-Madison.) Piezoelectricity in thin films with complex microstructures comes from two closely related effects. The first is the piezoelectric expansion of the lattice. A second, more subtle effect, is the rotation of the {103} planes as the c lattice constant increases, which rotates the peak position around the origin in reciprocal space.

In epitaxial ferroelectrics, polarization switching occurs by a process in which domains of the polarization favored by the field nucleate and grow across the film. This process can be imaged stroboscopically by using the large piezoelectric expansion that occurs when the polarization switches as a marker Figure 6.

The precision with which lattice parameters can be measured in X-ray studies allows piezoelectric coefficients to be extracted quantitatively for thin-film materials, in the conventional case where the films expands normal to the surface and when adjacent areas cooperatively vary their in-plane structures. In more complex systems, in situ probes allow the properties of piezoelectrics to be studied at high electric fields, very short pulse times, and in systems with unusual domain patterns. Further applications of this approach will allow researchers to better understand the relationship between piezoelectric properties and crystallographic symmetry, for example, in testing theoretical predictions of the role of distortions of oxygen octahedra in superlattice materials.19 Advances in X-ray technology will allow these studies to extend to shorter picosecondscale times, and with improvements in X-ray detectors, to probe less-wellordered systems including polymers and other organic piezoelectrics.

Ferroelectr., 101, 174 (2009). 12 Synchrotron radiation Third-generation X-ray sources from synchrotron light sources, such as the Advanced Photon Source at Argonne National Laboratory (Argonne, Ill.), generate X-rays with very high intensity and small angular divergence, termed "brilliance." This brilliance, in turn, allows X-rays to focus to very small spot sizes, on the order of 100 nm or smaller. This spatial resolution is comparable to scanning probe microscopy and makes the study of the functional properties of highly heterogeneous materials possible. X-ray wavelengths are selected to match the needs of the experiment. Wavelengths of ~1 Å, which are required for diffractometry experiments, easily penetrate the top electrodes of device structures, such as capacitors, which allows in situ studies to be performed in applied electric fields. Even with the angular convergence introduced by focusing, synchrotron X-ray diffractometry experiments have sufficient precision to observe piezoelectric strains on the order of 10–5. In these studies of piezoelectricity, the thin-film capacitor is positioned at the focus of the X-ray beam and the diffractometry experiment is conducted in an electric field provided by a probe tip contacting the top electrode.

An indenter applies force P at a distance d away from the edge until a flake pops off. The photo shows chips in glass. E Edge chip testing of ceramics By George D. Quinn Prehistoric engineers chipped stone edges to make spear tips, but modern engineers need to avoid edge chipping. New test methods provide quantifiable measurement of edge chipping of ceramics. 24 dge chipping is a common mode of fracture for ceramics, glasses, and lithic materials. Edge chipping is a useful technique for shaping lithic (“of the nature of or relating to stone,” New Oxford American Dictionary) materials into cutting tools and, indeed, was a key manufacturing innovation for prehistoric cultures making spear tips. However, it is a nuisance and often a problem for technical ceramics and glasses. For instance, one report mentions an incident wherein 49 silicon nitride cam roller follower parts fell from a measurement bench and 40—more than 80 percent—sustained chip damage.1 McCormick and Almond2–4 started quantitatively assessing edge-chipping resistance of technical ceramics in 1986 at the National Physical Laboratory outside London. They initially evaluated carbide cutting-tool materials, but also looked at polycrystalline alumina, sapphire, zirconia, ceramics, and crown glass for comparison and to investigate the general applicability of their method. Other groups adopted their methodology and applied it to other materials. The edge-chipping test involves applying an increasing force near the edge of a specimen until a chip (or flake) forms, as illustrated in Figure 1. Usually, specimens are rectangular blocks with 90° edges. However, the test provides a means for designers to experiment with various edge geometries during the design process. For example, McCormick,3 for example, experimented with edges other than 90°. Testing can be done with a dedicated edge-chipping machine that www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 Figure 3. Edge chip data trend. Ceramic engine parts A diesel engine manufacturer’s materials selection process identified zirconia as superior to traditional tool-steel for fuel injector plungers, which might seize in short times if there is water in the fuel. The manufacturer had an option to make fuel injector plungers with zirconias stabilized with various additives (Figure 4(a)). Prototype testing of zirconia parts showed that (Credit: G.D. Quinn.) Figure 4. Comparative results for two zirconias for a diesel engine fuel injector pin. The darker ceria-doped TZP zirconia has superior edge chip resistance. American Ceramic Society Bulletin, Vol. 92, No. 1 | www.ceramics.org quickly at low loads. Other indenters, such as the Rockwell C indenter, are more blunt, and much greater force is needed to initiate starter cracks that eventually will grow to form the chip. There are about a dozen teams around the world now working on this methodology for various applications, such as quality control, material rankings, materials development, and engineering design evaluations. Some of these are described below. Force (N) McCormick and Almond arrived at three important conclusions. • Flake geometries are remarkably similar and appeared to be independent of the distance, force, or material. The larger the distance from the edge and flaking load, the larger the chip, but the shape is invariant. • The force versus distance trends are usually linear. • The chipping resistance increases with increased KIc or increased GIc, which are fundamental material properties that characterize a material’s resistance to fracture. Morrell and Gant7,8 continued the NPL work. Subsequent work by various groups (e.g., Gogotsi et al.9–11) has shown that sometimes the force–distance data follow a linear trend and sometimes they do not. The best trend to fit the data depends upon the material and the type of indenter. Some sharp indenters cause starter cracks to form (Pins courtesy of Cummins Engine Co.) uses a microscope to precisely locate an indentation site, such as is shown in Figure 2. Alternatively, a conventional universal testing machine can be used. However, precise alignment of the indentation site and posttest measurement of the edge distance is more difficult. McCormick and Almond developed the test with rounded-tip Rockwell C-type indenters (120° conical shape with a tip radius of 0.2 mm). However, subsequent studies also use Vickers, Knoop, and sharp conical 120° indenters. The greater the distance from the edge, the more force it takes to make a chip. Thus, data usually are plotted as the load versus the distance, as shown in Figure 3. Often the data follow a linear trend, but, sometimes, a powerlaw trend is a better fit, depending on the material and the type of indenter. The slope of the line resulting from a linear fit constitutes the “edge toughness parameter” and is designated Te or M. Steep slopes, i.e., large values of Te, indicate a material is resistant to edge chipping—large loads are needed to induce chip fracture even at small distances from the edge. Conversely, small Te values indicate that the material chips easily. Other important mechanical properties, such as fracture toughness, KIc, or the critical strain energy release rate, GIc,2,4–6 can be related to Te, also. The plot also identifies the “edge strength” parameter, SE(0.5), which is defined as the force it takes to make a chip at a distance of 0.5 millimeters from the edge.

The arrowheads shown in Figure 6 are obsidian, a volcanic glass, and were formed by controlled chipping, or “knapping.” Obviously, obsidian occurs only in locales near volcanoes, but the samples show clearly the flakedoff regions that shape the arrowheads. More commonly, ancient arrows, spears, and knives were knapped from local lithic materials. The stone was shaped by the removal of a single flake at a time. The archeological literature mentions that heat treatment below 500°C improves the workability of lithic materials, but, heretofore, this has not been verified quantitatively. To address the question, J. Quinn, Bradt, and Hatch applied the edge-chipping test to yellow Bald Eagle Jasper found in Pennsylvania.14 This is a well-studied amber-colored lithic used to make cutting tools in prehistoric times. The authors cut rectangular specimens from a large nodule. One specimen was heat-treated at 350°C for 12 hours. 26 The stone changed color from amber to dark red, similar to that in fragments found at archeological sites. There were significant microstructural and phase changes, which are described in Ref. 14. The edge toughness (slope of the lines) of the as-quarried jasper was 52 percent greater than the heat-treated jasper, as shown in Figure 7. In other words, the heat-treated jasper had improved Figure 7. Top view of edge chips in as-quarried and heat-treated Bald Eagle Jasper. The color change from the heat treatment is amazing. Distance (mm) www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 (Credit: G.D. Quinn.) Lithics Archaeological discoveries reveal that edge chipping was among the earliest of manufacturing processes. Edgechip testing is a way of applying scientific methodology to understanding the activities of prehistoric “engineers” and innovators. Almond and McCormick3 showed the similarities of flakes in a Figure 6. Obsidian glass arrowheads. Force (N) edge chipping was a possible problem. Controlled edge-chipping experiments on cylindrical components compared the performance of two candidate zirconias. Figure 4(b) shows that only a few experiments were necessary to show that a ceria-stabilized tetragonal zirconia polycrystal (TZP) had superior edge-chip resistance to a magnesiastabilized transformation-toughened zirconia (TTZ). Valves are another engine component application for ceramic materials, such as the silicon nitride valve shown in Figure 5. Danzer et al.12 measured chip resistance of the silicon nitride candidate materials and experimented with various edge bevel shapes. They showed that judicious edge beveling can increase dramatically the amount of force necessary to cause a chip to form. This work reinforced Almond and McCormick’s work3 on the effect of edge shape on the measured chipping resistance. J. Quinn and Mohan also found that the direction of the load applied by the indenter matters.13 They used test coupons with 90° edges to show that chips formed with smaller forces when the load angles toward the edge. Conversely, applied force directed toward the bulk, required larger loads before chipping occurred. (Courtesy of A. Tsirk.) Figure 5. (a) Ceramic engine valve.

Chipping of human teeth and teeth restorations is a common problem. workability—it would take less force to chip flakes off the heat-treated stone to shape it. Fracture toughness experiments showed that untreated jasper had an 82-percent higher KIc than the heattreated jasper, corroborating the edge chip results. G. Quinn and Bradt15 have observed the opposite trend in their new work on the mineral novaculite. Heat treating improves the edge-chipping resistance. They believe that prehistoric engineers shaped the tools first, then heat-treated them to improve the chipping resistance of the sharp edges.

Edge chip trends for six dental restorative materials. American Ceramic Society Bulletin, Vol. 92, No. 1 | www.ceramics.org (Credit: G.D. Quinn.) Force (N) Force (N) Janet Quinn, late research scientist with the American Dental Association, pioneered the use of edge chip testing of restoration materials for crowns and bridges.16–20 Other groups21–23 now employ edge chip testing, and it even is used to test human dentin24 and enamel.25 (A short review of edge chip testing applied to dental materials was presented at ICACC’12 (Daytona Beach, Fla.) and will be published in the conference proceedings.26) Although laboratory-scale tests use specific indenters on test blocks with carefully prepared edges, the chips physically resemble some types of in-vivo failures,27,28 as shown in Figure 8. Figure 9 compares edge-chipping results for six contemporary restorative materials.29 Not surprisingly, the yttria TZP has the greatest chip resistance. Nevertheless, in clinical practice zirconia crowns sometimes chip. However, the problem is not with the zirconia core. What actually chips is the thin porcelain veneer on the crown’s outer surface that makes the restoration appear more natural. (A monolithic white zirconia crown would look like a piece of Chiclets gum.) Figure 9 shows that a conventional porcelain and an early-generation glass– ceramic were much less chip resistant. Modern filled composites and glass–ceramics have improved chipping resistances. Figure 10 shows detailed outcomes for a contemporary glass-filled– resin-matrix composite. The Vickers and sharp conical 120° indenter trends are similar, but the Vickers indenter required 28 percent more force to make a 0.5-millimeter chip. This is one example where the data better fit the power law with an exponent of 1.8 than they do a linear trend. Chai and Lawn30 have proposed an indentation mechanics model that predicts power-law behavior, but only for an exponent of 1.5. This is an area of ongoing research. Figure 10. Edge chip results for a glass-filled–resin-matrix composite. The Vickers and sharp conical indenter trends are similar but nonlinear. The inset shows the variation of chip shape with indenter. A sharp conical indenter made the left two chips (stained green), and a Vickers indenter made the right two. 27 Edge chip testing of ceramics (Credit: G.D. Quinn.)

Edge chips in a layered alumina/aluminazirconia structure. strates, and machined or cut edges of components. For example, Figure 11 shows chips in an alumina/alumina– zirconia-layered structure made by tape casting.31 Layered ceramics are used in the electronics industry as multilayer substrates, capacitors, and fuel–air sensors. Laminated structures also are an example of a functionally graded material that can mimic biological structures, such as bamboo plants, seashells, or bones. Figure 11 shows that the layers have dramatically altered the chip shapes compared with those in monolithic ceramics. The chipping resistance dramatically improved,32 too. Edge chip testing is proving its utility in R&D labs, quality-control labs, failure-analysis investigations, and more. As more groups use this simple and versatile method, variations in procedure are proliferating, which may make comparing data difficult. The NPL group prepared a CEN (European) Technical Specification prestandard,33 which offers some guidance for testing and reporting results. It features static edge chipping as described above, but also scratch edge hardness testing. One shortcoming is that it assumes that force–distance data are primarily linear. The reported outcome is an average edge-chipping resistance, ReA (Newtons per millimeter), that is the average of the force–distance ratios for many chips. In the dental field, there is a growing consensus to use either Te (or M) or SE(0.5).21,22,29 About the author George Quinn is a research consultant at the American Dental 28 References Y.

Institutions have to play to win, and no proposals were submitted from California faculty in this round. However, six of the 25 active CAREER awards support junior faculty at California institutions. The Future NSF staff will work with faculty and university press offices to report on the discoveries of present and future awardees through news media, the NSF website, and other channels, including the Bulletin. The NSF’s online news outlets, www.research.gov, and Science Nation on the www.nsf.gov website regularly feature research and education highlights. Also, after the completion of NSF-funded projects, short outcome reports are available on www.research. gov for the public. Looking ahead to 2013, 14 CAREER proposals are under review, with possible EPSCoR cofunding for new awards in those jurisdictions, particularly for researchers new to NSF funding. However, the CAREER program is not the only option for assistant professors, and they often apply to other NSF solicitations and programs. In particular, assistant professors have capitalized on their connections overseas and with industry to secure funding through the NSF’s MWN and GOALI grants.

Herderick T he disaster at the Fukushima, Japan, Daiichi nuclear power plant presented a key question to the materials community: “Are there materials innovations that can profoundly improve the safety of existing light-water reactors?” Fortunately, the answer is “yes” on many fronts, but although there are many promising new materials and technologies, there are still many miles of development and implementation testing to travel on the road to regulatory approval of any new reactor technologies. One example is a study of silicon carbide for a promising new approach to fuel rod safety underway at EWI (Columbus, Ohio; formerly known as the Edison Welding Institute). Although the research remains preliminary, at least on the scale of typical regulator hurdles and industry acceptance, the facility’s work on SiC reactor fuel rod applications has shown positive results, including an evaluation after six months of exposure of an experimental assembly in a test reactor. EWI is not alone in believing that SiC ceramic-matrix composites are a prime candidate for fuel cladding. 32 T.)

There is a broad sense that SiC could provide additional margins of safety in an extreme accident such as Fukushima Daiichi, and there is significant activity in this area of research.1-4 However, transitioning from the current stateof-the-art zirconium alloy nuclear fuel cladding to a SiC composite cladding is fundamentally a materials challenge, and it would represent the biggest shift in light water reactor materials technology since their original design and introduction. Therefore, the ceramic engineering community has a strong part to play in supporting and leading development of enhanced, accidenttolerant nuclear fuels. Background on nuclear fuel cladding and Fukushima Daiichi More than 90 percent of all the nuclear power plants operating globally are of the light-water reactor (LWR) design, which produces heat by controlled nuclear fission and is cooled by water. In the United States, all 104 operating nuclear power plants are LWR designs.5 The main element of LWR fuel is an array of individual fuel rods that are long (approximately 4 meters) and thin (approximately 10 millimeters) composed of a highperformance zirconium base alloy in the shape of a tube. Inside the fuel rods are individual pellets of UO2 fuel that can undergo a nuclear fission chain reaction, which, in turn, generates heat that can be converted to electricity. Fuel rods are assembled into bundles with control rods, and operators place these assemblies in the reactor core where the reaction and energy generation takes place. The control rods, in general, are made of a material, such as B4C, that readily absorbs neutrons. When the control rods are inserted fully, they absorb so many neutrons that the chain reaction leading to heat generation cannot take place. However, even after operators insert the control rods and stop the chain reaction, a certain amount of heat is generated by radioactive decay of atomic fragments generated during the chain reaction. That amount of decay heat is relatively small compared with the overall production of the operating reactor. Nevertheless, it is substantial enough that it must be removed by circulating cooling water for several hours after the reactor is shut down. The danger of this decay heat came into focus when operators could not modulate heat generation in the Japan incident. A narrative contained in the Special Report on Fukushima published by the American Nuclear Society5 sets the stage: “The Tohoku earthquake, which occurred at 2:46 p.m. (Japan time) on Friday, March 11, 2011, on the east coast of northern Japan, is believed to be one of the largest earthquakes in recorded history. Following the earthquake on Friday afternoon, the nuclear power plants at the Fukushima Daiichi, Fukushima Daini, Higashidori, Onagawa, and Tokai Daini nuclear power stations (NPSs) were affected, and emergency systems were activated. The earthquake caused a tsunami, which hit the east coast of Japan and caused a loss of all on-site and off-site power at the Fukushima Daiichi NPS, leaving it without any emergency power.” www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 SiC in nuclear applications The disaster at the Fukushima Daiichi nuclear plant has fueled interest in SiC-based materials as a meltdown-resistant barrier. This is driven by SiC’s excellent thermal and environmental stability, resistance to radiation, resistance to thermal shock and high strength and toughness (especially when incorporated into a ceramic matrix composite). The preference for SiC mainly derives from its stability at temperatures in excess of 2,000°C. This implies that it will not melt under what engineers call “loss-ofcoolant accident” (LOCA) conditions, and, thus, its use could lead to a large increase in existing reactor safety. SiC has several other properties to recommend it. It does not suffer from fretting wear, nor does it react to form hydrogen. And, in addition to the safety improvements, SiC has a lower neutron penalty than zirconium alloys, a property that could allow for improved economics if the same thickness of material can be used in the new cladding.1 The material also may allow for higher fuel burnups (a measure of how much energy is extracted from a primary nuclear fuel source) and reduce the amount of accumulated used nuclear fuel. (Credit: EWI.) For these reasons, SiC fuel cladding is an important strategic technology for advanced nuclear fuels programs. However, a key SiCcladding-related problem—one that heretofore has eluded a satisfactory solution—is the final sealing of rods composed of the material. Although hollow Figure 2.

The challenge is to join a SiC end plug to the SiC cladding tube.6 Background on joining of SiC for accident-tolerant nuclear fuel and EWI work Developing a way to seal a SiC tube is an inherently difficult problem to solve, at least from a joining technology standpoint, and a solution must be engineered with inservice requirements foremost Figure 3.

During the subsequent disaster, reactor technicians could not remove the decay heat from the reactor cores quickly enough. Eventually, the heated zirconium alloy fuel cladding reacted with high-temperature steam to form hydrogen. That hydrogen built up inside the reactor containment building and led to explosions that damaged multiple reactor buildings. The fuel cladding used in the Japanese reactors is a reliable veteran technology and current zirconium alloy cladding technology benefits from nearly 50 years of development and commercial operation. Its use has proved to be economical, and it meets all safety standards of utilities and regulators. However, as evidenced by the Fukushima Daiichi disaster, it can fail catastrophically under extremely rare beyond-design-basis accident conditions. Novel silicon carbide joining for new generation of accident-tolerant nuclear fuels 34 areas are aluminum (with some iron), and the black areas are SiC. Energy-dispersive X-ray spectroscopy mapping and cross sectional images showed that fracture occurs within the silicon bond layer and at the SiC–braze interface in the aluminum-rich areas. Also, knowing that aluminum rapidly forms tenacious aluminum carbides on contact with SiC, leads to the conclusion that a composite, three-dimensional fracture occurred. It is apparent that the silicon has fractured in the “gauge center” of the braze, roughly equidistant from the two SiC substrates. In the aluminum-rich areas, either the top or the bottom face of the SiC has failed, and the fracture is to the positive or negative z direction relative to the silicon area. The fracture of the braze in many different planes has positive implications for damage tolerance. Indeed, investigators observed this experimentally during a three-point bend test, when an initial crack formed: The sample relieved the stress, and catastrophic failure did not appear until they imposed a higher crosshead displacement. Initial radiation testing of joined assembly see how the SiC–SiC assembly would perform in an environment close to that which would be encountered in a nuclear reactor application. As a first step, irradiation testing was completed at the pressurized water research reactor (PWR) at the Massachusetts Institute of Technology. The test was conducted with the typical PWR primary water conditions of 300°C, 1,000 parts per million of boron, and 7 parts per million of lithium at saturation pressure. Researchers did a preliminary examination of the samples after they were in the MIT reactor for a little more than six months. Figure 5 shows an optical image of the samples loaded in the MIT bonding sample test capsule before irradiation. Figure 1 shows an image of a sample after irradiation, and, as is evident, the sample did not fail. During the time in the reactor, MIT estimates that the samples experienced about 11,200 megawatt-hours of energy. Based on typical flux numbers for the facility, that would correspond to a fluence rate of about 3.7 × 1020 neutrons/ (square centimeter per second) (E > 0.1 megaelectronvolts) or about 0.4 displacements per atom (dpa) based on a rule-ofthumb dose/dpa conversion. To put these numbers into context, SiC has been shown to volumetrically swell under irradiation on the order of a few percent when irradiated at 1–5 dpa level, corre- In addition to three-point bend tests, EWI conducted several temperaturecycling tests. Investigators cycled joined assemblies 25 times in air to 350°C, and then to 1,200°C for one cycle. Subsequent mechanical testing and microstructural analysis showed no postthermal cycling changes in the braze joint. Also, one sample assembly was quenched in water after heating to 700°C. Although the braze did crack, the crack-arresting properties of the twophase structure of the braze held the SiC–SiC Figure 4.

The EWI approach employs a multiphase braze alloy interlayer consisting of silicon and aluminum with a two-phase joined microstructure. The proprietary, patent-pending technology has the potential to meet all of the in-service and manufacturing requirements.11,12 The novel aspect of this approach is the use of a hypereutectic mixture of aluminum and silicon. The initial joining interlayer, however, is not a mixed alloy but rather a two-phase mixture of nearly pure silicon with nearly pure aluminum and a small amount of alloying elements. By heating the braze mixture above the melting point of aluminum, but below the melting point of silicon, a distinctive microstructure is formed consisting of plates of silicon with areas of aluminumrich silicon-containing phases. This twophase joined microstructure provides crack-arresting paths that enable high toughness of the joined assembly. To test this novel joining technique, EWI researchers began by joining small monolithic samples of SiC. Engineers accomplished this by joining two 1-inch × 0.5-inch × 0.5-inch blocks of α-phase Hexoloy SiC manufactured by SaintGobain Ceramics with a thin, approximately 10-micrometer-thick, interlayer of the silicon braze (Figure 1). Some of the joined samples were prepared for initial SEM analysis. SEM images of the silicon-only regions of the bond indicated that the braze wetted the interface well and that the bond was pore- and crack-free (Figure 2). SEM images also showed that the interlayer contained aluminum-rich phases interspersed through the bond layer (Figure 3). Next, researchers subjected the samples to mechanical testing. They fractured joined assemblies using a threepoint bend test, and the braze fracture interface was characterized. Figure 4 is a back-scattered SEM image of the braze fracture face. The gray areas are pure silicon, the white (Credit: MIT.) Figure 5.

In future work, EWI researchers will conduct further evaluations of microstructure and mechanical strength of the irradiated samples when they are safe to handle. Once the microstructural effects on the braze design are understood, further irradiation tests will be done that represent new milestones in matching in-reactor service exposure. Figure 6.

Figure 1. Ultra-high-temperature mechanicaltesting apparatus showing the environmental chamber, induction coil, and test frame. Case study: Building an ultrahigh-temperature mechanical testing system By Eric W. Neuman, Harlan J. BrownShaklee, Jeremy Watts, Greg E. Hilmas, and William G. Fahrenholtz Missouri University of Science and Technology students and faculty designed an ultra-high-temperature test system for atmosphere-controlled mechanical testing at temperatures up to 2,600°C. 36 ltra-high-temperature ceramics (UHTCs), such as refractory metal borides and carbides, are candidate materials for use in the extreme environments associated with hypersonic flight, scramjet engines, rocket propulsion, and atmospheric re-entry.1 For example, zirconium diboride- and hafnium diboride-based ceramics are candidates for the sharp wing leading edges of future hypersonic aerospace vehicles where temperatures in excess of 2,000°C are predicted. The ability to test these materials near their expected service temperatures is an important step in their continued development. However, the upper test temperature for most commercial testing systems is limited to about 1,500°C. As a result, little is known about the mechanical behavior of UHTCs at temperatures relevant to the proposed applications. The high-temperature testing lab in the Department of Materials Science and Engineering at Missouri University of Science and Technology recently added atmospherecontrolled mechanical testing capability for temperatures up to 2,600°C. Figure 1 shows the ultra-high-temperature test system, comprising a screw-driven universal test frame, custom-built environmental chamber, and an inductively heated hot zone with a graphite susceptor; it can achieve heating rates as high as 500°C per minute. The environwww.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 Design challenges The system was designed to test at temperatures up to 2,500°C. Choosing induction heating overcame some of the limitations of a commercial graphite- or refractory-element vacuum furnace, such as chemical compatibility with the fixturing and specimens at high temperatures, heating rate limits, and limited atmospheres. Induction heating also allows for changing the hot-zone material and test fixtures depending on the sample material and test atmosphere. Finally, because induction furnaces have higher heating and cooling rates than graphite-element resistance furnaces, the system accommodates multiple test runs per day. The drawback to this approach was that no commercially available systems appeared to meet our design requirements. Students and faculty constructed the system in several stages over a period of about six years. Several components were purchased: the environmental chamber, induction power supply, pyrometer, temperature controller, and load cell. The load frame (Model 33R4204, Instron, Norwood, Mass.) came from another department on campus. Graduate students at Missouri S&T designed and fabricated most of the load train assembly, induction coil, hot zone, and gas-handling system. Graduate students also designed the test fixtures and rigid graphite components, which were fabricated by Graphite Products Inc., Madison Validating the system Heights, Mich.

A proportional integral derivative controller regulates the temperature. A type-B thermocouple measures temperatures below 1,600°C, and a two-color pyrometer measures above 1,500°C. To date, four-point bend tests according to ASTM C1211 (“Flexural Strength for Advanced Ceramics at Elevated Temperature,” ASTM Book of Standards, ASTM International, West Conshohocken, Pa.) have been performed, but tensile and compression tests are possible with proper test fixtures. 37 Case study: Building an ultra-high-temperature mechanical testing system The chamber is purged with argon for 30 minutes, which is enough to change the atmosphere in the chamber twice. After purging, the induction coil is energized. The typical heating rate is 100°C per minute until the temperature is about 100°C below the testing temperature, and the testing temperature is approached at 50°C per minute. A five-minute hold prior to applying the load allows for thermal equilibration before testing. Standard commercial software operates the test frame and controls the displacement rate, as well as capturing the resulting displacement and load. Once the specimen has failed, the induction coil is de-energized, and the furnace cools. Because of the low thermal mass of the insulation, the furnace cools to below 600°C in about one hour. Below 600°C, the environmental chamber can be opened to allow the hot zone to cool more rapidly. Using this methodology, we can test as many as four specimens at temperatures of 2,000°C or above in a typical workday. This system eliminates the barriers that once prevented ultra-high-temperature mechanical testing and makes it possible for us to study the mechanical behavior of UHTCs at the extreme temperatures likely to be encountered during hypersonic flight.

Virkar Distinguished Professor, Department Chair, College of engineering, Department of Materials Science and engineering, University of Utah Failure of Ceramics under Externally Applied Loads and Internally Generated Pressures: Zirconia, a Unique Material Stabilized zirconia exists in two crystallographic forms: cubic and tetragonal. Zirconia has been extensively investigated for various applications that exploit its ionic transport properties, its refractory properties, and its excellent mechanical properties. Solid oxide fuel cells, sensors, electrolyzers, thermal barrier coatings, heating elements, ball bearings, medical implants, etc., are some of the applications. tetragonal zirconia is known for its excellent mechanical properties attributed to the t → m martensitic transformation and ferroelasticity. excellent oxygen-ion conductivity of zirconia is the reason for its use in fuel cells and electrolyzers. in many mechanical and electrochemical applications, zirconia exhibits failure in service under some conditions. the commonly experienced failure is under externally applied loads. increases in fracture toughness and strength achieved through processing, microstructure control, etc., lead to greater reliability. this has been extensively investigated. however, cracking of zirconia also occurs under electrochemical conditions. Such failures occur under internally generated pressures. Although cracking occurs in both types of failures, the origin and mechanisms can be very different in the two cases. Conventional approaches of increasing strength and toughness have little role in mitigating failures that often occur in electrochemical systems. rather, ion and electron transport properties determine whether failures can be mitigated. Additionally, even the mechanism of cracking is different from failures observed under externally applied loads. the two different modes of fracture will be compared and contrasted. in external loading, one seeks solutions to fracture mechanical problems by solving elasticity equations. in electrochemical systems with internally generated pressures, a coupling exists between electrochemical transport (e.g., solution to transport equations) and mechanics. this leads to different cracking patterns. Under external loading, failure is almost always catastrophic (barring subcritical crack growth related issues). however, under internal loading, failure is stable and not abrupt. the two different modes of failure will be compared and contrasted. Bridge Building Award recipient: Tatsuki Ohji Prime Senior research Scientist, national institute of Advanced industrial Science and technology (AiSt) and Designated Professor in the graduate School of Science and engineering, Meijo University Microstructural Evolution and Mechanical Properties of Engineering Ceramics Ceramic materials are composed of a variety of structural elements, including defects, grains, particles, pores, fibers, layers, and interfaces at different scale levels. in terms of size, the structural elements can be classified into four categories: (1) atomic and molecular scale (2) nanoscale (order of 10-6 mm); (3) microscale (order of 10-3 mm); and (4) macroscale. it is possible to realize new or unique performance or markedly improve properties in ceramics, by controlling systematically these structural elements. taking, as an instance, silicon nitride, which is one of the most widely used engineering ceramics, this paper intends to show that the mechanical properties including strength, toughness, and creep resistance can be tremendously improved when the sizes, morphologies, orientation, distribution, etc., of grains and pores as well as grain-boundary structure are carefully controlled. examples are: (1) super strong silicon nitride with >2 gPa strength via refinement and alignment control of grains; (2) porous silicon nitride with high strength (>1 gPa), and high toughness (300–500 J/m2— far higher than that of the dense) via morphology and alignment control of grains and pores; and (3) super-heat-resistant silicon nitride with strength retention up to 1500°C and toughness of approximately 800 J/m2 (double that of cast iron). the paper also focuses on improved mechanical properties via microstructure control for high thermal conductivity silicon nitride, which is expected to be applied as substrate materials in future power devices. 2013 Plenary Speakers Do-Suck Han Director/CAe & Materials research, hyundai Motor Company, r&D Division Nanocomposite Materials for the NextGeneration Vehicles there have been strong moves in recent years to apply advanced materials based on the recent legislative and environmental pressures on the automotive industry to produce light-weight fuel-efficient vehicles with lower emissions. those social pressures have led to a requirement for traditional components to be replaced by advanced materials. nanocomposite materials are expected to be attractive materials that combine the elements of significant weight saving, improved performance, and multifunctionality, such as low friction, high heat resistance and anti-corrosion. the nanotechnology already has been introduced to the automotive components from material scale to structural scale. this has led to a complete reanalysis of the design and manufacturing routes, with the emergence of advanced technologies as a viable process for the production of high-volume, low-cost, high-integrity automotive components. in this lecture the development and application of nanocomposite materials and key technologies will be described and discussed in terms of vehicle performance and cost effectiveness. the research activities described illustrate the benefits of tailoring of design, processing and materials suitable for conventional vehicles as well as ev, hev and FCev. 40 Bruce Dunn nippon Sheet glass Professor of Materials Science and engineering, UCLA Designing Ceramics for Electrochemical Energy Storage Devices the ability to design the chemistry and nanostructure of ceramics is having a profound effect on the performance of electrode materials for electrochemical energy storage. Some of the key advances in this field will be discussed in this presentation. in the lithium-ion battery field, improvements in energy and power densities are attributed to the development of nanoscale materials that exhibit shorter ion and electron diffusion lengths. the development of carbon coatings and core–shell materials represents another significant advance in the design of electrode materials. this approach enables new families of poorly conducting oxides to be used as insertion electrodes. Mesoporous transition-metal oxides also are emerging as an important direction in the energy storage field. the mesoporous architecture provides electrolyte access to redox-active walls and enables higher energy densities to be attained. the energy storage field faces a number of future challenges and these items also will be discussed. www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 1 Symposia Schedule (Schedule was accurate when the Bulletin went to press.

Previously, he was Distinguished University Professor at the University of Maryland College Park. From 1989 to1995, at Bellcore, he initiated research in several key areas of oxide electronics, including ferroelectric nonvolatile memories. His landmark contributions in ferroelectrics came through the recognition that conducting oxide electrodes are the solution to the problem of polarization fatigue, which, for 30 years, were an enigma and unsolved problem. His current research interests include thermoelectric and photovoltaic energy conversion in complex oxide heterostructures. He has published extensively on the synthesis and materials physics of complex oxide materials. He received the Humboldt Senior Scientist Prize and Fellowship to the American Physical Society (2001). In 2005, he was elected a Fellow of American Association for the Advancement of Science and was awarded the David Adler Lectureship of the American Physical Society. In 2007, he was awarded the Materials Research Society David Turnbull Lectureship Award.In 2009, he was elected Fellow of MRS and received the 2010 APS McGroddy New Materials Prize. From December 2010 to August 2012 he served as the founding director of the SunShot Initiative at the Department of Energy, overseeing and coordinating the R&D activities of the US Solar Program. In 2011, he was elected to the National Academy of Engineering.

Waser became director of the Institute for Electronic Materials at the Forschungszentrum Jülich in 1997. Waser is a member of the Emerging Research Devices working group of the ITRS, and he has been collaborating with major semiconductor industries in Europe, the US, and the Far East. Since 2002, he has been the coordinator of the research program on nanoelectronic systems American Ceramic Society Bulletin, Vol. 92, No. 1 | www.ceramics.org within the German national research centers in the Helmholtz Association. In 2007, he cofounded the Jülich-Aachen Research Alliance, section Fundamentals of Future Information Technology (JARA-FIT). Together with Professor Wuttig, he heads a collaborative research center on resistively switching chalcogenides for future electronics (SFB 917), which comprises 14 institutes within JARA-FIT and has been funded by the German Research Foundation (DFG) since 2011. January 25 | 8:30 – 9:30 a.m. Kitt Reinhardt, Program Manager, Air Force Office of Scientific Research Title: Material Science and Device Physics Challenges for Near-Real-Time Adaptive Monolithic Multimodal Sensing Biography: Reinhardt holds a BS and MS in electrical engineering from the State University of New York at Buffalo (1986, 1988). He earned a doctorate degree in Engineering Physics from the Air Force Institute of Technology in 1994 for experimental research in high-energy space radiation interactions with surface and bulk electronic defects and junction current transport phenomena in GaInP p/n junctions. Reinhardt joined the Air Force Research Laboratory in 1988 to research sub-micrometer GaAs X-band microwave device and circuit design. Physics-based modeling, simulation, and characterization of GaAs, GaAs/Ge, and GaInP/GaA/Ge p/n solar cells soon followed, before turning to electrical defect studies in diamond and SiC materials important for high-temperature power device applications. Returning to solar cells in the late 1990s, Reinhardt fostered a series of innovative multijunction solar cell research programs with industry and academia that ultimately resulted in today’s world-record 30-percent efficient triple-junction GaInP/GaAs/Ge solar cells. This solar cell design is used currently on all Air Force and most commercial satellites launched today. For this contribution, Reinhardt and his AFRL research group was inducted into the Space Technology Hall of Fame in 2004. He received a Rotary National Stellar Award for Space Achievement in 2000 and led a definitive National Research Council study on NASA’s Solar Power Program in 2001. Reinhardt was detailed to NASA GSFC in 2002 to coordinate collaborative research in remote sensing, power generation, and radiation-hardened electronics. He returned in 2003 to lead AFRL’s electronics space-radiation effects group employing in-house γ- and X-ray sources, 3D-poisson solver predictive tools, and ab-initio and density-functional modeling methods.

The course load in any engineering degree is always demanding, and each year students such as myself do battle with the tides the seasons bring: September’s new courses, seemingly unlike any others taken before; the eruption of flu in early October; the onslaught of midterms through November; and, finally, December’s final examinations. Repeat this schedule for second term and fill in any extracurricular activities per your desire. It is easy to get swept up in the passing of seasons, to simply focus on “getting by.” There is an immense volume of knowledge supplied to us, and we are consistently surrounded by giants in the field—people who have found their niche in research and actively pursue their passion. It’s hard not to feel dwarfed and, in some respects, lost. Despite enjoying what I am learning and despite many professors giving real-world applications for the materials we study, I often wonder, “Why am I learning this?” As the old adage goes, sometimes you “can’t see the forest for the trees,” or, perhaps more aptly, the micrograph for the grains. 64 One season of the academic year— summer—usually means a break from materials engineering. Two summers ago I worked at a biological sciences company in a fun and interesting job, but I came to realize it was not teaching me what I wanted to know. I needed to find a job that would complement what I had invested three years of my time learning. I needed some perspective; it was time for a materials-oriented summer job. I was fortunate enough to spend last summer as an undergraduate research assistant at McMaster University working under Jeff Hoyt, department chair and associate professor of materials science and engineering. My work involved investigating the diffusion of copper in a lead lattice—an interesting problem because copper diffuses an order of magnitude faster through lead than through other metals, and, although this phenomenon has been recorded since the 1960s, the mechanism responsible for this behavior is still uncertain. I undertook the investigation by employing a type of computer simulation called molecular dynamics. Molecular dynamics is a numerical method for analyzing a system, where the behavior of atoms is predicted according to the solutions of Newton’s equations for motion. I generated several permutations for the system I was interested in, performed multiple runs for various temperatures, and calculate the diffusion rate of copper through lead. I eventually was able to visualize the system, which was my favorite part of the summer—I could actually “see” the crystallographic planes in 3D and on a much larger scale than anything Mary Gallerneault Guest columnist I’d seen previously. It was the computer simulations that easily made the visual scale feasible. I had no prior experience with computational materials science before this research, so the learning curve was certainly steep, but equally rewarding. The summer also granted me a perspective on materials engineering different from what I previously know (having spent the majority of my undergraduate labs looking through a microscope or in front of a polisher). Indeed, I had been, for the most part, ignorant of the power of computational materials science, but have since gained some perspective on the breadth of its applicability: from modeling grain boundaries, to diffusion rates, to dendrite formation. It is a unique and rapidly developing field, and now I look forward to seeing its future applications!
