alone: “Private investment must be
complemented by public investment to
overcome market failures.” To create an
environment conducive to innovation
and to overcome market failures, the
PCAST report recommended a fourpoint plan:
• Launch an advanced manufactur-
At a late June visit to Carnegie
Mellon University in Pittsburgh,
Pa., President Obama introduced the
Advanced Manufacturing Partnership,
which, according to the White House
press release, will invest more than
$500 million to leverage existing programs and proposals to meet its goals.
The press release said that initial
AMP investments will target manufacturing for critical national security
industries, advanced materials development, robotics, improving energy efficiency of manufacturing processes and
“… we can ensure that the United
States remains a nation that ‘invents it
here and manufactures it here’…”
– President Obama.
accelerating the product development
timeline for manufactured goods.
AMP is a response to the first of
four recommendations made by the
President’s Council of Advisors on
Science and Technology in its report,
“Ensuring Leadership in Advanced
Manufacturing.” The report cites
an erosion of domestic leadership in
manufacturing (and the heavy investment of other nations to fill that void),
the advantages of having R&D and
manufacturing located in the United
States, the essential role of an advanced
manufacturing competence in national
security and that, historically, federal
investment in new technologies has
cleared the way for fledglings to become
major new industries.
Four-point plan recommended
The PCAST report concludes that

ing initiative;
• Improve tax policy;
• Support research; and
• Strengthen the workforce.
As recommended, AMP is a government, industry and academic partnership. It will be led by Andrew Liveris,
CEO of Dow Chemical, and Susan
Hockfield, president of MIT, and will
work closely with the White House’s
National Economic Council, Office of
Science and Technology Policy, as well
as with PCAST.
The first team has been picked
already. From industry it will be
Allegheny Technologies, Caterpillar,
Corning, Dow Chemical, Ford,
Honeywell, Intel, Johnson & Johnson,
Northrop Grumman, Proctor &
Gamble and Stryker. Participating
universities are MIT, Carnegie Mellon,
Georgia Tech, Stanford, UC-Berkeley
and University of Michigan.
Government players are DARPA,
DOE, DOD and the Commerce
Department.
The PCAST report recommended
that AMP funding should rise from
$500 million to $1 billion over the
course of four years. While touring
Carnegie Mellon and seeing demonstrations of several cutting-edge technologies developed at the university, Obama
said that it was important for ideas to
have a place to incubate and become
products that can be made in the US
and sold worldwide: “And that’s in
our blood. That’s who we are. We are
inventors, and we are makers, and we
are doers.”
Materials Genome Initiative
Obama also announced the launch
of a Materials Genome Initiative in his
Carnegie Mellon speech. The goal of
the MGI, he said, is to “to help business
develop, discover and deploy new materials twice as fast ... .”
The White House released a white
paper the same day, “Materials Genome
Initiative for Global Competitiveness,”
written by an ad hoc committee of
the National Science and Technology
4
Council (a Cabinet-level cross-agency
entity). The white paper presents a
vision for “how the development of
advanced materials can be accelerated
through advances in computational
techniques, more effective use of standards and enhanced data management.”
Envisioned is a comprehensive collaboration among stakeholders—from
theorists to R&D labs to manufacturers—that will encompass academia,
small and large businesses, professional
societies and government. The goal is
to reduce the approximately 20 years it
currently takes for a new material to go
from lab to application and shrink the
discovery-to-application timeline to less
than five years.
In broad strokes, the white paper
addresses key issues, including materials deployment and acceleration of
the materials continuum by developing a materials innovation infrastructure, achieving national goals with
advanced materials and preparing the
next-generation workforce. A six-point
action plan outlines activities that will
be coordinated by DOD, DOE, NSF
and NIST. The president has written
$100M into his FY12 budget to launch
the MGI (but it is not clear whether
this is included in the $500 million
AMP funding request for FY12).
Computational tools are expected to
be used extensively to get around the
time-consuming and repetitive experimentation that is inevitable but necessary to the development and testing of
new materials. The authors of the white
paper observe that researchers need to
have access to large data sets for accurate simulation and modeling and that
there is no standardized mechanism for
sharing algorithms, models or data at
present.
The NSF and other federal funding agencies require investigators to
include a plan for data management in
their proposals. However, no standard
formats or repositories for the data have
been established.

NASA awards ISS National Lab
contract for management of
2011-2020 experiments
NASA has chosen the Center for the
Advancement of Science in Space Inc., a
new Florida-based nonprofit, tax-exempt
research management organization, to
develop and manage the US portion of
the International Space Station that is
designated a US national lab.
The mission of the ISS NL is to
serve as an asset for US companies,
institutions and other federal agencies
to conduct research in a low-gravity
‘Science to Start-ups’—
Innovation Corps launched
by NSF
In late July, NSF director Subra
Suresh announced a new program, the
NSF Innovation Corps, or I-Corps.
Using the tagline “Science to Start-ups,”
the purpose of the program (supported
with new FY11 funds) is to leverage science and engineering discoveries into
economically useful products and processes.

environment. Based on NASA’s stated
scope of the agreement, CASIS will be
expected to maximize “the value of the
ISS to the nation by developing and
managing a diversified R&D portfolio
based on the US national needs for
basic and applied research and by using
the ISS as a venue for science, technology, engineering and mathematics educational activities.”
According to NASA, about 75 percent of the functionality of the ISS is
part of the US-operated system, which
also includes the space-based assets of the
Japan and the European Space Agency.
The other 25 percent of ISS functionality is operated by other national entities
(Russia, for example).
Additionally, the ISS NL occupies
only a part of the US-operated section. It is difficult to say exactly how
much, because lab space in the ISS is
measured by racks, test equipment and
payload (lab stations attached to the
ISS exterior), rather than by square
feet. Much of the ISS lab space will
continue to be operated and managed
as a NASA research facility.
The management contract has an
initial value of up to $15 million per
year. According to the “Cooperative
Agreement Notice,” (similar to an
RFP), which was issued in mid-February, CASIS-managed experiments
should be underway by Oct. 1, 2011,
and extend through September 2020.
Visit: http://www.spaceflorida.gov/
casis.html n
Holdren, assistant to the President for
science and technology and director of
the White House Office of Science and
Technology Policy, outlined three goals
for the program: “to spur translational
research; to encourage university–industry collaboration; and to provide students with innovation and entrepreneurship training.”
The I-Corps also involves a public–
private collaboration with the Ewing
Marion Kauffman Foundation and the
Deshpande Foundation. Up to 100 projects per year will be funded at $50,000
per project for a six-month effort.
Interested PIs are required to receive
written approval to submit a proposal
from an NSF program director. The
submission window for FY11 proposals is
Aug. 17–Sept. 9, 2011.
Because the program is new and has
some unusual requirements and limitations, the NSF is conducting informational webinars on the first Tuesday of
every month at 2:00 pm (Eastern time).
To be eligible for I-Corps funding, PIs
must have current NSF funding or have
had NSF funding within the past five
years. New funding has been established
for I-Corps, and the first awards will be
made before FY11 closes on Sept. 30.
NSF expects to award $1–$2 million in
FY11 and to grow I-Corps into a $10
million program. Awards will be made
quarterly in FY12 and beyond.
Also in late July, NSF announced the
awarding of $9.2 million in 22 grants
through its Accelerating Innovation
NSF programs
supporting translational research
represented along
the linear innovation continuum,
prior to the introduction of the AIR
and new I-Corps
programs (circa
August 2010).
Research program, which is under the
umbrella of the Industrial Innovation
and Partnerships Division.
Among the 22 funded AIR projects
are:
• Next generation CdTe photovoltaic technology;
• Development and evaluation of
self-powered piezo-floating-gate sensor
chipsets for embedded and implantable
structural health monitoring;
• Si nanoelectronic femtosensor as
ultrasensitive, label-free, protein based
molecular diagnostic platform;
• Transforming nanofiber technology
through scalable fabrication;
• Materials translation for bindered
anthracite briques in foundry cupolas;
• Creation of an ecosystem for biophotonics innovation;
• Enhancing nanotechnology
advances in businesses leveraging energy; and
• Visible-light-activated transparent
antimicrobial coatings.
The AIR program, first announced in
late 2010, was created to help academic
researchers transition proof of concept
innovations into commercial realities.
The AIR program also makes awards
to existing NSF-funded consortia to
help build research collaborations with
business partners. (An example of an
existing NSF funded consortium is the
Center for Glass Surfaces, Interfaces
& Coatings Research at Penn State
University.) n

MCARE wants students who care about energy future
The organizing committee of the Materials Challenges
in Alternative and Renewable Energy 2012 is encouraging as many students as possible to come to the MCARE
2012 conference, which will be Feb. 26–March 1, 2012, in
Clearwater Beach, Fla. Participating in the conference will
give students opportunities to build their professional network, learn more about the materials challenges facing energy technologies and enjoy some midwinter Florida sunshine.
MCARE 2012 has an extensive program related to alternative and renewable energy. Topics include batteries and
energy storage, biomass, electric grid, geothermal, hydrogen,
hydropower, materials availability for alternative energy,
nuclear, solar power and wind. The tutorial-themed sessions
during the first day of the conference are geared toward
nonexperts, allowing students as well as professionals not
intimately familiar with specific topics and applications to
come up to speed quickly.
Networking opportunities
MCARE 2012 is co-organized by four major materials
societies: ACerS, ASM International, TMS and SPE. MRS
and SAMPE also are endorsing the event. This meeting
attracts a more diverse, interdisciplinary range of people
working on energy problems than any other conferences.
Student activities
There will be a student poster session, student mixer and
a design competition for students. Posters will be judged,
and the winners will be presented with awards. Details of
the competition and awards will be posted on the MCARE
2012 website as they become available.

In addition, meeting leaders organized a discussion among attendees on the topic of
“Future Directions for Cementitious Materials.” They asked participants to identify the
most important areas of future research, advancements, education and multidisciplinary
work. The request was enthusiastically embraced by the crowd, which narrowed in on
four potential strategic avenues of interest: multiscale
modeling; hydration mechanisms (particularly in regard
to supplementary cementitious materials); best practices (particularly in regard to data sets, test beds and
cases and building data repositories); and sustainability
(particularly in regard to the use of SCMs). To move
forward on these four avenues, Division leaders say they
and other volunteers will start drafting specific proposals for taking action, such as collaborative efforts, white
papers and funding proposals in time for
next year’s meeting.
In her lecture, “Modeling Hydration
Kinetics of Cementitious Systems,”
Scrivener explored what has and what
remains to be done in the world of modeling cement microstructures. In her opening remarks, Scrivener, who is from the
Ecole Polytechnique Fédérale de Lausanne
(Switzerland), provided a compelling argument about the importance of cements
and concrete to the world, especially to
developing nations, and the challenges of
reducing the CO2 footprint of a material
for which the demand may triple by 2050.

An elusive piece of the alternative
energy puzzle has been storage: How to
save it for when it’s needed or how to
carry it around to use where it’s needed?
In both cases, energy density is the key
parameter and in the latter case, weight
matters, too.
MIT associate professor Yang ShaoHorn’s group appears to have taken a
leap forward in increasing the energy
density using aligned carbon nanofiber
electrodes that can store four times as
much energy on a weight basis than
current-technology lithium-ion battery
electrodes.
The lightweight advantage of
lithium–air batteries (or any metal–air
battery) comes from replacing a solid
electrode, such as those in typical lithium-ion batteries, with a porous carbon
electrode. Energy is stored when lithium ions react with air flowing through
the porosity to form lithium oxides.
The more porous the carbon, the more
efficiently lithium oxides are stored.
A press release reports that ShaoHorn’s group used chemical vapor
deposition to fabricate an electrode of
vertically aligned arrays of carbon nanofibers with 90 percent void space, a big
increase over the 70 percent void space
the group reported achieving last year.
“We were able to create a novel
carpet-like material—composed of
more than 90 percent void space—that
can be filled by the reactive material
during battery operation,” Shao-Horn
says in the press release. That means,
according to Robert Mitchell, a graduate student and paper’s first author, that
“the carpet-like arrays provide a highly
conductive, low-density scaffold for
energy storage.”
The gravimetric energy, which is
the amount of power that can be stored
for a given weight, for these very-lowdensity electrodes is one of the highest
reported to date and demonstrates that
“tuning the carbon structure is a promising route for increasing the energy
density of lithium–air batteries,” said
(Credit: Mitchell, Gallant and Shao-Horn; MIT.)

Betar Gallant.
An unexpected finding is that the
orderly “carpet” structure of the fibers
makes them relatively easy to observe
in a scanning electron microscope, and
the performance of the electrodes can
be monitored at intermediate states of
charge. Being able to directly observe
the process may shed some light on
other vexing issues, such as the degradation observed after many charge–discharge cycles.
These latest results were published in
the August issue of the journal Energy
and Environmental Science (see “Allcarbon-nanofiber electrodes for highenergy rechargeable Li–O2 batteries,”

A press release from IBM describes
work that breaks down two barriers to
using phase change memory materials: the ability to store multiple data
bits, and the ability of the material to
reliably store data for extended time
periods.
PCMMs can write and retrieve data
100 times faster than flash memory and
can endure 10 million or more write
cycles.
In PCMMs, the extent of the phase
change is proportional to the applied
electrical or optical stimulus, and this,
in turn, controls the resistance of the
cell. Taking advantage of the proportionality of the resistance, the IBM
team was able to store multiple bits—
four in this case—in a single cell by
manipulating the applied voltage.
PCMMs have a tendency to “resistance drift” caused by structural relaxation of the amorphous material, which
increases resistance and, therefore,
errors during readout of the data. The
IBM team solved the problem with an
“advanced modulation coding technique that is inherently drift tolerant.”
An IBM test device is storing bits in
a subarray of 200,000 cells in a retention test that has been running for
more than five months, demonstrating
a volume and stability that are of practical use. The IBM press release did not
specify the material.
Brain-like synapses found in
PCMM
IBM researchers in Zurich demonstrated the
first large scale, multilevel cell state retention of a phase-change memory device.
David Wright’s group at the University of Exeter in the UK used a
single cell of PCMM to demonstrate
the ability to store and process information simultaneously, similar to the
way neurons and synapses function in
the human brain. They demonstrated
the simple arithmetic operations of
addition, subtraction, multiplication
and division. Results are published
in Advanced Materials (doi: 10.1002/
adma.201101060)
In an interview published by The
Engineer, Wright, a professor at Exeter,
says PCMM components may be able
to be connected in “networks via
structures akin to synapses, potentially
opening up an entirely novel way of
computing.”
The Exeter group studied GeSbTe

American Ceramic Society were to document and share
technical information related the emerging ceramic and glass
fields, the founders were also wise enough to know that any
group that dared called itself a “Society” also had to have
ways of furthering the social relationships and recognizing
the truly extraordinary accomplishments of its members.
Thus, a tradition of recognizing and elevating the status of
ACerS distinguished members became ingrained in the organization beginning with its first meeting in 1898 when the
Society inducted its first “Honorary Member.”
Over the next 113 years, as relationships grew and traditions took root, ACerS elaborated, refined and expanded its
honors and awards. Some of the awards that arose over the
next eleven decades largely paralleled and ultimately reflected the diversity of the organization and its ten divisions, such
as the Basic Science Division’s Robert B. Sosman Award (see
page 43). Others arose in response to the changing international character of ceramic and glass science, such as the
Richard M. Fultrath Awards (see page 44).
A system of recognizing the greatest service, accomplishments and contributions of Society members also evolved.
The annual tradition of naming and inducting Distinguished
Life Members and Fellows was crafted not only to bring high
honor to the preeminent members of ACerS, but also to
serve two other purposes: to maintain a cadre of “spiritual
guardians” (in the words of Edward Orton) of the Society,
and also to create a career benchmark for young scientists,
engineers and business leaders to aspire to.
The ACerS Distinguished Life Member is the highest
of the Society’s awards, presented to its most inspirational
members who paved new roads in their technical or business
fields while contributing to the growth and programming of
the organization, and guiding its younger leaders. Only two
16
or three members each year reach the lofty expectations set
for Distinguished Life Members and in 2011, ACerS will be
inducting just two: David B. Marshall and Koichi Niihara.
Elevation to Fellow is truly a peer recognition—each
nomination is signed by at least seven ACerS members, and
the new class is selected by the Society’s Panel of Fellows.
Fellows are selected for their outstanding contributions to
the ceramic arts or sciences, either through broad and productive scholarship in ceramic science and technology, by
conspicuous achievement in ceramic industry or by outstanding service to the Society. The 2011 Class of Fellows is comprised of 20 international members (see page 18).
Society president Marina Pascucci, who will preside over
the ACerS Annual Awards banquet, said she is delighted to
be presenting Distinguished Life Members, Fellows and other
awards and says it’s her hope “that these accolades will continue to be a motivation for ceramic and glass technological
advances, and an incentive to scientists and engineers to
maintain the high standard of accomplishment set by those
that we will honor this year.”

Distinguished Life Member Awards
David B.
Marshall is a
principal scientist at Teledyne
Scientific
Company in
Thousand Oaks,
Calif. and an
adjunct professor in the
Materials
Marshall
Department at
the University of California, Santa
Barbara. He earned his BSc and PhD in
physics from Monash University,
Melbourne, Australia in 1971 and 1975
respectively.
Marshall was introduced to the world
of structural ceramics and fracture during two post doctoral positions, first
with Brian Lawn (now at NIST) at
the University of New South Wales
in Sydney, Australia, then with Tony
Evans at University of California,
Berkeley. He joined the Rockwell
Science Center (now Teledyne
Scientific Co.) in 1983, where he has
enjoyed many years of collaboration
with many colleagues, most notably
Fred Lange and Brian Cox. Lange wrote
of Marshall, “David’s major contribution has been the promotion of our
Society to the world through his innovative and fundamental contributions
to reveal our understanding of ceramic
science and engineering.”
Marshall’s research interests have
focused on strengthening, toughening,
and reliability of ceramics and ceramic
composites. In recent years, he has
worked with the Air Force, NASA and
industry to develop textile based composites for turbine, scramjet and rocket
combustion components and thermal
protection systems for spacecraft.
He leads the National Hypersonic
Science Center for Materials and
Structures, a multi-university partnership funded by AFOSR and NASA.
The center is charged with developing key materials that can withstand
the harsh environmental, thermal and
mechanical demands of hypersonic
flight. Other interests include ultra
hard tooling materials for friction stir
welding of steels.
Marshall finds the community
aspects of his career to be deeply satis-
fying. “I found a community to interact
with through The American Ceramic
Society, of wonderfully talented, stimulating and generous people both within
the USA and internationally,” he said.
Likewise, in his present position, for
example, he sees his role as building a
research community between university, industry and government partners.
Dedicated to excellent scholarship,
Marshall has authored or coauthored
more than 200 research papers, two of
which are among the ten most cited
papers published in the history of the
Journal of the American Ceramic Society.
He was a coauthor of one of the 11
papers used to commemorate the
Society’s 110 year anniversary. He is
an associate editor of the Journal of the
American Ceramic Society with 14 years
of service to date and was its editor for
a total of six years. Previous Society
awards include the Ross Coffin Purdy
Award in 1989, Fulrath Award in 1991,
Jeppson Award in 1996, and Sosman
Award in 1999. He is a Fellow of the
American Ceramic Society (Basic
Science Division) and a member of the
National Academy of Engineering.
Koichi Niihara
has been president of Nagaoka
University of
Technology in
Nagaoka, Japan,
since September
2009. Prior to
this, he served
for five years as
a professor and
Niihara
a senator of
NUT. From 1989 to 2005 he was a professor at the Institute of Scientific and
Industrial Research at Osaka
University, Japan, and was awarded the
title of emeritus professor in 2005.
Niihara earned his BE, ME and Dr
of Eng degrees in nuclear science and
engineering from Osaka University.
From 1968 to 1989 he worked as an
associate professor of MRI, Tohoku
University, Japan, was a visiting professor at Virginia Tech and a professor in
the Physics Department of the National
Defense Academy, Japan.
He has conducted important and
innovative research in many ceramic
materials fields, including the fabrication
of massive CVD-Si3N4, SiC and B4C.
Mrityunjay Singh, chief scientist at
the Ohio Aerospace Institute, recalls
Niihara’s early studies in the evaluation
of fracture toughness of ceramics using
the indentation fracture method. “The
footprint he left behind, known as the
‘Niihara’s Equation,’ gained common
recognition among ceramic researchers
worldwide,” he says.
Niihara also gained an admirable
reputation for pioneering the “nanocomposite concept,” which he proposed in 1986. Singh says that prior to
Niihara’s advocacy of this concept of
a new material design, “it was thought
that incorporation of a particle of
another phase into matrix grains would
result in degradation of mechanical/
physical properties. Nowadays, it is
obvious that he was right.”
More recently, Niihara has been a
pioneer and proponent for multifunctional materials, including ones for use
in sensory-type applications.
The Army Research Lab’s James
McCauley described Niihara as “one
of the most creative, productive and
visionary ceramists in the world.”
He has published more than 1000
papers in scientific journals and holds
more than 140 patents.
Niihara has received more than
30 awards, including the Richard
M. Fulrath Award (1983), the ECD
Bridge Building Award (2005) and the
John Jeppson Award (2010), and he
is a Fellow of The American Ceramic
Society. He has organized more than 30
international meetings, including the
successful 3rd International Congress
on Ceramics (held in 2010 in Japan),
where he is a past president.

Medical applications of
zirconium oxide hybrid
materials
In May 2009, the Bulletin first introduced readers to a rapid microscale prototyping process,
two-photon polymerization, and the biomedical
research being conducted by a group led by
Roger Narayan at the Joint Department of Biomedical Engineering, University of North Carolina
and North Carolina State University. Back then,
Narayan reported on his group’s use of organically modified Ormocer, a silica-based biocompatible resin that worked well with 2PP methods.
Since that time, Narayan has looked to expand
the portfolio of materials that could be used to
match the properties of certain biological tissues
being targeted for replacement or to better meet
the requirements of biomedical devices.
One set of materials for use with 2PP that subsequently caught their interest is inorganic–organic
zirconium oxide hybrids because of their unusual
properties, including high hardness, optical
transparency and chemical inertness.
In this report, Narayan and the other authors
review the uses of this hybrid material and 2PP
in tissue-engineering scaffolds, microscale valves,
microfluidic devices, drug-screening devices,
drug-delivery devices, bone prostheses and other
medical devices.
Although a great deal of additional research is still
needed, the potential benefit to the
medical community is high. As the authors note,
the most significant barrier to the creation of artificial tissues and organs is the lack of appropriate
scaffold materials.
I
n this review, we
consider the use
of zirconium oxide hybrid
materials in tissue-engineering scaffolds, microscale
valves, microfluidic devices,
drug-screening devices,
drug delivery devices, bone
prostheses and other medical devices.
Along these lines, we also present
a novel approach for processing zirconium oxide hybrid materials via twophoton polymerization.
Some investigators1 have considered
the use of zirconium oxide hybrid materials for creating artificial bone using
“tissue engineering.” This innovative
strategy for developing artificial bone
and other tissues and organs, uses synthetic scaffolds with cells placed within
a scaffold to facilitate cell development.
The cell-seeded scaffold then is placed
in a bioreactor that provides nutrients
that allow cells to divide within the
scaffold. The scaffold is subsequently
implanted in the body, where the tissue
or organ can resume normal function.
Although the development of
artificial tissues and organs would be
an enormous achievement, the most
significant roadblock to the development of functional artificial tissues and
organs is the lack of appropriate scaffold materials.
Early approaches: Sol–gel

The earliest efforts to use these materials for medical applications took place

in the mid 1990s. Filiaggi et al.2 prepared approximately 60–110 nanometer
thick zirconia thin films on Ti-6Al-4V
alloy (commonly used in medical and
dental bone prostheses) via a polymeric
alkoxide sol–gel approach. These films,
prepared using dip coating, were largely
crack free. However, they found submicrometer scale defects (e.g., pinholes).
When the team annealed the films
to 500°C, they found the materials
contained a mixture of tetragonal and
cubic phases.
Later, Balamurugan et al.3 deposited
0.5–1.0-micrometer-thick polymeric
zirconia sol–gel films on 316L stainlesssteel substrates by means of dip coating.
Cyclic polarization studies indicated
that zirconia sol–gel-coated stainless
steel possessed better corrosion resistance than uncoated stainless steel.
Zhang et al.4 prepared closed microchannel structures, including micromixers and microsplitters, out of a
sol–gel material containing zirconium
propoxide and 3-methacryloxypropyltrimethoxysilane (using 2–3 weight
percent Irgacure 184 as a photoinitiator). They prepared 22–24-micrometer-deep closed channel structures
by attaching two surfaces with corresponding 10–12-micrometer-deep
channels by means of wafer bonding.
A 100–200 nanometer thick copper
layer was utilized for enhancing light
efficiency and reducing light scattering.
The advantage of using sol–gel
materials for microfluidic device
fabrication, such as that mentioned
above, is that these materials may be
processed using conventional solvents
(e.g., acetone and propanol) instead of
proprietary developer solutions.

Organic–inorganic hybrid materials are the products of inorganic polymerization processes, commonly
hydrolysis of metal alkoxides followed by polycondensation of alkoxyl and hydroxyl groups.33 The resulting
materials have three-dimensional networks with a
mixture of organic and inorganic phases that typically
have dimensions on the order of 1–100 nanometers.
The organic groups control porosity and limit
shrinkage by filling the gaps in the inorganic oxide network,34 and the small dimensions of the component
materials can lead to optical transparency.33 Properties
of the components can be independently optimized.
For example, the electronic and optical properties of
these materials may be modified through incorporation
of conductive polymers and organic dyes, respectively.33
There are two types of hybrid materials: “class I,”
in which weak interactions (e.g., ionic bonding, hydrogen bonding or van der Waals forces) provide structural cohesion, and “class II,” in which ionic–covalent
bonds or covalent bonds provide structural cohesion.5
Hybrid materials have been prepared using aluminum, cerium, molybdenum, silicon, tin, titanium, tungsten, vanadium and zirconium,5 that can be readily
modified with dopants25 and can incorporate functional
groups through guest–host or side chain–main chain
methods.26
Researchers have included biologically relevant
materials within hybrid materials and have, for
example, incorporated silver within triethoxysilane as
well as tetraethoxysilane-terminated poly(ethylene
glycol)-block-polyethylene materials prepared by
means of a sol–gel process.7 These transparAmerican Ceramic Society Bulletin, Vol. 90, No. 7

hydrogen bonding between Zr–OH

incorporated ampicillin and then demonstrated (in simulated body fluid) that
ampicillin release occurred in two stages: an initial burst phase followed by a
lag phase. In addition, they immersed
the sol–gel materials into simulated

of hydroxyapatite had formed on the

Sol–gel processing of hybrid materials provides
several advantages, including well-controlled compositions plus easy processing and modification.28, 33 In
addition, it is usually performed under atmospheric
pressure,6 and the polymerization of the organic
groups can occur at low temperatures.34 Sol–gel
materials prepared can be deposited on a wide variety
of substrates,6 and several methods are commonly
used for depositing these coatings, including dip
coating, electrophoresis, spin coating and spraying.28
Further, sol–gel processing is compatible with industrial use because of low equipment costs.2
Zirconium oxide sol–gel materials
Zirconium oxide hybrid materials have been
considered for a variety of technological applications
because of their high transparency to visible light as
well as near-infrared light, high refractive index and
large optical band gap (5.1–7.8 electron volts).35
Another plus is that, unlike titanium oxide, catalytic
photodegradation of organic materials is not a concern
with zirconium oxide.34
Early work on zirconium oxide-based sol–gel
materials involved fabrication of waveguides for optical
and sensing applications. For example, a soda-lime
glass coated with zirconium oxide (using a zirconium
propoxide precursor) exhibited an amorphous structure
and 80 percent transmission of visible light.36
One of the authors of the accompanying paper,
Roger Narayan, explained that, for biomedical applications, the advantage of zirconium-containing hybrid
materials is largely based on their high mechanical
stability and strength. He said the properties stiffness and hardness correlate directrly with zirconium
concentration in these materials. Zirconium:silicon
inorganic–organic hybrid materials containing up to
10 percent zirconium can have a hardness values and
Young’s modulus values of 90–530 megapascals and
1.5–6.0 gigapascals, respectively.
Narayan said in an interview with the Bulletin that
because of these mechanical properties, the use of
zirconium oxide in medical devices, particularly bone
prostheses, is generally of interest. For example,
Kokubo et al.37 showed that zirconia surfaces
immersed in simulated body fluid form apatite, a
phosphate material similar to bone mineral. In addition,
zirconium oxide sol–gel materials can provide high
wear and corrosion resistance to medical devices.7
Several investigators, including the authors, have
recently examined use of zirconium oxide hybrid
materials for medical applications that were prepared
using sol–gel approaches and then modified using
two-photon polymerization, a laser-based process.
Narayan said, “With 2PP, many of the traditional
beginning materials have come from microelectronics processes, but are not optimized for biomedical
processes. Our goal is to try to better match the properties of tissues we are trying to replace, or to better
meet the requirements of the biomedical device we
are trying to build. … That is really the guiding aspect
behind the work: Trying to find materials that have
different properties and better fit for med applications.
In this case, our requirements were to find a material
with higher hardness and stiffness.”
Narayan said the bone-related uses are the most
important potential biomedication applications for
zirconium oxide hybrid materials, but there are more.
“There are other ideas for uses, such as structures
that are scaffolds. It is easy to imagine applications,
such as drug-delivery devices and sensors, that would
benefit from the higher hardness and stiffness we can
achieve,” he said.

Medical applications of zirconium oxide hybrid materials
Rapid prototyping with twophoton polymerization
Several investigators recently have
examined the use of a rapid prototyping method known as two-photon
polymerization to create structures out
of zirconium oxide hybrid materials for
medical and other technological applications.9, 10 The 2PP method involves
fabrication of a structure with microscale
and/or nanoscale features in an additive
manner from a computer-aided design
model. Goeppert-Mayer11 theoretically
proposed multiphoton absorption (a
single quantum event involving interactions between more than one photon
and either a molecule or an atom). In
subsequent work, Kaiser and Garrett12
experimentally demonstrated twophoton excitation, and they formed blue
light (l = 425 nanometer) by irradiating
CaF2:Eu2+ with ruby laser light (l = 694

that the yttrium segregation at grain

Recent efforts have focused on using
2PP to fabricate medically relevant

materials. For example, Zukauskas et al.31
used a sol–gel process with Ormosil to
make 3D microscale structures. Several
of these 2PP structures were based on
fluorescent dye-doped Ormosil materials
(dopants included coumarin 152, DCM

hybrid sol–gel. These microvalves were
designed for use in small veins, allowing blood flow in one direction and
preventing blood flow in the reverse
direction. They created one of these
valves using a scanning speed of 100
micrometers per second, a hatching step
of 1 micrometer and a step height of 7
micrometers (Fig. 3). The dimensions
of the device were comparable to those
of the corresponding 3D computeraided design model. Importantly, the
valve’s internal cavities did not exhibit
stair-step features, a result attributed to
the vertical nature of the surface as well
as to the material resolution. This group
created another valve using a scanning
speed of 400 micrometers per second,
a hatching step of 0.2 micrometer and
a step height of 1.6 micrometers. (The
interior piston rod within this device
was manually actuated using a needle.)
Building a tissue-engineering
scaffold
In our group’s recent work, we used
2PP to create scaffolds for tissue engineering in a layer-by-layer manner out
of a zirconium oxide hybrid material
28
using an experimental approach previously described by Ovsianikov et al.27
We prepare the scaffold by beginning
with a 20:80 zirconium:silicon sol–gel
material containing 2 weight percent
Irgacure 369 initiator. To remove
aggregates prior to use, the material
is passed through a 0.2 micrometer
syringe filter. Then, we pipette 60
microliters of material onto glass cover
slips, which are left overnight. We also
pretreat glass slides in a plasma etcher,
spin coat with TI Prime adhesion promoter and bake at 100°C for 10 minutes to form a gel.
For the next step of the 2PP process, we place the zirconium oxide
hybrid material gel on an inverted
glass slide. Next, we focus the laser
beam—a Ti:sapphire laser operated
using a 140-femtosecond-pulse width,
a 80-gigahertz repetition rate and
a 780-nanometer central emission
wavelength—on the gel using a 103
objective lens. Several previous studies7, 25, 26, 28 involving 2PP of zirconium
oxide hybrid materials used 503 or
1003 objective lenses. However, use
of a lower-power objective lens hastens
processing of larger structures. (Higherpower objectives are unsuitable for creating relatively large structures, such as
tissue-engineering scaffolds, because of
radial laser energy degradation.32)
For cylinder fabrication, we use a
galvanometric mirror scanner, plus
linear stages that enable movement
between the cylinders. Movement of
the stage is guided by a .STL format
drawing, which specifies parameters
such as cylinder diameter, cylinder
spacing, cylinder height and layer number. We calculate the initial position by
multiplying the scaffold layer number
by the cylinder height without overlapping with the next layer. This approach
prevents blocking of the beam by previously polymerized material. Following
the 2PP, we use propanol to remove
unpolymerized material.

scaffold is composed of an array of

tains eight cylinders. We prepared this
scaffold using a z-spacing of 60 micrometers, an outer cylinder energy of 320
milliwatts and an inner cylinder energy
of 300 milliwatts. Figure 4(b) shows
three hexagonal tissue-engineering scaffolds with two, three and four layers.
Figure 4(c) shows a microcomputed
tomography scan from within one layer
of a seven-layer tissue engineering scaffold, which shows good cylinder-to-cylinder uniformity within the scaffold. We
were able to uniformly and completely
remove unpolymerized material from the
interior region of the scaffold.
Using 2PP to build these scaffolds
from zirconium oxide hybrid is not
without difficulties. One challenge
associated with increasing the dimensions of the scaffold is that burning one
portion of the structure may result in
loss of the entire structure. Another
2PP challenge is that overdeveloping
the structures can cause embrittlement
and/or fracture.
There is a benefit from the geometrical features of hexagonal scaffold shown
in Fig. 4(b), particularly the parallel
arrangement of the cylinders. These
features facilitate processing of replica
structures by means of an indirect rapidprototyping approach. For example, we
can make a negative structure out of
polydimethylsiloxane from a zirconium
oxide hybrid material master structure by
introducing liquid polydimethylsiloxane
into the cylinders of the master structure
from above. We can subsequently use
this negative structure to prepare replica
structures out of the zirconium oxide
hybrid material. Indeed, Fig. 5(a) shows
a scanning electron micrograph of a
portion of the replica tissue-engineering
scaffold, which contains an array of
hollow cylinders with good cylinder-tocylinder uniformity and good correspondence between the features in the master
structure and the replica structure. The
point here is that a polydimethylsiloxane
negative structure can be used to create
multiple replica structures in a rapid,
cost-effective manner.21
In addition, we have prepared 3D
grid structures for evaluating cell
behavior using 2PP and zirconium
oxide hybrid material (Fig. 6(a)). These
grid structures may serve as miniaturized versions of conventional well
plates for drug-screening applications.
For example, one cell or several cells
may be placed within each small-scale
well (Fig. 6(b)) for examining cell
behavior in response to one or more
pharmacologic agents over time.
The road ahead
Use of zirconium oxide hybrid materials in medical device manufacturing
will require commercialization- and
translation-related challenges to be
overcome. For example, it would be
beneficial to be able to incorporate
additional types of biologically active
materials within zirconium oxide hybrid
materials. The mechanical properties
of zirconium oxide hybrid materials
prepared using commercially relevant
processing parameters need to be considered. In addition, we must evaluate
the compatibility of the organic moieties within zirconium oxide hybrid
materials with sterilization processes.
Another hurdle will be developing
novel approaches for processing of these
materials over large areas. Finally, zirAmerican Ceramic Society Bulletin, Vol. 90, No. 7
conium oxide hybrid materials should
become cost competitive in comparison
with conventional bioceramic materials.
Zirconium oxide hybrid materials
may attain commercial importance if
these challenges are surmounted.

Research Exchange program builds
research, opens eyes to world
by Amy White
The aim of IMI-NFG’s Research Exchange is to
encourage and facilitate international collaborations that will lead to creating new applications and
opportunities for glass. Since 2004, the IMI-NFG
program has supported more than 115 exchanges,
involving 25 countries in addition to the United
States.
Participants are graduate students, postdoctoral
researchers and faculty members from the US and
abroad who spend three to six months in another
country conducting research, usually in university laboratories, where they often build lasting relationships.
“They are able to extend their research with
facilities they may not have at home, they get new
ideas working with a complementary group,” said
Himanshu Jain, IMI-NFG director and professor
of materials science and engineering at Lehigh
University. “They also learn what it is to do international research, to get a sense of an international
environment and the local culture, to prepare them
to be a world-class scientist.”
The year-round program, funded through the
National Science Foundation, provides funding for
travel, housing and living expenses for participants
from the US. It also reimburses for local expenses of
researchers from abroad (their international travel
is usually supported by the sending institution,
unless they are from developing countries). A small
amount of funding also may be available to the US
host group for supplies and equipment required for
visitors’ research.

n today’s global marketplace,
it is more important than ever
for students and researchers to gain
an international perspective. Some
are doing so through the Research
Exchange program offered by the
International Materials Institute for
New Functionality in Glass based at
Lehigh University.
Shaojie Wang tours the Giza pyramids during his Research Exchange in
Egypt.
“The exchange is an opportunity or a conduit for a long-term
relationship, not just a student
visit,” Jain added.
The NSF supports five
International Materials Institutes
around the country to enhance
international collaboration
between US researchers and
educators and their counterparts
worldwide and to advance materials research. (see page 33) The
IMI-NFG is the only such institute to focus on a single class of
materials, in its case, glass.
Success stories
Allison Wilhelm Scott, 30,
now an applications engineer
with BioVigilant Systems,
a producer of instantaneous
microbial detection systems in
Tucson, Ariz., said her Research
Exchange experience was beneficial for her career in industry.
Scott participated in three
exchanges while a graduate student at University of Arizona.
During the exchanges, she conducted research at University of
Rennes in France, synthesizing
and developing chalcogenide
glasses for use in biological sensing applications.
“I would go to the University
of Rennes to make different
glasses and try to optimize the
glass composition and polish different optical components and
bring them back to UA for testing to detect viruses in different
water sources,” she said.
Upon completing her doctorate in materials science and
engineering, she worked at a
small startup biotech company
that used polymer science to
develop drug infusion pumps,
and now is at another biotech
company. She works with scientists and engineers from several
countries.
“The opportunity to live in
another country is very beneficial in terms of having the
opportunity to interact with
people from different cultures
and different languages,” said
Scott, whose current employer is
owned by a Japanese company.

and Estonia through the program.
Participants have come to the US
from Australia, South Korea, Ukraine,
Brazil, Japan, China, Portugal, Italy,
Egypt, Finland, Greece, Hungary, Czech
Republic, Nigeria, India, Senegal,
Russia, Spain, Bulgaria and Denmark.
Participation in the program led to
research and employment opportunities
for K.V. Adarsh, 31, who traveled from
India to spend five months at Lehigh
University, work with Jain and do
research with lasers and chalcogenide
glasses. He then completed his doctorate at Indian Institute of Science,
Bangalore, before doing postdoctoral
fellowships in Germany and Israel.
“It was a success story for me,” said
Adarsh, who is now an assistant professor at Indian Institute of Science
Education and Research, Bhopal. “The
program helped me to get very good
postdoc positions, and then I started
a job.” Adarsh plans to send one of
his students, Amiya Ranjan Barik, to
Lehigh to participate in an exchange.
“This will give him a broader perspective, too,” said Adarsh, who has
continued his own collaboration with
Jain. The two have published four
research papers together.

“The collaboration continues,”
Adarsh said. “It is a long-term scenario
now.”
So far, about 42 percent of participants in the IMI-NFG program
have been graduate students, with
an additional 40 percent faculty and
17 percent postdoctoral researchers.
Several graduate students and postdoctoral researchers have participated in
multiple research exchanges and some
exchanges have resulted in two-way
collaborations between institutions.
Jain said about 200 publications in
peer-reviewed journals have resulted
from the international exchanges.
Students also have presented findings at
national and international conferences.
Unique opportunities
For Iolanda Santana Klein, 26,
participating in an exchange to the
US from her native Brazil resulted in
pursuing doctoral studies in the nation.
During her exchange, Klein worked
with Jain and Andriy Kovalskyy, a
research associate at Lehigh University,
on X-ray photoelectron spectroscopy
analysis of tungstate-phosphate glasses
containing silver nanoparticles.
Later, while presenting the research
she developed during her exchange at
the Physics of Non Crystalline Solids
conference in Brazil, she met C. Austen
Angell, professor of chemistry and biochemistry at Arizona State University.
“I found myself quite impressed with
her,” said Angell, who encouraged her
to pursue graduate studies in the US.
Angell is now Klein’s mentor in
her doctoral studies at Arizona State
University, where she is part of his
research group working on providing
electrolytes for lithium batteries.
“All of my best students have participated in one way or another in an
international collaborative program,”
Angell said. “The IMI-NFG Research
Exchange program is one example of
such an opportunity that allows students with initiative to come to the
US, and supports our more outgoing
students to go elsewhere. I think it’s
always a real important growing opportunity for students, and I strongly recommend it.”
Klein, who plans to become a faculty member in Brazil, said the experience of living and working within
an American university gave her the
ability and confidence to return as a
graduate student. “The best part of

Research exchange program
Graduate student learns about lasers and life in Japan
For Lehigh University doctoral student Adam
Stone, spending nine months in Japan meant
rare opportunities to work with femtosecond
lasers, improving his Japanese language skills
and experiencing a different culture.
The 25-year-old graduate student participated in three IMI-NFG Research Exchanges
through spending summers at Kyoto University
in 2008, 2009 and 2010.
“It really has widened my perspective,”
Stone said. “It’s one thing to try to imagine
what it would be like to go somewhere else,
but actually doing it, getting to see how other
people live somewhere else in the world, is
humbling. You go from a world where you are
comfortable and can communicate easily to a
world where it takes some effort to navigate
and communicate. But, it challenges you to
rise to that.”
Stone is working on a project to create
optically active single-crystal architectures in
glass using femtosecond lasers. Through the
exchange, he used Kyoto University’s femtosecond laser facility and worked in the lab of
Kazuyuki Hirao, professor in the university’s
Department of Material Chemistry.
“Hirao’s lab is one of the more advanced
labs in the world as far as laser processing
and research,” Stone said. “They have a type
of laser there we don’t have at Lehigh.” Femtosecond lasers emit intense ultrashort pulses
in the domain of femtoseconds. Stone used
the lasers to create crystals inside glass.
Laser crystallization of glass has potential
applications in fields such as telecommunications and optics, where certain types of
crystals often are needed for their particular
nonlinear properties that glass doesn’t have.
Using a laser, one can pattern lines and arrays of such crystals specifically where they
are needed, introducing nonlinear optical
properties into glass, while taking advantage
of its ease of production and formability. While
a typical laser can make crystals near the
surface of glass, with a femtosecond laser,
researchers can create crystal architectures
inside glass in three dimensions. Such glass–
crystal composites could be used to replace
existing optical components, are well-suited to
integrated optics and making more compact
optics, and could lead to new optical devices
such as optical memory systems, Stone said.
Stone created glass samples at Lehigh,
which he took with him to Kyoto for the laser
experiments and is continuing to analyze back
at the university.
“My research would have looked a lot
different if I hadn’t gone on the exchanges,”
32
Stone said. “I would be able to continue laser
crystallization but not be able to explore
femtosecond lasers and three-dimensional
patterning of crystals.”
Stone remains in touch with researchers
at Kyoto University, with whom he has coauthored two journal publications.
“It was a good way to make an international
connection,” Stone said.
A cross-cultural experience
Stone’s interest in Japan developed before
he participated in the exchange program.
He enjoyed Japanese animation, studied the
martial arts of Shinkendo and Aikido and
took Japanese-language classes. His fiancée,
whom he met pursuing his bachelor’s degree
in materials engineering at Iowa State University, is Japanese.
Still, communicating in Japanese proved his
largest challenge during the exchanges. While
researchers in Kyoto University’s labs spoke
English, most people he encountered outside
the university did not. But, the challenge of
communicating improved Stone’s Japanese
language skills and along the way he gained
a worldwide perspective and absorbed Japanese culture, architecture and history, he said.
The experience also made his professional
goals feel more attainable. Stone wants to
work in Japan after completing his doctorate,
likely in academia, but possibly in industry or
a government lab.
“Being there first hand, experiencing the
country, working at the university and meeting
people there makes the idea of actually living
and working there seem a lot more tangible,”
Stone said.
He encourages students to apply for the
Research Exchange program, which supports
international exchanges for graduate students,
postdoctoral researchers and faculty members.
“I think the chances of being chosen are
probably better than people might expect,”
Stone said. “They are always looking for applicants and IMI-NFG Director Jain really feels
strongly about promoting these international
collaborations, especially for students, and
getting them some international experiences
and connections. It really is a good experience
and it really challenges you in a good way to
get a little outside your comfort zone.”

the exchange for me was the whole
living–studying–researching abroad
experience, in one of the best materials
research labs in the country,” she said.
For Shaojie Wang, 31, a doctoral
student in materials science at Lehigh,
participating in the exchange meant
being able to work in labs with capabilities different from his home university. Wang spent his exchange at
Alexandria University in Egypt, where
he tested porous glass samples for invivo response in rabbits in its tissueengineering laboratory.
“Our project is a nano bioactive
scaffold which is used for medical purposes,” Wang said. “At Lehigh, the
chance of in-vivo animal testing is
very limited. We have a facility here
for in-vitro testing but we don’t have
the right kind of animal facilities. They
have more testing facilities at AU and
they are experts in that.”
Wang created his glass scaffolds in
Lehigh labs using a process developed
by another IMI-NFG postdoctoral
researcher, Ana Marques, while visiting the university from Technical
University of Lisbon, Portugal, where
she was a member of Rui Almeida’s
research group. Wang brought his
specimens to AU to test. The Lehigh–
Alexandria–Lisbon team’s findings were
published recently in an international
journal on materials for medicine.
“I learned a lot from the experts
there,” said Wang, who knew little
about in-vivo testing before the trip.
Patras in Greece.
He worked with Sabyasachi Sen,
associate professor of chemical engineering and materials science at UC
Davis and head of the Amorphous
Materials Research Group. “He was
always by my side, showing me things,
how to prepare materials, how to work
in the NMR lab, how to acquire NMR
signal and how to interpret it,” Nasikas
said. “The students at UC Davis were
also really helpful and made me feel
like home from day one.”
Nasikas and Sen have kept in touch
and authored two published papers.
“It was quite productive and quite
fruitful,” Sen said of the collaboration.
“He taught us things, we taught him
things. … And that’s the best outcome
of such exchanges, that it goes both
ways and both sides benefit.”
Applying for an exchange
(Provided by Shaojie Wang)
Research Exchange grants are awarded based on the relevance of submitted
proposals to the IMI-NFG’s goal of
developing glasses with new functionality and training young professionals for careers in glass as well as their
potential to generate new interactions.
Applications are accepted year round.
They must be submitted by the person who intends to travel and use the
funds. Applicants must submit
a “Proposal for International
Research Exchange
Collaboration” form (available
on the IMI-NFG website, www.
lehigh.edu/imi) and include a
brief proposal and a letter of
commitment from the hosting
investigator.
The exchange is not the
only IMI-NFG program to
assist students and others
achieve international experiences. The IMI-NFG also offers

“I learned how they do the operations,
how they prepare in-vivo samples, how
to interpret experiment results. … For
life, I learned a lot of the culture in
Egypt, went to the pyramids, which was
exciting to see, talked with people and
made some friends. It was really an eyeopening trip.”
The exchange benefited researchers at both universities, Wang said.
(Alexandria University is an example
of a two-way collaboration, because
AU dentist and researcher Ahmad
Rashad Elsebahy spent his exchange at
Lehigh).
Researchers also learned from each
other’s expertise when Nektarios
Nasikas, 30, of Greece, did an
exchange at University of California,
Davis, where he is now on his second
exchange.
Nasikas investigated a new class of
yttrium aluminum garnet laser material at UC Davis, based on samples
he brought with him, and he learned
nuclear magnetic resonance spectroscopy techniques.
“To be exposed to the NMR technique was really important to me to
observe and it added a lot to my knowledge of structural studies for glasses,”
said Nasikas, who is pursuing a doctorate in materials science at University of
Nektarios Nasikas at the Laboratory of
Applied Molecular Spectroscopy at ICEHT/FORTH in Patras, Greece, placing
samples in a levitator to prepare glassy
samples. He wears glasses as a precaution because of the black body radiation
caused by temperatures above 2,000°C
achieved with this technique.
a goal of building new international
collaborations with domestic teams.
The IMI-NFG also has the Research
Experience for Undergraduates in Glass
program at Lehigh, Pennsylvania State
University and abroad.
Jain, director of the IMI-NFG, said
that today’s challenges are so large
that individual countries can’t handle
them alone and need to work together.
“With globalization, individuals,
including scientists, have to be more
knowledgeable about the conditions
and opportunities in other countries,”
he said, “to solve the grand challenges
by working collaboratively.”

by an acoustic microimaging systems, propagates through virtually
all high-performance
ceramics with relatively
low attenuation. With
AMI, typical sample
thicknesses range from
less than a millimeter
to perhaps a few centimeters, depending
on the attenuation of
the specific material.
Attenuation is higher
if the porosity of the
ceramic is abnormally
high.
The ultrasound of an AMI is
pulsed into the ceramic by a scanning transducer, and ranges in
frequency from 5 megahertz to
400 megahertz or more. AMI frequencies up to 100 megahertz are
typically referred to as very high
frequencies, while those above 100
megahertz are known as ultrahigh
frequencies. Higher frequencies
provide more spatial resolution
in the acoustic image but have
less penetration. AMI typically
uses frequencies from 30 to 100
34
megahertz when imaging advanced
ceramics.
Other technologies use ultrasound at lower frequencies also to
test or image a variety of materials, including samples of advanced
ceramics too large for AMI. For
example, ultrasonic testing, or UT,
can be used to test the integrity
of metals and other materials,
and its frequencies range from 0.5
megahertz to 15 megahertz and
occasionally higher. There is thus
some overlap between AMI and
UT. There also are acoustic imaging systems that use frequencies
from 500 megahertz to 2 gigahertz
and perhaps higher. They have
almost no penetration but provide
extremely high resolution of surface features and features within a
few micrometers of the surface.
The choice of an UT or
another imaging system for a given
sample involves consideration of
physical dimensions, penetration
needed and resolution needed.
AMI is thus used for small samples that require relatively high
resolution and that are not highly
porous.
High-performance ceramics typically are imaged by AMI
to determine nondestructively
whether internal flaws, such as
voids or cracks, are present and to
image those flaws. Imaging usually is conducted in the reflection
mode, where echoes are reflected
from internal features, such as
defects, and are collected by the
(Credit: Sonoscan)
transducer above the sample. But, AMI
also may operate in transmission mode,
where ultrasound is propagated entirely
through the sample to make acoustic
shadows of gap-type defects.
Ultrasonic reflection
The reflection mode was used to
image the sample diagrammed in Figure
1, a circular alumina disk 19.53 millimeters in diameter and 9.95 millimeters
thick. In reflection mode, a pulse of
ultrasound is launched from the transducer. As long as the pulse is traveling through homogeneous material it
will send back no return echo signals,
although it will gradually be attenuated
by the alumina. Because there are no
return echo signals to be collected by
the transducer and analyzed by software, the acoustic image will be uniformly black.
But, if at a given x–y location, the
pulse encounters a crack (or a void or a
delamination or any other type of gap),
a very strong reflection will occur. The
amplitude of the reflection at any material interface depends on the density
and acoustic velocity of the two materials involved.
The density and acoustic velocity of
advanced ceramics are typically fairly
high. A gap, however, is filled with air,
or perhaps a vacuum—but not a solid
material. The density of air is nominally 0.001225 grams per cubic centimeter
at 15°C. Its acoustic velocity is essentially immaterial because, although lowfrequency sound travels well through
air, ultrasound is completely attenuated
almost immediately. If the ultrasonic
pulse encounters, for example, two solids, such as a layer of metal bonded to
the ceramic, some portion of the pulse
will be reflected—15 percent perhaps,
or 35 percent, or 60 percent, depending
on the density and acoustic velocity of
the two solid materials at the interface.
But, when an ultrasonic pulse propagating through a solid material meets a
gap, the reflection is more than 99.99
percent.
The scanning transducer collects
these very-high-amplitude return echo
signals from the entire area of the gap.
If there are no other material interfaces,
Fig. 1. The alumina
disk imaged acoustically at 50 gates
(depths).
most of the acoustic image will be black
(no signal) and the gap will be bright
white (highest amplitude signal). Even
if the gap’s vertical extent is smaller
than 1 micrometer, pulse reflection is
essentially total.
It is the reflection from material
interfaces that distinguishes ultrasound
from X-ray, which, except in special circumstances, is not reflected. X-ray can
reveal fine detail, but its transmission is
governed by the density and bulk of the
various materials in the sample. X-ray
may detect a void if the void has sufficient three-dimensional volume, but
it cannot detect a thin crack or delamination because such defects are too
small to interact with the X-ray beam.
Ultrasound and X-ray are, therefore,
complementary investigative methods.
Because the reflected ultrasonic energy travels through materials at a known
speed, the acoustic image can be limited
to those echoes from a desired depth,
while excluding echoes from other
depths. For example, in a bonded material, the desired depth likely will be the
bond zone. If the acoustic image of the
bond is a uniform shade of gray of an
intensity that matches the anticipated
percentage of reflected energy, then the
bond has no defects. White areas in the
gray bond image indicate gaps.
For some samples, it is desirable to
image the entire thickness, or nearly
the entire thickness. This is the common method with multilayer ceramic
chip capacitors, millions of which are
imaged acoustically for use in highreliability applications. A “gate” is set
to capture those echoes from just below
the top surface of the capacitor to just
above the bottom surface. Any gap
within the active layers of the capacitor will be bright white in the acoustic
image. Functionally, the precise depth
of the gap does not matter, because it is
capable of causing an electrical short at
any depth. Capacitors having a gap at
any depth are rejected for high-reliability applications.
It is possible to set very thin gates
and to set multiple very thin gates to
achieve nondestructive layer-by-layer
analysis of a sample. The gates are
set by marking beginning and ending
points on the on-screen waveform of
a single pulse and dividing the desired
depth into a number of gates of equal
time duration (and depth). During a
single transducer scan of the sample,
what software records at each x–y coordinate is not a single broad echo but
20 or 50 or 100 very thin echoes. The
output will be 20 or 50 or 100 acoustic
images that display the internal features
of the sample at each depth.
Multilayer imaging of alumina
For example, the sample circular
alumina disk shown in Figure 1 had
a diameter of 19.53 millimeters and a
thickness of 9.95 millimeters. At the
center of the disk was a circular hole
having a diameter of 4.02 millimeters.
For acoustic imaging purposes, the
waveform was divided into 50 equal
gates extending from the top surface to
the bottom surface. Spatially, each gate
had a thickness of 0.199 millimeters.
The result of imaging was a series of
50 acoustic images, each showing the
internal features at a specific gate. (It is
possible to set gates considerably thinner than those used here, i.e., the number of gates could have been set at 100
or, depending on the material properties and acoustic frequency, even 200.)

Grasping Excellence: Opportunities for Science and Engineering
Research, Education and Workforce Development in the United States
Monday, Oct. 17, 2011 | 8:30 a.m. to Noon | Greater Columbus Convention Center, Ballroom 1
The MS&T Plenary Session will feature Subra Suresh, Director, United States National Science Foundation. It will be followed by several prominent
speakers: Carl E. Wieman, Associate Director for Science, White House Office of Science and Technology Policy; Jeffrey Wadsworth, President and
Chief Executive Officer, Battelle Memorial Institute; and Alton D. Romig Jr., Vice President and General Manager of Advanced Development Programs,
Lockheed Martin Aeronautics. A Q&A session with the audience will follow the presentations.
Subra Suresh, Director, United States National
Science Foundation
Title: Innovation Ecosystems: Where Do We
Go from Here?
Abstract: For many decades, materials scientists in
the US have led the world in innovation, creating opSubra Suresh
portunities for the private sector and good jobs. With
global competition reaching a red-hot pitch, we need to consider
the challenges that lie ahead for continued leadership. Two of these
challenges have long-term consequences for the vitality of American enterprise and quality of life. The first challenge is to develop a
world-class scientific workforce. The second is to ease and accelerate the transition from research to new products, processes and
services. Efficient translation capitalizes on the output of fundamental research that serves as the engine of the innovation ecosystem.
Numerous reports have identified fault lines in current STEM education practices and barriers to the commercialization of research
results. The concept of an innovation ecosystem provides a bridge
between these two challenges by describing the interactions among
people, institutions and enterprises from which innovation emerges.
Understanding these links can help us design better practices and
policies to revitalize American innovation.
Carl E. Wieman, Associate Director for
Science, White House Office of Science and
Technology Policy
Title: Taking a Scientific Approach to
Learning and Teaching STEM
Abstract: Guided by experimental tests of theory and
practice, science has advanced rapidly in the past
500 years. Meanwhile, guided primarily by tradition and dogma,
science education has remained largely medieval. Taking a research
approach to teaching STEM subjects is now revealing principles
and practices that achieve much better learning than traditional approaches. The combination of this research approach to instruction
and modern information technology is setting the stage for a major
advance in STEM education, an advance that can provide the relevant and effective science education for all students that is needed
for the 21st century. Wieman will discuss the failures of traditional
educational practices, even as used by very good teachers, and the
successes of some new practices and technology that characterize
a more effective approach, and how these results are consistent
with findings from cognitive science.

Title: Responding to Increasing Energy, Environmental, Health and National Security
Challenges—Investment, Policy and Talent
Issues
Abstract: There is no doubt that world population is
growing significantly and in a geographically uneven manner. Fueled
in part by the Internet, the worldwide expectations for energy usage
and access have rapidly increased. Accompanying new demands
for energy generation are interwoven challenges in environmental, health and national security arenas. These challenges require
increases in US competitiveness with respect to R&D spending,
innovation, education and talent. It is quite clear that the existing
sources of talent cannot meet future US needs. Materials science
and engineering offers one pathway to attract talent into the fields
needed to meet these challenges. Wadsworth will present observations on these topics and on the need to better connect technical
advances with national policy decision making.
Alton D. Romig Jr., Vice President and General
Manager of Advanced Development
Programs, Lockheed Martin Aeronautics
Title: Challenges in Aerospace and Defense
Abstract: Intrinsic to the business of aerospace and
Alton Romig defense is the requirement for fervent and educated
individuals to take up the challenge to lead the US
through current and future technological ages. The rich and varied
tradition of invention is a cornerstone of the “American Dream,” and
while the US is responsible for such 20th century innovations as the
airplane and the personal computer, it is a widely held belief that
our technological superiority will recede in the 21st century. Romig
will discuss the opportunity this technological crisis is creating in
the aerospace and defense sectors, and how Lockheed Martin and
industry across the US is responding. Special emphasis will be on
the unique materials challenges required by a variety of new cuttingedge aircraft platforms.

Reinventing Manufacturing to Answer New
Global Challenges and Market Opportunity
Processing Dielectric Oxides—New
Opportunities and Challenges
Abstract: Tectonic shifts in technology
and the global economy have reshaped
the competitive landscape and driven a
deep transition in the world order of production. For the United States to maintain a high-income economy against rising competitive capabilities globally, we
must thrive on technological and market
discontinuities, exploit game-changing
enabling technologies, turbocharge US
Wince-Smith
innovation and enable more citizens to
participate in entrepreneurship, product ideation, development and production. This requires revolutionary approaches
to design and testing, as well as dynamic manufacturing that
can accommodate extreme variation, product customization,
and serial innovation. In addition, government must establish
policies and investments in research, infrastructure and talent
that attract global investment in US innovation and support
US manufacturing competitiveness globally.
Deborah L. Wince-Smith is the president & CEO of the
Council on Competitiveness, where CEOs, labor leaders and
university presidents are working together to ensure that
Americans prosper in the global economy. Founded in 1986,
this unique business–labor–academia coalition recommends
actionable public policy solutions to make America more
competitive in the global marketplace.
As president of the Council on Competitiveness, WinceSmith spearheaded the 2004 National Innovation Initiative,
which played a pivotal role in shaping the bipartisan America
COMPETES Act.
Wince-Smith is the president of the newly formed Global
Federation of Competitiveness Councils, the first global network devoted exclusively to the exchange of knowledge and
practice related to competitiveness policies and strategies,
and the first global, public–private mechanism to promote
global economic growth through collaboration in innovation.
During her 17-year tenure in the federal government,
Wince-Smith held leading positions in the areas of science,
technology policy and international economic affairs. As a
program director for the National Science Foundation, she
managed US research programs between Eastern European
countries and US universities. She served as the nation’s first
assistant secretary of commerce for technology policy in the
administration of George H.W. Bush, and she was the first
assistant director of international affairs and competitiveness
in the White House Office of Science and Technology Policy.
She is a graduate of Vassar College and King’s College at
the University of Cambridge, United Kingdom.

Abstract: Given the history and philosophy inspired by the Friedberg Memorial
Lecture Series, the aim will be to share
contemporary issues in processing
dielectric materials, with some surprising
new insights.
The challenges of cofiring in reducing
atmospheres and interfacial interactions
between nickel and BaTiO3 will be considered. The nature of thermochemical
Randall
interactions and the merits of fast and
multistage sintering processes will be discussed.
There have been efforts to lower sintering temperatures
to permit microwave dielectrics to be cofired into multilayers
with silver and copper electrodes. Although surprising, multilayer structures such as scheelite and lyonsite can be cofired
at approximately 550°C with aluminum inner electrodes.
Most ferroelectric ceramics research has focused on processing materials with high resistivity and minimized pointdefect concentrations. Here the opposite is considered, and
extremely high concentrations of oxygen vacancy defects are
introduced that, through electronic compensation, provide
electronic concentrations. Concentrations are considered
in and around the Mott transition that change the electrical
conductivity from semiconducting to metallic. There is interesting coupling between the spontaneous polarization of the
ferroelectric and the thermoelectric characteristics, which
is controlled by the conduction at this crossover point. The
results in tungsten bronze materials, such as (Sr,Ba)Nb2O6-δ,
also indicate very high performance.
Clive A. Randall is professor of materials science and
engineering and director of the Center for Dielectric Studies at
Pennsylvania State University.
Randall earned his BSc in physics from the University of
East Anglia and his PhD in experimental physics from the
University of Essex, both in the United Kingdom. He has
authored or coauthored more than 280 technical papers and
holds 13 patents (three pending) in the field of electroceramics. He was elected Academician of the World Academy of
Ceramics in 2006. In 2007, he and his colleagues received the
R&D 100 Award for their Integrated Fiber Alignment Package.
Randall is a member of the ACerS Electronics Division, is a
Fellow of the Society, and has been honored with the Fulrath
Award and the Spriggs Phase Equilibria Award. He has been
an associate editor of the Journal of the American Ceramic
Society since 1993.

Lessons Learned After 40 Years of Sintering
Technical Ceramics
Abstract: In 1969, I began my journey
into the world of ceramic process as an
undergraduate at Alfred University. In the
intervening years I’ve been involved with
sintering ceramics as diverse as dolomite refractories and transparent Y3Al5O12
for laser gain media. Since 1980, my
research group at Pennsylvania State
University has focused on developing
unique and improved technical ceramics
Messing
by applying and developing core microstructure–property concepts. I will present personal vignettes
of research successes that demonstrate how the sintering of
technical ceramics has evolved from an empirical discipline to
one that is more scientifically principled and key for developing new technical ceramics. Specific processes and materials
to be discussed include room-temperature sintering of salt
(NaCl), templated grain growth of textured ceramics, perfect
processing of transparent ceramics for laser gain media and
management of stresses in cofired ceramics. Finally, I use the
lessons learned to set the stage for future research needs in
the field of sintering.
Gary L. Messing is distinguished professor of ceramic science and engineering and head of the Department of Materials
Science and Engineering at Penn State.
Messing earned his BS degree in ceramic engineering from
the New York State College of Ceramics at Alfred University
and his PhD in materials science and engineering from the
University of Florida.
He has published more than 300 books and papers and has
been a coorganizer of the International Ceramic Processing
Science Conference since 1986. He was coeditor of the
Journal of the American Ceramic Society from 1993 to 1998,
editor-in-chief of Ceramics International (2001–2009) and principal editor of Materials Letters (2003–2009). In 2009, he was
appointed editor-in-chief of the Journal of Materials Research.
The American Ceramic Society has recognized his achievements with several awards, including the Richard M. Fulrath
Award, the Robert M. Sosman Memorial Lecture Award, the
John Jeppson Award and the Outstanding Educator Award
from the Ceramic Educational Council. He is an ACerS Fellow
and served as the Society’s president in 2005. He is a member of the World Academy of Ceramics, was named to the

Interface-Structure Dependent Microstructural
Evolution in Ceramics
Abstract: Recently, we suggested the
principles of microstructural evolution in
ceramics with respect to the interface
structure, either faceted or rough. The
principles are based on the coupling
effect between the maximum driving
force for grain growth and the critical
driving force for appreciable growth.
Various types of nonstationary grain
growth in terms of a change in relative
Kang
grain-size distribution according to
annealing time are predicted when the interfaces are either
fully or partially faceted. This presentation provides our theoretical as well as experimental results pertaining to microstructural evolution and control in single-phase as well as
two-phase systems for different interface structures. The
effect of the interface structure on densification during solidstate sintering also is presented. The solid-state conversion of
single crystals from polycrystalline compacts also is demonstrated as an exemplary application of the principles.
Suk-Joong L. Kang is distinguished professor in the
Department of Materials Science and Engineering and the
director of the Center for NanoInterface Technology at the
Korea Advanced Institute of Science and Technology. He
earned his BS in metallurgy from Seoul National University in
1973, MS in materials science and engineering from KAIST
in 1975, Dr-Ing in materials from the École Centrale Paris in
1980 and his Dr. d’état in physical science from the University
of Paris VI in 1985. He joined KAIST in 1980 and also served
several institutions as a visiting professor or researcher, including the Max Plank Institute in Stuttgart, Germany, Samsung
Electromechanics, the University of New South Wales,
Australia, and at the University of Tokyo.
Kang has published more than 230 papers on sintering and
microstructure evolution in ceramics and metals. He developed
the pore-filling theory of liquid-phase sintering and demonstrated diffusion-induced interface migration and recrystallization in alumina and perovskites. During the past 12 years
he has made significant contributions to the understanding
of microstructure evolution by structural transition and defect
formation at interfaces. Kang is the author of the text, Sintering:
Densification, Grain Growth and Microstructure, published in
2005.
Kang is a Fellow of The American Ceramic Society and is
a member of the World Academy of Ceramics, the Korean

deciphering the discipline
The future of materials
just graduated … Now
what?
Thomas Burton
Guest columnist
conferences and working with a professional society.
The first time I really felt like I was
part of the materials field was when I
attended the Materials Science and
Technology Conference in 2008—my
first MS&T. Here was an open platter
of anything and everything materials
related, and my head spun with all the
possibilities before me.
This point of becoming part of your
professional community is an important
one. Professionals see their work as taking
place on a stage larger than just the lab
and, thus, work hard to stay up-to-date
in current affairs. For active professionals
and undergrads this means reading journals, magazines and websites. Students
have the wonderful opportunity of joining
Material Advantage for little cost, giving
them access to a wealth of professionals,
news and prospects. Professional societies
like ACerS can showcase the skills and
experience of students and young professionals on a larger scale, for example,
through the ACerS online listing of résumés and job postings where students and
hiring companies can meet easily.
The last important lesson that all
college students and young professionals need to learn is that they are now
in a world of self-initiation. They say
that college is what you make of it. The
same is true for everything thereafter,
because from now on you are your own
advocate and secretary.
Having a goal in mind is the difference between your path feeling like
drudgery or more like a path you belong
on: the path of a professional. This
goal has to motivate you—it has to
inspire you. To that end, my goal is to
eventually work for Advanced Research
Projects Agency–Energy. Time will tell
whether I achieve it, but my goal keeps
me motivated through the projects,
papers and forms.
In conclusion, there are many factors
that define a professional engineer. Two
important qualities are initiative and
community involvement. Students and
transitioning professionals have access
to resources that help them build these
areas as they start their careers. Take
advantage of them and help all of us
continue the bright future of materials.
Material Advantage and
Keramos chapters will find a wealth of
information at PCSA’s web resources.
the next few months the website will
add a find-a-graduate-school searchable
database to help match students with
faculty and graduate schools by research
interests.

PCSA website or search for the ACerS
President’s Council of Student Advisors

Attending college while my mother
was a guidance counselor for a high
school near my hometown was a challenge. Whenever I was home for break,
I was constantly bombarded with
information and questions. Sound bites
of statistics, college preparedness and
maturity were folded into conversations
as I filled her in on the details of my
new life. As I look back, I am in awe
at how much I have gotten out of each
pearl of wisdom she doled out. The
most important ones put me on a path
to becoming a professional in my field,
but, ultimately, it was up to me to make
it happen.
A quick Google images search for
“professional” conjures many photos
of people in business suits. However, I
think many of us will agree that what
is under the expensive attire is much
more important for our definition of an
engineering professional.
Professional engineers are not formed
solely from their experiences outside of
college, as many undergraduates think.
Much of the knowledge and drive to be
an engineer is learned in the classroom.
Often, the experiences that transition us
from student to professional are the extra
hours put in to such things as attending
