Science and Technology of Advanced Materials
Science and Technology of Advanced Materials iopscience.org/stam Open access journal Supported by Science and Technology of Advanced Materials How to submit your research Science and Technology of Advanced Materials (STAM) is one of the highest rated gold open access journals in materials science. After peer review and acceptance, authors will be asked to pay an article publication charge (APC) of ¥135000/US$1600/€1260/£1050. Once published, articles are freely available to read. To celebrate our 15th volume, during 2014, articles identified by the Editorial Board as being of particularly high quality will have their article publication charge sponsored by the National Institute of Materials Science (NIMS) and the Swiss Federal Laboratories for Materials Science and Technology (Empa). Plan Consider the best way to structure your article before you start. Science and Technology of Advanced Materials does not have a template, but asks that you submit your manuscript in single-column format. Choose a title that best serves your needs – an eye-catching one to attract as many readers as possible, or a descriptive one to engage readers with a specific interest in your area. Give some thought to your abstract. It should very concisely describe the content of your article, and encourage readers to view the entire article. No jargon or undefined abbreviations should be used. Writing Be clear and concise. Consider the readership of the journal, bearing in mind the knowledge expected of that audience. All content of your article should be relevant to your main scientific result. Editing Have a look through previously published articles for examples of article formatting, particularly with respect to order, referencing style and capitalization. Once the draft is ready to be submitted to the journal, carry out one final spelling and grammar check before submission. Submissions STAM publishes reviews and regular research articles. All articles must be written in English and pass the peerreview process. STAM operation is managed by the Editorial Office, which should receive all related enquiries.

In human terms the journal is junior-high-school age – young and having experienced many changes over the last five years. STAM was established in 2000 with the aim of being an international journal by publishing timely papers on scientific advances in materials science and engineering. The publication of the journal saw a turning point in 2005 when the management of the journal was transferred to the National Institute for Materials Science (NIMS) in Tsukuba from The University of Tokyo. Notably, STAM became an open access journal in 2008 and adopted an author-friendly Creative Commons non-commercial licence (CC-BY-NC). This new publication platform was changed in 2013 by introducing the article processing charge (APC), although downloading articles is still free of charge and the licence was changed again in 2014 to a less-restrictive CC-BY. On 27 January 2014, Empa, the Swiss Federal Laboratories for Materials Science and Technology, and NIMS signed a five-year collaborative agreement on co-publishing STAM. Both Empa and NIMS are the leading materials science research institutes in their respective countries with histories spanning more than half a century. Starting from 2008 several measures have been introduced to improve the quality, variety and visibility of STAM articles, and to speed up the publication process. Most importantly, STAM has invested in proactive dissemination and distribution of information about the journal to build readership. For example, selected articles are promoted via press releases and free distribution of printed copies at major scientific events. The topical coverage has been widened from traditional metals and ceramics to biomaterials, green technology, nano-devices and other frontier areas. As a result, the impact factor of STAM saw a continuous rise from 1.267 in 2008 to the most recent value of 3.752 in 2012. STAM has become one of the major prominent materials science journals in the world and is currently ranked 35th among 239 journals worldwide in the category of “Materials Science & Multidisciplinary” by Thomson Reuters. Needless to say, STAM is the leading materials science journal published in Japan. These achievements are a result of steadfast and multi-faceted efforts by STAM editors, referees and authors, for which I am sincerely grateful. Yet there is still a lot more to be done and I welcome submissions of new findings, as well as suggestions and ideas on how to steer the management of the journal in the future. This collection features a selection of 15 outstanding articles published in STAM during the last 15 years. Although we strived to be objective and used multiple criteria in selecting these from hundreds of papers published in STAM, a number of worthy candidates had to be excluded. I hope that we will be able to acknowledge the omitted articles in other STAM publications. iopscience.org/stam/15th-anniversary 3 Science and Technology of Advanced Materials Contents Organic materials Challenges and breakthroughs in recent research on self-assembly 6 Katsuhiko Ariga, Jonathan P Hill, Michael V Lee, Ajayan Vinu, Richard Charvet and Somobrata Acharya Technological advances in electrospinning of nanofibers 7 Wee-Eong Teo, Ryuji Inai and Seeram Ramakrishna Biomaterials Recent research and development in titanium alloys for biomedical applications and healthcare goods 8 Mitsuo Niinomi Porous hydroxyapatite for artificial bone applications 9 I Sopyan, M Mel, S Ramesh and K A Khalid Bioinspired phospholipid polymer biomaterials for making high performance artificial organs 9 K Ishihara Electronics Silicon-based oxynitride and nitride phosphors for white LEDs—A review 10 Rong-Jun Xie and Naoto Hirosaki Present status of amorphous In–Ga–Zn–O thin-film transistors 11 Toshio Kamiya, Kenji Nomura and Hideo Hosono Solid State Ionics: from Michael Faraday to green energy—the European dimension Klaus Funke 4 iopscience.org/stam/15th-anniversary 12 Science and Technology of Advanced Materials Environment Nitrogen-doped titanium dioxide photocatalysts for visible response prepared by using organic compounds 13 Yoshio Nosaka, Masami Matsushita, Junichi Nishino and Atsuko Y Nosaka The effect of nanocrystalline magnetite size on arsenic removal 14 J T Mayo, C Yavuz, S Yean, L Cong, H Shipley, W Yu, J Falkner, A Kan, M Tomson and V L Colvin Recent progress in mesoporous titania materials: adjusting morphology for innovative applications 15 Juan L Vivero-Escoto, Ya-Dong Chiang, Kevin C-W Wu and Yusuke Yamauchi Dispersion and surface functionalization of oxide nanoparticles for transparent photocatalytic and UV-protecting coatings and sunscreens 16 Bertrand Faure, German Salazar-Alvarez, Anwar Ahniyaz, Irune Villaluenga, Gemma Berriozabal, Yolanda R De Miguel and Lennart Bergström Ceramics Hydrothermal growth of ZnO nanostructures 17 Sunandan Baruah and Joydeep Dutta Point defects in ZnO: an approach from first principles 18 Fumiyasu Oba, Minseok Choi, Atsushi Togo and Isao Tanaka Metals Progress in thermomechanical control of steel plates and their commercialization 19 Kiyoshi Nishioka and Kazutoshi Ichikawa iopscience.org/stam/15th-anniversary 5 Science and Technology of Advanced Materials Organic materials EDITOR’S CHOICE Challenges and breakthroughs in recent research on self-assembly Katsuhiko Ariga, Jonathan P Hill, Michael V Lee, Ajayan Vinu, Richard Charvet and Somobrata Acharya 2008 Sci. Technol. Adv. Mater. 9 014109 Katsuhiko Ariga Controlled production of nanometre-scale objects is a key issue of the current science and technology. “Top-down” fabrication techniques, such as lithography, are limited in the size of resulting structures and in the range of suitable bulk materials, urging development of alternative (“bottom-up”) approaches based on self-assembly of individual molecules. This review covers a wide variety of self-assembly processes and introduces recent breakthroughs in (i) types of self-assembly in bulk media, (ii) types of components for self-assembly in bulk media and (iii) self-assembly at interfaces. It summarizes them according to the length scale as follows. At the smallest scale, structural control over molecular arrays yields nano-objects, whose properties are mostly affected by molecular attributes such as morphology and arrangement of functional groups. Yet for larger, micron-sized objects, optimization of hierarchical processes is becoming more important than molecular structure in creating novel materials. Self-assembly processes are also efficient in fabrication of macroscopic objects with a nanostructure. As those processes involve individual molecules, their use in the preparation of bulk materials needs interactive connections. For example, some techniques, such as dynamic manipulation of molecules at the air–water interface, can bridge between the molecular and macroscopic worlds. Bulk coordination polymers, porous crystals, liquid crystals and gels can be produced via self-assembly, but their structural motifs are rather simple. In contrast, evolution created much more sophisticated objects starting (A) Structure of cerasome, a novel class of from individual molecules. We have to learn bilayered organic-inorganic hybrids, and ways to build complex hierarchic structures from (B) cerasome self-assembly. biological examples in order to construct multifunctional materials via self-assembly. Current bottom-up techniques are insufficient for this purpose and should be complimented with top-down methods. With 46,597 downloads (IOPscience) and 449 citations (Web of Science, as of May 2014) this is the most popular STAM article. The 127 well designed figures make it easy reading despite its 96-page volume. 6 iopscience.org/stam/15th-anniversary Science and Technology of Advanced Materials organic Technological advances in electrospinning of nanofibers Wee-Eong Teo, Ryuji Inai and Seeram Ramakrishna 2011 Sci.

Technol. Adv. Mater. 4 445 Titanium-based materials are widely used in medical applications such as artificial limbs, dental products, wheelchairs and implants for healing of bone fractures. However, all those applications are dominated by pure Ti and Ti-6Al-4V alloy, which were previously developed for structural elements in aerospace industry. This review discusses a wide range of other Ti alloys with a focus not only on mechanical properties but also biocompatibility.

Technol. Adv. Mater. 8 116 I Sopyan This paper discusses preparation techniques of porous hydroxyapatite (HA) and its biomedical applications, including bone tissue regeneration, cell proliferation and drug delivery. HA has been applied as filling material for bone defects and augmentation, artificial bone graft material and prosthesis surgery. Its high surface area leads to excellent osteoconductivity and resorbability providing fast bone ingrowth. Porous HA can be produced by several methods including conversion of natural bones, ceramic foaming technique, the polymeric sponge method, gel casting of foams, starch consolidation, microwave processing, slip casting and electrophoretic deposition.

Bioinspired phospholipid polymer biomaterials for making high performance artificial organs K Ishihara K Ishihara 2000 Sci. Technol. Adv. Mater. 1 131 This review demonstrates the importance of molecular structure in designing polymeric biomaterials. In particular, introduction of a certain phospholipid polar group (MPC group) to the side chain of a polymer inhibits adsorption of blood and proteins to that polymer, rendering it biocompatible – blood clotting is suppressed and the coagulation time gradually increases with the MPC content in the polymer. In practical terms, coating of commercial polymers with MPC is shown to improve the biocompatibility of vascular prostheses, cellulose membranes, glucose sensors, artificial organs, drug delivery and other systems introduced into the human body.

Technol. Adv. Mater. 8 588 Rong-Jun Xie Naoto Hirosaki Silicon-based nitrides and oxynitrides doped with rare-earth elements are two recently developed classes of inorganic phosphors with promising applications in solid-state lighting and displays. This review focuses on their preparation, crystal structure, luminescence and applications in light-emitting diodes (LEDs). The crystal structures of silicon-based (oxy)nitrides consist of networks of crosslinked SiN4 tetrahedra. They are characterized by strong and tunable crystal-field splitting and nephelauxetic effect, which lower the excited states of doped rare-earth ions (mainly Eu2+, Ce3+ and Yb2+) and broaden them into bands that may extend from the UV to visible range. In practical terms this means those phosphors can be excited by a variety of light sources, their emission color can be tuned from blue to red, and mixing two or more such phosphors may result in a white light with adjustable correlated colour temperature. White light can even be produced with one yellow-green phosphor, such as α-sialon:Eu2+, when its emission is combined with the pumping light of a blue LED. Besides favourable spectral properties silicon (oxy)nitride phosphors have a high chromatic stability and quantum efficiency of luminescence (>90%), which makes them preferred materials for conversion of narrowband LEDs into compact, efficient, stable and durable white-light sources for indicators, cellular phones, liquid crystal displays and general lighting applications.

Science and Technology of Advanced Materials electronics EDITOR’S CHOICE Present status of amorphous In–Ga–Zn–O thin-film transistors Toshio Kamiya, Kenji Nomura and Hideo Hosono 2010 Sci. Technol. Adv. Mater. 11 044305 Toshio Kamiya Hideo Hosono Amorphous oxide semiconductors, particularly the quaternary In-Ga-Zn-O alloy known as a-IGZO, have a superior combination of physical and technological properties as compared with silicon and organic materials. Similar to its competitors, a-IGZO can be fabricated at temperatures below 400 °C on glass or flexible plastic substrates. Yet it offers much higher carrier mobility than a-Si and organic semiconductors, as well as higher stability and uniformity of properties than a-Si and poly-Si, which is crucial for display applications. Consequently, it is expected that thin-film transistors (TFTs) with a-IGZO channels will dominate various types of next-generation electronic devices, such as flatpanel, 3D, flexible and transparent displays. This review covers both fundamental and technological issues of amorphous oxides, with a focus on a-IGZO, such as electronic and optical properties; their uniformity over large areas, long-term stability and degradation mechanisms; operation speed; transistor characteristics; and fabrication processes. IGZO has been actively studied since the early 1990s, with the first IGZO TFT fabricated in 2004 and the first IGZO-based display revealed in 2005. The main IGZO fabrication technique, RF/DC magnetron sputtering, is compatible with large areas. By 2010 it supported 8-generation displays with external sizes exceeding 2 × 2 m, and 6-generation 32” and 37” displays had already been fabricated. Electronic properties of a-IGZO have been extensively characterized and theoretical modelling of operational devices is already possible. The relatively high field-effect mobility of charge carriers in a-IGZO (~20 cm2 V–1 s–1) supports refresh rates exceeding 100 Hz in large-area displays. The main degradation mechanisms of a-IGZO TFTs are back-channel effects, creation of traps at the interfaces and in the gate insulator, as well as creation of donor states and other defects by the Joule heating during operation or by annealing during fabrication of TFTs. They can be alleviated by the addition of dense passivation layers to the TFTs.

Technol. Adv. Mater. 6 143 Yoshio Nosaka One of the major problems of photocatalysis is to shift the optical response of TiO2, the most popular photocatalytic material, from the UV to the visible range, making it sensitive to sunlight and conventional light sources. Nosaka et al. achieved this by nitrogen doping of nine commercial TiO2 powders using urea, guanidine carbonate or guanidine hydrochloride. After soaking the powders in an aqueous solution of a dopant, they were dried and annealed at 300–600 °C. The photocatalytic activity was the highest when using guanine carbonate and annealing temperatures of 350–400 °C. It increased significantly with doping, but only when nitrogen substituted for oxygen in the TiO2 lattice, as revealed by the analysis of Ti bonding through X-ray photoelectron spectra.

Technol. Adv. Mater. 8 71 V L Colvin Removal of arsenic (As) contamination from drinking water is a major problem around the world. One solution is to adsorb As using a magnetic powder (magnetite, Fe3O4) and precipitate the powder with a magnetic separator. This article reveals the dramatic effect of the Fe3O4 particle size d on the As removal – when d was decreased from 300 to 12 nm the As adsorption increased ~200 times. This effect is too strong to be explained by a surface area increase and suggests different As adsorption mechanisms for bulk and nanomaterials. Fe3O4 nanoparticles with adsorbed arsenic ions can be removed from water using a magnetic separator.

Technol. Adv. Mater. 13 013003 This review describes recent developments in mesoporous titania (TiO2) materials, particularly in the synthesis, morphology control and applications in photocatalysis, photovoltaics, sensing and biomedical fields. These materials are attractive because of their high surface area, controlled morphology, porous structure, biocompatibility and semiconducting behaviour. In addition, mesoporous titania nanoparticles offer fast mass transport, strong adhesion to substrates and good dispersion in solution, which are beneficial for catalysis, particle separation, medical and optical applications.

Technol. Adv. Mater. 10 013001 Joydeep Dutta Nanostructured ZnO is an attractive technological material for a wide variety of applications including surface acoustic wave filters, photonic crystals, photodetectors, light-emitting diodes, gas sensors, optical modulator, waveguides, solar cells, photocalysts and antibacterial agents. Among its different production methods, hydrothermal routes are favoured for their simplicity and environment-friendly conditions. This review focuses on the dependence of ZnO morphology on the growth conditions and also discusses ZnO doping during the growth. An aqueous solution of zinc nitrate and hexamine is the most common hydrothermal medium for the growth of ZnO, though other solvents such as alcohol have also been tried. The synthesis is typically conducted at 60–200 °C with temperatures above 100 °C achieved using an autoclave. Reaction time typically varies from several hours to days and even weeks, though it may be shortened to minutes by the application of microwave radiation. In contrast to solution-based routes, gas-phase ZnO synthesis is conducted at 500–1500 °C through a variety of techniques such as vapor phase transport, physical vapor deposition, chemical vapor deposition, metal-organic chemical vapor deposition, thermal oxidation of Zn and microwave-assisted thermal decomposition. The most common ZnO morphologies achieved via hydrothermal routes are isometric particles, plates and hexagonal rods. Plates are usually stacked or arranged into flowerlike shapes, whereas rods form parallel bundles, tetrapods, hedgehog-like stars or aligned forests on a flat substrates, and their tips may be sharpened in a pencil-like fashion. The dopants that have been introduced during the hydrothermal growth of ZnO include Al, Co, Cr, Cu, Ga, Mn, Sb and Sn. Their range is limited by reactivity with water during the synthesis; for example, In doping is hindered by the formation of In(OH)3 phase. Low-temperature (~60 °C) hydrothermal growth of ZnO nanorods can be shortened from hours or days to minutes by the use of microwave radiation.

Technol. Adv. Mater. 12 034302 Fumiyasu Oba This review covers recent first-principle studies of point defects in ZnO, with an accent on native defects that affect the electrical conductivity, such as Zn and O vacancies, interstitials and anticites. The predicted properties of defects, such as formation energies, donor and acceptor levels, optical transition energies, migration energies, and atomic and electronic structure, strongly depend on the calculation method, particularly on the simulation model, approximation to exchange correlation and the post-processing applied to compensate for the shortcomings of the approximation and model.

Technol. Adv. Mater. 13 023001 Thermomechanical control processes (TMCP) were developed in the 1930s to improve the strength and toughness of steel, while allowing control of the microstructure, phase transformation and rolling. Nowadays TMCP steels are widely used in shipbuilding, offshore structures, building construction, bridges, pipelines, penstocks and cryogenic tanks. This review describes metallurgical aspects of the microalloying of steel, such as addition of Nb, and discusses advantages of TMCP such as improved weldability. Other topics include the TMCP history, equipment and technologies, distortions in steel plates and theoretical modelling.
