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 individual companies cannot go it American Ceramic Society Bulletin, Vol. 90, No. 7 3 news & trends 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.

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 American Ceramic Society Bulletin, Vol. 90, No. 7 ‘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. In the press conference, John American Ceramic Society Bulletin, Vol. 90, No. 7 (Credit: NSF.) 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 5 acers spotlight Welcome to our newest Corporate Members ACerS recognizes organizations that joined the society as Corporate Members in the past few months.

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.

In the United States that adds up to $2–4 trillion per decade, which equates to rebuilding Hurricane Katrina-scale infrastructure three or four times. An online article published by Environmental Protection (www. eponline.com) reports on a new protective coating based on chemically bonded phosphate ceramics. CBPCs are a class of materials that were developed at Argonne National Lab and Battelle to stabilize mercury-containing DOE wastes. They are synthesized via an acid-base reaction between magnesium oxide and a monopotassium phosphate solution (KH2PO2), which yields MgKPO4·6H2O, a hard, dense material. A Raleigh-Durham Research Triangle company, EonCoat, has picked up the technology and developed it into a corrosion-resistant coating. The EonCoat product is a spray-on two-component system that reacts with the substrate in a mildly exothermic reaction, that “creates an alloyed metal surface rather than a layer that sits on top of the substrate,” the EP story says. The coatings are able to Chemically bonded phosphate ceramic coating accommodate flexure up to 19 on a metal substrate (black region). percent.

To minimize toxicity testing on animals, the European Chemicals Agency recommends grouping of substances and development of quantitative mathematical approaches to relating chemical structure to measured properties or activities. A paper in the July/August issue of the International Journal of Applied 12 Ceramic Technology describes the use of the Rietveld method of X-ray diffraction for grouping differing pigment formulations together. (The Rietveld method provides quantitative phase analysis.) Powder XRD also identified the crystalline phases present. (See De La Torre, et al., doi: 10:1111/j.17447402.2010.02528.x) The Spanish group studied three pigments, two black and one brown. The black formulations were commercially available pigments comprised of Fe2O3 and Cr2O3. The brown composition was laboratory prepared and also was mostly Fe2O3 and Cr2O3, but with reduced Cr2O3 to accommodate other oxides in the formulation. Using powder XRD, the black pigments were found to be single phase, and the brown pigment was more complex, consisting of two phases with corundum structure, a magnesium chromate spinel phase and a small but measurable amorphous phase. The researchers concluded that the Rietveld method is a valid approach to quantitative mineralogical analysis of pigments and an effective means for grouping pigments, and, thus, useful to “narrow down the number of toxicity tests required to fulfill the REACH legislation.” Grouping of substances could have a huge impact on the costs (monetary and biological) associated with animal testing.

During recharging, the lithium oxides separate into lithium and oxygen and the process can begin again. (Credit: Mitchell, Gallant, and Shao-Horn; MIT) 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.) More energy density in lithium-air batteries with carbon nanofiber carpet electrode SEM image shows particles of lithium peroxide forming as small dots on the sides of carbon nanofibers (left) and becoming larger toroidal shapes as the battery discharges (right). another graduate student and coauthor, 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,” doi: 10.1039/C1EE01496J).

The group has created lead titanate and lead zirconate titanate American Ceramic Society Bulletin, Vol. 90, No. 7 (Credit: IBM Research) 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 and AgInSbTe compounds. Unidirectional amorphicity reduces entropy structures on polyimide, glass and silicon substrates. The TCNL work is described in recent paper in Advanced Materials (doi:10.1002/adma.201101991). In the paper, investigators report producing wires approximately 30 nanometers wide and spheres with diameters of approximately 10 nanometers were fabricated at densities exceeding 200 gigabytes per square inch, a record for this perovskite-type ferroelectric material. According to a GT news release, the group hopes their work might lead to high-density, low-cost production of complex ferroelectric structures, such as energy-harvesting arrays, sensors and actuators in nanoelectromechanical A just-published paper in Nature Nanotechnology addresses PCMM technology by considering the nature of the amorphous state (see Simpson, et al., doi: 10.1038/nnano.2011.96). The aim was to reduce the energy needed to “switch” the material by limiting the movement of atoms to a single dimension, greatly reducing entropy. By aligning the c-axis of a hexagonal Sb2Te3 layer in the <111> direction of a cubic-GeTe layer in a superlattice structure, germanium atoms can switch sites at the interface of the layers. The abstract says they have demonstrated “interfacial phase-change memory data storage devices with reduced switching energies, improved write–erase cycle lifetimes and faster switching speeds.” n (Credit: Suenne Kim, Georgia Tech.)

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.” Awards Banquet The winners of the Society’s 2011 awards, including the new Distinguished Life Members and the new Class of Fellows, will be honored at the ACerS Annual Awards and Honors Banquet, Monday, Oct. 17, 2011, 7:30 p.m. – 9:30 p.m., in Columbus, Ohio.

American Ceramic Society Bulletin, Vol. 90, No. 7 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.

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 synthesis The earliest efforts to use these materials for medical applications took place 24 by P.R. Miller A.Ovsianikov A.Koroleva S.D. Gittard B.N. Chichkov R.J. Narayan 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. Catauro et al.5 showed that zircoAmerican Ceramic Society Bulletin, Vol. 90, No. 7 An introduction to hybrid ceramic materials and zirconia sol–gels 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 als from a mixture of (b) (a) poly(epsilon-caprolactone), yttrium chloride, zirconium propoxide, chloroform and water. They then loaded indomethacin or ketoprofen into the zirconium oxide sol–gel microspheres using a single-step, sol–gel approach. As with the ampicillin, they looked at the release of these anti-inflammatory agents in simulated body Fig. 1.

Salehi and M.H. Fathi, Ceramics International, Vol. 36.) nium oxide hybrid material can be used for drug delivery. Zirconium oxidepoly(epsilon-caprolactone) was synthesized via a sol–gel approach, in which hydrogen bonding between Zr–OH groups and carboxylic acid groups provided structural cohesion. The average domain size was 19 nanometers. They 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 body fluid for 21 days and found a layer of hydroxyapatite had formed on the surface. Catauro et al.6 also made hybrid class I materials (see below) containing poly(epsilon-caprolactone) and zirconia–yttria. Again using a sol–gel approach, they prepared these materi- ent 0.6–1.1-micrometer-thick films demonstrated antibacterial activity against Escherichia coli and Staphylococcus aureus in agar diffusion and liquid medium assays. 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. 25 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 26 nanometer). In 2PP, a femtosecond laser beam is tightly focused within a near-infrared-lighttransparent photosensitive material, causing a nearly simultaneous absorption of two near-infrared photons Fig. 2.

They found that 88 weight percent zirconium oxide and 12 weight percent poly(epsilon-caprolactone) exhibited appropriate biological and mechanical properties for use in bone tissue engineering. Salehi and Fathi8 used a sol–gel approach to prepare HA/30 weight percent yttria-stabilized zirconia nanopowder. They doped zirconia with 0.8 mole percent yttria by reacting zirconium alkoxides with yttrium acetate. These samples contained 20–30-nanometer spherical YSZ particles and irregularly shaped 40–80-nanometer HA particles, with the YSZ nanoparticles homogeneously distributed among the HA nanoparticles (Fig. 1). The nanoparticles clustered to form 500-nanometer to 8-micrometer aggregates. They found that the yttrium segregation at grain boundaries provided an obstacle to YSZ particle growth and that the calcium– zirconium ion exchange increases the HA unit cell volume. Calcining the HA–YSZ nanopowder at 950°C produced a material with larger grain sizes and higher crystallinity. According to Salehi and Fathi, an advantage of this processing is the homogeneous nature of sol–gel-prepared nanopowders.

Medical structures Recent efforts have focused on using 2PP to fabricate medically relevant structures out of zirconium oxide hybrid 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 LC6500, fluorescein and rhodamine 6G). Fluorescence microscopy was used for imaging the internal structural features. Schizas et al.23 used 2PP to go as far as creating micro check valves out of a (Credit: Miller, et al.)

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. Figure 4(a) shows a scanning electron micrograph of a portion of a tissueengineering scaffold. The hexagonal scaffold is composed of an array of hollow cylinders (radius = 50 micrometers), and each side of the scaffold con- (Credit: Miller, et al.) (Credit: Miller, et al.)

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 American Ceramic Society Bulletin, Vol. 90, No. 7 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. About the authors P.R. Miller, S.D. Gittard and R.J.

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. 30 (Provided by Shaojie Wang) I 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.

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. American Ceramic Society Bulletin, Vol. 90, No. 7 Students in Kazuyuki Hirao’s research group. Masahiro Shimizu, left, Stone and Masaaki Eida in the KU’s Katsura Campus laser lab. “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 31 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.” For more information about the IMI-NFG’s international research opportunities, see http://www.lehigh.edu/imi and click on “Opportunities,” email [email protected] or call (610) 758-1112. n (Credit: Yasuhiko Shimotsuma) by Amy White Masaaki Sakakura, left, an assistant professor at Kyoto University’s Innovative Collaboration Center, points at the light emission from plasma that forms at the focal point, with Adam Stone, right, in the lab of Kazuyuki Hirao at the university’s Katsura Campus. Sakakura helped Stone learn to use the laser equipment. 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. American Ceramic Society Bulletin, Vol. 90, No. 7 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.

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.” For more information about IMINFG’s international research opportunities, see www.lehigh.edu/imi and click on “Opportunities,” email imi@ lehigh.edu or call 610-758-1112. n The NSF also funds several other International Materials Institutes: • University of California, Santa Barbara: International Center for Materials Research, www.icmr.ucsb.edu • University of California System: International Institute on Complex Adaptive Matter (I2CAM), www.i2cam.org • Northwestern University: International Materials Institute for Solar Energy and Environment, www.imisee.net • Texas Engineering Experiment Station: International Institute for Multifunctional Materials for Energy Conversion, http://iimec. tamu.edu 33 by Tom Adams Multiple-gate acoustic imaging of an advanced ceramic Acoustic microimaging and ultrasonic testing systems provide a nondestructive method to reveal and analyze hidden defects. T he ultrasound used 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 American Ceramic Society Bulletin, Vol. 90, No. 7 (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, American Ceramic Society Bulletin, Vol. 90, No. 7 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.)

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. Carl Wieman 38 Jeff Wadsworth Jeffrey Wadsworth, President and CEO, Battelle Memorial Institute 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.

Randall 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. 42 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.

Messing 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.

American Ceramic Society Bulletin, Vol. 90, No. 7 Basic Science Division’s Robert B. Sosman Award and Lecture Wednesday,Oct.19,2011•1:00p.m. Greater Columbus Convention Center, Room C113/114 Suk-Joong L. Kang 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.

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 Academy of Science and Technology and the National Academy of Engineering in Korea. 43 ® Richard M.

Cleveland Ave, Suite 210 Westerville, OH 43082 55 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. Visit the PCSA website at: www. ceramics.org/pcsa. On ceramics.org On facebook.com ence activities and share professional resources. Discussions about interesting company visits and helpful job resources are invited, so be sure to check out the page. Postings are updated frequently, providing information about conference hotels, competitions and scholarships. Find the Facebook link on our PCSA website or search for the ACerS President’s Council of Student Advisors page. 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 Material Advantage and Keramos web resources from PCSA Check out the PCSA website for information about becoming a delegate and links to conference information.
