An undergraduate program is under consideration for the future. Ceram building first commercial-scale flash sintering kiln? The still-young technique of flash sintering, in theory, could deliver a broad revolution in the preparation of ceramic materials. It appears the theory soon will be put to a significant manufacturing test by a UK-based company, Ceram. The new sintering method could be one of the most profound and disrupting developments in decades. Flash sintering, which was reviewed in a feature story in the May issue of the Time for sintering (s) Flash sintering: potential energy 100000 10000 1000 100 10 10/21/2010 Seconds Minutes Hours Flash Sintering savings SPS FAST Hot Press Conventional Energy savings Huge potential energy and cost savings. • How to supply the current to be supplied to the ceramic? Can noncontacting 600 800 1000 1200 1400 Furnace T (°C) 1600 electrodes work? M. Cologna-MS&T 2010 ACerS Bulletin, is similar to the traditional sintering/kiln process, but with a special twist: The heating takes place in the presence of an electric field. Because of the effects of the electric field, as the ceramic object reaches a critical (and relatively low) temperature, it sinters in a few seconds rather than hours and hours. The cautious enthusiasm for flash sintering among ceramic scientists and engineers has started to spill over into the manufacturing community. That is because the potential energy and CO₂ emissions savings from flash sintering in the ceramics and glass sectors is staggering. Indeed, in the ACerS Bulletin story, University of Colorado\'s Rishi Raj predicted that a place to start introducing flash sintering into manufacturing might be to develop a new kiln system for making ceramic tile, an industry where energy costs are high and business competition is intense. He mentioned that one challenge would be developing a noncontact electrode system to provide American Ceramic Society Bulletin, Vol. 92, No. 5 | www.ceramics.org the electric field. 15 The noncontact electrode challenge must have been solved, because an online newspaper in the United Kingdom, The Business Desk.com, reports that at Ceram, \"Work has started on a kiln that is to be the basis for technology that could cut energy costs for ceramics firms by up to 30 percent.\" The newspaper says Ceram (a subsidiary of British Ceramics Research and a well-known international company focused on materials testing, analysis, and consultancy) is calling the effort the Low-Energy Firing Project and describes it as an \"80-feet-long commercial-scale kiln.\" It also reports that construction of the new kiln was supposed to be completed in April, and testing to begin in May, with results available before the end of the year. The story intriguingly quotes David Pearmain, the LEFP project manager, who says, \"The potential of this work is really exciting. We think we can reduce firing times as well as temperatures, 3 Credit: Marco Cologna & Rishi Raj, University of Colorado.) 4 Onews & trends (Credit: Schott.) so there could be very, very significant advantages for the sector.\" Schott reports progress in manufacturing ceramics for use in advanced lens systems and LED technology There is increasing interest in the use of transparent and translucent ceramics, but much of the work has been to develop proof-of-concept and small-run products. The interest is driven in large part because ceramic-based optical components would have several property and manufacturing advantages over their glass counterparts. Although this use of ceramics has been held back by the lack of large-scale production techniques, Schott Research and Development now says in a news release that it has laid important foundations on manufacturing optical ceramics in a reproducible manner. This advance is the result of work by Schott as part of a special joint project funded by Germany\'s Ministry of Education and Research (BMBF) called \"OptokeraMat.\" Business news Corning announces increased quarterly dividend and new $2B share repurchase program (www.corning.com)...In a brutal solar market, Sweden\'s Midsummer looks to optical disk techniques for solar (www. midsummer.se)...Saint-Gobain wins top Cleantech award (www.saint-gobain. com)...New report: Global cement market to 2017 (www.researchandmarkets. com)...Cemex, Columbia U., and CCNY sign research agreement on alternative fuels research (wwww.cemex.com)…… Schott provides optical glasses with the lowest tolerances for refractive index and Abbe number (www.schott.com)...GE Aviation to build new production facility (www.geaviation.com)...

Chinese ceramics hurt Besides Schott, a partial list of participants in OptokeraMat includes Perkin Elmer, Braunschweig University of Technology, IBUtec, B&M Optik, Ceramtec, and the University of Erlangen. OptokeraMat has been a three-anda-half-year effort begun in 2009. The basic goals were to develop ceramic optical components that have high IR and UV transmisAccording to Schott, the manufacturing of transparent or translucent ceramics is based on a sophisticated process chain. Depending on the application, highly reactive oxide nanopowders of various compositions are mixed, doped, homogenized in liquid media, and then dried again. Afterward, they are pressed into shapes, such as, optical lenses, and sintered into ceramics inside a special high-temperature furnace up to 2,000°C inside a vacuum or 1,800°C in the open air. The sintered parts are then cut and polished for further processing. sion, high refractive indexes, are chemically stable, can be easily and reliably doped, and can be manufactured relatively efficiently.

With the collaboration now coming to an end, Schott says participants have accomplished much of what OptokeraMat set out to do. In the company\'s release, Yvonne Menke, materials development manager for Schott R&D, says, \"We have now succeeded in meeting the long-held wishes of the optical industry for a new transparent material for use in photography and other types of imaging devices. And we are paving the way for highly efficient LED systems.\" With reproducible optical ceramics, Schott says engineers can now exploit the superior thermal and mechanical qualities, high optical refractive indexes (some greater than 2), improved dispersion properties, and ability to create gradient materials. “This opens up new areas in the Abbe diagram—a diagram that systematically depicts the properties of optical materials—which glass was never able to address before. In other words, optic designers now have a larger toolbox to work with,\" explains www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 5 Volker Hagemann, senior scientist at Schott. According to the company, one of the applications will be camera lenses that can be made smaller and contain fewer color defects and aberrations. In addition, the lenses will enable new classes of cameras used for geo-observations that could be used on Earth and in space in searches for raw-materials deposits. For energy efficiency and lighting applications, Schott predicts a new era when engineers will use ceramic materials for color conversion use with LEDs. Typically, part of the light from blue LEDs must be converted to white for commercial lighting. Schott says in the release that the current color conversion materials are “not nearly as heat resistant as a fluorescent ceramic manufactured at temperatures in excess of 1,600°C. In combination with highintensity LEDs or laser diodes, the outstanding temperature stability and thermal conductivity of these ceramic converters allow for new light sources to be developed. Their luminance is two to three times higher than that of a typical xenon burner. Areas of application include beamers, next-generation digital projectors, and headlights.\" OptokeraMat, itself, was created under a BMBF initiative begun in 2007, \"Materials Innovations for Industry and Society\" (WING). According to its web page, WING is \"[T]he first program to integrate traditional materials research with the basic discipline of chemistry and with nanotechnology. Besides combining basic research and applied materials research with the aim of accelerating the transfer of results, the new program also takes account of technology-driven changes in market conditions. The materials manufacturers have often only a minor share in the eventual high-value creation with the component or system produced although they have covered most of the cost for research and development.

A report and speech by Willetts in January of this year called for research in “eight great technologies.\" Three of the eight are included in this funding announcement. Willetts says in a news release, “This £85 million capital fund will boost our research capability in advanced materials, energy storage, and robotics and autonomous systems. It will keep the UK at the forefront of science and innovation.\" David Delpy, the EPSRC\'s chief executive, also notes in the release, \"The work will help develop new ways of storing power, new materials that can aid manufacturing and other industries, and further developing how autonomous systems communicate, learn and work with humans.\" The call for proposals describes the EPSRC\'s strategic interest by noting, \"Advanced materials are instrumental in the generation of long-term economic growth and jobs for the UK, and reducing the time required to bring discoveries to the market has been recognized by global competitors in being a key driving force behind a more competitive manufacturing sector and economic growth. Focus should be on materials designed for targeted properties and on seeking to address the aims of this initiative, i.e., reducing lead times, tackling sustainability of materials, and discovering new materials types.\" The EPSRC acknowledges that there are some \"particular priorities offering the greatest potential to lead to new market opportunities or underpin the competitiveness of high-value existing sectors. These include advanced composites, low-energy electronics (including EPSRC Previously, the authors write, it was thought that ceramic pottery provided hunter-gatherers with \"attractive new strategies for processing and consuming foodstuffs.\" The interdisciplinary team from the UK, Japan, the Netherlands, Pioneering research and Sweden used modern chemical and skills metamaterials), materials for energy, high-performance alloys, and nanomaterials for health.” A total of £73 million eventually is to be targeted for advanced materials. Lessons from the ancientsengineered ceramic materials and climate change Although advanced ceramics are currently being developed and used to help solve pollution and climate challenges, could there be more new applications in which ceramic materials become a \"revolutionary new strategy\" and worthy of investment to meet today\'s climate challenges? A new paper from researchers studying ancient ceramic pottery says that appears to have been the situation with our forebears. In ancient times, pottery was the engineered innovation that met the needs of the contemporary people. \"Pottery was a hunter-gatherer innovation that first emerged in East Asia between 20,000 and 12,000 calibrated years before present,\" write the authors in the abstract of a new letter in Nature (doi: 10.1038/ nature 12109). The Nature letter reports on how an ancient society inhabiting the Japanese islands used pottery in the Late Pleistocene era as severe climate changes influenced their lifestyles. The time frame known as the Jomon period spanned from about 14,000 BC to 300 BC and overlapped with the ice age climate change that characterized the Late Pleistocene era. The region\'s huntergatherer culture was fairly complex and produced a plethora of pottery for practical and ceremonial uses. analysis tools to study the char residue in Jōmon pottery, and, surprisingly, they found lipids that indicate the pottery was used for the consumption of fish. In a press release, Oliver Craig from the Department of Archaeology at the University of York, UK, describes this use of pottery by a foraging society as a \"revolutionary new strategy for the processing of marine and freshwater fish, but perhaps most interesting is that this fundamental adaptation emerged over a period of severe climate change.\" He speculates that the relative abundance of food under water “provided the initial impetus for an investment in producing ceramic containers .... ,, Innovative ancient cultures engineered ceramic pots as they adapted to severe climate change.

Candidate statement Upon earning my BSc in ceramic engineering from the NYS College of Ceramics at Alfred in 1982, I was fortunate to be hired as an engineer at the University of Rochester\'s Laboratory for Laser Energetics, where I had the chance to \"learn optics,\" but more importantly, to see first-hand, the benefits of interdisciplinary research and training. My early career focused on optical materials and involved active participation in the optics and glass science community. My professional \"home\" was, and has remained, the ceramics and glass community through my numerous activities within ACerS. My primary affiliation over the past three decades with the Society\'s Glass and Optical Materials Division has focused on enhancing membership—leading efforts to attract and retain the next generation of leaders (students and young professionals) and promoting the cross-disciplinary focus of our programs. This focus includes attracting global researchers outside of the ceramics field to GOMD and the Society. To these ends, I led international glass and ceramics activities through my participation in numerous International Symposia in Non-Oxide Glasses conferences, initiation of the first ACerS division meeting outside the US (the EURO-GOMD 2014 conference to be held in Germany and cosponsored with Director candidates John W. Halloran Professor, Department of Materials Science & Engineering, University of Michigan, Ann Arbor, Mich. Candidate statement I am honored to be nominated for the Board of Directors, and I hope I have the opportunity to serve The American Ceramic Society on the Board. Ceramics are critical in an 10 Read extended candidate biographies at www.ceramics.org. the DGG), and participation in other glass-related conferences. Beyond ACerS, I have tried to extend awareness of the importance of glass and ceramics to the optics community in the Optical Society of America and SPIE. These efforts have two common threads, that have and will-directly benefit ACerS. • Each provided an opportunity to engage students and young professional researchers early in their careers so they can experience the benefits of professional networks in our glass and ceramic community. • Each broadened and strengthened the image of ACerS and its support of US research and education in ceramic and glass science and engineering among our international peers. This latter point supports the Society\'s goal to broaden its international visibility and membership, to become a more diverse entity, and to be the leading ceramic society among our professional society peers. Through these efforts, I have made significant contributions to the efforts of many, in growing ACerS\'s visibility—not only in our community, but across disciplines related to ceramics and glass worldwide.

However, we are identified not with particular industrial applications, but with a particular class of materials. Many engineers active in our field were not educated as ceramists, and many do not yet think of ACerS as their professional \"home.\" We need to work diligently to attract new members to our Society, engage their participation in our conferences, and submit papers to our publications. engineering, New York State College of Ceramics at Alfred University, 1992.

Edgar LaraCurzio Distinguished research staff member and leader of the mechanical properties and mechanics group and director, High Temperature Materials Laboratory, Oak Ridge National Laboratory, Oak Ridge, Tenn. Candidate statement Materials, including glasses and ceramics, enable the technologies that shape the way we live today, and they hold the key to addressing formidable challenges that result from population growth, increasing competition for limited resources, and the aspirations of emerging economies to achieve higher standards of living. I envision The American Ceramic Society maximizing its impact nationally and globally. First, at the national level, ACerS can become the forum of choice where industry, universities, and research organizations meet to exchange ideas, knowledge, and information to help strengthen STEM education and to foster the innovation and competitiveness that will enable a strong manufacturing sector and continued development of materials for national missions. Second, at a global level, ACers must continue to be the information exchange hub for the worldwide ceramics community, where scientists, engineers, and educators converge to address challenges that transcend national boundaries, particularly the development of affordable materials-based solutions to energy, environment, health, and infrastructure challenges. It is an honor to be considered for a position on the ACers Board of Directors. The Society has provided me with great opportunities to develop my leadership skills, which I pledge to use to help multiply, in a nonlinear fashion, the many contributions of its active members and thus maximize the Society\'s impact at the national and global levels.

Tatsuki Ohji Prime senior research scientist, National Institute of Advanced Industrial Science and Technology, Japan, and designated professor, Meijo University, Japan. Candidate statement It is my great honor to be nominated as a candidate for the ACerS Board of Directors. I have been involved with ACerS over the past two decades, which has given me an excellent opportunity to work with many ceramic professionals from all over the world. I have served in various capacities in the Engineering Ceramic Division, including chair (2010-2011), counselor, and, currently, trustee. For many years I have been an associ ate editor for two of ACerS journals: JACerS and IJACT. I have organized and chaired more than 20 symposia at the annual ACerS ICACC meeting and PACRIM meetings, and have edited 27 conference proceedings volumes. I also have been involved at the society level through the Nominating, Volunteer Structure Project, John Jeppson Award, Rustum Roy Lecture, and Book Publishing Committees. I have gained valuable insights through these involvements. I firmly believe that ACerS should be the global leader in advancing ceramic science and technologies to the next generation because these technologies will play a key role in the sustainable development of society. ACers should be the primary resource of scientific knowledge, technical information, education, networking, and professional development for the global ceramics community. In terms of membership growth and development, ACerS could attract and serve ceramic professionals, particularly young ceramic researchers and engineers, around the world through innovative programs. It could further promote interaction and collaboration with other international material societies for the advocacy of ceramic materials and technologies. I hope that I can contribute toward these goals during my tenure as a board member.

Education Integration Committee President\'s Council of Student Advisors integrates with the EIC By Aaron Lichtner, PCSA Programming Committee chair Immediately following the January PCSA meeting, the newly appointed officers participated Lichtner in a teleconference of the Education Integration Committee (EIC) where cryptic abbreviations such as SAC (Student Activities Committee), NICE (National Institute of Ceramic Engineers), YPN (Young Professionals Network), and CEC (Ceramic Education Council) were casually lobbed back and forth among members Geoff Brennecka, Kristen Brosnan, Kevin Fox, and others. Although overwhelming at first, the members of the EIC went above and beyond Education Integration Committee Subcommittees CEC reps EIC Chair Representatives Keramos (Pres.) PCSA (Chair) NICE reps Staff Liaison YPN SAC reps to make sure that I, along with my fellow President\'s Council of Student Advisors (PCSA) members, achieved firm footing for the new year. We quickly realized that the EIC had big plans concerning educational involvement, and the enthusiastic PCSA members were all too happy to take part. Under the umbrella of the EIC, the At-Large (Optional) PCSA hopes to foster new interest in ceramic education. As part of this push, the PCSA is moving their annual meeting to MS&T beginning this fall and hopes to increase the impact of the PCSA across the broader community of materials science and engineering students. In addition, there are a number of 12 www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 5 events that the PCSA is helping to orchestrate in conjunction with the other members of the EIC. With the assistance of the CEC, the PCSA organized informal round-table discussions at PACRIM10 with representatives from industry, academia, and national labs at each table to answer student questions about the field and what awaits them in the future. Together with the SAC, the PCSA is working with the Material Advantage Committee, Keramos, and other partner societies to coordinate an exciting and diverse group of student activities at MS&T, including technical and professional programming, contests, and industry tours. The CEC and PCSA also are developing a comprehensive list of faculty contacts, which will be useful for distributing information regarding student education opportunities. The PCSA currently is working with the YPN to provide opportunities for students and young professionals to get involved in Society activities of all types and retain these members as they advance in their careers. The members of the PCSA are proud and excited about what we are attempting to accomplish and truly none of it could be happening without the support of the EIC. However, there is always more that could be done. If any of the above events sound intriguing, or if you yourself have an idea of how to better address the future of ceramics education and student participation, I encourage you to get involved. Members of the EIC and PCSA are ready and willing to go that extra mile, a fact that was made clear to me that January afternoon during my first EIC meeting.

The lighting unit can produce 200 lm/W, a level that Philips claims is a record and roughly twice the efficiency of standard fluorescent tubes. Fluorescent tubes already are among the most energy-efficient forms of lighting, achieving 100 lm/W, or more, and are fairly inexpensive. At least one of the downsides of fluorescent tubes is the mercury content and related disposal issues. a Philips says one way to think about the company\'s innovation is that 7.5-W version of its TLED will produce the same amount of light as a 100-W incandescent lightbulb. The company, with some justification, also argues that the TLEDs could cut lighting energy use in half. A news release says, “In the US alone, for example, fluorescent lights consume around 200 TWh of electricity annually. If these lights were all replaced with 200-lm/W TLEDs, the US would use around 100 TWh less energy (equivalent to 50 medium-sized power plants), saving more than $12 billion and preventing around 60 million metric tons of CO2 from being released into the atmosphere.\" The other side of that coin is that some consumers may nullify some of the theoretical energy savings by increasing their overall level of lighting. Nevertheless, Philips\' work represents a breakthrough. According to a company technical document, the TLED achieves its \"high-quality white light” by leveraging the high efficiency of InGaN blue LEDs and carefully combining their output with a red LED. Some of the InGaN blue LED output is converted into green via a phosphor absorption/re-emittance system. The mix of blue, green, and red delivers the desired color, temperature, and color-rendering index. E-glass fiberglass flywheels for low-cost energy storage E-glass-already a workhorse reinforcement for fiberglass composites used for everything from shower doors to printed circuit board platforms to boats to storage tanks, and more-may turn out to be the material of choice for a high-tech energy storage system. Flywheels have to be durable because of the enormous centripetal force that can be generated. Existing designs for power grid-scale flywheels are based on carbon-fiber composites, but a flywheel technology built around E-glass fiberglass is in development, thanks to an infusion of money from the online group-funding website, Kickstarter. (Credit: Phillips.) Bill Gray, flywheel innovator and founder of Velkess Inc., concedes that carbon-fiber polymer composites are six to eight times stronger than E-glass composites. However, according to a VELKESS The Velkess energy storage system centers on a low-cost E-glass composite flywheel housed in a vacuum unit, such as the prototype pictured. his company\'s E-glass composite is 10-20 times stronger per dollar and that it will store 10-20 times more energy per dollar. The company\'s Kickstarter webpost says that the key to reducing the cost of flywheels is to use materials that are flexible. Traditional rigid flywheels, Gray says, require expensive, precision machining. Velkess (VEry Large Kinetic Energy Storage System) turned to an E-glass composite design because, “[The] flexible system embraces the natural dynamics of the rotor, redirecting any stray energies into stabilizing counter forces. By working cooperatively with these natural rotor dynamics, we gain excellent control of the rotor system without having to crush out its irregularities.\" A company video shows the company\'s \'s prototype 25-lb flywheel, which it says can store 0.5 kWh of energy for 2 kW of power. The goal is to scale-up to a 15 kWh energy storage capacity, which will require a flywheel weighing about 750 lb. The flywheel will be contained in a vacuum housing. Where mechanical bearings are used, they are made of silicon nitride. Thermal sensors trigger a shutdown if the internal temperature increases, which could indicate the possibility of an imminent bearing fracture. Gray claims that flywheel systems will cost about the same as lead-acid batteries, but that they will last much longer, with much lower environmental cost. (Credit: Velkess.)

The thrust of the paper was that rugged ceramic materials could be made intrinsically hydrophobic through the use of rare-earth oxides. They wondered if they could reverse the hydrophilic tendency of ceramics by interfering with the hydrogen bonding and thereby prevent the ceramic from accepting electrons from water. The investigators\' insight, according to the paper, is that rare-earth oxides have unfilled 4f orbitals, but these orbitals “are shielded from interactions with the surrounding environment by the full octet of electrons in the 5s²p outer shell.\" The introduction of rare earths into the ceramic composition, then, might prevent the bonding and render the material hydrophobic. Led by Kripa K. Varanasi, a materials scientist, the group tested their idea by making simple ceramic disks from powders composed of pure rare-earth oxides (REOs) of 13 elements in the lanthanide series-from cerium oxide to lutetium oxide. The fourteenth, promethium oxide, was eliminated because it is radioactive. They polished the disks to a mirror finish to minimize roughness and texture effects, and then put them to several successful tests. The authors write, \"As hypothesized, all the REOs are hydrophobic: water contact angles range between 100° and 115°. Also, the polar component of the surface free energy for all REOs was found to be negligible. Moreover, there is minimal variance in the wetting properties over the entire series.\" Moving closer to application-related properties, the group tested the disks with steam condensation, water droplet impingement, high-temperatures, and abrasion wear. These tests \"demonHydrophilic Al₂O <<10±4° (b) Hydrophobic R₂O Comparison of hydrophilic alumina (a) and hydrophobic ceria (b). strated dropwise condensation, complete water droplet bounce-off, and sustained hydrophobicity after high-temperature exposure and abrasion.\" Beyond demonstrating that some ceramics could be intrinsically hydrophobic, the Varanasi group also had a practical goal. They say, for example, that hydrophobic ceramics could play an important role by improving the efficiency of steam-based energy generation. In a separate Nature article about this research, Varanasi says a problem with steam generators is that water condenses on the rotating blades of the turbine and causes energy loss. He says the efficiency loss from this effect could be as great as 30 percent. Likewise, with wind turbines, accumulated water can freeze on turbine blades, again leading to efficiency losses and, perhaps, catastrophic failure. He says that in both examples, Bare silicon 102+39 a superhydrophobic surface composed of the REOs could make an enormous difference. As ceramists and other materials scientists and engineers know, there are many reliable methods for applying ceramics surfaces that could be employed to add REO hydrophobic surfaces to substrates, although the researchers caution that the effects of material geometries and thermal expansion mismatches would have to be considered. But, overall, using the REOs to achieve hydrophobic surfaces is not all that difficult, and, not surprisingly, Nature reports, \"Varanasi is now working with energy and technology companies partnered with the MIT Energy Initiative, which cofunded his work, to test the ceramics in real-world applications.\" CeO2 Er₂O3 A comparison of filmwise steam condensation on silicon versus the two REO hydrophobic surfaces.

Starting in September 2014, all new passenger vehicles and many lightweight commercial trucks in regions covered by the European Commission\'s rules will be required to have \"Euro 6\"-certified engines. Similar standards will roll in at staggered dates for midweight and heavyduty trucks. In response, vehicle manufacturers and various research groups have accelerated their filtration R&D. Switzerland\'s Empa is one of these groups, and researchers there say they are excited about some unconventional structuring of the main filter components-typically ceramic substrates-that they say will enable manufacturers to meet pollution goals. Heretofore, the standard diesel emissions filter has been an extruded honeycomb-structured ceramic substrate (e.g., cordierite) that has a light coating of a catalytic material, such as platinum or palladium. The substrate-catalyst combination allows the filter to convert NO and CO in the exhaust and capture particulates (soot). The honeycomb monolith substrate can withstand the stresses of temperature cycling during normal use and during \"regenerative\" cycles when aggregated soot is removed. The conventional approach to engineering these filters is to allow exhaust gasses to pass through relatively easily while providing maximum exposure to the surfaces bearing the catalyst. Turbulence is something to be avoided. However, the Internal Combustion Engines Laboratory at Empa says there is a downside to the honeycomb monolith: The flow of the exhaust gasses is distributed unevenly. Most of the exhaust gasses pass through the center section of the filter, creating a high-temperature zone and using much less of the outer regions of the honeycomb. To compensate for the unused regions, manufacturers make the honeycomb filters relatively long. The Empa group says that besides adding general manufacturing costs, the extra length also uses more of the expensive catalytic material. Empa researchers\' novel idea, which began to emerge a few years ago, was to embrace the turbulence of the exhaust and put it to use to distribute the gasses more evenly. But, a rugged ceramic substrate would still be needed. The Internal Combustion Engines Lab turned to researchers in Empa\'s High-Performance Ceramics Laboratory for assistance. Instead of relying on the straight-through openings of a honeycomb, the ceramics lab began to tinker with a special catalyst-coated ceramic foam, which they subsequently named \"Foamcat.\" The structure of the foam encourages the turbulence to more evenly distribute the exhaust through the filter. \"Honeycomb\" diesel exhaust filter, left, compared with Empa\'s ceramic foam substrate filter, right. EMPLO This damaged honeycomb filter gave Empa researchers the idea of developing Foamcat. A small area of the monolith has melted, but neighboring areas are almost unused, indicating that the exhaust gas flow is uneven. To filter engineers, the Empa approach probably raises several questions, especially in regard to the mechanical strength of ceramic foam and to the negative effects of the turbulence. In response, a news release from the institute says, \"[S]cientists succeeded in increasing the mechanical strength of the material many times over. Currently, the research team is working to optimize the structure of the ceramic-the foam substrate has a greater air resistance than the monolith that results in a slight comparative increase in fuel consumption. Using sophisticated computer simulation techniques, the Empa team has developed foam structures that reduce the air resistance without affecting the necessary turbulence.\" Empa says the surface area of the Foamcat substrate is much more efficiently used than a honeycomb monolith substrate. It claims that the efficiency is so improved that the Foamcat filter can match the performance of a honeycomb filter at half the length and with onethird of the expensive catalysts. Whether vehicle manufacturers ultimately embrace the ceramic foam design remains to be seen. Empa says it has been partnering for more than a year with catalyst-maker Umicore and diesel engine manufacturer Fiat Powertrain Technologies to do field tests with Foamcat filters. It also says that Swiss electrical utility IWB has been testing a vehicle fitted with the Foamcat filter for 18 months. The stakes are high. According to a document on the Euro 6 standards prepared by Cummins, all NO emissions will have to be 75 percent less and particulate matter will have to be 66-95 percent less than current \"Euro 5\" limits.

With this goal in mind, investigators from the University of Erlangen-Nuremberg (Germany) and Imperial College London (United Kingdom) recently announced that, for the first time, they can demonstrate that a type of bioactive scaffold based on 45S5 Bioglass just might be able to foster the right type of vascularization that surgeons are looking for in implant design. A paper on their work, titled \"Evaluation of angiogenesis of bioactive glass in the arteriovenous loop model,\" can be found in Tissue Engineering C (doi:0.1089/ten.tec.2012.0572). In cooperation with two physicians in the Department of Plastic and Hand Surgery in Erlangen, Andreas Arkudas and department head Raymund E. Horch, the researchers tested a Bioglass scaffold and grew tissue using an arteriovenous loop (AVL) model in rats. An AV loop is a commonly used hybrid blood vessel, formed via microsurgery, which joins a small arterial vessel with a vein counterpart. The AVL stays connected to the animal. The researchers made the scaffolds using 45S5 Bioglass powder and a foam replica technique developed by the group of Aldo R. Boccaccini, an ACerS Fellow and head of the Institute of Biomaterials in Erlangen. They then filled this Bioglass-derived granular matrix with fibrin gel. Finally, they placed the scaffold in a small Teflon isolation chamber containing the AVL, which was left in the rats. After about three weeks, they removed the isolation chamber from the rats and examined the resultant combination of scaffold and newly grown tissue using microcomputed tomography and histology. They found extensive axial vascularization of the matrix, confirming the significant potential of the material in tissue engineering applica(A) (B) Researchers created samples of a vascularized engineered tissue based on Bioglass. They placed an arteriovenous loop in a Teflon isolation chamber that was filled with the sintered 45S5 Bioglass-granulated matrix and fibrin gel. (A) arteriovenous loop placed on the first half of the matrix. (B) Chamber filled with the complex matrix. tions. Because other research has shown that Bioglass can have a positive effect on the growth of new bone tissue, this in-vivo study particularly suggests that it should be possible to use the 45S5 for the development of vascularized bone tissue. Axial vascularization is significant because these vessels should allow the microsurgical transfer of the biomaterial independent of local conditions at the recipient site. Moreover, they found that the newly grown microvessels were immature and had consistent, small diameters. This means the microvessels would be prime for continued growth once implantation occurs. Implantation could occur as easily as removing the AVL pedicle from the isolation chamber and transplanting it to another site where, for example, bone or another type of tissue repair is needed. The hope is that this technique, or one similar, could be used to engineer tissue to address large-bone defects and eventually replace the practice of harvesting bone graft material from, for example, a patient\'s pelvis, a method that often causes additional and serious medical complications. The robust possibilities for Bioglass were touched on in the May issue of the ACerS Bulletin in an interview with 45S5 inventor Larry Hench. In the article, Hench describes the emergence of what he call the \"third generation\" of biomedical glasses and other bioceramAmerican Ceramic Society Bulletin, Vol. 92, No. 5 | www.ceramics.org WD HV Spot Mag Sig 11.0 mm 20.0 kV 4.5 50x BSE 2.0mm01Cu 10 01.11 SEM of example of Bioglass scaffold.

Graphene A ceramic engineer or scientist unfortunately must admit that there is an unwelcome member of the family among us-iron oxide, or rust. This unpleasant family member is disruptive at best. More often it is destructive, nearly impossible to nanocomposite control, and a consumer of resources that coatings for protecting loware devoted to it in an attempt to mitigate its impact or at least slow it down. Metal bars, wires, and sheets require protective coatings to prolong their use on exposure to service environments wherein they inevitably encounter corrodant species and conditions alloy steels from conducive to the initiation of rust formacorrosion By Robert V.

Society invests enormous amounts of time and financial resources to rust prevention, repair, and replacement. Indeed, the Department of Defense has a long history of fighting rust (Figure 1), and the Government Accountability Office estimates that today the United States military spends more than $20 billion per year in corrosion-related expenses. As the advanced manufacturing industry in the United States rejuvenates, sustainable processes and materials will be increasingly important. 1,2 New materials will offer opportunities for new solutions to old problems. Graphene and carbon nanotubes represent a class of new materials with unique properties that are just beginning to find applications in emerging and www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 5 existing industries. This article presents promising results of an active-passive approach to protecting low-alloy steels from corrosion using a nanocomposite coating comprising exfoliated graphene or multiwalled carbon nanotubes dispersed within a polyetherimide matrix. Keeping rust at bay The earliest reports of efforts to prevent fouling of surfaces date back to 412 BC when explorers coated the wooden hulls of ships with tallow and pitch poisoned with arsenic and sulfur to keep barnacles at bay. Today, zinc-based alloys are the \"gold standard\" sacrificial electroactive corrosion coatings for low-alloy steels. The extent of protection is proportional to the thickness of the coating, with inevitable cost penalties for sensitive components requiring prolonged corrosion protection.3 Zinc coatings are less ductile than the steel substrates they protect. Deformation of the steel can induce flaking or cracking of the galvanic coating and compromise the coating\'s corrosionresistance properties. Furthermore, zinc coatings are susceptible to fluctuations in precursor prices, an issue that has increased in importance in recent years. Zinc and tin prices spiked dramatically in 2005-2006, but have stabilized since the discovery of new mines and mitigation of supply chain restrictions. Nevertheless, many steel companies anticipate a severe shortage of zinc in 20 to 25 years resulting in substantial research efforts dedicated to mitigating reliance on this material. Manufacturers used chromium and various chromate coatings to plate carbon steel, zinc, and aluminum substrates for most of the last century because of the ease of plating, excellent corrosion resistance, remarkable wear resistance, Vickers hardness values ranging up to 1000 kg/mm², and lustrous surface finish.5 However, because of the potent carcinogenicity of hexavalent chromium and environmental concerns regarding disposal of electroplating dips, and the harmful effects of the mist created during the plating process, 6 the European Union\'s stringent regulations- the Restriction of Hazardous Substances (RoHS) directives—limit chromate use to 0.1 wt% in conversion coatings. 7 The growth of chrome electroplating and metal-finishing shops paralleled the boom in the US steel industry between the late 19th century to the middle of the 20th century as railroads linked an integrated supply chain across the Great Lakes region that would become the bedrock of the manufacturing base. Historically, small- and medium-sized customized metal-finishing enterprises dominated this sector, and, not surprisingly, these businesses were buffeted by the upheavals in the steel industry starting from the 1970s. Despite the nation\'s increasing reliance on imported steel, metal-finishing shops continue to be important to the manufacturing economy in traditional steel towns across the \"Rust Belt.\" In the Buffalo-Niagara region that is home to the primary authors of this article, for example, the closing of the Bethlehem Steel plant in Lackawanna, N.Y., devastated the local economy. Even so, the Brookings Institute estimates the region provides more than 14,500 jobs directly related to metal finishing, fabrication, and tool manufacturing and has enjoyed strong job growth during the last two years. Beyond the economics of the steel industry, increasing alarm regarding the environmental impact of heavy metals from the metal finishing industry is reframing the national conversation regarding the environmental consequences of a manufacturing economy. The Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the National Institute for Occupational Safety and Health (NIOSH) have issued successively more restrictive regulations regarding disposal of chromium-based effluents. The Clean Air Act, the Clean Water Act, the Resources Conservation and Recovery Act (RCRA), and the Toxic Substances Control Act directly address chromium concentrations in air, water, and soil. As the Buffalo-Niagara region, along with other manufacturing towns, seeks to once again \"seize the manufacturing moment,\" there is opportunity for a renewed focus on sustainability and susAmerican Ceramic Society Bulletin, Vol. 92, No. 5 | www.ceramics.org tainable materials, process efficiency, and additive approaches to manufacturing that could potentially bring innovation to metal-finishing, joining, and forming industries that will enable them to once again be important drivers of economic growth. Hybrid nanocomposites: Putting graphene to work in coatings The vast array of materials that have been tested as alternatives to zinc and chromate coatings includes engineered polymers, conductive polymers, polysiloxanes, metal oxides, thermally sprayed cermets, self-assembled monolayers, active corrosion inhibitor technologies, encapsulated monomers, and bioactive or biomimetic materials. Polymeric coatings have shown potential as corrosion inhibitors, but adhere poorly to metal substrates. 12,13 Nanostructured coatings show promise, but suffer from inherent porosity, which creates channels for water and ions to permeate the coating and corrode the metal surface. 14 5,9-11 There is growing interest in designing hybrid nanocomposites comprising multiple components, where the individual components act in concert to deliver corrosion resistance, formability, and adhesion to steel substrates. 15,16 Herein, we present a hybrid nanocomposite coating system that combines the electroactivity of carbon nanomaterials, such as multiwall carbon nanotubes (MWCNT) and exfoliated graphene, with the water impermeability and excellent adhesion properties of a specialty polymer, polyetherimide (PEI). The nanocomposite protects low-alloy steel substrates through an \"active-passive\" approach, serving as a physical barrier to water permeation, preventing formation of ion channels at the metal surface, and passivating the metal/metal oxide surface through electron depletion at the interface, likely through establishment of a Schottky barrier. 3,9,17,18 Two coating systems were studied: a graphene/ PEI composite with high loading of the nanomaterial filler; and a combined graphene/MWCNT/PEI system with a much lower loading of each filler to study synergistic effects between the two types of carbon nanomaterials.

Using in-situ polymerization, the carbon nanomaterials disperse in the PEI precursor (poly(amic acid), PAA) prior to polymerization, results in improved dispersion of the nanostructured carbon fillers in the eventual polymer matrix. The uniform dispersion of nanomaterial in the matrix, along with the remarkable adhesion of the tailored PEI to the steel substrate, facilitates improved corrosion resistance under accelerated corrosion testing conditions (Figure 2). 3,17 Figure 2. Synthesis and coating of nanomaterial-PEI composite coatings. SEM image of graphene platelets, chemical structure of polyamic acid, photograph of the graphene/PAA dispersions, photographs of two coating methods (wire-bar coating and spray coating) and an oven used for curing, and, lastly, photographs of the coatings on steel. MWCNT/PEI system also was tested, but it showed no enhanced corrosionresistance properties.) Graphene, a single-atom-thick layer of sp²-hybridized carbon atoms, has remarkable electronic, mechanical, and thermal properties. Since their discovery in 1991, carbon nanotubes have been researched extensively. However, their exceedingly high costs and environmental concerns have slowed large-scale commercial implementation. Many methods for producing graphene have been developed, but the facile non-oxidative solution-phase exfoliation of graphite is particularly interesting, because it is scalable and avoids the oxidative functionalization that tends to disrupt the л-conjugated structure (pristine aromatic ring system), which is critically important to many of graphene\'s remarkable properties. We denote exfoliated graphene derived from ultrasonication of graphite in N-methylpyrrolidone (NMP) as unfunctionalized graphene (UFG). 20 Several approaches exist for dispersing (Credit: Banerjee, U. Buffalo) A manufacturing perspective Applying coatings in a continuous process to low-alloy steel must be fully scalable, allow for high-throughput integration with rolling or casting processes, enable precise control of coating thickness, and not require expensive capital equipment. We have developed coating formulations that can be applied through standard wire-bar and spraycoating processes. The former translates readily to roller-coating (gravure, reverse roll, and knife-over-roll) methods, which tend to be preferred by many metalfinishing shops and steel mills, thereby requiring little retooling. In past work, we also demonstrated electroplating of graphene onto metal substrates from an aqueous solution using a process similar to chrome electroplating. 24 Although the results reported here correspond to NMP dispersions, research proceeds on aqueous analogs of these formulations. Graphene is a potential sustainable replacement for metals, such as zinc and chromium, especially if graphite byproducts from the steel industry can be transformed to high-quality graphene. The cost of sustainable coatings can represent a major impediment to their widespread adoption. As with any new material and the absence of economies of scale, reliable financial projections are yet to be conclusively established for the graphene production. Nevertheless, some industry leaders suggest that a price goal of $20 per pound for graphene is attainable in the short term and that costs of production could soon be as low as $5 per pound. Given the low graphene loadings in our formulations and the high efficacy of much thinner coatings (an order of magnitude thinner than sacrificial metallic coatings), the price proposition of the materials presented here is quite attractive. Related to sustainable manufacturing, previous work demonstrated the use of blast furnace gases to grow directly well-adhered layers of carbon nanotubes, multilayered graphene, and carbon nanofibers onto low-alloy steel substrates.25 After deposition of PEI, the carbonnanomaterial/PEI composite coatings provide excellent corrosion resistance. 17 This method represents an attractive route for designing a closed-loop process that reduces the carbon footprint of steel plants while adding value to steel substrates. Corrosion rate drops two orders of magnitude We synthesized UFG from natural flake graphite through ultrasonic exfoliation of graphite powder in NMP. The MWCNTs used in this study are more than 99 percent pure by weight and have outer diameters 13-18 nm with lengths 3-30 μm. Figure 3 depicts the overall process for depositing of PEI nanocomposite coatings.

The desired concentration of UFG or MWCNTs is added to the NMP and ultrasonicated to create a visually nonscattering solution prior to polymerization. The nanomaterial filler disperses well in the viscous UFG/PAA (or UFG/MWCNT/ PAA) (Figure 2) allowing it to be roller coated onto freshly cleaned and degreased low-alloy steel substrates (Figure 3). PEI is synthesized in-situ on the steel surface through an imidization reaction. Although the mechanism details have not yet been fully investigated, results show that the in-situ imidization protocol yields coatings with substantially improved adhesion of the polymer to steel, fashioning a robust composite with a dry coating thickness of 15-20 μm. 3,17,26 The m-phenylendiamine component prevents crystallization of the polymer and improves flexibility and formability as the coating adopts the contours of the low-alloy steel surface.³ The nanocomposite coatings were deposited by wire-bar coating (chemical coating) onto a clean cold-rolled steel surface using either an automatic film applicator or a spray coating method (Figure 2). The PAA was cured at 150°C for 5 min, followed by a 250°C curing step for 5 min to complete the imidization of the PEI (Figure 3) and to remove residual NMP. We characterized the UFG synthesized for use in the PEI nanocomposites by scanning electron microscopy and transmission electron microscopy as shown in Figure 4. UFG tends to agglomerate into large fragments on drying as shown in Figures 4(a) and 4(b). However, Figures 4(c) and 4(d) show that the UFG morphology is sheet like, adding to the flexibility of the coating and the formability of coated pieces. Notably, the agglomeration and phase segregation of UFG in nanocomposites is substantially mitigated by the in-situ polymerization approach. MWCNTs and graphene interact strongly with polyimides via strong л-л stacking interactions. Because of the structural similarity of these materials, good wettability and chemical compatibility between the matrix and the filler are expected. 20,27 The PAA envelopes the UFG platelets, and PAA chains interacting with UFG likely impart steric stabilization to the UFG colloids in NMP. Figure 2 shows the highly concentrated, stable UFG/ PAA dispersions without phase segregation or flocculation of the UFG filler after several months. Figures 4(e) and 4(f) show high purity of the MWCNTs with outer diameters of 13-18 nm and lengths of 3-30 μm. Analogous to UFG, bundling of MWCNTs is mitigated by ultrasonic treatment in NMP. Photographs of the coatings are depicted in Figure 2. A top-view inspection of coatings in the SEM reveals a fairly smooth surface finish with no cracks or visible pinholes. Furthermore, we observed no phase segregation of UFG or MWCNT fillers at the surface. MWCNT and UFG sheets are dispersed in the PEI matrix, as the SEM images of cross-sections of cryo-fractured surfaces of the free-standing composite samples show (Figure 5). Figures 5(a) and 5(b) show the PEI is relatively featureless. In contrast, clearly visible UFG and MWCNTs protrusions appear in the fractured composite surfaces (Figures 5(c)-5(f)). Figures 5(c) and 5(e) show that the MWCNTs and UFG sheets are well dispersed, and, again, there is no visible phase segregation of the fillers 21 Graphene nanocomposite coatings for protecting low-alloy steels from corrosion (a) (b) 10 μm 5 μm MWCNTS (c) (d) MWCNTS (e) UFG นค UFG 3 μm UFG 20 μm persion of the conductive fillers helps prevent delamination of the composite coating from the metal and appears to aid formation of a passivation layer at the metal surface. Potentiodynamic electrochemical tests (following the ASTM-G59 standard) measured corrosion behavior of coated samples, bare steel, and galvanized steel in saline environments. Figure 6 plots current density versus potential for samples tested in 3.5% NaCl solution. The current density for nanocom5 μmposite-coated samples was Figure 5. Cryo-fractured SEM images of (a) and (b) PEI (without filler), (c) and (d) 2 wt% UFG/MWCNT/PEI, and (e) and (f) 20 wt% UFG/PEI. from the PEI matrix. The images further suggest the presence of an amorphous polymer coating around the UFG sheets and individual MWCNTs. The excellent dispersion of the carbon nanomaterials in the PEI matrix is likely a result of the л-л interactions between the л-conjugated graphene basal planes and the aromatic moieties on the polymer backbone. 17,20,23,27,28 Such excellent disseveral orders of magnitude less (down to about 10-9 A/ cm²) than bare low-alloy steel and galvanized steel (which have current densities on the order of about 10-5 A/ cm²). This correlates directly to diminished corrosion of the steel surface and demonstrates the efficacy of the coatings as barrier materials. The potentiodynamic measurements provide further evidence of the formation of a passivation band from -0.243 V to 0.576 V for the 20 wt% UFG/PEI nanocomposite coating and from 0.010 V to 0.576 V for the 2 wt% UFG/MWCNT/PEI coating. The formation of a passivation band for the nanocomposite coatings-but not for PEI alone-suggests that the conductive carbon nanomaterials are important in forming the passivation layer at the metal surface. 9,17,26 Furthermore, incorporating UFG and MWCNTs in the coatings shifts the potentiodynamic plots to more positive potentials, suggesting more \"noble\" behavior for these systems. Although the precise nature of the passivation layer remains unclear, a Schottky barrier often is seen at metal/nanotube and metal/graphene junctions and requires more bias to facilitate electron transfer. 29,30 This type of potential barrier at the interface likely impedes the corrosion reaction by restricting the flow of electrons to the steel surface, which is required for oxidation. Also, the hybridization of graphene with metal surfaces can open a bandgap in the semimetallic graphene, resulting in semiconducting behavior for the metal/UFG interfaces. 31,32 Charge depletion from the passivating semiconducting layer also could suppress corrosion. The photographs in Figure 7 provide a qualitative measure of the relative corrosion rates of the various test substrates of samples immersed in 3.5% NaCl soluNew uses for carbon steel pipe thanks to corrosion- and wear-resistant claddings By Joshua Caris MesoCoat Inc. (Euclid, Ohio) has developed a high-density infrared (HDIR) process for applying a uniform, metallurgically bonded metal layer― or clad―to carbon-steel surfaces for corrosionand wear-resistance applications. Clad materials include the nickel-based superalloy, Alloy 625, and stainless steels as well as composites containing tungsten and chrome carbides. This new technology has the potential to be a \"game changer,\" especially in the emerging oil sands and shale gas industries. The advantages of this technology are • Fast application rate (coverage of 75-280 ft²/h with a single system); • Low potential heat input to the substrate (small heat-affected zone); • True metallurgical bond (bond strength greater than 75,000 psi); • Lower initial cost, lowest life cycle cost (50 percent reduction); and 224 22 • Better cladding (smooth, pinhole free, low dilu- (A slurry loaded with cladding powders is depostion, and no decarburization). HDIR processing is a heating and coating application technology that developed concurrently with lamp design improvements using broad frequency thermal emitters, such as plasma arc lamps and tungsten filament bulbs. Coupling these irradiation sources with reflectors of various geometries achieves the required irradiance (W/cm²) for surface processing. Tungsten filament lamps typically operate at temperatures between 2000 K and 4000 K. The Planck blackbody distribution peaks in the IR range. However, there is a broad distribution through the visible range, and the light appears white. Plasma arc lamps electrically induce a noble gas plasma within a water-cooled, fused quartz tube. These ceramic components are critical, because they are transparent within the IR, permitting containment of the plasma and transmission of the light required to melt and fuse the cladding. ited on the surface to be clad.) Oak Ridge National Laboratory developed the plasma arc lamp technology for cladding surfaces in the early 2000s. Recently, MesoCoat purchased exclusive rights to the technology and has since commercialized it. These lamps operate at a much higher temperature, approximately 10,000 K. At this temperature, the constrained plasma acts as a blackbody emitter with a peak primarily in the ultraviolet range. However, there are distinct IR peaks characteristic of the noble gas, argon in this case, superimposed on the blackbody background radiation. This high-intensity spectrum is collected and carefully reflected and directed to melt the slurry of corrosion- or wear-resistant alloy or composite to the surface of a component in what MesoCoat calls the CermaClad process. The focused plasma arc lamp emission has measured heat irradiances of 500-2000 W/ cm², which encompass the irradiance regime www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 5 tion for various durations: 0 h; 234.5 h; 1,752 h; and 3,144 h (the end of the immersion test). After 234.5 h exposure, extensive red rust formed on the lowalloy steel surface. Similarly, white powdery deposits on the galvanized sample suggest sacrificial corrosion of the zinc layer. The nanocomposite coatings and the filler-free PEI coating show no visible signs of corrosion. After 1,752 h of exposure to 3.5% NaCl solution, red rust formation on the galvanized steel sample indicates complete oxidation of the galvanic coating. The coating of the PEI-coated steel has partially delaminated, allowing for corrosion to begin. In contrast, the UFG/PEI and UFG/ MWCNT/PEI nanocomposite systems appear to have avoided such a fate. Finally, after completion of this test at 3,144 h, extensive corrosion across the test substrates is apparent for all samples, except for the two coated with 20 wt% UFG/PEI and 2 wt% UFG/MWCNT/ PEI. Some specks of corrosion are apparent for the latter two samples, especially under microscopic examination, but they are clearly superior to PEI alone or galvanized steel for protecting the low-alloy steel substrates from corrosion. (Despite the differences in appearance in the photographs, the two samples corroded approximately the same amount.) Weight-loss measurements provide a more quantitative perspective of the inhibitory properties of the nanocomposite coatings. The weight-loss measurements of the samples shown in Figure 7 were conducted per ASTM-G1. According to this protocol, the corrosion rate (CR) in millimeters per year is CR = 87.6(W/ DAt) (1), Current density (A/cm²) 102 10 10% 10 Galvanized steel Steel ΡΕΙ -2 wt % UFG/MWCNT/PEI 20 wt% UFG/PEI 10-10 10-12 Potential vs. SCE (V) Figure 6.

The calculated CR values for the samples are listed in Table 1. The 20 wt% UFG/PEI nanocomposite coating corrodes almost three orders of magnitude slower than bare low-alloy steel. The inclusion of UFG or MWCNTs also reduces corrosion by an order of magnitude over the pure polymeric coating. Conclusions In summary, tests show that two novel nonmetallic nanocomposite systems protect low alloy steels from corrosion. The in-situ copolymerization of an anhydride and a of continuous-wave lasers, but with several unique differences. Laser-processing light has a relatively small beam diameter from a monochromatic light source. HDIR processing takes advantage of a broad spectrum of irradiation with a focus area that corresponds to the diameter and length of the quartz tube containing the plasma. Because the irradiances are similar, a qualitative comparison is that laser processing is like a brush used to paint a portrait, while HDIR focused plasma processing is like a roller for painting a wall.

Freshour Congressional Visits Day (CVD), organized each year by the Material Advantage Student Program, was held on April 10 and 11, 2013, in Washington, D.C. CVD is a unique opportunity for materials science and engineering students to advocate for long-term funding for science, engineering, and technology through meetings with Congressional decision makers. Thirty-seven students and faculty from 13 universities attended this year\'s event. Security was tight because of sequestration. The students witnessed thousands of people rallying for immigration legislation on the Capitol lawn, which made getting around D.C. very busy and hectic. However, the weather was great, and the cherry blossoms were in full bloom. The CVD began with an opening reception on Wednesday, April 10. Three guest speakers presented the following talks to help prepare the students for the next day. \"Effective Communication with Hill Staff,\" by Deborah Koolbeck, vice president, Council on Competitiveness; • \"Materials Genome Initiative and How Various Programs are Responding,\" by Ashley White, Directorate for Mathematical and Physical Sciences, Division of Materials Research, National Science Foundation; and \"Life in an Office on the Hill,\" by Andrew Steigerwald, 2012-2013 MRS/TMS Congressional Science and Engineering Fellow, Office of Senator Sherrod Brown (D-Ohio). • Most of the students\' appointments with legislators were scheduled for Thursday, April 11.

Dahotre Vora Dahotre Structural ceramics, such as alumina, zirconia, magnesia, silicon carbide, and silicon nitride, are one of the most versatile groups of materials. These materials resist deformation at elevated temperature, exhibit excellent wear and thermal shock resistance, can be chemically inert, have superior electrical properties, and can be formed with low densities. These unique properties make them amenable to several applications in electronic, automotive, aerospace, textile, and medical sectors.¹ However, structural ceramics are extremely difficult to shape, fabricate, or machine because of their high hardness (about 1200-2200 Knoop hardness) and low fracture toughness (about 3-5 MPalm 1/2). These forming challenges have prevented these materials from making inroads into these applications. Furthermore, excessive tool wear, insufficient accuracy, and mechanical or thermal damage of the workpiece are limiting factors that prevent manufacturing of ceramic components using conventional machining techniques. Grinding remains the most often used convenControlling PC Alumina tional machining technique to machine or fabricate structural ceramics to good dimensional accuracy and surface finish.² Prohibitively longer machining times and higher operating costs (possibly higher than the actual material costs) are the major drawbacks. Because of the severe need for a reliable and cost-effective machining technique for ceramics, the laser-assisted machining process holds tremendous promise. As a noncontact process, it overcomes many of the drawbacks associ ated with conventional machining techniques. Furthermore, it is an innovative process of bulk material removal for efficient and rapid fabrication of complex structural ceramic components. Narendra B. Dahotre, professor of materials science and engineering, established the Laboratory of Laser Materials Processing and Synthesis (LLMPS) at the University of North Texas (Denton, Texas). The state-of-the-art research facility houses multiple high-power infrared laser systems (Figure 1). These lasers are specifically designed and configured for efficient, reliable, cost-effective, precise, and efficient machining and fabrication of advanced materials, including structural ceramics.

Development of a successful laser machining process requires understanding of the fundamentals of interactions between lasers and materials at multiple scales. The Dahotre group uses an integrated experimental and computational approach to understand material removal mechanisms and the resulting surface finish. For example, when a high-energy laser beam (about 106 J/m²) strikes the material surface during laser machining, the surface undergoes a sudden temperature increase caused by absorption of the laser energy. A temperature decrease follows, caused by self-quenching by the bulk material as well as heat losses from radiation and convective cooling, which, in turn, results in several physical phenomena, including heating, melting, vaporization, and plume formation (Figure 2).³ With sufficient laser energy density (about 106 J/m²) and laser-material interaction time, the surface experiences localized melting and vaporization. Surface evaporation involves the emission of neutral atoms or molecules of the material that shields the laser-material interaction zone. The vapor particles evaporated from the melt pool are significantly cooler and denser than the vapor-surrounding laser-material interaction zone. The evaporated particles condense back to the surface, causing a (Credit: Dahotre; UNT) 12 recoil pressure on the liquid melt pool underneath. For the higher-intensity laser beams (greater than 106 J/m²) and shorter interaction duration (0.1 to 10 ms), the magnitude of the resulting recoil pressure is very high and induces shock waves sufficient enough to generate a hydrodynamic melt motion in the liquid melt pool.³ As a consequence, the liquid metal is ejected out from the crater and creates a liquid pile-up or crown around it. At the end of the laser-material interaction (or end of laser pulse or interaction time), the liquid material tends to return to its place under the force of gravity. However, because of the self-quenching effects and higher cooling rates (about 105 K/s), the liquid material solidifies instantaneously and the tangential stress exerted by the surface tension of the material gives shape to the solidified material. As a result, a significant amount of material is removed and typical surface topography is generated during laser machining (Figure 2).4,5 Because these physical phenomena occur in a very small laser-material interaction zone and within a short interaction time, the in-situ measurement of corresponding signals is extremely difficult. In addition, the rapid processing speed and high level of heat generated during laser machining make it virtually impossible to conduct any real-time experimental analysis. Thus, the LLMPS group developed integrated experimental and multiphysics computational methods to effectively investigate the influence of laser processing parameters (laser energy, processing speed, pulse rate, etc.) on material removal rate and the corresponding surface finish. The study results show that the material removal rate and surface roughness increased with increased pulse rate (1 to 50 Hz) or with increased average laser energy density. 4, 5 Thus, optimized processing parameters allow effective control of the physical processes (melting, vaporization, etc.) to achieve various physical effects and to generate required attributes (material removal rate and surface finish) during laser machining of structural ceramics.

Similar to their corresponding binary carbide and nitride ceramics, they have high elastic moduli, high thermal and electrical conductivities, high chemical resistances, and low thermal expansion coefficients. Radovic On the other hand, they also possess metal-like properties. For example, they are relatively soft, and most are readily machinable, thermal shock resistant, and damage tolerant. Moreover, they can be compressed to stresses as high as 1 GPa and fully recover their original shapes on removal of the stress, while dissipating 25 percent of the mechanical energy. 2,3 They also have better creep resistance than most high-temperature metallic alloys. 2,3 Although research on the MAX phases in the compact, fully dense state has exploded since the 1990s, very few studies have focused on these materials in the porous state. Porous MAX phases deserve systematic study for a variety of reasons. First, controlling porosity and pore size allows tailoring of their Normalized compressive strength 1.0 0.8 + Ti₂AIC 0.6 0.40.2 Si, N₁ 0.0 0.0 0.1 0.2 0.3 0.4 1000 Porosity (a) (b) 2 μm 100 μη Figure 1.

(b) Field emission scanning electron microscopy images reveal the fracture surface of a postcompression, porous T₁₂AIC sample. Inset shows kinking and delamination of Ti₂AIC. mechanical and functional properties.² Second, using porous MAX phases as melt infiltration preforms creates an alternative for fabricating novel cermet systems. Example applications include magnesium melt infiltration into porous MAX phase preforms to make a new class of high-strength MAX phase/ magnesium composites with exceptional mechanical damping characteristics.4 Another application of porous MAX phases is for catalytic coatings in gas exhaust devices.5 Porous MAX phases are prepared by either incomplete densification during sintering of powders or by a replica method using a polyurethane sponge template. Although it is simple and straightforward, incomplete densification does not allow good control over morphology, porosity, and pore size. The replica method, on the other hand, allows good control of the pore size and morphology, but it is complex, time consuming, and not desired for fabricating samples with low porosity. More recently, investigators adapted the use of a NaCl pore former by Polonsky et al.6 during the 1960s to fabricate aluminum foams as a simple and inexpensive way of synthesizing porous Ti,AlC. This three-step method involves cold pressing a NaCl-Ti,AlC powder mixture, dissolving the NaCl in water, and pressureless sintering of the porous green body. The process yielded samples American Ceramic Society Bulletin, Vol. 92, No. 5 | www.ceramics.org with a large range of porosity from about 10 to about 71 vol% as well as a wide range of pore sizes, for example, 42-83 μm, 77-276 µm, and 167-545 µm.³ 3 NaCl is inexpensive and commercially available in a broad range of particle sizes. Organic pore formers can react with MAX phase powders during sintering and form binary carbides if they are not burned out completely at lower temperatures. However, NaCl can be removed easily and completely after cold-pressing but before sintering, and it eliminates the potential for reaction between pore former and MAX phase. Experimental investigations show that porous MAX phases tolerate damage well. Specifically, the compressive strength of Ti,AlC decreases almost linearly with increasing porosity (Figure 1(a)), but less rapidly when compared with common ceramics, including A₁₂O, Si̟N, and ZrO2,³ whose compressive strengths decrease dramatically with increasing porosity. This strength/porosity relation is caused partially by the kinking and delamination mechanism that is typical of deformation in Ti,AlC and, to a further extent, in all MAX phases. The SEM images of the fracture surfaces in Figure 1b reveal intensive kinking and delamination of porous Ti,AlC that dissipate a large amount of mechanical energy during crack propagation. Also, 31 Annual student section the relatively low standard deviations (from 3.9 to 16.0 percent) for compressive strengths provide additional evidence of the exceptional damage tolerance of TiAlC. Because of the wide range of porosity and pore size, even more interesting mechanical responses may be possible. References \"M.W.

At Worcester Polytechnic Institute (WPI), that dream is realized by almost half of the student body. For me, that meant nine weeks in Puerto Rico in the spring of 2010. However, this was not a trip to study island culture or become fluent in the Spanish language. Rather, I worked as a field ecologist sampling macroinvertebrate populations. At this point you may suspect I am trained in biology and am an avid outdoorsman. I am quite the opposite. The primary purpose of the trip was to experience a side of science and engineering that one would not normally encounter in their career path. The goal was to learn management skills, how to interact with others, and how to work outside of my comfort zone. My four-person team included a chemical engineer, a biologist, a biomedical engineer, and an aerospace engineer (yours truly). Indeed, our project was outside everyone\'s comfort zone. The project changed how I look at my discipline and how I look at others\' as well. I gained perspective on my work generally reserved only for one outside of my field. After all, for this project, I was very much an outsider in terms of discipline and culture. I felt similarly an outsider (at least briefly) on my transition to materials science. The feeling is mellowing, but the island experience taught me to think about my work with a mindset far different from the typical engineer or scientist. I learned to share the passion of others and to support my team in all endeavors of our project. This occasionally meant wearing waterproof high-waders in a stream when it was 104°C outside and 100 percent humidity, while lugging a massive backpack. Not typical aerospace or materials science work! Still, I cannot deny that it was one of the most enjoyable experiences in my whole education. I can, however, assure you that it also was one of the most valuable. I gained something intangible that just cannot be picked up in a classroom. When I went to Puerto Rico, I had already committed to the PhD program in materials science at Intelligent Processing of Materials Lab at the University of Virginia. This trip did not change my desire to work on gas turbines or to pursue my PhD. It did, however, change my outlook on my work. I started thinking about to whom my work was important, what other disciplines should or could be involved in my research, and how to communicate the value of the work to someone who does not have a PhD in materials science. And, at the risk of sounding cliché, reducing the environmental impact of gas turbines is now one of my primary interests in my research. Most importantly, I learned that we all are capable of far more diverse exercises than we believe. So, when you get the chance, do not pass up the opportunity to step far outside the box. You may find you are far more capable than you think. Brad Richards is a PhD candidate at the University of Virginia.

International Materials Institute for New Functionality in Jaime Neilson, IMI-NFG\'s first International REU student, at University of Cambridge. Glass By Karl W. Brisseaux (Credit: Jaime Neilson) (Credit: Seth Berbano) It has been a few years, but Seth st journey to Japan in the summer of 2009. The native Iowan had been outside of the United States before, but this was different. This time he spent 10 weeks in Japan, where he studied and conducted research at Osaka Prefecture University. \"I flew to Tokyo before arriving in Osaka, and on the way over the sun was setting. I looked down from the plane and I could see Mt. Fuji,\" says Berbano. “It was a honeymoon-like experience of Japan, an introduction to what was a mystical country to me.\" During the past eight years, the International Materials Institute for New Functionality in Glass (IMI-NFG) has offered Berbano and other students the opportunity to earn valuable experience through its Research Experience for Undergraduates (REU) program. The REU program offers domestic and international experiences: Participants have the opportunity to partake in glass research at Lehigh University and Pennsylvania State University, or at various research universities around the world. In total, the IMI-NFG has offered 15 individualized international experiences to undergraduate students in nine different countries. Berbano enjoyed his experience so much that he participated in another REU program in 2010 that sent him to Gyeonsang National University in South Korea. The experience helped prepare him for the rigors of earning a PhD in materials science and engineering at Penn State. Professors Himanshu Jain (Lehigh) and Carlo Pantano (Penn State) serve as the directors of the IMI-NFG. Bill Heffner, also of Lehigh, serves as associate director. Established in August 2004 through a National Science Foundation initiative, the IMI-NFG\'s global network of glass researchers spans 35 countries and is based at Lehigh in the Sinclair Laboratory. \"Our program is special in that it exposes the REU students to hands-on interdisciplinary research-they all work on glass, learn how to use it, and then approach specific problem with the aid of perspectives from professors of physics, electrical engineering, biology, or materials science,\" says Jain. James Neilson, one of the first alumni of the international REU program, echoes Jain\'s sentiments. He had the opportunity to travel to the University of Cambridge (UK) to interpret experimental data. “I learned how to teach myself something entirely unfamiliar. As an undergraduate engineering student, we are taught how to solve problems,\" recalls Neilson. \"This required an extensive amount of reading and independent self-education, a valuable skill that has gotten me to where I am today.\" Neilson, who graduated from Lehigh in 2006, will join the faculty at Colorado State University as an assistant professor of chemistry this fall. 34 www.ceramics.org | American Ceramic Society Bulletin, Vol. 92, No. 5 \"We also have educational outreach modules that facilitate interaction with historically minority colleges and universities,\" says Heffner. \"Besides international research opportunities, we also provide the opportunity for cross-disciplinary research for REU faculty advisers to work on glass.\" He notes IMI-NFG has successfully attracted faculty members who otherwise would have little opportunity to work with glass and allows them to propose exciting interdisciplinary undergraduate summer projects. Faculty from physics, electrical engineering, biomechanics, environmental engineering, and material science have participated. Since 2005, the program has offered more than 60 summer-term and 20 regular-term REU opportunities to students from more than 35 American universities in 17 states. The quality of research of most students is high. \"Many students have done outstanding work and gone on to publishing in top-class peer-reviewed journals,\" says Jain. For the domestic program, IMI-NFG selects eight to 10 students for work at Lehigh or Penn State each summer. International opportunities occur when a professor can make a connection with a colleague elsewhere in the world. In Berbano\'s case, his advisor, Steve Martin of Iowa State, helped him connect with Jain. \"Professor Martin thought that his connections could help me advance my research project and also advance my personal development by traveling abroad,\" says Berbano. The domestic REU also offers the opportunity for students from various research programs to interact and share experiences. For example, IMI-NFG joins with the REU program run by Lehigh\'s physics department for seminars, meals, social outings, and housing. IMI-NFG works to recruit students from various backgrounds and educational experiences. \"We find a great deal of value in bringing all these students from around the country, and putting them in an environment where they have to work together,\" says Heffner. \"We\'ve found that students really shine in this kind of environment.\" Heffner believes that the program has proved especially valuable to students like Mia Korngruen, a senior at Rowan University, who was intrigued by the opportunity to conduct materialsspecific research. \"REUS are pretty heavily advertised to sophomores and juniors at Rowan,\" rican ociety Mia Korngruen accepting first prize at the 2012 GOMD poster competition with John Balatto (left) and Morton Smedskjaer (right). says Korngruen, who is studying chemical engineering. \"I chose this one in particular because glass has always been fascinating to me.\" Under the guidance of Heffner and Andriy Kovalysky of Lehigh, Korngruen participated in the summer of 2011 in a project that she says taught her about background and literature-based research, experimental design, sample preparation, and data analysis. Starting with a model developed by Heffner, she created a conductivity meter and amplifier to study the effect of temperature and light on the conductivity of As₂S₁, a chalcogenide glass. Her project represented an innovative form of low-cost design for research. \"We used thermal evaporation to attach a thin film of the glass onto a substrate and then sputtered gold onto the thin film to create electrodes. \"Dr. Heffner explained that there would be an opportunity to do academic research, but it was structured for an underclassman that had no background in the subject. It was perfect for me,\" she adds. \"Mia is an example of a student who didn\'t have much lab experience, but ended up knocking it out of the park,” says Heffner. Korngruen was so successful, that she won first place in a poster competition at the 2012 ACerS\'s Glass & Optical Materials meeting. Beyond her research, Korngruen recalls that living with other students and collaborating with them in the American Ceramic Society Bulletin, Vol. 92, No. 5 | www.ceramics.org open, social atmosphere of the program helped her come out of her shell. \"There were about 30 of us in a sorority house and it was awesome,\" says Korngruen. Berbano says that the experience opened his eyes to the benefits of international collaborative research and broadened his cultural horizons. \"Travelling abroad really impacted how I feel about race and diversity issues,\" says Berbano. Neilson adds that his REU experience taught him “to think deeply about the root of problems and unknowns and how to go about solving them.\" Korngruen, who will work as a civilian engineer for the Navy after graduation, says that the experience gave her a unique insight into what graduate study and a career in academia would entail. And while she made the decision to pursue work in industry after completing her undergraduate studies, Korngruen enjoyed her research experience. Korngruen is not alone in gaining career insights via IMI-NFG\'s REU. “In our exit interviews, we have found that students really appreciate the opportunity to interact with other like-minded, technical people,” says Heffner. “The students get to learn about where peers are applying to graduate school and what research really is like, and it helps them decide whether graduate school or industry is right for them.\"[ 35 August 4-7, 2013 | Hilton Portland & Executive Towers | Portland, Ore. <<<<< 12th International Conference on Ceramic Processing Science (ICCPS-12) The American Ceramic Society www.ceramics.org ICCPS-12 has evolved from a focus on particle-based processes to including now thin-film processes, precursor approaches, and all facets of the science underlying the basic themes of control and tailoring of ceramic-based materials with specific microstructureproperty goals. ICCPS-12 marks the 27th anniversary of the ceramic processing science series. Since 1986, the discipline has made significant progress in colloid and surface chemistry, powder synthesis, precursor-derived systems, and sintering. However, much needs to be done to advance the scientific underpinnings of these processes as well as the emergent areas of nanotechnology and its associated challenges, particle assembly, patterning, additive manufacturing, rapid sintering, and densification of complex shapes and multimaterial combinations.
