Sears writes in an email. “And it’s refreshing to see so many architects and designers using brick in a range of color palettes and architectural styles. Brick truly stands up to the latest trends—from historic landmarks in classic red to cutting-edge innovations in vibrant color schemes.”

The contest rules on the BIA’s website state that entrants can submit architectural work completed within the last five years, in which new clay bricks comprise more than half of the exterior building or paving material.

Graphene foam could be just the prescription for arthritis sufferers New research from scientists at Boise State University sug- gests graphene foam soon could play a crucial role in joint replacement and treatment of osteoarthritis pain. Led by Ph.D. student in the Micron School of Materials Science and Engineering, Katie Yocham, and codirector of the Boise State University’s Advanced Nanomaterials and Manufacturing Laboratory, David Estrada, researchers mixed graphene foam with animal cells (ATDC5) to build bioscaf- folds to replace cartilage destroyed by osteoarthritis, according to a Boise State news release. “In tissue engineering, graphene represents a unique mate- rial with structure property processing correlations that can be used to design bioscaffolds to communicate electrically and mechanically with adhered stem cells, driving their differentia- tion down various pathways,” Estrada adds in the article. Estrada writes in an email that chemical exfoliation is an area they plan to study. “Graphene can be synthesized by chemical exfoliation, via chemical vapor deposition, and subli- mation of Si from SiC surfaces,” he explains. “This results in very different structure–property–processing correlations and our preliminary data shows this has a significant impact on the performance of graphene as a bioscaffold.” According to the Centers for Disease Control and Prevention, an estimated 54.4 million adults in the U.S. suffer from arthritis. Over 30 million U.S. adults have been diag- nosed with osteoarthritis, the most common form. The paper, published in Advanced Engineering Materials, is “Mechanical Properties of Graphene Foam and Graphene Foam—Tissue Composites” (DOI: 10.1002/adem.201800166). n

A major manufacturing and application challenge in ceram- ics is the characteristically low toughness. Although composites are known to improve toughness of ceramics, single-phased ceramics with high toughness are desirable, but not easily attainable, given that many functional properties, such as opti- cal, are based on monolithic products. It was proposed that grain size reduction would improve WASHINGTONMILLS.COM toughness by allowing grains to slide against each other, 716.278.6600 • 800.828.1666 • [email protected] much like woven polymers absorb impacts. However, most nanoceramics do not show the predicted high toughness, because grain–grain interfaces show much higher friction than expected, and so defects cannot move easily along boundaries, leading to facile crack propagation. A team of researchers from University of California, Davis, in collaboration with researchers from University of Illinois at Urbana-Champaign, have explored the weak interfaces in nanoceramics to demonstrate a new toughening mechanism for nanoceramics. In fibrous composites, fibers create an alternative crack path that deflects cracks and improves toughness. In nanocrystalline ceramics, the U.C. Davis team proposed that the extensive grain boundary network is a dormant crack path waiting to be awakened. In other words, there are many grain boundary pos- sibilities for cracks to propagate. However, cracks typically go in one direction and are mostly linear, which lowers toughness. This is because grain bound- aries are not all equal in crystalline materials. Some grain boundaries are weaker than others and hence, cracks mostly propagate through those that are easier to break, resulting in clean and linear cracks. It stands to reason, then, that eliminat- ing disparity in grain boundary strength would remove a “path of least resistance” and lead to a more distributed or tortuous crack path, as shown in the image above. The team designed a way for all of the grain boundaries to be more alike. By using dopants that segregate to the grain boundaries, researchers showed they can reduce local energies and improve toughness of individual boundaries. However, more importantly, the researchers acknowledged the existence of weak as well as already strong boundaries. Therefore, they target the weakest grain boundaries primarily so they can be made as

hybrid electric Chevy Volts driven in winter in Chicago had 29% less range than those driven in spring in Chicago. Chao-Yang Wang and his team developed a self-heating lithium battery that uses thin nickel foil with one end attached to the negative terminal and the other end extending outside the battery, creating a third terminal. Wang is William E. Dief- enderfer Chair of mechanical engineering, professor of chemi- cal engineering, professor of materials science and engineering, and director of the Electrochemical Engine Center at Pennsyl- vania State University. The foil serves as a heater of sorts. A temperature sensor sets off electron flow through the foil—heating it up and warming the battery. The sensor switches off after the battery reaches 32°F, allowing electric current to continue flowing normally. Wang and his team have taken their technology a step fur- ther by enabling the battery to charge itself in 15 minutes at temperatures as low as –45°F. When the battery’s internal temperature reaches room tem- perature and above, the switch opens to allow electric current to flow in and quickly charge the battery. “One unique feature of our cell is that it will do the heating and then switch to charging automatically,” Wang explains in

The most prestigious of ACerS awards is designation as a Distinguished Life Member, a recognition bestowed upon only two or three members each year. In 2018, three individuals will receive DLM honors: Amar Bhalla, John Halloran, and George Scherer. The Society will elevate 15 members to Fellow and recognize many more outstanding members with various Society, Division, and Class awards and lectures that will be presented at ACerS Annual Awards Banquet at MS&T18, October 14–18, in Columbus, Ohio.

However, efficiency by itself is not enough to truly compete with continuous or large batch processes for traditional ceramics. The true promise is the ability to reliably and reproducibly fabricate materials with unique nano/microstructures and metastable phase content, i.e., for making materials that are difficult to make by more conventional techniques. Current-activated pressure-assisted sintering shows promise Here we briefly discuss our ongoing efforts using CAPAD to make for densifying novel, transparent optical oxides. ceramics for useable, novel optical devices at the Advanced Materials Processing and Synthesis Lab at University of California, San Diego (UCSD). Specifically, we give examples of optical amplitude modula- tors and laser gain media made from CAPAD fabricated polycrystal- line oxides. One of the benefits of functional optical ceramics is that typical sizes of CAPAD fabricated materials are large enough to be used directly in optical devices. Figure 1 shows the CAPAD machine that we use at the UCSD. For many structural applications, a press- ing need exists for producing ever larger parts. CAPAD has no fun-

It did not take long for the community to realize the picture is more complicated (see diagram). Nanoparticles are highly reactive and absorb all sorts of molecules on their surfaces to reduce the excess energies coming from unsatisfied chemical bonds and bonding coordination.

Molecules such as H2O, CO2, SO4, and other chemicals commonly found in the synthetic environment reduce the surface energy, hence the driving force for densification. In addition to negatively acting on the thermodynamics of the process, those chemicals will be released during sintering in the form of gases, causing residual porosities that are generally difficult to remove. Although one could use such
