Julia R. Greer, Assistant Professor of Materials Science and Mechanics, is receiving a 2012 Breakthrough Award from Popular Mechanics magazine as part of the team that engineered the world's lightest solid material. "I am delighted that Professor Greer is being honored with this award," says Ares Rosakis, chair of the Division of Engineering and Applied Science (EAS) at Caltech. "She is a great example of how we in EAS are working at the edges of fundamental science to invent the technologies of the future." [Caltech Release]

Julia R. Greer, her postdoctoral scholar Dr.Dongchan Jang, and colleagues have used experiments and atomistic simulations of nano-twinned metals (which have the unique combined effect of being strong and ductile) to decipher the specific role of the twin boundaries. They have found that it is the spacing between the twin boundaries that determines whether a material is brittle or ductile as opposed to the sample size, as would be expected. Greer states "this is probably the first study that truly isolated the twin boundaries by making samples which contained only twin boundaries, periodically spaced throughout the sample, and then tested them in tension. This understanding will help in the design of better structural materials and provide a certain amount of predictability in doing so, which has not been possible to date."

The student winners of the 2012 Demetriades - Tsafka - Kokkalis Prizes were announced at a special luncheon with the Demetriades - Tsafka – Kokkalis family. Philip Romero received the prize in Biotechnology for his work on developing statistical models of proteins with Frances Arnold. Michael Mello was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Ares Rosakis on developing a novel methodology for identifying the unique ground motion signatures of supershear earthquakes. Leslie O’Leary received the prize in Environmentally Benign Renewable Energy Sources for her pathbreaking work on the properties of semiconductor interfaces with Nate Lewis and Bob Grubbs. This year there were two winners for the prize in Nanotechnology. One winner was Andrew Jennings for his experimental and modeling work in nanomechanics with Julia Greer. The other winner of the Nanotechnology prize was Jordan Raney who has worked with Chiara Daraio to develop new chemical synthesis methods to control the properties of carbon nanotubes.

Kaushik Bhattacharya, Howell N. Tyson, Sr., Professor of Mechanics and Professor of Materials Science, is the Caltech lead on a $90 million U.S. Army Research Laboratory funded program to improve protective gear and vehicles for soldiers. "…studying materials in very extreme conditions is an area where Caltech engineering really stand out," says Bhattacharya. "The tools we bring, on both the theoretical and experimental sides uniquely bridge deep fundamental principles with unprecedented application.” [Caltech Feature]

Julia R. Greer, Assistant Professor of Materials Science and Mechanics, and colleagues have developed the world’s lightest solid material, with a density of 0.9 milligrams per cubic centimeter. The new material, called a micro-lattice, relies, on a lattice architecture: tiny hollow tubes made of nickel-phosphorous are angled to connect at nodes, forming repeating, asterisklike unit cells in three dimensions. "We're entering a new era of materials science where material properties are determined not only by the microscopic makeup of the material but also by the architecture of the constituents," Greer says.

Siddhartha (Sid) Pathak, a W. M. Keck Institute for Space Studies (KISS) Postdoctoral Fellow in Material Science, has received the first prize in the NanoArt 2011 International Competition. The inspiration for Dr. Pathak's entry entitled "In-situ SEM deformation of CNT micro-pillars" is his research on nano-mechanics of carbon nanotubes. As a KISS postdoc Dr. Pathak is working with Professor Julia Greer on mechanical testing of carbon nanotubes at submicron length scales, with a particular emphasis towards space applications.
