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]
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]
Hyuck Choo, Dennis Kochmann, and Austin Minnich focus on quite different challenges, but they all home in on the nanoscale. "Caltech and EAS take pride in lowering the barriers between disciplines to create collaborative environments for researchers such as Hyuck, Dennis, and Austin to work on a variety of topics including understanding and predicting behavior of materials at the nanoscale, which already is an area of strength within EAS," says Ares Rosakis, Theodore von Karman Professor of Aeronautics and Professor of Mechanical Engineering; Chair, Division of Engineering and Applied Science.

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.

Julia R. Greer, Assistant Professor of Materials Science and Mechanics, has been selected by the American Society of Mechanical Engineers (ASME) Materials Division Executive Committee to receive the 2011 Sia Nemat-Nasser Early Career Award for her research contributions in “physical origins of size-dependent mechanical properties in nano-scale solids”.
Mani Chandy, Simon Ramo Professor and Professor of Computer Science; Deputy Chair for Education, and Julian J. Bunn, Principal Computational Scientist at CACR, are working with a group of Summer Undergraduate Research Fellowships (SURF) in CMS, EE, and MCE to building a collection of medical devices that can be connected to a cell phone. "We want to exploit cell-phone technology and the Internet to provide inexpensive health-care tests for the poor in remote rural villages," says Chandy. [Caltech Feature]
Joel W. Burdick, Professor of Mechanical Engineering and Bioengineering, and colleagues including Yu-Chong Tai, Professor of Electrical Engineering and Mechanical Engineering, have used a stimulating electrode array to assist a paralyzed man to stand, step on a treadmill with assistance, and, over time, to regain voluntary movements of his limbs. Using a combination of experimentation, computational models of the array and spinal cord, and machine-learning algorithms, Professor Burdick and his colleagues are now trying to optimize the stimulation pattern to achieve the best effects, and to improve the design of the electrode array. Further advances in the technology should lead to better control of the stepping and standing processes. [Caltech Press Release]
Julia R. Greer, Assistant Professor of Materials Science and Mechanics, has received a five-year award from the Department of Energy Office of Science's Early Career Research Program for her proposal entitled “Investigation of radiation damage tolerance in interface‐containing metallic nano structures”. These research awards provide incentives for exceptional researchers, during the crucial early career years, to focus on research areas that are a high priority for the Department of Energy and the Nation.
