Postdoctoral Scholar Receives Dissertation Award From American Physical Society

12-10-14

Moureen C. Kemei, Resnick Sustainability Institute Prize Postdoctoral Scholar in Applied Physics & Materials Science, has recieved the American Physical Society's Richard L. Green Dissertation Award in Experimental Condensed Matter or Condensed Matter Physics. The award recognizes her outstanding thesis on "Magnetostructural and Magnetodielectric Coupling in Spinel Oxides" citing her achievement in employing advanced characterization tools to gain new insights into the structure and electronic properties of magnetic materials and solid oxide fuel cell (SOFC) cathode materials. The exploration of SOFC cathode materials is the focus of Moureen’s research at the Resnick Sustianability Institute, which she works on in the lab of Professor Sossina Haile.

New Technique Could Harvest More of the Sun's Energy

11-26-14

Harry A. Atwater, Jr., Howard Hughes Professor of Applied Physics and Materials Science as well as Director of the Resnick Sustainability Institute, and colleagues have created a new technique to harness the lost energy from solar panels. “Silicon absorbs only a certain fraction of the spectrum, and it's transparent to the rest. If I put a photovoltaic module on my roof, the silicon absorbs that portion of the spectrum, and some of that light gets converted into power. But the rest of it ends up just heating up my roof," explains Professor Atwater. Now they have found a way to absorb and make use of these infrared waves with a structure composed not of silicon, but entirely of metal. [Caltech story]

Heat Transfer Sets the Noise Floor for Ultrasensitive Electronics

11-10-14

Austin Minnich, Assistant Professor of Mechanical Engineering and Applied Physics, and colleagues have identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes and advanced physics experiments. The team's findings also suggest that it may be possible to develop engineering strategies to make phonon heat transfer more efficient at low temperatures. For example, one possibility might be to change the design of transistors so that phonon generation takes place over a broader volume. "If you can make the phonon generation more spread out, then in principle you could reduce the temperature rise that occurs," Professor Minnich says. "We don't know what the precise strategy will be yet, but now we know the direction we should be going. That's an improvement." [Caltech release]

Making Hotter Engines and Lasting Artwork

11-07-14

Katherine Faber, Simon Ramo Professor of Materials Science, studies the reasons why brittle ceramics fracture—and how these materials can be made stronger and tougher in the future. Her research interests have also been applied to sustainability and the arts. [Interview with Professor Faber] [ENGenious article]

Ceramics Don't Have To Be Brittle

09-11-14

Julia R. Greer, Professor of Materials Science and Mechanics, and her colleagues are on the path to developing materials that possess unheard-of combinations of properties. "Ceramics have always been thought to be heavy and brittle," says Professor Greer. "We're showing that in fact, they don't have to be either. This very clearly demonstrates that if you use the concept of the nanoscale to create structures and then use those nanostructures like LEGO to construct larger materials, you can obtain nearly any set of properties you want. You can create materials by design." [Caltech Release]
