Professor Minnich Receives IPPA Junior Prize


Austin Minnich, Professor of Mechanical Engineering and Applied Physics, is a recipient of the International Photothermal and Photoacoustics Association (IPPA) Junior Prize. He received the prize for outstanding contributions to the understanding of quasiballistic thermal transport, including the development of photothermal methods to directly probe heat conduction at length scales comparable to phonon mean free paths; for demonstrating how microscopic transport properties of thermal phonons in solids may be obtained using photothermal experimental methods along with ab-initio calculations; and for advances in the mathematical treatment of quasiballistic transport using the Boltzmann equation.

Reflective Nanostructures


Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, and colleagues have discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark. The new technology uses surfaces covered by a metamaterial consisting of millions of silicon pillars, each only a few hundred nanometers tall. By adjusting the size of the pillars and the spacing between them, Faraon can manipulate how the surface reflects, refracts, or transmits light. [Caltech story]

Grad Student Makes Ultra-Sensitive Measurement of Deformation


Xiaoyue Ni, a materials science graduate student working with Professor Julia Greer, has shown that metals undergo permanent deformation even prior to yielding—the threshold at which a material under strain becomes permanently deformed. "What Xiaoyue's data are showing is that from the first moment you start deforming it, the dislocations start being active," Greer says. Now that we know how to do this, we can probe a variety of different classes of materials. [Caltech story]

A Rainbow of Possibilities


Professor Andrei Faraon, graduate student Ehsan Arbabi, and their colleagues have developed a metasurface or a sheet of material that can be altered on demand to exhibit properties not usually found in natural materials. For example, materials engineered at the nanoscale can control the dispersion of light and could be the basis of next-generation spectrometers and other imaging devices. [Caltech story]

2017 Library Thesis Prize


Senior Daniel Lim has received the 2017 Library Friends' Senior Thesis Prize for his work on sculpting nanofilms with laser illumination. Lim's thesis, titled "Revolution in large-area curved surface lithography: Nanofilm sculpting by thermocapillary modulation," is based on experimental research he conducted over two years in the laboratory of Professor of Applied Physics, Aeronautics, and Mechanical Engineering Sandra M. Troian. "Our group has been working on thermocapillary sculpting of nanofilms for several years now,” says Troian. "Daniel advanced this concept by demonstrating an inverse projection method, which imbues the sculpting process with far greater versatility. Daniel is an exceptional student—a rare combination of superb talent, tremendous drive, utmost professionalism, and entrepreneurial chops. " [Caltech story]
