Observations Reshape Basic Plasma Wave Physics

04-06-17

Paul M. Bellan, Professor of Applied Physics , and colleagues have discovered a new way to determine the wavelength of energy flowing through plasma in space—a method that was recently applied during a NASA mission that yielded the first solid evidence of how energy sloshes back and forth in a magnetic wave that moves through the plasma surrounding the earth.

New Materials Could Turn Water into the Fuel of the Future

03-06-17

Researchers at Caltech and Lawrence Berkeley National Laboratory have—in just two years—nearly doubled the number of materials known to have potential for use in solar fuels. "The key advance made by the team was to combine the best capabilities enabled by theory and supercomputers with novel high throughput experiments to generate scientific knowledge at an unprecedented rate," says John Gregoire, JCAP thrust coordinator for Photoelectrocatalysis and leader of the High Throughput Experimentation group.

Engineers Create Artificial Skin That "Feels" Temperature Changes

01-30-17

Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed an artificial skin capable of detecting temperature changes using a mechanism similar to the one used by the organ that allows pit vipers to sense their prey. [Caltech story]

Tools and Techniques to Track and Study Methane

01-19-17

Methane is less prevalent in the atmosphere than fellow greenhouse gas carbon dioxide (CO2), but it presents more difficult challenges for researchers attempting to study it. Professor Wennberg, is working with colleagues from across Caltech to study methane and its effects on the globe and to pioneer tools and techniques needed to identify, track, and characterize the gas and its sources. One such colleague is Professor Vahala who has paved the way for the miniaturization of high-resolution spectrometers. His new soliton-based system is the basis for a new collaboration with Professor Frankenberg to apply dual-comb spectrometer to methane tracking and analysis. [Caltech story]

Professor Johnson Elected to National Academy of Inventors

12-13-16

William L. Johnson, Ruben F. and Donna Mettler Professor of Engineering and Applied Science, has been named fellow of the National Academy of Inventors (NAI). His research includes early pioneering work with metallic materials such as bulk metallic glasses, non-crystalline metals with an amorphous atomic structure and unusual engineering properties. Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."

Professor Yariv Elected to National Academy of Inventors

12-13-16

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering , has been named fellow of the National Academy of Inventors (NAI). His research has focused on creating the mathematical tools and building blocks underpinning guided wave optics, the backbone of today's optoelectronic technologies. This endeavor led to the proposal and demonstration of the distributed feedback laser and started the field of optoelectronic integrated circuits. Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."

Raising Temperature Changes an Element's Electronic "Topology"

10-27-16

Brent Fultz, Barbara and Stanley R. Rawn, Jr., Professor of Materials Science and Applied Physics, and colleagues have discovered a new way that heat tweaks the physical properties of a material. The potential value to engineers lies in the fact that it is much easier to raise the temperature of a material than it is to place it under the sort of pressure needed to force an electronic topological transition.
