How an Idea Becomes a Business

03-29-11

Students in Ken Pickar's course Entrepreneurial Development (E 102) have the opportunity to identify a technology currently under study at Caltech and develop a business plan for it. The ideas used by the students this year included a solid-state memory technology developed by Jehoshua (Shuki) Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering. In this business plan the students proposed targeting Netflix and other high-volume streaming content providers. Another team pinpointed a new market for the vertical wind turbines of John O. Dabiri, Professor of Aeronautics and Bioengineering. A third team pitched a noninvasive method for breaking up arterial plaques using the concentrated-acoustic-pulse technology developed by Chiara Daraio, Professor of Aeronautics and Applied Physics.

New Reactor Paves the Way for Efficiently Producing Fuel from Sunlight

01-20-11

Sossina Haile, Professor of Materials Science and Chemical Engineering, and colleagues have built a reactor at the heart of which is a cylindrical lining of ceria—a metal oxide. The reactor takes advantage of ceria's ability to "exhale" oxygen from its crystalline framework at very high temperatures and then "inhale" oxygen back in at lower temperatures - concentrating solar energy in order to convert carbon dioxide and water into fuels .  Ultimately, Haile says, the process could be adopted in large-scale energy plants, allowing solar-derived power to be reliably available during the day and night. [Caltech Press Release]

Amnon Yariv Awarded National Medal of Science

10-15-10

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, has received one of the highest honors bestowed by the United States government on scientists, and engineers. He is a recipient of the National Medal of Science. Professor Yariv's research group has pioneered the field of optoelectronics. Many innovations such as distributed Feedback (DFB) Semiconductor Lasers, Integrated Optoelectronic Circuits, Optical Phase Conjugation, External Cavity Tunable Semiconductor Lasers, Quantum Well Infrared Photodetectors (QWIP's), and all-fiber add/drop filters have found their beginnings in his research group. Currently, his group’s research aims at developing the new technologies that will be mandated by the seemingly endless appetite for optical bandwidth. Specifically, they are working at extending, to the field of laser optics, some key ideas that form the foundation of the microwaves and the radio frequencies fields.

Novel Negative-Index Metamaterial that Responds to Visible Light

04-23-10

Stanley Burgos, researcher at the Light-Material Interactions in Energy Conversion Energy Frontier Research Center, Harry A. Atwater, Jr., Howard Hughes Professor and Professor of Applied Physics and Materials Science, and colleagues have engineered a novel negative-index metamaterial that responds to visible light. This material bends light in the "wrong" direction from what normally would be expected, irrespective of the angle of the approaching light. [Caltech Press Release]

Caltech Researchers Create "Sound Bullets"

04-22-10

Alessandro Spadoni, Postdoctoral Scholar, and Chiara Daraio, Assistant Professor of Aeronautics and Applied Physics, have built a nonlinear acoustic lens that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." The combination of the acoustic lens and sound bullets have "the potential to revolutionize applications from medical imaging and therapy to the nondestructive evaluation of materials and engineering systems," says Professor Daraio.

Nanoscale Structures with Superior Mechanical Properties

02-09-10

Julia Greer, Assistant Professor of Materials Science and Mechanical Engineering, and Dongchan Jang, Postdoctoral Scholar, have developed a way to make some notoriously brittle materials ductile—yet stronger than ever—simply by reducing their size. Professor Greer describes, "We are entering a new era in materials science, where structural materials can be created not only by utilizing monolith structures, like ceramics and metals, but also by introducing 'architectural' features into them."
