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.

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.

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."

DNA Origami Nanoscale Breadboards for Carbon Nanotube Circuits

11-10-09

Hareem T. Maune, a graduate student studying carbon nanotube physics, and Si-ping Han, a graduate student investigating the interactions between carbon nanotubes and DNA have developed DNA origami nanoscale breadboards for carbon nanotube circuits. "This collaborative research project is evidence of how we at Caltech select the top students in science and engineering and place them in an environment where their creativity and imagination can thrive," says Ares Rosakis, chair of the Division of Engineering and Applied Science at Caltech and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. The work of these students was supervised by: Erik Winfree, Associate Professor of Computer Science, Computation and Neural Systems, and Bioengineering; William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; Paul W.K. Rothemund, Senior Research Associate, and Marc Bockrath, Associate Professor of Physics at University of California Riverside. [Caltech Press Release]
