Using DNA to Manufacture Nanoscale Devices

11-16-11

William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics, has received $1.25 million from the National Science Foundation (NSF) to develop a process that takes advantage of DNA's talent for self-assembly to arrange nanomaterials such as carbon nanotubes and proteins into configurations designed for use in devices such as sensors, transistors, and optical components.

An Incredible Shrinking Material

11-07-11

Graduate student, Chen Li, and colleagues including Brent Fultz,  Professor of Materials Science and Applied Physics, have shown how scandium trifluoride (ScF3) contracts with heat.  "A pure quartic oscillator is a lot of fun," Professor Fultz says. "Now that we've found a case that's very pure, I think we know where to look for it in many other materials." Understanding quartic oscillator behavior will help engineers design materials with unusual thermal properties. "In my opinion," Fultz says, "that will be the biggest long-term impact of this work."

New Institute for Quantum Information and Matter

10-14-11

Caltech has been awarded $12.6 million in funding by the National Science Foundation to create the Institute for Quantum Information and Matter (IQIM), the center will bring physicists and computer scientists together to push theoretical and experimental boundaries in the study of exotic quantum states.  The co-directors of this institute are Professors Jeff Kimble, Jim Eisenstein, Oskar Painter, and John Preskill. "When you bring innovative scientists and engineers together and provide them with the facilities and collaborative spaces they need, magic happens. The magic involves transforming the way we think about and impact our world," says EAS Chair Ares Rosakis. [Caltech Press Release]

Fueling Fundamental Research

10-13-11

To strengthen fundamental science and technology and foster transformational advances in renewable energies, the Dow Chemical Company and Caltech have established a $10 million partnership. Under the partnership, Dow will provide ongoing support for graduate student research through endowed fellowships which include five in energy science. The Resnick Sustainability Institute is receiving a significant portion of the funding in the agreement. Through the new Dow Chemical Company Bridge/CI2 Innovation Program, financial support will be used to further promising graduate and postdoc research that has the possibility of creating licensable technologies and start-ups. The graduate research fellowships in energy—renewable for up to two years—will help advance clean-energy goals. [Caltech Press Release]

Using Laser Light to Cool Object to Quantum Ground State

10-07-11

Oskar J. Painter, Professor of Applied Physics and Executive Officer for Applied Physics and Materials Science, and colleagues including graduate student Jasper Chan have cooled a miniature mechanical object—a tiny mechanical silicon beam— to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors. "In many ways, the experiment we've done provides a starting point for the really interesting quantum-mechanical experiments one wants to do," Painter says. [Caltech Press Release]

Nano-mechanics of Carbon Nanotube Research Wins Art Competition

08-22-11

Siddhartha (Sid) Pathak, a W. M. Keck Institute for Space Studies (KISS) Postdoctoral Fellow in Material Science, has received the first prize in the NanoArt 2011 International Competition. The inspiration for Dr. Pathak's entry entitled "In-situ SEM deformation of CNT micro-pillars" is his research on nano-mechanics of carbon nanotubes.  As a KISS postdoc Dr. Pathak is working with  Professor Julia Greer on mechanical testing of carbon nanotubes at submicron length scales, with a particular emphasis towards space applications.
