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.

Harry Atwater and Colleagues Create Highly Absorbing, Flexible Solar Cells with Silicon Wire Arrays

02-23-10

Harry A. Atwater, Jr., Howard Hughes Professor and Professor of Applied Physics and Materials Science, and his colleagues have created highly absorbing, flexible solar cells with silicon wire arrays. "These solar cells have, for the first time, surpassed the conventional light-trapping limit for absorbing materials," says Professor Atwater. Furthermore this new type of flexible solar cell uses only a fraction of the expensive semiconductor materials required by conventional solar cells. [Caltech Press Release]

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."

Oskar Painter and Colleagues Propose Quantum Entanglement for Motion of Microscopic Objects

12-21-09

Oskar Painter, Associate Professor of Applied Physics, along with colleagues Darrick Change, Postdoctoral Scholar at Institute for Quantum Information, and H. Jeff Kimble, William L. Valentine Professor and Professor of Physics have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their idea offers a new means of studying the nature of quantum superposition and entanglement in progressively larger and more complex systems. [Caltech Press Release]
