Self-Contained, Photovoltaic Powered Domestic Toilet

08-15-12

Michael Robert Hoffmann, James Irvine Professor of Environmental Science, and his team of graduate students Asghar Aryanfar, Clement Cid, Kangwoo Cho, Daejung Kwon, and Hao Zhang, along with post doctoral scholar Yan Qu have won the Reinventing the Toilet Challenge issued by the Bill and Melinda Gates Foundation. Their winning proposal was to build a toilet that uses the sun to power an electrochemical reactor. The reactor breaks down water and human waste into fertilizer and hydrogen, which can be stored in hydrogen fuel cells as energy. The treated water can then be reused to flush the toilet or for irrigation. [Caltech Feature] [CNN Ideas]

Professor Kitaev Receives $3M Fundamental Physics Prize

07-31-12

Alexei Y. Kitaev, Professor of Theoretical Physics, Computer Science, and Mathematics, has received the $3 million Yuri Milner Fundamental Physics Prize. The prize citation recognizes Professor Kitaev's "theoretical idea of implementing robust quantum memories and fault-tolerant quantum computation using topological quantum phases with anyons and unpaired Majorana modes."  This new prize is the most lucrative academic prize in the world and Professor Kitaev is one of only nine scientists to receive it this year.

Chiara-daraio
Professor Daraio Wins Presidential Early Career Award

07-24-12

Chiara Daraio, Professor of Aeronautics and Applied Physics, has won a 2012 Presidential Early Career Award for Scientists and Engineers (PECASE). Daraio was recognized for her "pioneering contributions to nonlinear mechanical phenomena in acoustic crystals, granular material, and multifunctional nanostructures, and for mentoring women and providing research opportunities for high school and undergraduate students."

"The entire Caltech community is proud to see Professor Daraio recognized with this presidential honor, not only for her pioneering research accomplishments, but also for her commitment to students and diversity," says Chair Ares Rosakis. "Even though she is near the beginning of her career she already embodies the key attributes of the Division of Engineering and Applied Science at Caltech." [Caltech Release]

A Tissue-engineered Jellyfish with Biomimetic Propulsion

07-23-12

Graduate student Janna C. Nawroth, working with Professor John Dabiri and colleagues at Harvard, has turned solid element—silicon—and muscle cells into a freely swimming jellyfish.

"It is fascinating to witness the evolution of the Dabiri group's research from their initial ground-breaking work in understanding the fluid dynamics of jellyfish propulsion to the building of these complex engineered systems using biological materials," says Chair Ares Rosakis.

Students Work on Proposed Space Mission for Final Project

07-18-12

For the past few years, students in Professor Sergio Pellegrino's Aerospace Engineering course (Ae105), have helped design, prototype, and test various pieces of AAReST, a space-telescope demonstration mission currently under development. "It's really different from all of our other classes," says Aerospace graduate student Manan Arya. "You're actually doing work that's going to go into space. It's really exciting." [Caltech Feature]

Material's Spacing is Key to Brittle-to-ductile Transition

07-16-12

Julia R. Greer, her postdoctoral scholar Dr.Dongchan Jang, and colleagues have used experiments and atomistic simulations of nano-twinned metals (which have the unique combined effect of being strong and ductile) to decipher the specific role of the twin boundaries. They have found that it is the spacing between the twin boundaries that determines whether a material is brittle or ductile as opposed to the sample size, as would be expected. Greer states "this is probably the first study that truly isolated the twin boundaries by making samples which contained only twin boundaries, periodically spaced throughout the sample, and then tested them in tension. This understanding will help in the design of better structural materials and provide a certain amount of predictability in doing so, which has not been possible to date."
