Professor Clauser Passes Away

03-05-13

Francis H. Clauser, Clark Blanchard Millikan Professor of Engineering, Emeritus, passed away on Sunday, March 3, at 99 years of age. Professor Clauser, a Caltech alumnus (PhD '37), served as Chair of the Division of Engineering and Applied Science from 1969 to 1974. Upon stepping down as Chair he remained the Millikan Professor until his retirement. Although he retired in 1980, he maintained a vital presence on the Caltech campus, particularly at the Athenaeum round table, until shortly before he passed. [Caltech Release]

EAS Division Welcomes New Deputy Chair

02-08-13

Peter Schröder, Professor of Computer Science and Applied and Computational Mathematics, is the new Deputy Chair of the Division of Engineering and Applied Science. "I look forward to working with Peter over the next several years as we continue with our quest to remain a unique collaborative community of isolated singularities that sets a compelling model as a research and teaching institution," says Chair Ares Rosakis.

Clean-Energy Research Accelerates

10-22-12

Caltech clean-energy research is accelerating thanks to the renovation of the Earle M. Jorgensen Laboratory. Transformed into a cutting-edge facility for energy science, the lab unites two powerhouse programs: the Resnick Sustainability Institute and the Joint Center for Artificial Photosynthesis (JCAP). "Our researchers are working with Caltech's chemists and chemical engineers to challenge the status quo and translate scientific discovery into clean-energy innovations that will directly benefit society for generations to come," says Chair Ares Rosakis.

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]

New Insight into Acid Rain Chemistry

06-13-12

A multidisciplinary team led by Dr. A. J. Colussi, comprising of graduate student Himanshu Mishra, and Professor Michael Hoffmann along with Dr. Robert J. Nielsen and Professor William A. Goddard III from the Materials and Process Simulation Center, has shown that the dissociation of nitric acid on thin layers of water, such as those in contact with air or biological membranes, is dramatically different from the similar process inside water. They have found that the molecules of nitric acid do not dissociate when they collide with water unless its surface contains at least 1 anion per million water. This work explains how minute concentrations of anions might subtly participate in acid rain chemistry, the cycling of nitrogen oxide pollutants on urban haze, and in the charging of protein surfaces that drive enzyme activities.

Using Stalagmites to Study Past Climate Change

05-04-12

By analyzing stalagmites, Jess F. Adkins, Professor of Geochemistry and Global Environmental Science, and colleagues have determined that the climate signature in the tropics through four glacial cycles looks different in some ways and similar in others when compared to the climate signature at high latitudes. The results suggest that Earth's climate system might have two modes of responding to significant changes. [Caltech Press Release]

New Computer Model Explains Lakes and Storms on Titan

01-05-12

A new computer model of the atmosphere and methane cycle of Titan, Saturn's largest moon, explains baffling observations of its lakes and storms. "We have a unified explanation for many of the observed features," says Tapio Schneider, the Frank J. Gilloon Professor of Environmental Science and Engineering. "It doesn't require cryovolcanoes or anything esoteric." [Caltech Press Release]
