The Center for the Science and Engineering of Materials
(CSEM), established in September of 2000, addresses both
research and educational aspects of polymeric, structural,
photonic, and ferroelectric materials that will be necessary
to solve critical societal needs of the twenty-first century.
The Center pioneers a number of exotic and futuristic materials
and applications such as liquid metals, responsive gels,
and tiny medical sensors.

Solar Fuels – Thermochemical Processes & Reactor Technology
Aldo Steinfeld, ETH Zurich and Paul Scherrer Institute, Switzerland
Wednesday, January 14th
2:00 pm in Keck 142
Solar thermochemical processes for the production of hydrogen, syngas, metals, and other synthetic fuels and materials make use of concentrated solar radiation as the energy source of high-temperature process heat. Considered are water-splitting thermochemical cycles based on metal oxide redox reactions at 2000 K, and reforming / gasification / decomposition processes for the thermal decarbonization of fossil fuels at 1500 K. R&D work encompasses fundamental studies on thermodynamics, reaction kinetics, heat/mass transfer, and chemical reactor engineering. Solar reactor prototypes are designed, fabricated, modeled, and tested in a high-flux solar furnace, further optimized for maximum solar-to-chemical energy conversion efficiency, and finally scaled-up for (MW) industrial applications using concentrating solar tower technology.
Caltech faculty associate Jeff Synder and colleagues have invented a new material that will make cars even more efficient by converting heat lost through engine exhaust into electricity. In a paper published July 25, 2008 in the journal Science, the scientists describe the unique thermoelectric material, which has twice the efficiency other such materials currently on the market, and works most effectively in the temperature range typical of automobile engines. The same technology could also work in power generators and heat pumps. Read more at www.sciencemag.org.
CSEM has
received a $350,000 grant from the National Science Foundation and a
semiconductor industry consortium on nanoelectronics to conduct work
on a novel material--graphenes. Over three years, the grant will
fund a project intended to take the field beyond the Moore's Law
regime and utilize new architecture concepts. The grant recipients
are Marc Bockrath, Assistant Professor
of Applied Physics, Nai-Chang
Yeh, Professor of Physics, and Shuki
Bruck, the
Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical
Engineering.
The
AT&T Tech Channel discusses Plasmonics with Harry
Atwater, Howard Hughes Professor and Professor of Applied
Physics and Materials Science. New research in Plasmonics
promises breakthroughs with implications ranging from the
creation of faster than light computing, possible new weapons
against cancer, and maybe even achieving invisibility.

In
the online journal Science Express, Caltech applied physicists
Harry Atwater,
Henri Lezec, and Jen Dionne report that they have devised
a way to make visible light travel in the opposite direction
that it normally bends when passing from one material to
another, like from air through water or glass. This could
lead to "cloaking devices" that
may render an object invisible.
