Chancellor greets guests at inauguration of CaSTL center.

CaSTL center awarded $20 million from National Science Foundation.

"Super-resolution in coherent anti-Stokes Raman scattering microscopyEric Potma is supported by an award from the Experimental Physical Chemistry program to develop a coherent anti-Stokes Raman scattering (CARS) microscope with super-resolution. Development of this microscope will enable chemically selective imaging with a resolution down to the 50 nm length scale, opening up new areas in optical imaging of biological samples and engineered materials. The instrument will be used to study the nonlinear optical response of metallic nanowires, and to examine the distribution of sub-micrometer sized lipids droplets in breast cancer cells.

Congratulations to Ara Apkarian, who was elected a Foreign Member of the National Academy of Sciences of Armenia.

Rick Van Duyne was awarded the 2008 Ellis R. Lippincott Award by the American Optical Society (OSA).

Rick Van Duyne is the 2008 Professeur invite classe exceptionnelle University Pierre et Marie Curie, Paris.

The Potma group celebrates funding of an equipment grant proposal by the National Science Foundation. They will use this award to purchase a new laser system that will be interfaced with a focus-engineered CARS microscope.

Filipp Furche is the recipient of the "Outstanding Young German Scientist Award" for the year 2008, given by the Lise Meitner-Minerva Center for Computational Quantum Chemistry.

Filipp Furche is awarded a Lecturers Scholarship (Dozentenstipendium), by the German Chemical Industry Fund. The award is given to only four outstanding young chemists annually, and is for a duration of five years.

Congratulations to Ara Apkarian, who is the recipient of the 2008 ACS Charles R. Bennett Service Through Chemistry Award.

The Collins and Potma groups have shown that nonlinear signals can be induced from individual single walled carbon nanotubes (SWNT). By detecting the anti-Stokes shifted radiation, they managed to visualize primary electronic excitations in SWNTs using four-wave-mixing microscopy. Their work, which has implications for time-resolved single molecule experiments, recently appeared in Nano Letters.

Chemistry at the Space-Time Limit (CaSTL)

Student Desiré Whitmore at the Optricks Day 2007 Chemistry at the Space-Time Limit (CaSTL) is a Center for Chemical Innovation (CCI) at UCI, which is funded through the National Science Foundation, and administered through ISIS. The center is dedicated to the development of real-time experiments with atomistic resolution to probe the inner workings of molecules that characterize elementary events in chemistry and photophysics. These processes include: the oxidation and reduction of a single molecule, making and breaking of chemical bonds, charge transfer/transport, heterogeneous catalysis and videography of chemistry on the nanoscale. The capability to follow individual chemical events with atomistic resolution would usher a new perspective and mode of inquiry into molecular science and engineering. Indeed, for the purposes of instructing chemistry, it is hard to imagine a more incisive tool than the time-lapsed images of molecules undergoing chemical change, or responding to various external perturbations.
