MICS thanks the Department of Chemistry and Biochemistry for funding!
Want feedback on a technique that you haven't necessarily perfected yet?
Interested in learning more about the chemistry your fellow gradute students and post docs do?
MICS is organized by and for graduate students and post docs.
MICS features bi-weekly speakers from different programs at the University of Colorado, Boulder, as well as surrounding govermnet labratories, NOAA, NCAR, NIST and NREL. Seminars have plenty of time for discussion, as well as refreshments, all in a relaxed environment. Presenters are encouraged to focus on the methods and techniques used in their research.
Talks are limited to 20 to 40 minutes in length, so that, including questions and discussion, the seminar is limited to about an hour. They should focus on methods and techniques (experimental or theoretical), and be geared towards an interdivisional audience. The MICS was conceived as a way for graduate students and post docs to learn about the variety of research being done in our department and other science departments, such as physics, biology, engineering. In an effort to encourage questions and discussion, and to keep things fun and informative, the seminar is expressly by and for graduate students and post docs.
WHEN: Wednesdays at 12:00 p.m.
WHERE: CIRES S274
THIS WEEK October 8, 2008:
Speaker: Danny Bell (Nesbitt Lab)
The Talk: Velocity Map Imaging: Taking a Look into Gas-Phase Reaction Dynamics
The Abstract:
Imaging techniques, which emerged about 20 years ago in the chemical physics community, allow for mass- and quantum-state specific measurement of both the recoil velocities and the angular distribution of reaction products. Any particle that can be ionized is a candidate for detection, and applications span a wide spectrum of systems, from simple unimolecular photodissociation to polyatom-polyatom gas-phase reactions. More recently, refinements in technology (CCDs) and the advent of the Velocity Map Imaging method have increased sensitivity and velocity resolution (<0.1%) in modern experiments, allowing new insight into the details of how molecules react with each other. Important experimental methods presented include Resonance Enhanced Multi-Photon Ionization (REMPI), electrostatic lensing, Micro-Channel Plate (MCP) detectors and supersonic expansions.
Speaker: Carolynn Chin (Sammakia Lab)
The Talk:
The Blonde, the Brunette, or the Redhead: Selectivity in Cross Metathesis with Polyolefins
The Abstract:
Carbon-carbon bond formation is at the heart of synthetic organic chemistry, and new methods to form carbon-carbon bonds are highly sought after. One significant advance in this area that has recently seen a substantial increase in application is olefin metathesis, which is the exchange of ends between two alkenes. Olefin cross metathesis (the intermolecular metathesis reaction involving two different alkenes) is of particular significance because it serves as a convenient route to functionalized and higher olefins from simple alkene precursors. With a focus on polyolefins, recently explored insight into the selectivity of cross metathesis along with its powerful utility in total synthesis will be presented.
