Congratulations to the Chemistry Commuters bike team, who scored 4th for their category in the 2014 BTA Bike Commute Challenge.
This year, our twenty-three participants logged 2707 commuting miles in September – that’s up from 1639 miles and a 13th place finish in 2013, with a team of 14 riders.
The BCC is a friendly competition – workplace against workplace – to see who can bike to work more during the month of September.
Mark your calendars and plan on joining us next year!
The University of Oregon Department of Chemistry and Biochemistry began the fall term with a new department head at the helm. On July 1, 2014, Andrew H. Marcus officially stepped up to the position as Michael Haley stepped down.
Professor Haley, of the department’s Organic/Inorganic division, served two 3-year terms as department head beginning in 2008, overseeing a period in which the number of our undergraduate majors nearly doubled and our graduate student enrollments increased 20%. Highlights of his tenure included the building of the new General Chemistry teaching laboratories and student Resource Center, overseeing two classroom remodels, more than doubling the number of teaching assistantships, and the hiring of six new faculty.
Professor Marcus, a Physical Chemist, was selected last spring by the department faculty and the College of Arts and Sciences to serve as the department’s next head. Prof. Marcus has been at the University of Oregon since 1996. This will be his first time serving as department head, and he is looking forward to working with colleagues to push the quality of the department even further.
Please join us as we welcome Andrew Marcus as our new head, and thank Michael Haley for his six years of service to the department!

Title: Structure, Function, and Inhibition of Bacterial Biofilms: Lessons from Small Molecules and a Big Magnet
Bacterial biofilms are complex multicellular assemblies that exhibit resistance to antibiotics and contribute to the pathogenesis of serious and chronic infectious diseases. As insoluble and non-crystalline materials, biofilms pose a challenge to analysis by conventional methods. We are working to transform vague biofilm descriptors from terms like slime and glue into quantitative parameters of chemical and molecular composition. We recently developed an approach that integrates non-perturbative preparation of the extracellular matrix with electron microscopy, biochemistry and solid-state NMR spectroscopy to define the chemical composition of the intact and insoluble extracellular matrix of a clinically important pathogenic bacterium–uropathogenic E. coli. Our data permitted a sum-of-all-the-parts analysis. In our chemical biology efforts, we have also discovered small-molecule biofilm inhibitors of E. coli biofilms and we are examining their influence on biofilm composition and architecture. I will discuss these results and our emerging discoveries in biofilms formed by Vibrio cholerae.
Refreshments will be served at 2:00pm in 377 Klamath
Seminar will begin at 2:30PM in 331 Klamath.

UO Chemistry and Biochemistry Department Head Andy Marcus has been named a recipient of the University of Oregon’s Fund for Faculty Excellence Awards for AY 2014-15.
The award is designed to further the UO’s strategic commitment to improving its academic quality and reputation by recognizing, supporting, and retaining world-class tenure-related faculty. Professor Marcus is one of thirteen exemplary faculty members that were chosen to receive the award this year.
The recipients of this honor are nominated by their deans and recommended by a committee of former recipients. The award recognizes the recipients’ scholarly impact within their respective fields, their contributions to program and institutional quality at the UO, and their academic leadership.
A reception celebrating all of this year’s Fund for Faculty Excellence recipients will be held on October 30th.

“NOVEL PATH-INTEGRAL BASED DYNAMICS FOR PHOTOCHEMISTRY”
The rational design of organic photovoltaics will require a clear understanding of the mechanism of photo- induced charge and energy transfer. In this talk, we describe a recently developed path-integral based method that employs classical molecular dynamics trajectories to simulate quantum dynamic effects in photochemical reactions [1, 2]. Further, we describe our work towards applying this new method to characterize the mechanism of nonadiabatic electronic state transitions for model systems that mimic exciton dynamics in organic photovoltaics.
