Cross-Divisional Chemistry Seminar: Prof. R. David Britt

Inorganic Seminars "mm-Wave (263 GHz) high power pulse EPR spectrometer and applications to high spin transition metal centers" Professor R. David Britt - Department of Chemistry, University of California, Davis Hosts: Julie Kovacs, Lauren Rajakovich, Stefan StollPulse Electron Paramagnetic Resonance (EPR) spectroscopy provides powerful tools for examining species with unpaired electrons, such as organic radicals and metal ions, in a wide variety of interesting systems. However, the lack of high power pulse amplifiers above approximately 100 GHz has limited its applicability at very high frequencies and magnetic fields. Here we describe the use of a new high frequency traveling wave (TWT) vacuum tube amplifier employed in a pulse EPR spectrometer operating over a wide frequency bandwidth centered at 263 GHz. The TWT power allows for pulse EPR without any resonator, which gives big advantages for sample volume and sample geometry. This novel instrument provides significant improvements in sensitivity and resolution when compared… Event interval: Single day event. Campus location: Bagley Hall (BAG). Campus room: BAG 261.

Physical Chemistry Seminar: Prof. Zhi Heng Loh

Physical Seminars "Spatially Resolved Ultrafast Dynamics of Two-Dimensional Materials Probed by Time-Resolved Photoemission Electron Microscopy" Associate Professor Zhi Heng Loh - School of Chemistry, Chemical Engineering and Biotechnology, Nanyang Technological University, Singapore Host: Munira Khalil The application of two-dimensional transition metal dichalcogenides (TMDs) to optoelectronics requires a detailed understanding of their elementary carrier dynamics. In this talk, I will present some results obtained from our investigations of TMDs using femtosecond time-resolved photoemission electron microscopy (TR-PEEM). In 1L-WSe2, TR-PEEM imaging uncovers spatially heterogeneous dynamics within a single flake. Notably, the edges exhibit faster intervalley electron scattering and slower exciton–exciton annihilation compared to the interior. In wrinkled multilayer MoS2, TR-PEEM and nonadiabatic ab initio molecular dynamics simulations reveal faster sub-picosecond electronic relaxation in wrinkled regions, driven by enhance… Event interval: Single day event.

Weston T. and Sheila Borden Endowed Lecture in Theoretical Chemistry: Prof. Benedetta Mennucci

Physical Seminars Weston T. and Sheila Borden Endowed Lecture in Theoretical Chemistry "Photoactivated biological functions: Bridging Electronic Excitations to Functional Response through Multiscale Simulations" Professor Benedetta Mennucci - Department of Chemistry, University of Pisa Host: Xiaosong Li Living organisms across all domains of life rely on specialized light-sensitive proteins to detect and respond to light. Although these systems adopt diverse molecular strategies, they share a common triggering event: the electronic excitation of a chromophoric unit embedded within the protein. This initial excitation is subsequently converted into different forms of energy and propagated through the system, ultimately leading to a biological response. The underlying processes span multiple spatial and temporal scales, ranging from ultrafast electronic dynamics localized on the chromophoric unit to much slower, large-scale conformational changes of the protein matrix. Here, a multiscale computational framework is presented t… Event interval: Single day event. Campus location: Electrical and Computer Engineering Building (ECE). Campus room: ECE 125. Accessibility Contact: chem59x@uw.edu. Event Types: Lectures/Seminars. Event sponsors: This lecture is supported by the Weston and Sheila Borden Endowed Fund in Chemistry, established by the Bordens in 2015. Weston T. Borden served on the University of Washington chemistry faculty for 31 years. His research involved the use of molecular orbital (MO) theory and MO-based calculations to understand and predict the structures and reactions of organic and organometallic molecules.

Organic Chemistry Seminar: Prof. Bo Li

Organic Seminars "New Chemistry from Microbial Genomes" Professor Bo Li - Department of Chemistry, University of North Carolina at Chapel Hill Host: Lauren Rajakovich Drugs with origins in microbial small molecules increased both average human life span and quality of life. Microbial genomes harbor many gene clusters dedicated to the biosynthesis of bioactive small molecules; most of these clusters remain uncharacterized. My research group discovers new chemistry from bacterial genomes. We study cryptic biosynthetic gene clusters and identify bioactive small molecules. For example, we identified several antimicrobial and cytotoxic small molecules produced by the opportunistic human pathogen Pseudomonas aeruginosa. Defining the biosynthetic pathway of these molecules yielded new enzymes for biocatalysis and synthetic biology. Our work also revealed previously unknown bacterial molecules that affect the health of human hosts. Event interval: Single day event. Campus location: Chemistry Building (CHB). Campus room: CHB 102.
