Wednesday Nite at the Lab
press release: WN@TL goes hybrid both with zoom and with in-person presentations beginning on September 8 at 7pm CT with a special event at the Discovery Building featuring Uwe Bergmann of Physics. The Discovery Building is at 330 N. Orchard Street, Madison. We move back to our longtime home, Room 1111 Genetics Biotech Center, 425 Henry Mall, starting September 15, with a celebration of the 10th Anniversary of the IceCube Neutrino Observatory.
The zoom registration link is still go.wisc.edu/240r59. Starting September 15, you can also watch a live web stream at biotech.wisc.edu/webcams
"Making Movies of Molecules - The Emerging Science of Powerful X-ray Lasers. ”
Description: On November 8, 1895, Wilhelm Conrad Rӧntgen discovered a new invisible form of rays. He called them ‘X-Strahlen’ or X-rays. Since that day, X-rays have revolutionized medical imaging and science. Starting in the 1970s, powerful accelerator rings — the so-called synchrotrons — have dramatically advanced the scientific use of X-rays, by producing intense and highly-focused X-ray beams. Another quantum leap occurred in the late 2000s, when X-ray free-electron lasers came to light. These X-ray lasers produce ultra-short pulses with a brightness over one billion times larger than even the most powerful synchrotron sources. For the first time, scientists can study matter not just at the length scale of atoms and molecules, but also at the femtosecond (10-15 s) timescale of molecular motion. The dream of making molecular movies of a chemical reaction or a biological function in real time is becoming reality. We will describe these machines and present some of the most exciting examples of recent X-ray laser research.
Bio: Uwe Bergmann is the Martin L. Perl Professor in Ultrafast X-ray Science in the Physics Department at the University of Wisconsin-Madison. He got his PhD in Physics from Stony Brook University and did his graduate research at the National Synchrotron Light Source. He has since worked at the European Synchrotron Radiation Facility, the Lawrence Berkeley National Laboratory, the Stanford Synchrotron Radiation Lightsource, the Linac Coherent Light Source, and the Stanford PULSE Institute at SLAC National Accelerator Laboratory.
His research activities focus on the development and application of novel synchrotron and X-ray laser techniques. His scientific interests include studies of the structure of water and aqueous solution, active centers in metalloproteins in particular the photosynthetic splitting of water, hydrocarbons and fossil fuels, functional 2D materials, and imaging of ancient documents and fossils.
