Professor Marcetta Y. Darensbourg from Texas A&M University will be giving her award winning lecture titled \'<u>Old Biology Inspires New Chemistry: </u>The Hydrogen Economy from Pond Silt to Photovoltaic/Fuel Cells.\' Trained as an organometallic chemist and with earlier research programs in low valent transition metal hydrides\, the possibility of metal hydrides in nature\, specifically as intermediates in hydrogenase metalloenzymes lured her into the new field of bioorganometallic chemistry. She has been a leader in the development of synthetic analogues of the diiron hydrogenase active site and the insight they bring to the catalytic mechanism of these natural fuel cell catalysts. Refreshments will be served before the event starting at 6:30pm.
