"Hydrogenase- and Acetyl coA Synthase-Inspired Bioorganometallic Chemistry"
Professor Marcetta Y. Darensbourg is a native of Kentucky, USA, with a Ph.D. from the University of Illinois. Following academic posts at Vassar College and Tulane University, she joined the faculty at Texas A&M University, College Station, TX, in 1982. She holds the title of Distinguished Professor of Chemistry. 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 enzymes 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. Metalloenzyme active sites that catalyze carbon-carbon coupling reactions but use abundant metals such as nickel also inspire her research activities.
She was an inaugural, 2009, Fellow of the American Chemical Society. Dr. Darensbourg was also elected as a fellow of the American Academy of Arts and Sciences in 2011, to the Royal Society of Chemistry in 2014, and the National Academy of Sciences in 2017. Most recently, she was selected by the Southeastern Conference as the 2018 SEC Professor of the Year.
Sheldon G. Shore Lecture
Sheldon Shore was born in Chicago in 1930. After completing his Bachelor's degree at the University of Illinois in 1951, he moved to the University of Michigan where he completed his Master's (1953) and Doctoral degrees (1957). Shortly thereafter, he moved to join the Chemistry faculty at The Ohio State University, where he provided 57 years of distinguished service.
Professor Shore’s research spanned vast areas of the periodic table, but perhaps he is best known for his pioneering work in the area of boron hydrides, metal cluster carbonyls and lanthanide transition metal systems. He and his coworkers developed the first rational synthesis of B4-B10 boron hydrides and one of his early compounds, ammonia borane, which had been predicted to be too unstable to isolate, was isolated by him and shown to be stable at elevated temperatures. It is currently a hot topic for hydrogen storage and release. He produced the first well-defined examples of boron nitride nanotubes, analogs of multi-walled carbon nanotubes. His mechanistic studies of the synthesis of metal cluster carbonylates and the water-gas shift reaction attracted wide attention. This work has been featured in current treatises on cluster chemistry and is also described in inorganic chemistry text books. His work on mixed metal clusters of lanthanide-transition metal elements and their conversion to nanoparticles has led to new heterogeneous catalysts for the selective hydrogenation of phenol to cyclohexanone, hydrodechlorination of chlorobenzenes, and the reforming of propane.
Dr. Shore authored over 300 scientific publications and 14 patents. He received numerous awards and recognitions for his research. Most notable among them is the Chemical Society’s Columbus Section Award, the Morley Medal of the Cleveland Section, the ACS Award for Inorganic Chemistry and election as a corresponding member of the Bavarian Academy of Sciences. The Ohio State University also recognized him with the Distinguished Lecturer Award, the Distinguished Scholar Award, the Charles H. Kimberly Chair of Chemistry, and the Distinguished Professor of Mathematical and Physical Sciences Award. During Dr. Shore’s tenure at OSU, 91 students completed MS or Ph.D. degrees with him, and many more postdoctoral fellows and visiting scholars were associated with his laboratory, not including the thousands of undergraduates who passed through his classes. Over a long and active career, Sheldon Shore left a profound and indelible imprint on the lives of the many faculty, staff, and students of the broader Ohio State University family that were fortunate to know him. The annual Sheldon G Shore Lecture provides an opportunity to remember and celebrate his achievements.
