Gregory Botsaris Lecture in Chemical and Biological Engineering
The Department of Chemical &
Biological Engineering is pleased to announce the Gregory Botsaris Lecture in
Chemical and Biological Engineering, to be held on Wednesday April 12, 2017. The
lecture will be given by Dr. Bruce C. Gates, Distinguished Professor of
Chemical Engineering at the
University of California, Davis.
The lecture, entitled "Molecular Metal Complex and Metal
Cluster Catalysts on Supports: Organometallic Chemistry Meets Surface Science,"
will take place at 12:00pm at Alumnae Hall, 40 Talbot Street, Medford.
Parking is available in the Dowling Hall Parking Garage.
This event is open to the public and will be followed by a reception at

Industrial catalysts range from the simple—molecules in
solution—to the complex—the heterogeneous surfaces of robust solids. The
underlying sciences, organometallic chemistry and surface chemistry, are now
merging as researchers succeed in synthesizing and characterizing molecular
species on surfaces. The best understood of these supported catalysts are highly
uniform, being isolated on regular (crystalline) supports such as zeolites.
Spectra, atomic-resolution electron microscopy images, and calculations at the
level of density functional theory characterize the supported species and
demonstrate their high degrees of uniformity. Hence, it is becoming evident how
to design these site-isolated catalysts—the design variables are the metal, the
number of metal atoms in a catalytic site, the support, and other ligands bonded
to the metal. We illustrate some supported molecular catalysts with appealing
properties, such as stability at high temperatures and high selectivity for
challenging reactions such as hydrogenation of 1, 3-butadiene to give butenes.
Bruce C. Gates is a Distinguished Professor at the
University of California, Davis. He teaches in the Department of Chemical
Engineering and formerly he taught at the University of Delaware and worked at
Chevron. His research group is active in catalysis, with a focus on supported
metal complex and metal cluster catalysts that are essentially molecular and
lend themselves to design and in-depth characterization by spectroscopy and
atomic-resolution microscopy. His group also works on catalysis of biomass
conversion, with a focus on hydroprocessing. Gates wrote the textbook
Catalytic Chemistry and coauthored the textbook Chemistry of Catalytic
Processes. Until recently, he edited Advances in Catalysis. He serves
on the U.S. Department of Energy's Basic Energy Sciences Advisory Committee and
the North American Catalysis Society's Board of Directors. His work has been
recognized by numerous awards, including the Alpha Chi Sigma, William H. Walker,
and R. H. Wilhelm awards of the American Institute of Chemical Engineers, the
Award in Petroleum Chemistry and the Gabor Somorjai Award of the American
Chemical Society, and awards from the Council for Chemical Research, and the
North American Catalysis Society. He is a member of the National Academy of
