THE MORK FAMILY DEPARTMENT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCEPRESENTS A SEMINAR
BYKen Nealson
Wrigley Professor of Environmental Sciences Department of Earth Sciences and Biological Sciences University of Southern CaliforniaonExtracellular Electron Transport: Mechanism(s) and Applicationsabstract Microbes constitute more than half the biomass on our planet  their immense success is, in large part, due to their ability to catalyze reactions at rates orders of magnitude higher than they would occur in the absence of life, using protein catalysts called enzymes. In particular, microbes are experts at electron transfer, seemingly being able to transfer an electron to any substrate that will accept one. Recently, it was discovered that microbes have the capacity to donate electrons to solid substrates (e.g., solid metal oxides or metal-rich clays), leading to rapid catalysis of these substrates via direct electron transport. One such organism, Shewanella oneidensis is seemingly the master of this type of metabolism, being capable of reduction of more than 15 different substrates, including iron and manganese oxides, metal rich clays, and even the anodes of fuel cells. The nature of the electron transfer process, while still being elucidated, shows hints of being something different from anything
previously observed. Under conditions of electron acceptor limitation, S.
oneidensis makes copious amounts of extracellular enzymes, as well as long extracellular structures (nanowires) that are highly conductive, and necessary for the reduction of solid metal oxides, and the production of current in microbial fuel cells. Results of recent studies of the nanowires and their properties will be discussed.Location: John Stauffer Science Lecture Hall (SLH) - 102

Handy Colloquium INFLUENCE OF MATERIALS TECHNOLOGY ON THE FUEL EFFICIENCY OF AEROTURBINES Professor Anthony G. EvansDepartment of Materials & Mechanical Engineering
University of California
Santa Barbara, CAAbstractThe fuel efficiency of aero-turbines has been improved systematically during recent decades. The trend is strongly correlated with the increase in achievable temperature in the hot sections of the turbine. In turn, this temperature increase is attributed to combined advances in materials and active cooling technologies. This presentation examines the materials innovations that continue to be implemented due to advancements at the frontiers of materials and mechanics. The most recent advances have been enabled by multilayer coatings that impart thermal and oxidation protection. The former is provided by an oxide with exceptionally low thermal conductivity. The latter is achieved using alloy coatings that form alumina. For continued performance enhancement using such multilayer concepts a systems-level methodology is needed. The materials and mechanics formulations that have been devised for this purpose are described.
