Seminar

Artificial Photosynthesis with Particles


Prof. Frank Osterloh , Professor of Chemistry , University of California, Davis
Artificial Photosynthesis with Particles
The identification of an artificial photosynthesis method to turn solar energy into globally usable amounts of fuel is considered one of the most important challenges today. Photochemical water splitting with particle-based systems has the greatest potential to achieve this goal. Currently, the development of such systems is limited by intrinsic materials issues and by an incomplete understanding of photochemical charge separation on the nanoscale. This talk will discuss these obstacles and present ways to overcome them using recent examples from the literature and from the author’s own laboratory.

Seminar

Mechanistic and Electronic Structural Insights into the Metallobiochemistry of Nitrification


Prof. Kyle Lancaster , Assistant Professor, Cornell University
Mechanistic and Electronic Structural Insights into the Metallobiochemistry of Nitrification
Nitrification, the oxidation of ammonia to nitrite and nitrate, is a key entry point for fixed nitrogen to return to the atmosphere as dinitrogen. Nitrification is the root of tremendous economic loss in agriculture as well as a major ecological hazard via nitrogenous eutrophication. Molecular details concerning the elementary, multi-electron chemical steps whereby ammonia is oxidized to hydroxylamine and ultimately to nitrite remain elusive. This may be attributable in part to the difficulty associated with accessing sufficient quantities of relevant enzymes for biophysical characterization. Nevertheless, such insights are attractive because they hold the promise of inspiring novel, green chemical methods for difficult bond activations and multi-electron transformations. This talk will describe our investigation of the crucial molecular steps of nitrification revealed through the application of rapid kinetics, spectroscopy, and electronic structure calculations. Key insights include the establishment of a direct link between nitrification and nitrous oxide pollution, the identification of important intermediates in hydroxylamine oxidation by both Fe, and a revision of the enzymatic steps involved in hydroxylamine oxidation. The seminar will conclude with reinterpretation of the electronic structure of high-valent copper–oxygen species toward rationalizing competence of these species for challenging E–H bond activations.
