Probing Catalysis in Real Time

Anders Nilsson presents "Probing Catalysis in Real Time" at the next APS Colloquium Thursday, Nov. 19, 3 p.m., Bldg. 402 Aud.


In heterogeneous catalysis, reactants adsorbed on surfaces are converted to products, which eventually desorb via various intermediates. The transition state separates reactants and intermediates from products and the free energy required to reach it determines the kinetics of an elementary chemical reaction.

Global Performance of Covariant Density Functional Theory

Density functional theory is one of few theoretical approaches which allows to describe the nuclei across full nuclear landscape. I will base my talk on the results obtained in covariant density functional theory (CDFT) which is a modern theoretical tool for the description of low-energy nuclear phenomena. In its framework the nucleus is described as a system of nucleons which interact by the exchange of different mesons and this description is based on the Dirac equation. First, I will discuss the basic features of the CDFT.

Charge Transfer at the Nano Scale: Single Molecule and X-ray Photoemission Spectroscopy Measurements

Understanding and controlling electron transfer across metal/organic interfaces is of critical importance to the field of organic electronics and photovoltaics. Single molecule devices offer an ideal test bed for probing charge transfer and mechanics at these interfaces, while x-ray photoemission measurements enable a probing of femtosecond dynamics of charge transfer across interfaces.
