Below is a collection of a few research presentations I’ve given. A brief description is given for each, along with who the intended audience was. Additional presentations are available on request.
Atomic Harmonies: Surface dynamics, x-ray speckles, catalysis and what it all means for you.
An hour long presentation based on a talk given at Rochester Institute of Technology. The talk is intended for an undergraduate audience. Background surface science relevant to our study of Au and Pt surfaces as well as the basic ideas behind “speckle,” diffraction, and modern light sources. Results from the step-flow motion experiment from Pt (001) are shown, followed by brief discussion of Au (001) in vacuum and in electrolyte experiments.
Coherent Surface Scattering: Au (001) and Pt (001) and their high temperature surface phase transitions.
A thirty minute invited talk given at Northwestern University during the 11th Surface X-ray and Neutron Scattering conference. Surface scattering community was the intended audience. Discusses the basics of coherent x-ray surface scattering and presents results for Au (001) (mature by this point) and Pt (001) (which were preliminary), both in vacuum.
Questioning Nobility -or- CO and Au (001) Surface Reconstruction Pressure and Temperature Effects.
A thirty minute talk delivered at UIUC during an annual Physical Electronics Conference. The target audience was graduate students in surface science. Experiment and results for the interaction of CO gas with the Au (001) surface are shown. The pressure-temperature phase diagram is given, along with observed reaction kinetics, the resulting fits, and activation energies associated with them.
The Persistence of Memory : What Can Soft X-rays Tell Us About The Influence of Disorder on Magnetic Memory?
This is an hour long talk given at Oak Ridge National Laboratory intended for a general condensed matter physics and materials science audience. Experiments, discussion, analysis and modeling of the “pressure series” of cobalt:platinum magnetic thin film samples are shown.
