"Crossing Interfacial Frontiers: Surface Chemical Dynamics at the Temporal and Spatial Limit." Surface chemical reactions have been used successfully to remove environmental pollutants, fabricate microelectronics, and produce vital chemicals such as fertilizer, fuel and food. But understanding the chemical dynamics of these reactions is limited, and the ability to study real-time surface chemistry is just being developed. Camillone discusses recent results of studies of the oxidation of carbon monoxide on the surface of palladium, which have resulted in new insights into molecule-molecule and molecule-surface interactions.

| Speaker: | Nicholas Camillone III, Ph.D., Chemistry Department | | Host: | Brant Johnson and Fulvia Pilat | | Date: | Wednesday, April 16, 2008 | | Time: | 4:00 PM | | Abstract: | Surface chemical reactions are ubiquitous in nature and industry: they have been used successfully to remove environmental pollutants, fabricate microelectronics, and produce vital chemicals such as fertilizer, fuel and food. But understanding the chemical dynamics of these reactions is limited, and the ability to study real-time surface chemistry is just being developed.
The lecturer will discuss recent results of studies of the oxidation of carbon monoxide on the surface of palladium, which have resulted in new insights into molecule-molecule and molecule-surface interactions.
In addition, he will describe a new project at the Center for Functional Nanomaterials that combines ultra-fast laser excitation with a new, state-of-the-art scanning tunneling microscope to probe electronic excitation and photo-induced chemistry at surfaces. It will have a resolution in both space and time that will allow the speaker and his colleagues to watch fast chemical processes at a molecule's eye-view. |
