There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Electron- and photon-induced chemistry on surfaces: A meandering path through our solar system
It is well known that electronic excitation of surfaces and interfaces leads to chemical modification and transformation. These âtransformationsâ can be brought about by photon-, electron- or ion-impact and can occur in radiation environments within the interstellar media, near star forming regions, within plasmas or in radioactive containment facilities. Since the chemical modification processes are inherently non-equilibrium, the chemical products are often rather exotic and not easily produced under normal thermal conditions. This talk will emphasize some of our groupâs recent experimental and theoretical developments in the study of low-energy (5-100 eV) electron- and (vacuum) ultraviolet photon-interactions with complicated surfaces and interfaces. A specific attempt will be made to demonstrate the importance of this work in planetary science, materials science, and biophysics.
