Updated 5/8/07 (Fuoss replaces Falcone)


Advances in detector technology and radiation sources are opening unprecedented scientific opportunities to probe chemical/physical processes with atomic-scale resolution and on the time-scale of the process itself. Time resolution on the order of minutes to seconds affords probing chemical transformations such as phase transitions, host/guest reactivity, nucleation and crystal growth. Ultrafast X-ray science using picosecond to femtosecond pulses along with ultrafast laser technology, is uncovering previously unresolved phenomena in atomic, molecular and optical physics, biology, chemistry, condensed matter and material science.

This workshop will highlight emerging science and articulate grand challenges associated with time resolved scattering. In a two part symposium world leaders across disciplines will discuss the application of time resolved scattering to (1) deciphering atomic level mechanistic details of chemical transformations and (2) measuring ultrafast atomic and molecular dynamics.
