Title:
Solving longstanding questions with new light: FLASH - a step-stone to soft X-ray materials science

Abstract:
In materials science, the frontier of knowledge spans from molecular surface dynamics for heterogeneous catalysis with little explored transition states to functional materials with often surprising properties and phase transitions as well as to chemical dynamics in
solution.
In these systems the interplay between local properties and nanoscale phenomena govern their physics and chemistry - and femtosecond soft
X-ray pulses are ideal probes of their dynamics. The Free-Electron LASer at Hamburg (FLASH) has allowed us to take a
great step into femtosecond time resolved X-ray methods based on innovative instrumentation for femtosecond time resolved soft X-ray
spectroscopy and resonant X-ray scattering methods. In this talk the new physics we can access is explored through our research of femtosecond time resolved photoemission as well as resonant inelastic and elastic X-ray scattering for materials science at FLASH.
