Hamburg Photon Science Colloquium | Unravelling ultrafast surface dynamics on nanoparticles

SemR I-III (CFEL, Bldg. 99)

Understanding surface charge and energy transfer dynamics on nanoparticles is crucial for advancing catalysis. We developed time-resolved reaction nanoscopy with femtosecond temporal and nanometer spatial resolution, to visualize surface charge redistribution and its correlation with bond softening. Complementary multiscale quantum simulations based on non-adiabatic quantum molecular dynamics revealed ultrafast charge transfer processes. Multimodal experiments at EuXFEL and SwissFEL combined momentum-resolved charged particle emission with coherent diffraction imaging. Our findings, enabled by free-electron lasers, highlight future opportunities for exploring nanoscale charge and energy dynamics with ultrashort, bright pulses.

Coffee, tea and cake will be served at 1:45 pm.
