The atomic dynamics of metal and alloy droplets of SCALMS systems will be studied in Project A02. Using coherent and incoherent quasielastic neutron scattering (QENS), time (pico- to nanoseconds) and length (nanome-ters) scales relevant for single atom catalysis at the gas/liquid interface will be addressed. The applied methodology allows for decoupling the observation of the atomic dynamics from the slower convection processes and the solid support material hardly contributes to the QENS signal. The QENS data are perfectly suited for validation of atomistic simulations in this CRC. Adapted scattering techniques (XRR, XRD, and (GI)SAXS/SANS) will contribute to structure determination for the whole CRC.
