Neutron scattering is an ideal probe of the atomic structure and dynamics in solids, from fast ionic diffusion in solid-state electrolytes to lattice dynamics and thermal transport in thermoelectrics, or structural distortions in metal-halide perovskites. Many of these phenomena bridge the time-scales probed by quasielastic and inelastic neutron scattering (QENS/INS). This presentation will...

Scattering studies are among the few methods that can be used to analyze the structure and dynamics of phospholipid membranes at nanometer scales. However, the available structural information is indirect, as it consists of correlation functions: space-correlation functions for elastic scattering (e.g. SAXS or SANS), and space-time correlation functions for inelastic scattering (e.g. NSE).
