Synchrotron x-ray surface scattering is the most powerful probe of molecular and mesoscale structure at liquid-vapor and liquid-liquid interfaces. The precise and flexible design of the liquid surface and interface reflectometer at NSF’s ChemMatCARS (APS, 15-ID-C) and the high brilliance and wide x-ray energy range (5-70 keV) offered in this third generation insertion device beamline provides a world-leading capability for the study of liquid surfaces and buried liquid-liquid interfaces.
Chemistry of life processes and biomolecular materials Including studies of peripheral membrane protein-lipid interactions, anti-microbial peptides, and functional peptide amphiphiles or hybrid bio-nanomaterials
Directed assembly for tailored functionality at liquid interfaces Including studies of organic/inorganic nucleation and mineralization, elastic properties of nanoscopic films, and tunable polymer brushes with mesoscopic patterning
A full suite of x-ray surface scattering techniques is provided to measure atomic, molecular, and mesoscopic ordering at liquid interfaces, including resonant and non-resonant reflectivity, grazing-incidence diffraction and small angle scattering, surface fluorescence, surface diffuse scattering, and fast techniques, such as grazing incidence diffraction in the 1D pinhole geometry.
