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.

The scientific scope of the liquid surface and interface research at NSF’s ChemMatCARS is summarized as the follows:
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.
