Synchrotron X-ray surface scattering is the most powerful probe of the 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 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. 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. It has been used to investigate a wide range of chemical and materials interfacial phenomena, including those relevant to the environment, biomolecular materials, life processes, self-assembly, and directed assembly for tailored functionality.<br/>
