National Synchrotron Light Source II

NSLS-II is a state-of-the-art 3 GeV electron storage ring. The facility offers scientific and industrial researchers an array of beamlines with x-ray, ultraviolet, and infrared light to enable discoveries in clean and affordable energy, high-temperature superconductivity, molecular electronics, and more. Overview »


The next deadline for NSLS-II beam time proposals and beam time requests is September 30, 2018.  |   Submission Details

Beamlines at the National Synchrotron Light Source II are open to academic and industrial users for scientific research. All research proposals are subjected to peer review and ranked against competing proposals based on scientific merit.

Beamline Projects

When fully built out, National Synchrotron Light Source II will accommodate approximately 60 to 70 beamlines. Thirty beamlines are currently in various stages of development and will provide significant research capacity in early operations.

    Nanoemlusions are finding numerous applications in the fields of pharmaceuticals, food production, materials synthesis and cosmetics. With the search for broader and improved usage of these unique droplets comes the need to better understand the molecular interactions at the surface that lead to their stabilization. This presentation will focus on our most recent efforts in measuring the molecular structure of the oil-water interface and the unique environment it provides for adsorption of molecules, surfactants and macromolecules at both planar and nanoemulsion oil/water interfaces. The studies are a combination of spectroscopic and thermodynamic measurements coupled with theoretical simulations.
