  1. Liquid Interfaces: Summary • Key scientific drivers: • Interfacial processes: biological, chemical, physical. Liquid mixtures, salts, and alloys. • Active interfaces: Liquid-liquid electrolytes, catalytic surfaces, nucleating template films. • Biomimetic films, membranes, activity of proteins biological function and disease. • Experiments enabled by NSLS-II, not presently possible • In-situ scattering with time resolution, elemental contrast, and high structural resolution. • Microfocussing to address more samples and enable more efficient detectors to be used. • High energy instrumentation for work at buried interfaces. • Low energy instrumentation for resonance from light elements. • Technical capabilities required • Stable small beam. Fixed-position energy tunability. Optics for microfocussing. • - high energy line (50 keV) for buried interfaces • - liquid spectrometer line with 2-30 keV range • Detector requirements: Fast area detector, ideally R+D for E discrimination < 5 eV • Software and computing infrastructure: YES. Data server, conferencing, grid access. • Ancillary equipment: New developments in simultaneous microscopy, spectroscopy • Laboratory / hutch ESH: Suitable for all chemistries, nanoparticles.

  2. Liquid Interfaces: Summary Communities which participate and benefit: Liquid interfaces; buried interfaces; catalysis and mineral-liquid communities Two full-, three part-time LSS’s at NSLS and APS, used by 30+ PI’s plus: non-independent collaborators; students/postdocs; international LSS experts; neutron scattering community. Typical to use 10 days/run. High energy station working group: Ocko, Zhong, Schlossman, DiMasi LSS and energy tunable station, low energy spectrometer working group: DiMasi, Fukuto, Blasie, Schlossman, Kuzmenko, Pershan, Lösche, Ocko, et al Proposal: build state of the art 6.5-30 keV NSLS instrument now jump-start the community ahead of time move new instrument to NSLS-II
