1125791CastnerThis proposal requests funding to design, build and commission a femtosecond SFG scattering instrument. Once commissioned it will be used to examine the structure of molecules at interfaces (liquid/solid, air/solid, air/liquid). The scattering patterns generated by this instrument from particles in solution provide insight into the size and shape of the particles. The spectra generated by this instrument provide information about the structure of molecules bound to these particles. A femtosecond SFG scattering instrument is ideal for in situ characterization of nanoparticles (NPs) in complex solutions and will provide important, new information about those NPs, molecules bound to the NPs, and solvent molecules interacting with the NPs. This instrument will be integrated into the National ESCA and Surface Analysis Center for Biomedical Problems (NESA/BIO), allowing a wide range of researchers access to this novel instrument.

1125791 Castnerthis提案要求资金设计，构建和委托飞秒SFG散射工具。一旦委托，它将用于检查界面（液体/固体，空气/固体，空气/液体）的分子结构。该仪器从溶液中产生的仪器产生的散射模式提供了对颗粒大小和形状的洞察力。该仪器生成的光谱提供了有关与这些颗粒结合的分子结构的信息。飞秒SFG散射仪器是复杂溶液中纳米颗粒（NP）的原位表征的理想选择，并将提供有关这些NP，与NPS结合的分子以及与NP相互作用的溶剂分子的重要新信息。该仪器将集成到国家ESCA和地表生物医学问题中心（NESA/BIO）中，从而使许多研究人员可以使用这种新颖的仪器。
