用于实验确定聚合物、蛋白质、多肽、表面活性剂和低分子有机分子在界面的结构和动力学的各种仪器将由学术研究基础设施计划提供资金购买。将获得的仪器包括：1)布儒斯特角度显微镜/光学偏振仪，2)SPEX Fluorolog 212光谱荧光仪，3)TopMetrix TMX-2000扫描探针显微镜，以及4)纳米量热计。该仪器将用于研究由低分子量两亲分子、合成聚合物或厚度从10埃到1000埃的蛋白质组成的有机薄膜。单独的主题包括：朗缪尔和朗缪尔-布洛杰特薄膜的形态和光谱；均匀表面流下的单分子膜；薄固体薄膜的磁区形成、弛豫行为和表面特性，包括自组装单分子膜中的横向结构；以及超薄固体薄膜的热转变。为了研究由低分子化合物、合成聚合物和蛋白质组成的有机薄膜，将获得显微镜/光学偏振仪、荧光分光光度计、扫描探针显微镜和纳米量热计。

Various instrumentation that is collectively directed to the experimental determination of the structure and dynamics of polymers, proteins, polypeptides, surfactants and low molecular weight organic molecules at interfaces will be purchased with funds from the Academic Research Infrastructure Program. The instrumentation to be acquired includes: 1) a Brewster angle microscope/optical polarimeter, 2) a SPEX Fluorolog 212 spectrofluorometer, 3) a TopoMetrix TMX-2000 scanning probe microscope, and 4) a nanocalorimeter. The instrumentation will be used to study organic thin films composed of low-molecular weight amphiphiles, synthetic polymers or proteins with thicknesses ranging from 10 to 1000 Angstroms. The individual topics include: the morphology and spectroscopy of Langmuir and Langmuir-Blodgett films; monolayers subjected to homogeneous surface flow; domain formation, relaxation behavior and surface properties of thin solid films including lateral structure within self-assembled monolayers; and thermal transitions in ultrathin solid films. A microscope/optical polarimeter, spectrofluorometer, a scanning probe microscope and a nanocalorimeter will be acquired to study organic thin films composed of low-molecular weight compounds, synthetic polymers and proteins.
