ABSTRACT Proposal Number: CTS-9805896 Principal Investigator: C. Steiner A POWRE Award. The proposal is to study the self-assembling of amphiphilic molecules on surfaces in a variety of configurations: monolayers, bilayers, hemimicelles. The work will concentrate on two equilibrium surface phases, liquid condensed and liquid expanded and will focus on two dimensional assemblies of binary mixtures of surfactants on hydrophobic substrates. Fluorescence microscopy will permit direct visual observation of the domain structure, infrared spectroscopy to provide information about the average thickness and composition of the surface layer, and atomic force microscopy to determine the orientation of the molecules. The information will be used to understand the relationship between the characteristics of the absorbed layer, structure and composition, and the desorption kinetics of self-assembly. This POWRE award will enable the PI to initiate research in a new discipline and to take advantage of related state-of-the art technology.

摘要 提案编号：CTS-9805896 主要研究者：C.施泰纳 一个权力奖。 该计划旨在研究两亲分子在表面上以各种构型的自组装：单层，双层，半胶束。 这项工作将集中在两个平衡的表面相，液体冷凝和液体膨胀，并将集中在二维组件的二元混合物的表面活性剂的疏水基板上。 荧光显微镜将允许域结构的直接视觉观察，红外光谱提供关于表面层的平均厚度和组成的信息，以及原子力显微镜确定分子的取向。 这些信息将被用来了解吸附层的特性、结构和组成以及自组装的脱附动力学之间的关系。 该POWRE奖将使PI能够在新学科中开展研究，并利用相关的最先进技术。
