POWRE: Self-Assembly of Mixtures of Surfactants at the Hydrophobic Solid/Air Interface

项目编号：CTS-9805896项目负责人：C. Steiner A power Award。建议是研究两亲分子在各种结构表面上的自组装：单层，双层，半束。这项工作将集中在两种平衡表面相，液体凝聚和液体膨胀，并将重点放在表面活性剂二元混合物在疏水基质上的二维组装上。荧光显微镜可以直接观察畴结构，红外光谱可以提供关于表面层的平均厚度和组成的信息，原子力显微镜可以确定分子的方向。这些信息将用于理解吸收层的特征、结构和组成以及自组装的脱附动力学之间的关系。该power奖将使PI能够启动新学科的研究，并利用相关的最新技术。

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.
