Presidential Young Investigator Award: Microemulsions - Fundamentals and Applications

本项目研究微乳液；研究的目的是提高对微乳液中的相变、微结构、块体和界面性质及相互作用的了解。我们将使用一系列分析工具来研究含有非离子型、离子型和两性离子表面活性剂的纯组成体系。可使用的技术包括动态光散射和电化学法测量扩散系数和聚集体尺寸，维里系数和旋转半径的平均强度测量，电荷系统中Zeta电位的电泳光散射，以及界面张力的表面光散射。这些测量将得到必要的相行为和分析研究的补充。将确定成分、温度和压力的影响，并将开发相关关系来模拟行为。

This project investigates microemulsions; the objective of the research is to improve on the understanding of phase transitions, microstructures, bulk, and interfacial properties and interactions in microemulsions. Pure component systems containing non-tonic, ionic, and zwitterionic surfactants will be investigated using a battery of analytic tools. Techniques to be used include dynamic light scattering and electrochemical methods for diffusion coefficients and, hence, aggregate size, average intensity measurements for the virial coefficients and radius of gyration, electrophoretic light scattering for zeta potential in charge systems, and surface light scattering for interfacial tensions. These measurements will be complemented with necessary phase behavior and analytical studies. The effects of composition, temperature, and pressure will be determined, and correlations will be developed to model the behavior.
