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.

该项目研究微乳液；该研究的目的是增进对微乳液中相变、微观结构、体积和界面特性以及相互作用的理解。 将使用一系列分析工具研究含有非强效、离子和两性离子表面活性剂的纯组分系统。 使用的技术包括动态光散射和电化学方法，用于测量扩散系数，从而测量聚集体尺寸、维里系数和回转半径的平均强度测量、用于电荷系统中 zeta 电位的电泳光散射以及用于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，并开发相关性来模拟行为。
