The PI's recently discovered spontaneous, monodisperse, equilibrium vesicles in many mixtures of anionic and cationic surfactants. In this program, they will characterize experimentally and model theoretically the process of vesicle formation in these systems. This work will uncover a rich new area of surfactant phase behavior and suggest new formations for stable vesicles useful in addressing theoretical and practical problems. They will use a combination of experimental techniques including light, x-ray and neutron scattering, fluorescent probes, rheological measurements, and electron microscopy. Simultaneously they will approach the problem from two distinct and complementary theoretical directions. This work is significant because the properties of vesicles in these mixtures and the nature of the micelle- vesicle and vesicle-liquid crystal transitions is of keen scientific interest and considerable practical importance. This project has a broad scope and in order to achieve these goals expeditiously they will collaborate with several industrial and academic researchers.

PI 最近在许多阴离子和阳离子表面活性剂的混合物中发现了自发的、单分散的平衡囊泡。 在这个项目中，他们将对这些系统中囊泡形成的过程进行实验表征和理论建模。 这项工作将揭示表面活性剂相行为的丰富新领域，并提出可用于解决理论和实际问题的稳定囊泡的新形成。 他们将结合使用光、X 射线和中子散射、荧光探针、流变测量和电子显微镜等实验技术。 同时，他们将从两个不同且互补的理论方向来解决这个问题。 这项工作意义重大，因为这些混合物中囊泡的性质以及胶束-囊泡和囊泡-液晶转变的性质具有强烈的科学兴趣和相当大的实际重要性。 该项目范围广泛，为了迅速实现这些目标，他们将与几位工业和学术研究人员合作。
