Structure and Dynamics of Micelles and Microemulsions

Linda J.Magid博士得到了实验物理化学计划的资助，通过各种实验技术研究表面活性剂在水和碳氢化合物中的聚集。这类研究可能会设计出一种全新的洗涤剂家族，此外，还可能让我们更多地了解洗涤剂的结构。研究的主要目的是：(1)在给定胶束形成和破裂的动力学条件下，评估拉长胶束结构在溶液中表现为聚合物的程度；(2)界面膜波动对表面活性剂(和聚集体)结构的依赖；(3)能够区分液滴和所谓的生物连续聚集形态的技术的发展。

Dr. Linda J. Magid is supported by a grant from the Experimental Physical Chemistry Program to study the aggregation of surface active agents in water and hydrocarbons by a variety of experimental techniques. These kinds of studies may allow for the design of an entirely new family of detergents and, in addition, may allow us to learn more about the structure of cleansing agents. The main goals of the investigation are: (1) an assessment of the extent to which elongated micellar structures in solution behave as polymers, given the dynamics of micelle formation and breakdown; (2) the dependence of the interfacial film fluctuations on surfactant (and aggregate) structure; (3) the development of techniques which enable differentiation between droplet and so-called biocontinuous morphologies of aggregation.
