9727708 Fisch The overall goal of this research is to obtain a better understanding of the physical and chemical properties of several unique self-assembled systems in the dilute, semidilute, and concentrated solution regime. Mixtures of both anionic and cationic surfactants will be studied as a function of temperature, solvent salinity, and relative concentration of the two surfactants. Surfactant-alcohol mixtures will also be studied to understand the effects of structural isomers on the physico-chemical properties. These research goals will be achieved by application of a wide variety of optical and physical chemical techniques such as light scattering, viscosity and surface tension techniques to colloidal and micellar systems. %%% Surfactants and mixtures of surfactants are used extensively in industrial processing, biological and pharmaceutical preparations, and drug delivery systems. Students studying the physics and chemistry of self-organization in these systems, and the manipulation of their properties, will acquire skills and knowledge in an area of considerable technological importance. ***

9727708 Fisch这项研究的总体目标是更好地了解稀释，半硅和浓缩溶液制度中几种独特的自组装系统的物理和化学特性。 阴离子和阳离子表面活性剂的混合物将根据温度，溶剂盐度和两个表面活性剂的相对浓度进行研究。 还将研究表面活性剂 - 酒精混合物，以了解结构异构体对物理化学特性的影响。 这些研究目标将通过应用多种光学和物理化学技术（例如光散射，粘度和表面张力技术）来实现。 表面活性剂和表面活性剂的混合物在工业加工，生物学和药物制剂以及药物输送系统中广泛使用。 研究这些系统中自我组织的物理和化学的学生以及对其性质的操纵，将在技术重要性的领域中获取技能和知识。 ***
