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、半稀和浓溶液体系中几种独特自组装系统的物理和化学性质。 将研究阴离子和阳离子表面活性剂的混合物作为温度、溶剂盐度和两种表面活性剂相对浓度的函数。 还将研究表面活性剂-醇混合物，以了解结构异构体对物理化学性质的影响。 这些研究目标将通过在胶体和胶束系统中应用各种光学和物理化学技术来实现，例如光散射、粘度和表面张力技术。 %%% 表面活性剂和表面活性剂混合物广泛用于工业加工、生物和药物制剂以及药物输送系统。 研究这些系统中自组织的物理和化学以及对其属性的操纵的学生将获得具有相当技术重要性的领域的技能和知识。 ***
