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. ***

小行星9727708菲施 本研究的总体目标是更好地了解几种独特的自组装系统在稀，半稀和浓溶液制度的物理和化学性质。 将研究阴离子和阳离子表面活性剂的混合物与温度、溶剂盐度和两种表面活性剂相对浓度的关系。 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应用各种各样的光学和物理化学技术，如光散射，粘度和表面张力技术的胶体和胶束系统来实现。 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。 学生学习这些系统中自组织的物理和化学，以及对其属性的操纵，将获得具有相当重要技术意义的领域的技能和知识。 ***
