Structural Analyses of Complex Fluids: Inverse Scattering and Size and Charge Dispersity

点击翻译按钮获取中文摘要

The proposal seeks to develop a novel method for the analysis of radiation scattering data from a broad class of materials, ranging from atomic to supramolecular. The method seeks to obtain the details of the effective interatomic or interparticle forces to an extent which has not been possible previously, and is useful at conditions at which such forces dominate interfacial phenomena and macroscopic behavior and properties of the materials. The focus of the work is in the study of colloidal materials and micellar and microemulsion systems. However, the potential impact of the work is broader and can be applied to the study of simple liquids and liquid metals as well as structurally arrested materials such as gels and glasses. This work will be coordinated with x-ray, neutron, and light scattering studies currently in progress.
