X-ray Scattering Studies of Interfaces Between Two Immiscible Electrolyte Solutions

在分析和表面化学计划的支持下，伊利诺斯州-芝加哥大学的Schlossman教授和北方伊利诺斯州大学的Vanysek教授及其同事正在解决带电液-液界面结构的长期问题。 使用组合的小角度X射线散射，X射线反射率，和电化学探针，不混溶的液体之间的整洁的界面的结构，和界面改性的表面活性剂分子，正在检查。 这一基础性工作的结果将影响我们对膜转运过程、分离过程和药物递送设计的理解。 从事该项目的学生将接触到研究和教育中广泛的跨学科问题。 液-液界面的结构是电化学和物理化学中一个长期存在的问题。 Schlossman和Vanysek教授正在进行详细的电化学和X射线散射测量，为这些结构问题提供答案。 这项工作的基础知识将影响我们对生物膜，传感器设计和药物输送系统的理解。

AbstractCHE-0615929Schlossman/Illinois-ChicagoWith the support of the Analytical and Surface Chemistry Program, Professor Schlossman at the University of Illinois-Chicago, and Professor Vanysek at Northern Illinois University and their coworkers, are addressing long standing questions of the structure of electrified liquid-liquid interfaces. Using a combination of small angle X-ray scattering, X-ray reflectivity, and electrochemical probes, the structure of the neat interface between immiscible liquids, and that interface modified by surfactant molecules, is being examined. The results of this fundamental work will impact our understanding of membrane transport processes, separations processes, and drug delivery design. Students working on this project are exposed to a broad range of interdisciplinary issues in research and education. The structure of the liquid-liquid interface is a long standing question in electrochemistry and physical chemistry. Professors Schlossman and Vanysek are carrying out detailed electrochemical and X-ray scattering measurements that are providing answers to these structural questions. Fundamental knowledge from this work will impact our understanding of biological membranes, sensor designs, and drug delivery systems.
