The role of solvation in interfacial electrochemistry is the focus of this research project, supported by the Analytical and Surface Chemistry Program. Ion transfer reactions, probed spectroscopically and electrochemically, will be used to study the mechanism of solvation. Single crystal gold electrodes modified with self-assembled monolayers form the basis of the work. The role of water at these interfaces will be probed using admittance measurements and simple electron transfer test reactions. Solvation in very fast electron transfer processes will be examined, and the theory of solvation for these systems will be developed. The information generated by this study will be useful in developing an understanding of charge transfer and control in biological membrane systems. An experimental and theoretical study of charge transfer at organic monolayer modified gold electrodes is the focus of this research project. Understanding the mechanism and kinetics of electron transport across these model membranes will be useful for understanding the role of solvation in these biological model systems.

在分析和表面化学计划的支持下，溶剂化在界面电化学中的作用是该研究项目的重点。 从光谱和电化学上探测的离子转移反应将用于研究溶剂化的机理。 用自组装单层修饰的单晶金电极构成了工作的基础。 水在这些界面中的作用将使用入学测量和简单的电子转移测试反应进行探测。 将检查非常快速的电子传输过程中的溶剂化，并将开发这些系统的溶剂化理论。 这项研究产生的信息将有助于发展对生物膜系统中电荷转移和控制的理解。 该研究项目的重点是有机单层修改金电极上电荷转移的实验和理论研究。 了解跨这些模型膜的电子传输的机制和动力学将有助于理解溶剂化在这些生物模型系统中的作用。
