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.

溶剂化在界面电化学中的作用是本研究项目的重点，由分析和表面化学计划支持。 离子转移反应，探测光谱和电化学，将被用来研究溶剂化的机制。 自组装单分子膜修饰的单晶金电极构成了这项工作的基础。 水在这些界面的作用将使用导纳测量和简单的电子转移测试反应进行探测。 溶剂化在非常快的电子转移过程中将被检查，这些系统的溶剂化理论将被开发。 这项研究所产生的信息将有助于发展的理解在生物膜系统中的电荷转移和控制。 本研究的重点是对有机单层膜修饰金电极上电荷转移的实验和理论研究。 了解这些模型膜的电子传递的机制和动力学将有助于了解溶剂化在这些生物模型系统中的作用。
