AbstractCHE-0303098Borguet/PittsburghWith the support of the Analytical and Surface Chemistry Program, Professor Borguet and coworkers at the University of Pittsburgh are examining diffusion and self-assembly of macromolecular species at electrochemical interfaces. Using a transient perturbation method, the rate of diffusion as well as information about the control of structures at the electrochemical interface is obtained. Scanning probe microscopy, coupled with this transient perturbation method provides detailed information about the diffusional motion of large molecules on the electrode surface. Initial work is focusing on the motion and self-assembly of porphyrin molecules. An understanding of the diffusion and aggregation of adsorbed species on electrode surfaces may provide a route to the controlled construction of nano-scale objects with interesting technological applications. The work of this project in Professor Borguet's laboratory at the University of Pittsburgh is focused on developing this understanding using transient electrochemical perturbations of the electrode surface followed by scanning probe microscopy characterization.

摘要Che-0303098Borguet/匹兹堡，匹兹堡大学的分析和表面化学计划，Borguet教授和同事正在研究电化学界面上的大分子分子物种的扩散和自组装。 使用瞬态扰动方法，可以获得扩散速率以及有关电化学接口处结构的控制的信息。 扫描探针显微镜，再加上这种瞬态扰动方法，提供了有关大分子在电极表面上扩散运动的详细信息。 最初的工作着重于卟啉分子的运动和自组装。对电极表面上吸附物种的扩散和聚集的理解可能为具有有趣的技术应用的纳米尺度对象的受控构造提供了途径。 该项目在匹兹堡大学的Borguet教授实验室中的工作着重于使用电极表面的短暂电化学扰动，然后进行扫描探针显微镜表征来发展这种理解。
