Professor Francis P. Zamborini of the University of Louisville is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to study the electrochemical reactivity and oxidation potential of silver and gold nanostructures as a function of size, shape, and surface chemistry. A second thrust of this supported research is to electrochemically synthesize Silver nanowires for sensing and molecular electronics applications. The proposed nanostructures will be characterized by spectroscopic, electrochemical and microscopic techniques. This research will lead to a better understanding of the effect of the size and shape of chemically and electrochemically synthesized nanostructures on the oxidation potential and the mechanisms of electron transfer at these nanoscale dimensions, which will push the field forward towards technological applications in miniaturized electronics, chemical sensing, and catalysis. Graduate and undergraduate students will participate in all aspects of the proposed research, and high school students will participate through outreach activities.

路易斯维尔大学的弗朗西斯P. Zamborini教授得到化学系分析和表面化学项目的支持，研究银和金纳米结构的电化学反应性和氧化电位与尺寸、形状和表面化学的关系。这项研究的第二个重点是电化学合成银纳米线用于传感和分子电子学应用。所提出的纳米结构将通过光谱、电化学和显微技术来表征。这项研究将导致更好地了解化学和电化学合成的纳米结构的尺寸和形状对氧化电位的影响以及这些纳米尺度下的电子转移机制，这将推动该领域在小型化电子，化学传感和催化方面的技术应用。研究生和本科生将参与拟议研究的各个方面，高中生将通过外联活动参与。
