The research to be conducted by Professor Cynthia Zoski at her research laboratories at the New Mexico State University, and supported by the Analytical and Surface Chemistry (ASC) Program in the Division of Chemistry, will study how nanoparticles interact with metal surfaces and various types of support platforms and to provide wide-ranging knowledge on the relationship between nanoparticle size and its catalytic activity. An innovative aspect of the research is the use of addressable nanoelectrode membrane arrays to control the number and size of nanoparticles deposited/attached onto each contact electrode with subsequent measurement of the corresponding voltammetric profles in different reaction media by scanning electrochemical microscopy. Zoski's research will provide vital knowledge to understanding the electrocatalytic activities of nanoparticles in reactions of relevance to fuel cell chemistry, molecular recognition, sensing, drug delivery, and other such areas. Post-doctoral fellows and graduate students involved in the research will gain knowledge and training in state-of-the-art nanotechnology research, and will be involved in aspects of the project ranging from writing research papers, to disseminating experimental results at scientific and educational conferences, and training undergraduate students in basic chemical research methods.

这项研究将由 Cynthia Zoski 教授在新墨西哥州立大学的研究实验室进行，并得到化学系分析和表面化学 (ASC) 项目的支持，将研究纳米颗粒如何与金属表面和各种类型的支撑平台相互作用，并提供有关纳米颗粒尺寸与其催化活性之间关系的广泛知识。该研究的一个创新方面是使用可寻址纳米电极膜阵列来控制沉积/附着到每个接触电极上的纳米颗粒的数量和尺寸，随后通过扫描电化学显微镜测量不同反应介质中相应的伏安曲线。 Zoski 的研究将为理解纳米粒子在燃料电池化学、分子识别、传感、药物输送和其他领域相关反应中的电催化活性提供重要知识。参与该研究的博士后和研究生将获得最先进的纳米技术研究的知识和培训，并将参与该项目的各个方面，从撰写研究论文，到在科学和教育会议上传播实验结果，以及培训本科生基本化学研究方法。
