Professor Shaowei Chen is supported by the NSF Analytical and Surface Chemistry program to study the electron transfer properties of nanoparticle solid films. In this project, the focus will be on electrochemical studies of monolayers of organically capped nanoparticles which will be prepared either directly at the air|water interface by the Langmuir method or by deposition onto an electrode surface by the Langmuir-Blodgett technique. In these studies, the interparticle separations will be deliberately varied and their effects on the ensemble electronic conductivity properties will be carefully and systematically examined. The direct correlation between the ensemble structures and electron-transfer properties will then be exploited to identify and optimize related structural parameters so that single electron transfer in nanoparticle solid assemblies can be achieved. The fundamental insights that are obtained here may serve as the fundamental basis for the development of nanoparticle-based single electron transistors. These research activities will be integrated closely with several outreach programs specifically targeting disadvantaged or underrepresented students.

Shaowei Chen教授由NSF分析和表面化学计划支持，研究纳米颗粒固体膜的电子转移特性。 在这个项目中，重点将放在电化学研究的单层有机封端的纳米粒子，将直接在空气中制备，|水界面上或通过Langmuir-Blodgett技术沉积到电极表面上。 在这些研究中，粒子间的分离将被故意改变，它们对系综电子电导率特性的影响将被仔细和系统地检查。 然后，将利用系综结构和电子转移性质之间的直接相关性来识别和优化相关的结构参数，从而可以实现纳米颗粒固体组装体中的单电子转移。 在这里获得的基本见解可以作为基于纳米颗粒的单电子晶体管的发展的根本基础。 这些研究活动将与专门针对弱势或代表性不足的学生的几个外展计划紧密结合。
