With this award, the Chemical Structure, Dynamics, and Mechanisms Program supports Professor Shaowei Chen of the University of California-Santa Cruz in a project involving the synthesis and characterization of transition metal nanoparticles whose surface is capped by organic molecules covalently-bonded to the metal. The goal of the project is to provide increased understanding of electrical connectivity across the metal-organic junction in capped transition metal nanoparticles. To this end, a range of carbon-capped transition metal nanoparticles will be synthesized and studied in order to assess the effects of interfacial contacts, core size, and the structure of the organic ligand on nanoparticle electronic conductivity. These investigations will provide mechanistic insights into nanoparticle charge transfer dynamics that will impact a variety of applications including areas related to energy conversion, nanoelectronics, and catalysis. This project, which combines chemistry and material science, will train graduate and undergraduate students in the techniques of nanoscience to include the synthesis, characterization and manipulation of nanoparticles.

获得该奖项的化学结构、动力学和机制计划支持加州大学圣克鲁斯分校的陈少伟教授参与的一个项目，该项目涉及过渡金属纳米颗粒的合成和表征，其表面由与金属共价键合的有机分子覆盖。该项目的目标是提高对带帽过渡金属纳米颗粒中金属-有机结电连接的理解。为此，我们将合成和研究一系列碳封端的过渡金属纳米粒子，以评估界面接触、核尺寸和有机配体的结构对纳米粒子电子导电性的影响。这些研究将提供对纳米粒子电荷转移动力学的机械见解，这些动力学将影响各种应用，包括与能量转换、纳米电子学和催化相关的领域。这个项目结合了化学和材料科学，将培训研究生和本科生纳米科学技术，包括纳米颗粒的合成、表征和操作。
