The Macromolecular, Supramolecular and Nanochemistry (MSN) program of the Division of Chemistry will support the CAREER development plan of Prof. Stephan Link of the Department of Chemistry at William Marsh Rice University. Prof. Link and his students will combine novel single particle optical spectroscopy techniques with electron microscopy methods in order to understand the energy coupling between metal nanoparticles in close packed nanoparticle assemblies. Understanding the energy transfer in nanoparticle assemblies will ultimately determine the feasibility and aid in the development of cost-effective platforms for bottom-up chemical synthesis and self-assembly of nanoparticle-based functional materials such as antennas and waveguides, which are tolerant of variations in NP size, shape, and ordering. The PI and his students will connect their excitement about research and discovery in nanotechnology with outreach activities to educate K-12 students about nanotechnology and inspire them about careers in science related fields. Specifically, the PI will develop lectures for K-12 students on how NP size and shape is related to color and how this correlation is observed in an ensemble vs. single particle study. These lectures will be presented in the Civic Scientist Program at Rice University. The proposed project will provide excellent training opportunities to graduate students at the research frontier of physical sciences.

化学系的大分子、超分子和纳米化学（MSN）项目将支持William Marsh Rice大学化学系Stephan Link教授的职业发展计划。林克教授和他的学生将把新颖的单粒子光谱学技术与电子显微镜方法结合起来，以了解紧密排列的纳米粒子组件中金属纳米粒子之间的能量耦合。了解纳米粒子组件中的能量转移将最终决定可行性，并有助于开发具有成本效益的平台，用于自下而上的化学合成和基于纳米粒子的功能材料（如天线和波导）的自组装，这些材料可以容忍NP大小、形状和顺序的变化。PI和他的学生将把他们对纳米技术研究和发现的兴奋与外展活动联系起来，教育K-12学生纳米技术，并激励他们从事科学相关领域的职业。具体来说，PI将为K-12学生开发关于NP大小和形状如何与颜色相关的讲座，以及如何在整体与单粒子研究中观察到这种相关性。这些讲座将在莱斯大学的公民科学家项目中进行。本项目将为从事物理科学前沿研究的研究生提供良好的培训机会。
