0225578 w。该奖项支持美印合作研究项目，题为核磁共振（NMR）研究导电聚合物中的自旋和电荷动力学。美国加州大学洛杉矶分校（UCLA）的PI W. Gilbert Clark将与Reghu Menon和另外两名来自班加罗尔印度科学研究所（IISc）的科学家合作。目的是通过核磁共振测量来研究导电聚合物中载流子的动力学。他们将进行相关的电输运和电子自旋共振研究，并合成适当的样品。这项研究将解决当前人们感兴趣的导电聚合物中电子传递机制的许多关键问题，如无序的长度尺度和金属-绝缘体转变的性质。最终的研究目标是增加对这些材料中电子传递机制的理解。研究范围：克拉克教授是应用核磁共振技术研究导电分子晶体和固体性质的知名专家。他在核磁共振、电传输以及超低温和高磁场下的测量方面拥有丰富的经验。他的印度合作者将在班加罗尔的IISc进行样品合成和明确的运输测量。pi将使用加州大学洛杉矶分校的设施、塔拉哈西的国家高磁场实验室和法国的格勒诺布尔高磁场实验室。这次合作充分利用了克拉克和梅农之间的协同作用，梅农在加州大学洛杉矶分校担任博士后期间首次建立了合作关系。该项目将为加州大学洛杉矶分校的博士后和研究生提供国际经验，并将加强加州大学洛杉矶分校和印度科学院之间的合作。该项目由印度科学技术部（DST）在NSF/DST计划下联合支持。

0225578W. Gilbert ClarkDescription: This award supports a US-India cooperative research project entitled Spin and Charge Dynamics in Conducting Polymers by Nuclear Magnetic Resonance (NMR) Studies. US PI W. Gilbert Clark, University of California Los Angeles (UCLA) will collaborate with Reghu Menon and two other researchers from the premier Indian Institute of Science (IISc), Bangalore. The objective is to investigate the dynamics of charge carriers in electrically conducting polymers by NMR measurements. They will carry out related electrical transport and electron spin resonance studies and synthesis of the appropriate samples. This research will address many key questions on the mechanisms for electron transport in conducting polymers that are of current interest such as the length scale of disorder and nature of the metal-insulator transition. The ultimate research goal is to increase understanding of the mechanisms for electron transport in these materials. Scope: Professor Clark is a well-known expert in applying the NMR technique to study properties of conducting molecular crystals and solids. He has extensive experience with NMR, electrical transport, and measurements at ultra-low temperatures and high magnetic fields. His Indian collaborators, who have complimentary expertise, will carry out sample synthesis and well-defined transport measurements at the IISc, Bangalore. The PIs will use UCLA facilities, the National High Magnetic Field Laboratory in Tallahassee, and the Grenoble High Magnetic Field Laboratories in France. This collaboration takes advantage of a synergy between Clark and Menon first established during Menon's tenure at UCLA as a post doc. This project will provide an international experience for a UCLA postdoc and graduate student, and will enhance collaboration between UCLA and the IISc. This project is jointly supported by the Indian Department of Science & Technology (DST) under the NSF/DST program.
