0225578W。Gilbert ClarkDescription：该奖项支持美国和印度的一个合作研究项目，名为“核磁共振研究导电聚合物中的自旋和电荷动力学”。加州大学洛杉矶分校(UCLA)的美国人Pi W.Gilbert Clark将与Reghu Menon和班加罗尔首屈一指的印度科学研究所(IISc)的另外两名研究人员合作。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子传输和电子自旋共振研究，并合成适当的样品。这项研究将解决导电聚合物中电子传输机制的许多当前感兴趣的关键问题，如无序的长度、规模和金属-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输机制的了解。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著名专家。他在核磁共振、电子传输以及超低温和强磁场下的测量方面拥有丰富的经验。他的印度合作者拥有互补的专业知识，他们将在班加罗尔的IISC进行样品合成和明确定义的运输测量。PIS将使用加州大学洛杉矶分校的设施、塔拉哈西的国家强磁场实验室和法国的格勒诺布尔强磁场实验室。这一合作利用了克拉克和梅农在梅农担任加州大学洛杉矶分校博士后期间首次建立的协同效应。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IISC之间的合作。该项目由印度科学与技术部(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.
