0225578W。吉尔伯特克拉克描述：该奖项支持一项名为“通过核磁共振（NMR）研究导电聚合物的自旋和电荷动力学”的美国-印度合作研究项目。 美国PI W.吉尔伯特克拉克，加州洛杉矶大学（UCLA）将与雷古梅农和其他两名研究人员从总理印度科学研究所（IISc），班加罗尔。 目的是通过核磁共振测量研究导电聚合物中载流子的动力学。 他们将进行相关的电传输和电子自旋共振研究，并合成适当的样品。 这项研究将解决目前感兴趣的导电聚合物中电子传输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输机制的理解。 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、电输运以及超低温和高磁场下的测量方面拥有丰富的经验。 他的印度合作者拥有互补的专业知识，将在班加罗尔的IISc进行样品合成和明确的传输测量。 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。 这种合作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。 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。 该项目由印度科学技术部（DST）在NSF/DST计划下共同支持。

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.
