9615767 Dufty Description: This is a U.S.-India research collaboration entitled Metastable State Dynamics for Hard Spheres. The project is under the direction of James W. Dufty, University of Florida and Shankar P. Das, Jawaharlal Nehru University, New Delhi. The investigators will study the long-standing problem of describing glass formation and the properties of glasses. Their objectives are to identify qualitative mechanisms responsible for very slow dynamics and to develop practical methods for quantitative analysis. They will limit their study to the idealized hard sphere system in order to take advantage of recent developments which permit accurate theoretical analyses of the dynamics in both dense fluid and crystal phases, not available for any other atomic or molecular systems. These prototype studies will address some of the most basic questions relevant to glass formation and their properties. Glasses and related composites play an essential role in the development of new materials in a wide range of applications. Scope: This collaboration is driven by the research interests of two highly competent investigators who have worked together on closely related research for the past six years. The unique approach they have developed for solving a significant problem has excellent potential for scientific breakthrough. The support requested is primarily for travel and per diem. Postdocs and graduate students involved in the program will be supported by their respective institutions. ***

9615767 Dufty 描述：这是一项美印合作研究，题为“硬球的亚稳态动力学”。 该项目由佛罗里达大学 James W. Dufty 和新德里贾瓦哈拉尔尼赫鲁大学 Shankar P. Das 指导。 研究人员将研究描述玻璃形成和玻璃特性的长期存在的问题。 他们的目标是确定导致非常缓慢的动力学的定性机制，并开发定量分析的实用方法。 他们将把他们的研究限制在理想化的硬球系统上，以便利用最近的发展，这些发展允许对致密流体和晶体相的动力学进行精确的理论分析，这是任何其他原子或分子系统所无法实现的。 这些原型研究将解决一些与玻璃形成及其特性相关的最基本问题。 玻璃和相关复合材料在广泛应用的新材料开发中发挥着重要作用。 范围：本次合作是由两位高素质研究人员的研究兴趣推动的，他们在过去六年中共同致力于密切相关的研究。 他们为解决重大问题而开发的独特方法具有巨大的科学突破潜力。 请求的支持主要用于差旅费和每日津贴。 参与该计划的博士后和研究生将得到各自机构的支持。 ***
