Optical, Structural, and Dynamic Properties of Viscous Liquids, Glasses, and Crystalline Materials Under Extremes of Pressure and Temperature

将开发一个学术研究计划，旨在探索新的和有趣的热力学系统中重要凝聚态系统的基本性质，并将其整合到该大学研究生和本科生的教育经验中。将使用高压和强大的光学和光散射技术，对粘性液体玻璃形成系统的状态方程、光学性质、脆性和快慢松弛过程以及玻璃、晶体和聚合物材料的光学、机械和动态性质进行基础研究。该项目的学生将有机会在现有合作下访问埃克森美孚研究和工程实验室，进行高压粘度实验。与这项研究计划相关的是建立一个独特的光学材料生长和表征的高级本科实验室(部分正在开发中，获奖编号：DUE 9452409)。这个计划将有两个完整的相关部分：(I)开发一个旨在探索极高压力下液体和固体的基本性质的学术研究计划，以及(Ii)开发一个独特的光学材料生长和表征的高级本科实验室。这两个组件的一个共同主题是使用现代激光和光学技术。第一部分侧重于粘性液体和熔融聚合物的基础研究，以及它们在低温或高压下凝固成分子有序排列的结晶材料或排列随机的玻璃材料的方式。S第二部分将为理工科本科生提供使用现代设备进行材料研究的实践体验。这门实验课程将重点放在重要的半导体和光学材料上，作为培养材料生长技能和确定其物理、电学和光学性质的教育工具。本科生将参与这两个部件，研究生将有机会在现有合作下在埃克森研究和工程实验室进行高压粘度测量。***

w:\awards\awards96\career\0formca.doc 9624833 Oliver An academic research program aimed at exploring fundamental properties of important condensed matter systems in new and interesting thermodynamic regimes will be developed and integrated into the educational experiences of both graduate and undergraduate students at the University. Fundamental studies of the equations of state, optical properties, fragilities, and both fast and slow relaxation processes of viscous liquid glass- forming systems; and the optical, mechanical, and dynamic properties of glassy, crystalline, and polymeric materials will be conducted using both high-pressure and powerful optical and light scattering techniques. Students in this program will have an opportunity to conduct high-pressure viscosity experiments by visiting the Exxon Research and Engineering Laboratory under an existing collaboration. Integrally related to this research program will be the development of a unique upper level undergraduate laboratory for the Growth and Characterization of Optical Materials (which is being developed in part under NSF-ILI award number: DUE 9452409). %%% This program will have two integrally related components: (i) the development of an academic research program aimed at exploring fundamental properties of liquids and solids under extremely high pressure, and (ii) the development of a unique upper level undergraduate laboratory for the Growth and Characterization of Optical Materials. A common theme to both components is the use of modern laser and optical techniques. The first component focuses on fundamental studies of viscous liquids and melted polymers and the ways in which they solidify at low temperature or high pressure into either a crystalline material with an ordered arrangement of molecules or a glassy material where the arrangement is random. The s econd component will give undergraduate science and engineering students "hands-on" experiences, using modern equipment, with several aspects of materials research. This laboratory course will focus on important semiconducting and optical materials as educational vehicles for developing skills in growing materials and determining their physical, electrical, and optical properties. Undergraduates will be involved in both components and graduate students will have opportunities to conduct high-pressure viscosity measurements at the Exxon Research and Engineering Laboratory under an existing collaboration. ***
