Self-diffusion in supercooled liquids and glasses

该奖项由化学系实验物理化学计划资助，威斯康星州大学的Mark Ediger教授和他的研究生将继续研究低分子量玻璃形成材料的自扩散速率。 这将通过实验技术的组合来实现，包括中子反射率和热程序解吸测量。 关于物质的玻璃态还有很多未知之处，Ediger教授和他的同事们将进行实验，以帮助区分许多理论模型。 物质的玻璃态有许多有用的技术应用：从制造更好的玻璃材料到开发改进的药物配方。Ediger教授和他的学生同事将继续参与威斯康星州的人民计划，在夏季为来自科学代表性不足的群体的高中毕业生提供丰富的教育。

In this award, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Mark Ediger of the University of Wisconsin and his graduate research students will continue their work studying self-diffusion rates in low molecular weight glass-forming materials. This will be achieved through a combination of experimental techniques, including neutron reflectivity and thermally-programmed desorption measurements. Much is still unknown about the glassy state of matter, and Prof. Ediger and his colleagues will carry out experiments that should help differentiate among a number of theoretical models. The glassy state of matter has a number of useful technological applications: from the fabrication of better glass materials to the development of improved formulations for pharmaceuticals. Besides the broader technological impacts of the research being supported, Prof. Ediger and his student colleagues will continue their involvement in the University of Wisconsin's PEOPLE Program, providing educational enrichment in the summer for high school sophomores from groups under-represented in the sciences.
