NMR Methods for Determining Structure in Oxide Glasses

这一奖项由化学系实验物理化学项目资助，俄亥俄州立大学教授菲利普·格兰迪内蒂、他的博士后和研究生将继续他们的工作，开发用于分析无序固体结构和组成的核磁共振(核磁共振)方法。他们的努力将集中在改进格兰迪内蒂实验室早些时候开发的旋转共振技术，以及开发使用氧-17同位素作为探针来确定氧配位数的方法。然后，新的核磁共振方法将用于确定各种硅酸盐玻璃成分中的结构分布。玻璃的分子结构和物理性能之间的关系是一个重要的技术问题，但目前还没有被很好地理解。格兰迪内蒂教授的研究将有助于理解这些关系，不仅是在玻璃材料中，而且在一般的无序固体中。除了其更广泛的技术影响外，所支持的研究还将为本科生和研究生提供广泛学科的培训，包括材料科学、计算机编程以及仪器设计和制造。

In this award, funded by the Experimental Physical Chemistry program of the Chemistry Division, Professor Philip Grandinetti of the Ohio State University, his post-doctoral fellow and graduate students will continue their work on the development of nuclear magnetic resonance (NMR) methods for the analysis of the structure and composition of disordered solids. Their efforts will focus on the refinement of the rotary resonance technique developed earlier in the Grandinetti laboratory, and development of methods to determine oxygen coordination number using the oxygen-17 isotope as a probe. The new NMR methods will then be used to determine the distribution of structures in various silicate glass compositions. The relationship between the molecular structure and physical properties of glasses is an important technological issue, but is not currently well understood. Professor Grandinetti's research will contribute to the understanding of these relationships, not only in glassy materials but in disordered solids in general. In addition to its broader technological impacts, the supported research will also provided for the training of undergraduates and graduates in a wide range of disciplines, including materials science, computer programming, as well as instrument design and fabrication.
