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.

该奖项由化学系实验物理化学项目资助，俄亥俄州州立大学的Philip Grandinetti教授、他的博士后研究员和研究生将继续致力于开发用于分析无序固体结构和组成的核磁共振（NMR）方法。他们的努力将集中在改进Grandinetti实验室早期开发的旋转共振技术，以及开发使用氧-17同位素作为探针确定氧配位数的方法。新的NMR方法将用于确定各种硅酸盐玻璃组合物中的结构分布。玻璃的分子结构和物理性质之间的关系是一个重要的技术问题，但目前还没有得到很好的理解。 Grandinetti教授的研究将有助于理解这些关系，不仅在玻璃材料中，而且在一般的无序固体中。 除了其更广泛的技术影响外，支持的研究还将提供广泛学科的本科生和研究生培训，包括材料科学，计算机编程以及仪器设计和制造。
