With this award from the Major Research Instrumentation Program (MRI) and support from the Chemistry Research Instrumentation Program (CRIF), Professor Benjamin Keitz from the University of Texas Austin and colleague C. Grant Willson have acquired a 400 MHz NMR spectrometer equipped with solid state capabilities. This spectrometer allows research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, as well as the study of biologically relevant species. In general, Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the study of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the changing interactions between molecules in solution or in the solid state. The results from these NMR studies have an impact in synthetic organic/inorganic chemistry, materials chemistry and biochemistry. This instrument is located a general user facility managed by highly qualified scientists as an integral part of research, research training and teaching. The improved research infrastructure further enriches the research experience for economically disadvantaged and underrepresented minority students at the institution. It is used in collaborations with non-Ph.D.-granting universities in the Austin metropolitan area. Specifically, faculty engages with students at St. Edwards University and Huston-Tillotson University as part of existing UT-Austin outreach programs. Such collaborations facilitate the development of interactions where faculty and students from these universities visit UT-Austin to use the spectrometer. Overall, the solid state NMR spectromater improves UT-Austin's many successful diversity initiatives.The award is aimed at enhancing research and education at all levels, especially in: (a) gaining information on polymeric materials, (b) studying conjugated metallopolymers, (c) characterizing porous solids, (d) studying protein self-assembly in structured biomaterials, (e) enabling the design of surface-modified nanoparticles, (f) contributing to research in the geological sciences, and (g) helping prepare new pharmaceutical dosage forms.

在主要研究仪器计划（MRI）的这一奖项和化学研究仪器计划（CRIF）的支持下，德克萨斯大学奥斯汀分校的Benjamin Keitz教授和同事C。Grant Willson已经购买了一台配备固态功能的400 MHz NMR光谱仪。该光谱仪可用于各种领域的研究，例如加速具有重要经济意义的化学反应，以及生物相关物种的研究。一般来说，核磁共振（NMR）光谱是化学家研究分子结构的最有力的工具之一。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液或固态分子之间不断变化的相互作用。 这些NMR研究的结果对合成有机/无机化学、材料化学和生物化学产生了影响。该仪器位于由高素质科学家管理的一般用户设施，作为研究，研究培训和教学的组成部分。改进的研究基础设施进一步丰富了该机构经济困难和代表性不足的少数民族学生的研究经验。 它被用于与非博士合作-授予奥斯汀大都会区的大学。具体来说，教师与学生在圣爱德华兹大学和休斯顿-蒂洛森大学作为现有UT-奥斯汀外展计划的一部分。这种合作促进了互动的发展，来自这些大学的教师和学生访问UT-奥斯汀使用光谱仪。总的来说，固态NMR光谱仪改善了UT-奥斯汀的许多成功的多样性举措。该奖项旨在加强各级研究和教育，特别是在：（a）获得关于聚合物材料的信息，（B）研究共轭金属聚合物，（c）表征多孔固体，（d）研究结构化生物材料中的蛋白质自组装，（e）能够设计表面改性的纳米颗粒，（f）为地质科学研究作出贡献;及（g）协助制备新的药物剂型。
