项目摘要

With this award from the Major Research Instrumentation Program (MRI) and support from the Chemistry Research Instrumentation Program (CRIF), Professor Jamie Walls from the University of Miami (UM) and colleagues Vaidhyanathan Ramamurthy and Burjor Captain have acquired a 400 MHz NMR spectrometer equippped 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 in a general user facility managed by highly qualified scientists is an integral part of research, research training and teaching. The improved research infrastructure further enriches the research experience for economically disadvantaged and underrepresented minority high school students in Miami-Dade county that participate in UM bridge programs within the Chemistry Department. Additionally, the spectrometer provides solid-state NMR and microimaging capabilities that had been unavailable in South Florida. Access to the instrument fosters collaborations between UM and local industries, colleges and universities.The award is aimed at enhancing research and education at all levels, especially in: (a) investigating trimetallic nanoclusters incorporated as heterogeneous catalysts; (b) studying supramolecular host/guest complexes functionalized on solid surfaces and crystals; (c) analyzing spin dynamics in dipolar and quadrupolar coupled spin systems; (d) characterizing the formation of peroxycarbonates, and (e) obtaining the direct metabolic profiling of biological tissue samples.

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，来自迈阿密大学（UM）的Jamie Walls教授及其同事Vaidhyanathan Ramamurthy和Burjor Captain获得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中，是研究，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迈阿密-戴德县经济困难和代表性不足的少数民族高中学生的研究经验，这些学生参加了化学系内的UM桥梁项目。此外，光谱仪提供了固态核磁共振和显微成像能力，这在南佛罗里达是不可用的。该奖项旨在加强各级研究和教育，特别是在：（a）研究作为非均相催化剂的三金属纳米团簇;（B）研究在固体表面和晶体上官能化的超分子主体/客体复合物;（c）分析偶极和四极耦合自旋系统中的自旋动力学;（d）研究作为非均相催化剂的三金属纳米团簇。（d）表征过氧碳酸盐的形成，和（e）获得生物组织样品的直接代谢谱。
