MRI: Acquisition of a Solid-state-enabled Nuclear Magnetic Resonance (NMR) Spectrometer

在重大研究仪器计划(MRI)的这一奖项和化学研究仪器计划(CRIF)的支持下，迈阿密大学(UM)的Jamie WALLS教授及其同事Vaidhyanathan Ramamurthy和Burjor Capter获得了一台配备了固态功能的400 MHz核磁共振波谱仪。这种光谱仪允许在各种领域进行研究，例如那些加速具有重大经济意义的化学反应的领域，以及对生物相关物种的研究。总的来说，核磁共振波谱是化学家用来研究分子结构的最强大的工具之一。它被用来识别未知物质，表征分子中原子的特定排列，并研究分子在溶液或固体中变化的相互作用。这些核磁共振研究的结果对合成有机/无机化学、材料化学和生物化学都有影响。该仪器位于由高素质科学家管理的通用用户设施中，是研究、研究培训和教学不可或缺的一部分。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族裔高中生的研究经验，这些学生参加了化学系内的UM桥项目。此外，该光谱仪还提供固态核磁共振和显微成像功能，这是南佛罗里达州所不具备的。该仪器的使用促进了密歇根大学与当地工业、学院和大学之间的合作。该奖项旨在加强各级的研究和教育，特别是在以下方面：(A)研究作为多相催化剂的三金属纳米团簇；(B)研究固体表面和晶体上官能化的超分子主客体络合物；(C)分析偶极和四极耦合自旋系统中的自旋动力学；(D)表征过氧碳酸盐的形成；以及(E)获得生物组织样品的直接代谢图谱。

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.
