MRI: Acquisition of a 400 MHz NMR Spectrometer for Research and Research Training

该奖项由主要研究仪器，刺激竞争性研究的既定计划（EPSCoR）和化学研究仪器计划共同支持。北达科他州大学正在购买一台配备液氮冷却探头的400 MHz核磁共振（NMR）光谱仪，以支持Guodong Du及其同事Mikhail Golovko，Alena Kubatova，Chad Wocken和Feng Xiao的研究。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，以及允许研究化学和生物学相关物种。一般来说，核磁共振（NMR）光谱是化学家用来阐明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相互作用的动力学。探头使用氮气冷却的射频线圈，提供大大增强的灵敏度。对于从事前沿研究的化学家来说，使用最先进的NMR光谱仪是必不可少的。该仪器是该机构化学和生物化学本科生和研究生的教学、研究和研究培训的一个组成部分，该仪器还将为部落学院和其他邻近机构的合作者提供服务。该400 MHz NMR光谱仪与灵敏度增强冷冻探针的奖项旨在加强北达科他州大学各级的研究和教育（和合作机构。UND的研究项目预计将特别受益于这一工具，包括从可再生资源合成的可生物降解材料的表征和使用光能从可再生材料制备的二维聚合物材料的构建。木质素及其降解产物的表征以及合成的氨基膦和相关的双齿钯配体的结构表征的仪器。此外，新的高场核磁共振仪器将允许通过使用混合等离子体和催化剂反应器将火炬气转化为碳产品所获得的物种的表征，并帮助研究人员开发和工程化用于气体分离的聚合物膜。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award is jointly supported by the Major Research Instrumentation, the Established Program to Stimulate Competitive Research (EPSCoR) and the Chemistry Research Instrumentation programs. The University of North Dakota is acquiring a 400 MHz nuclear magnetic resonance (NMR) spectrometer equipped with liquid nitrogen cooled probe to support research of Guodong Du and colleagues Mikhail Golovko, Alena Kubatova, Chad Wocken, and Feng Xiao. This spectrometer allows research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, as well as permitting study of chemically and biologically relevant species. In general, Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution or in the solid state. The probe uses nitrogen-cooled radiofrequency coils that deliver greatly enhanced sensitivity. Access to a state-of-the-art NMR spectrometer is essential to chemists who are carrying out frontier research. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution and the instrument will also serve collaborators from tribal colleges and other neighboring institutions.This award of a 400 MHz NMR spectrometer with sensitivity-enhancing cryoprobe is aimed at enhancing research and education at all levels at the University of North Dakota (UND) and at collaborating institutions. Research projects at UND that is expected to especially benefit from this instrument include the characterization of biodegradable materials synthesized from renewable resources and the construction of two-dimensional polymeric materials prepared from renewable materials using photo-energy. The instrumentation for the characterization of lignin and its degradation products as well as to structurally characterize synthesized aminophosphines and related bidentate ligands for palladium. In addition, the new high field NMR instrument will allow for the characterization of species obtained by converting flare gas to carbon products using hybrid plasma and catalyst reactors and to assist researchers in developing and engineering polymeric membranes for gas separation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
