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.

该奖项由主要的研究工具，既定的竞争研究计划（EPSCOR）和化学研究工具计划共同支持。北达科他大学（University of North Dakota）正在购买配备液氮冷却探针的400 MHz核磁共振（NMR）光谱仪，以支持对Guodong DU的研究，同事Mikhail Golovko，Alena Kubatova，Alena Kubatova，Chad Wocken和Feng Xiao。该光谱仪允许在各种领域进行研究，例如加速具有重要经济意义的化学反应的领域，并允许对化学和生物学相关物种进行研究。通常，核磁共振（NMR）光谱是化学家可用于阐明分子结构的最强大工具之一。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液中分子或固态中分子之间相互作用的动力学。该探针使用氮气冷却的射频线圈，具有极大增强的灵敏度。对于正在进行边境研究的化学家来说，使用最先进的NMR光谱仪至关重要。该乐器是该机构化学和生物化学的本科生和研究生的教学和研究培训的组成部分，该工具还将为部落学院和其他邻近机构的合作者提供服务。该奖项授予400 MHz NMR光谱仪，并在各个级别的研究中，在各个级别的研究中，都在各个级别的研究中，在各个级别的教育中，在各个级别的教育中（该大学）（该大学）（在各个级别的教育）（该大学）（该大学的教育）（该大学）（该大学）（该大学）（在各个方面都在大学教育，该公司（机构。预计将从该工具中尤其受益的研究项目包括从可再生资源合成的可生物降解材料的表征以及使用光能用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表征的仪器以及结构表征合成的氨基膦和相关的钯配体的仪器。此外，新的高场NMR仪器将允许使用混合等离子体和催化剂反应器将火炬气体转换为碳产品获得的物种，并协助研究人员开发和工程聚合物膜进行气体分离。该奖项反映了NSF的法定任务，并通过评估该基金会的智力效果，并通过评估了CRARITAIL和FROADIAL和FRODIAL和FRODIAL和FLOARITAIL和FLOCTIAL和FRODIAL和FRODIAL和FRODIAL和FROADIAL和FRODIAL和FROADIAL和FROADIAL和FRADIAL和FLOARITAIL和FLOARITIAL。
