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.

该奖项由重大研究仪器、既定的激励竞争研究计划(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(核磁共振)光谱仪，以支持杜国栋及其同事米哈伊尔·戈洛夫科、阿莱娜·库巴托娃、查德·沃肯和冯晓的研究。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，以及允许研究化学和生物相关的物种。总的来说，核磁共振波谱是化学家用来阐明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相互作用的动力学。该探头使用氮气冷却的射频线圈，大大提高了灵敏度。对于正在进行前沿研究的化学家来说，获得最先进的核磁共振光谱仪是必不可少的。该仪器是该机构本科生和研究生在化学和生物化学方面的教学、研究和研究培训的组成部分，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。此次授予具有灵敏度增强的低温探头的400 MHz核磁共振谱仪旨在加强北达科他州大学(UND)和合作机构各级的研究和教育。预计将特别受益于该文书的联合国开发计划署的研究项目包括利用可再生资源合成的可生物降解材料的特性，以及利用光能由可再生材料制备的二维聚合物材料的建造。用于表征木质素及其降解产物以及对合成的氨基膦和相关的钯的双齿配体进行结构表征的仪器。此外，新的高场核磁共振仪器将允许对使用混合等离子体和催化剂反应堆将耀斑气体转化为碳产品所获得的物种进行表征，并帮助研究人员开发和设计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智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
