MRI: Track 1 Acquisition of a 400 MHz NMR Spectrometer to Advance Research and Education at Multiple Undergraduate-Serving Institutions in Tacoma, Washington

该奖项由主要研究仪器和化学研究仪器计划共同支持。普吉特海湾大学正在购买一台配备宽带探头的400 MHz核磁共振（NMR）光谱仪，以支持Eric Scharrer教授沿着同事艾米丽Tollefson，Oscar Sosa，Luc Boisvert以及Kelly Kim教授的研究华盛顿大学塔科马分校（UWT）。该NMR光谱仪可用于材料科学、药物化学、催化、水环境科学、有机、无机和有机金属合成等领域的研究。一般来说，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。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。除了加强与这些教师合作的本科研究人员的培训外，该仪器还被广泛用作普吉特海湾，UWT和塔科马社区学院（TCC）化学和生物学教学和实验室课程的一部分。该仪器也提供给更大的塔科马科学界。授予核磁共振光谱仪的目的是加强各级的研究和教育。该仪器的研究重点是研究，制备和表征新的液晶化合物和有机和金属胶凝剂。它允许铋纳米颗粒以及医学和生物学相关化合物的研究和结构表征。它使研究和开发新的催化系统，以实现更可持续的合成，并有助于了解水生环境中膦酸盐的来源和命运。为了应对全球氦气供应的挑战，该仪器的采购包括一个超导磁体，其低损耗低温恒温器可减少该机构的氦气消耗。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 and the Chemistry Research Instrumentation programs. The University of Puget Sound is acquiring a 400 MHz nuclear magnetic resonance (NMR) spectrometer equipped with a broadband probe to support the research of Professor Eric Scharrer along with colleagues Emily Tollefson, Oscar Sosa, Luc Boisvert, and that of Professor Kelly Kim at the University of Washington - Tacoma (UWT). This NMR spectrometer facilitates research in a variety of fields, such as materials science, medicinal chemistry, catalysis, aquatic environmental science, and organic, inorganic, and organometallic synthesis. In general, 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. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. In addition to enhancing the training of undergraduate researchers working with these faculty members, the instrument is used extensively as part of a wide range of teaching and laboratory courses in both chemistry and biology at Puget Sound, UWT, and Tacoma Community College (TCC). The instrument is also available to the greater Tacoma scientific community.The award of the NMR spectrometer is aimed at enhancing research and education at all levels. Research enabled by the instrument is focused on the study, preparation, and characterization of new liquid crystalline compounds and organo- and metallo-gelators. It allows the study and structural characterization of bismuth nanoparticles, and of medicinally and biologically relevant compounds. It enables the study and development of new catalytic systems for more sustainable synthesis and helps in understanding the sources and fates of phosphonates in aquatic environments. In response to global helium supply challenges, the acquisition of this instrument includes a superconducting magnet with a low loss cryostat reducing the institution’s consumption of helium.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.
