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项目和化学研究仪器项目共同支持。普吉特海湾大学正在获取一台配备宽带探头的400 MHz核磁共振(核磁共振)光谱仪，以支持Eric Scharrer教授及其同事Emily Tollefson、Oscar Sosa、Luc Boisvert和华盛顿大学塔科马分校(UWT)Kelly Kim教授的研究。该核磁共振光谱仪可促进各种领域的研究，如材料科学、药物化学、催化、水环境科学以及有机、无机和有机金属合成。总体而言，核磁共振波谱是化学家用于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。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。除了加强与这些教员合作的本科生研究人员的培训外，该仪器还被广泛用作普吉特湾、威斯康星州大学和塔科马社区学院(TCC)广泛的化学和生物教学和实验室课程的一部分。该仪器也适用于塔科马科学界。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新型液晶化合物以及有机和金属凝胶剂的研究、制备和表征。它允许研究和表征铋纳米颗粒，以及与医学和生物相关的化合物。它有助于研究和开发新的催化系统，以实现更可持续的合成，并有助于了解水环境中磷酸盐的来源和命运。作为对全球氦供应挑战的回应，这台仪器的收购包括一个具有低损耗低温恒温器的超导磁体，减少了机构的氦消耗。这项奖励反映了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。

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.
