Acquisition of a Solids NMR Spectrometer

该主要研究仪器奖为肯塔基大学化学系购买一台400 MHz核磁共振（NMR）固体光谱仪提供了资金。该仪器将极大地促进校园内现有的研究活动，并为校园内的研究人员、与当地大学和工业界的研究人员之间的合作创造新的机会。在过去的十年里，肯塔基大学在化学、生物化学和材料科学方面发展了蓬勃的项目，这些项目正在推动校园内可用仪器的极限。该仪器的主要研究领域包括：1)有机固体-固体核磁共振将用于探测碳纳米管的结构和包含这些纳米管的新型复合材料。这种仪器可以探测这些令人兴奋的化合物的电子态。2)主基团有机金属材料-固态核磁共振将用于探测氧化铝的结构，形成一个新的相对低温的过程。这些数据对于充分了解这种材料、进一步优化前体以及未来的应用至关重要。3)高分子材料——固态核磁共振将用于研究碳化硅材料的前体——聚碳硅烷。了解这些超支化聚合物的结构将有助于设计更好的碳化硅前驱体。4)生物结构——在酶的固态光谱中测量的共振的化学位移各向异性将用于进一步了解蛋白质基质如何影响辅助因子（如黄素）的反应性。该核磁共振光谱仪的收购由主要研究仪器计划资助，将提供肯塔基大学目前无法获得的能力，并将加强重要新兴材料化学领域的研究。它还将为校园内不同院系的研究人员、与当地大学（包括一所当地少数族裔大学）以及与工业界的合作创造新的机会。此外，不仅与pi一起工作的学生将接受该仪器的培训，而且该大学的研究生和高级本科化学学生也将接受该仪器的培训，作为光谱学课程的一部分。因此，该仪器将对肯塔基大学材料化学研究的基础设施产生重大影响。

9977388MeierThis Major Research Instrumentation award provides funding for the acquisition of a 400 MHz nuclear magnetic resonance (NMR) spectrometer for solids in the Chemistry Department at the University of Kentucky. The instrument will greatly facilitate the existing research activity on campus as well as create new opportunities for collaboration between researchers on campus, with local colleges, and with industry. Vigorous programs in chemistry, biological chemistry, and materials science have developed at the University of Kentucky in the past 10 years that are pushing the limits of the instrumentation available on campus. The major research areas to be undertaken with this newly acquired instrument include the following: 1) Organic Solids - solid-state NMR will be used to probe the structure of carbon nanotubes and new composite materials incorporating these nanotubes. This instrumentation will allow the probing of the electronic states of these exciting compounds. 2) Main Group Organometallic Materials -solid-state NMR will be used to probe the structure of alumina, formed by a novel relatively low-temperature process. The data will be essential for a full understanding of this material, for further optimization of the precursors, and for future applications. 3) Polymeric Materials - solid-state NMR will be used to study polycarbosilanes, which are precursors to silicon carbide materials. An understanding of the structure of these hyperbranched polymers will facilitate design of better SiC precursors. 4) Biological Structures - the chemical shift anisotropy of resonances measured in the solid-state spectra of enzymes will be used to further understanding of how a protein matrix affects the reactivity of cofactors such as flavin.The acquisition of this nuclear magnetic resonance spectrometer, funded by the Major Research Instrumentation Program, will provide capabilities not currently available at the University of Kentucky and will enhance research in important emerging materials chemistry areas. It will also create new opportunities for collaboration between researchers in different departments on campus, with local colleges, including a local minority institution, and with industry. In addition, not only the students working with the PIs will be trained on this instrument, but graduate and advanced undergraduate Chemistry students at the university will be trained on the instrument as part of a course on spectroscopy. Thus this instrument will have a large impact on the infrastructure for materials chemistry research at the University of Kentucky.
