MRI-Acquisition: 400 MHz NMR Spectrometer including PFG/HRMAS for Materials Chemistry Research: The Missing Instrument

有了这项来自重大研究仪器计划的奖项，来自南达科他州大学的Andrew Sykes教授及其同事Paul May、Grigoriy Sereda和Ranjit Koodali将获得一台具有固态功能的400 MHz NMR光谱仪，该光谱仪配备了脉冲场梯度（PFG）、高灵敏度液体探针（用于1H、13 C、19 F和31 P核）、用于液体样品的高分辨率魔角旋转（HRMAS）探头、可变温度（VT）能力和自动样品更换器。该提案旨在加强各级的研究培训和教育，特别是在以下领域：（a）用于生物和材料应用的发光纳米材料;（B）用于药物输送的量子点的衍生化;（c）受抑刘易斯对的反应性;（d）周期性立方介孔材料形成机制的研究;（e）使用碳质催化剂的绿色化学;（f）用于光催化分解水的有机纳米组件;（g）用于空气稳定和防潮的柔性光电子学的氟化材料;（h）荧光传感器的金属有机化学;和（i）基于硫杂杯芳烃的金属有机笼作为人工受体。核磁共振（NMR）光谱学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，并研究溶液中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。这些NMR研究的结果将对合成有机/无机化学、材料化学和生物化学产生影响。该仪器将成为南达科他州大学以及南达科他州州立大学（SDSU）和南达科他州矿业与技术学院（SDSM T）教学和研究的组成部分。该工具还将通过“北方平原REU网站：满足区域部落学院和初级本科院校的需求”，广泛用于教育和培训服务不足的群体，包括部落和小型农村学院的学生和教师。

With this award from the Major Research Instrumentation Program, Professor Andrew Sykes from University of South Dakota and colleagues Paul May, Grigoriy Sereda and Ranjit Koodali will acquire a 400 MHz NMR spectrometer with solid state capabilities equipped with a pulsed field gradient (PFG), high sensitivity liquid probe (for 1H, 13C, 19F, and 31P nuclei), a high resolution magic angle spinning (HRMAS) probe for liquid samples, variable temperature (VT) capability, and an automatic sample changer. The proposal is aimed at enhancing research training and education at all levels, especially in areas such as (a) luminescent nanomaterials for biological and materials applications; (b) derivatization of quantum dots for drug delivery; (c) reactivity of frustrated Lewis pairs; (d) study of the mechanism of formation ofperiodic cubic mesoporous materials; (e) green chemistry using carbonaceous catalysts; (f) organic, nano-assemblies for photocatalytic water splitting; (g) fluorinated materials for air-stable and moisture-resistant flexible optoelectonics; (h) metal-organic chemistry of fluorescence sensors; and (i) thiacalixarene based metal-organic cages as artificial receptors.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. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have an impact in synthetic organic/inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research at the University of South Dakota but also at South Dakota State University (SDSU) and South Dakota School of Mines and Technology (SDSM&T). The instrument will also be used extensively in the education and training of underserved groups, including students and faculty at tribal and small rural colleges through The Northern Plains REU Site: Serving the Needs of Regional Tribal Colleges and Primary Undergraduate Institutions.
