MRI: Acquisition of a 400 MHz NMR Spectrometer for Research and Research Training

该奖项由主要研究仪器和化学研究仪器计划支持。 圣劳伦斯大学正在购买一台400 MHz核磁共振光谱仪（NMR），以支持Adam Hill教授及其同事Samuel Tartakoff和阿曼达Oldacre团队的研究。该光谱仪可用于各种领域的研究，例如加速具有重要经济意义的化学反应，以及生物相关物种和环境化学的研究。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。该仪器是圣劳伦斯大学和附近机构（包括SUNY Canton和SUNY波茨坦）化学和生物化学本科生教学、研究和研究培训不可或缺的一部分。授予NMR光谱仪的目的是加强各级的研究和教育。它特别影响有机化学项目，特别是天然产物表征，小分子合成和方法开发。 无机材料化学研究涉及制备有用的异质结器件作为人工光合作用的潜在工具，以及金属有机框架作为降解有机污染物的催化剂。其他材料科学研究正在进行中的铈纳米粒子用于清除生理上有害的自由基和聚砜的结构特性的交联聚合物的应用。 目前正在研究微塑料特性等环境科学项目，以便对环境污染进行可能的补救。 目前正在进行研究，以了解DNA与消毒剂抑菌剂结合的效力。具有双折射特性的脂多糖正在被研究作为可能的生物传感器。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 supported by the Major Research Instrumentation and Chemistry Research Instrumentation Programs. St. Lawrence University is acquiring a 400 MHz nuclear magnetic resonance spectrometer (NMR) to support the research in the groups of Professor Adam Hill and colleagues Samuel Tartakoff and Amanda Oldacre. This spectrometer enables research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, as well as the study of biologically relevant species and environmental chemistry. In general, NMR spectroscopy is one of the most powerful tools available for chemists to elucidate 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 for chemists who are carrying out frontier research. This instrument is an integral part of teaching as well as research and research training of undergraduate students in chemistry and biochemistry at St. Lawrence University and nearby institutions including SUNY Canton and SUNY Potsdam. The award of the NMR spectrometer is aimed at enhancing research and education at all levels. It especially impacts organic chemistry projects, particularly natural products characterization, small-molecule synthesis, and methods development. Inorganic materials chemistry investigations involve preparing useful heterobimetallic devices as potential tools for artificial photosynthesis and also metal organic frameworks used as catalysts for the degradation of organic pollutants. Other materials science research is ongoing of cerium nanoparticles for scavenging physiologically damaging free radicals and the structural properties of polysulfones for crosslinking polymer applications. Environmental science projects such as the characterization of microplastics are under study for possible remediation of environmental contamination. Research to understand the efficacy of DNA-binding with disinfectant bacteriostatics is being carried out. Lipoppolysaccharides with birefringence properties are being studied as possible biosensors.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.
