This award is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. Johns Hopkins University is acquiring a 500 MHz nuclear magnetic resonance (NMR) spectrometer equipped with solid state capabilities and other probes to support Professor Rebekka Klausen and colleagues Howard Fairbrother, Sara Thoi and Adelina Voutchkova-Kostal from George Washington University. This spectrometer allows research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, as well as permitting study of biologically relevant species. 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. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution and nearby universities such as Georgetown University and the US Naval Academy. The instrument is also used on university NMR Summer School and in collaboration with museums to study cultural heritage materials.The award of the NMR spectrometer is aimed at enhancing research and education at all levels. It especially impacts spectroscopic studies of polymeric materials based on main group elements. The instrumentation is also used for studying supramolecular materials as well as analyzing conjugated polymer blends and surface-immobilized polymers. In addition, it provides information for exploring biodegradable polymer-functionalized nanocellulose composites and for the study of cultural-heritage materials. The spectrometer is also used to identify phosphorus(III)-oxyanions relevant to agriculture and food safety.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.

该奖项由主要研究仪器和化学研究仪器计划支持。约翰霍普金斯大学正在购买一台500 MHz核磁共振（NMR）光谱仪，配备固态功能和其他探头，以支持乔治华盛顿大学的Rebekka Klausen教授及其同事霍华德费尔布罗泽、Sara Thoi和Adelina Voutchkova-Kostal。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，以及允许研究生物相关物种。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。该仪器是该机构和附近大学（如乔治敦大学和美国海军学院）化学和生物化学本科生和研究生教学、研究和研究培训的一个组成部分。该仪器还用于大学NMR暑期学校，并与博物馆合作研究文化遗产材料。授予NMR光谱仪的目的是加强各级的研究和教育。它特别影响基于主族元素的聚合物材料的光谱研究。该仪器还用于研究超分子材料以及分析共轭聚合物共混物和表面固定化聚合物。此外，它还为探索可生物降解的聚合物功能化纳米纤维素复合材料和文化遗产材料的研究提供了信息。该光谱仪还用于鉴定与农业和食品安全相关的磷（III）-含氧阴离子。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。
