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.

该奖项得到了主要的研究工具和化学研究工具计划的支持。约翰·霍普金斯大学（Johns Hopkins University）正在收购配备固态功能和其他探针的500 MHz核磁共振仪（NMR）光谱仪，以支持Rebekka Klausen教授和同事Howard Fairbrother，Sara Thoi和Adelina Voutchkova-Kostal，来自乔治华盛顿大学。该光谱仪允许在各种领域进行研究，例如加速具有重要经济意义的化学反应的领域，并允许研究生物学相关物种。通常，NMR光谱是化学家可用的最强大工具之一，用于阐明分子结构。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液中分子或固态中分子之间相互作用的动力学。对于正在进行边境研究的化学家来说，获得最先进的NMR光谱仪至关重要。该工具是该机构的化学和生物化学本科生和研究生的教学和研究培训的组成部分，以及乔治敦大学和美国海军学院等附近的大学。该乐器还用于大学NMR暑期学校，并与博物馆合作研究文化遗产材料。NMR光谱仪的奖励旨在增强各级研究和教育。它特别影响基于主要组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，并分析共轭聚合物混合物和表面含量的聚合物。此外，它还提供了探索可生物降解的聚合物官能化纳米纤维素复合材料和研究文化遗产材料的信息。光谱仪还用于鉴定与农业和食品安全有关的磷（III） - 氧良好。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估来通过评估来支持的。
