Funds obtained from this proposal will be used to acquire a 400 MHz NMR spectrometer equipped with the necessary accessories for conducting state-of-the-art solid state NMR materials characterization experiments. The accessories will include a double-resonance, magic angle spinning (MAS) probe, which is essential for many solid state NMR spectroscopic applications, as well as a single-resonance CRAMPS (Combined Rotation and Multiple Pulse Sequence) probe for solid state NMR spectroscopy of the 1H nucleus. This requested instrumentation will provide greatly improved solid state NMR spectroscopic capabilities for studying a wide range samples, hence advancing the interdisciplinary materials research being conducted in a broad range of departments at Northwestern University (NU). Research programs which would immediately benefit from incisive condensed matter NMR characterization capabilities include those studying novel transition metal reagents for organic synthesis, novel opto-electronically active solids for optical communications, data storage, and organic transistors, metal-organic frameworks for efficient energy storage and catalysis, silicon-based cage structures and nanocapsules having unusual architectures, graphene nanoplatelets and carbon nanorods for solid state electronics and high-strength materials, novel structural and barrier polymers, and solid state natural materials such as resins and gums from plant exudates. The more sensitive one- and two-dimensional solid state NMR spectroscopy at ambient and variable temperatures offered by this new instrument will significantly enable far more definitive structural characterization of these materials, leading to a more detailed understanding of their functionality. The ability to conduct these studies in-house with high throughput and rapid feedback will not only allow NU materials research to move forward more expeditiously, but will also provide a more complete educational experience for graduate students who will learn modern solid state NMR spectroscopic techniques in a hands-on manner while applying it to their own research. Additionally, advanced undergraduate courses in the Chemistry, Chemical Engineering, and Materials Science and Engineering programs at NU will introduce experiments with this instrumentation. These educational benefits will spread far beyond NU as graduate and undergraduate students move on to other positions.Modern Nuclear Magnetic Resonance (NMR) spectroscopy is an extremely powerful technique for understanding the structure and function of solid materials. Funds from this proposal will be used to acquire a state-of-the-art spectrometer for use by a broad community of materials research scientists and their students at Northwestern University. Interdisciplinary research being conducted in many departments will benefit from the structural characterization capabilities offered by the proposed instrument and not currently available to us. The data from this instrument will lead to a better understanding of a wide range of solid state materials currently under study and which are important to the development of more selective, efficient, and environmentally friendly catalytic processes, new materials for energy storage, opto-electronic materials for high-speed communications, data storage, and printed transistors, and stronger, lighter weight structural materials. This requested instrument will also play a major role in educational programs for our graduate and undergraduate students.

从这一提案中获得的资金将用于购置一台400兆赫核磁共振波谱仪，配备必要的附件，用于进行最先进的固态核磁共振材料特性鉴定实验。 附件将包括一个双共振魔角旋转（MAS）探头，这是许多固态NMR光谱应用所必需的，以及一个单共振CRAMPS（组合旋转和多脉冲序列）探头，用于1H核的固态NMR光谱。 这种要求的仪器将提供大大改善的固态NMR光谱能力，用于研究广泛的样品，从而推进西北大学（NU）广泛的部门正在进行的跨学科材料研究。 将立即受益于敏锐的凝聚态NMR表征能力的研究计划包括研究用于有机合成的新型过渡金属试剂，用于光通信、数据存储和有机晶体管的新型光电活性固体，用于有效能量存储和催化的金属有机框架，具有不寻常结构的硅基笼状结构和纳米胶囊，用于固态电子和高强度材料的石墨烯纳米片和碳纳米棒、新型结构和阻隔聚合物以及固态天然材料如来自植物分泌物的树脂和树胶。 这种新仪器在环境温度和可变温度下提供的更灵敏的一维和二维固态NMR光谱将显着实现这些材料的更明确的结构表征，从而更详细地了解其功能。 在内部进行这些研究的能力具有高通量和快速反馈，不仅可以使NU材料研究更快地向前推进， 还将提供一个更完整的教育经验，研究生谁将学习现代固态核磁共振光谱技术在实践的方式，同时将其应用到自己的研究。 此外，NU的化学，化学工程和材料科学与工程课程的高级本科课程将介绍这种仪器的实验。 随着研究生和本科生转向其他职位，这些教育优势将远远超出NU。现代核磁共振（NMR）光谱是了解固体材料结构和功能的一种非常强大的技术。该提案的资金将用于购买最先进的光谱仪，供西北大学的材料研究科学家及其学生广泛使用。 在许多部门正在进行的跨学科研究将受益于拟议的仪器提供的结构表征能力，目前还没有提供给我们。 该仪器的数据将有助于更好地了解目前正在研究的各种固态材料，这些材料对于开发更具选择性，高效和环保的催化过程，新的储能材料，用于高速通信的光电材料，数据存储和印刷晶体管以及更强，更轻的结构材料非常重要。 这一要求的工具也将在我们的研究生和本科生的教育计划中发挥重要作用。
