MRI: Acquisition of an Nuclear Magnetic Resonance (NMR) Spectrometer with Solid-State Capabilities for Shared Use at the University of Maryland

该奖项由主要研究仪器（MRI）和化学研究仪器和设施（CRIF）项目支持。马里兰大学帕克分校的Lyle Isaacs教授及其同事Lawrence Sita、Chunsheng Wang、Dongxia Liu和Efrain Rodriguez正在获得一台500 MHz的固态核磁共振（NMR）光谱仪。当分子暴露在不同频率的光下时，核磁共振光谱仪测量原子的磁性。这些信号可以识别化合物中存在的原子。该光谱仪探测固体材料的性质，包括电池、聚合物、催化剂和生物分子。核磁共振被化学家、工程师和他们的学生用于材料、纳米科学、催化和能源科学的跨学科研究。该仪器是马里兰大学的第一个固态核磁共振仪器。它是该地区其他机构可用的资源，也是培训学生核磁共振技术的宝贵工具，为他们日后在学术界或工业界的职业生涯做好准备。这种核磁共振光谱仪增强了各级的研究和教育。基础设施的获取影响了瓜[n]茎的制备、类金属间簇的研究以及离子载体和水凝胶的自组装。该仪器还用于研究催化金属介导的小分子固定，并以氧为直接氧化剂进行碳氢键活化。该光谱仪可用于从沸石材料制备新型催化剂，探测超导固体结构以及研究电化学储能。

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation and Facilities (CRIF) Programs. Professor Lyle Isaacs from University of Maryland College Park and colleagues Lawrence Sita, Chunsheng Wang, Dongxia Liu and Efrain Rodriguez are acquiring a 500 MHz solid-state nuclear magnetic resonance (NMR) spectrometer. An NMR spectometer measures the magnetic properties of atoms when molecules are exposed to various frequencies of light. These signals identify the atoms present in the compound. This spectrometer probes the properties of solid materials, including batteries, polymers, catalysts and biomolecules. The NMR is used by chemists, engineers and their students working on interdisciplinary research in materials, nanoscience, catalysis and energy science. The instrument is the first solid-state NMR at the University of Maryland. It is a resource available to other institutions in the region and a valuable instrument to train students in NMR techniques preparing them for their later careers in academia or industry. This NMR spectrometer enhances research and education at all levels. The infrastructure acquisition impacts the preparation of cucurbit[n]urils, studies of intermetalloid clusters, and the self-assembly of ionophores and hydrogels. The instrumentation is also used to study catalytic metal-mediated small molecule fixation and to carry out carbon-hydrogen bond activation with oxygen as direct oxidant. The spectrometer is useful for preparing new catalysts from zeolite materials, for probing structures in superconducting solids and for studying electrochemical energy storage.
