项目摘要

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.

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 正在购买一台 500 MHz 固态核磁共振 (NMR) 波谱仪。当分子暴露于不同频率的光时，核磁共振波谱仪可测量原子的磁性。这些信号识别化合物中存在的原子。该光谱仪可探测固体材料的特性，包括电池、聚合物、催化剂和生物分子。 NMR 供从事材料、纳米科学、催化和能源科学跨学科研究的化学家、工程师及其学生使用。该仪器是马里兰大学的第一台固态核磁共振仪。它是该地区其他机构可用的资源，也是培训学生 NMR 技术的宝贵工具，为他们以后在学术界或工业界的职业生涯做好准备。这款 NMR 波谱仪可增强各个层面的研究和教育。基础设施的收购影响了葫芦脲的制备、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以及以氧气作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、探测超导固体中的结构以及研究电化学能量存储。
