Acquisition of a 300MHz Nuclear Magnetic Resonance Solids Instrument

该奖项为300MHz核磁共振（NMR）固体仪器提供部分支持，该仪器将由从事聚合物材料研究的研究人员和学生共享。麻省大学洛厄尔分校先进材料中心（CAM）的教职员工的研究涉及多种新型有机和无机材料的制备和表征。大部分材料需要在固体状态下进行检查和表征，因为它们的独特性质只有在这种物质状态下才能观察到。在不同温度下进行的核磁共振交叉极化/魔角旋转、质子和氘实验获得的宝贵数据将有助于确定固体的详细分子结构和固体的分子运动动力学。关于形貌和结晶度，关于表面和界面的详细信息将很容易获得核磁共振仪器。CAM现有的仪器无法获得这些有价值的知识。作为CAM正在进行的研究的一部分，新的聚合物、复合材料、有机晶体和其他材料不断产生，当前和未来的研究将受益。由美国国家科学基金会和其他联邦机构资助的一些正在进行的项目将是该工具的直接受益者。该提案的资金将为CAM提供用于固体表征的完整的核磁共振仪器，因为CAM已经为溶液表征做好了准备。除了直接受益和发展CAM研究外，拟议的仪器将扩展和进一步发展马萨诸塞大学洛厄尔分校强大的跨学科博士项目。%%%***

The research of the faculty and staff of the Center for Advance Materials (CAM) at the University of Massachusetts Lowell involves preparation and characterization of a large variety of new and novel organic and inorganic materials. A large portion of the materials need to be examined and characterized in the solid state as their unique properties are observable only in this state of matter. Valuable data, obtained from the nmr cross polarization/magic angle spinning, proton and deuterium experiments carried out at variable temperature would help determine the detailed molecular structure of solids and the molecular motional dynamics of solids. Detailed information about the morphology and crystallinity, about surfaces and interfaces will be readily accessible with the acquisition of the NMR instrumentation. Much of this valuable knowledge cannot be obtained with the existing instrumentation at CAM. Current as well as future research will benefit as new polymers, composites, organic crystals and other materials are continually being generated as part of the ongoing research at the CAM. A number of ongoing projects funded by NSF and other federal agencies will be direct beneficiaries of this instrument. The funding of this proposal will provide the CAM with the full complement of NMR instrumentation for solids characterization, as the CAM is already well equipped for solution characterization. In addition to directly benefit and develop the research of CAM, the proposed instrumentation will expand and further develop the strong interdisciplinary doctoral programs at the University of Massachusetts Lowell.%%%***
