This grant provides support for the acquisition of a nuclear magnetic resonance (NMR) spectrometer for materials research and education in the Departments of Chemistry, Ceramic Engineering, Chemical Engineering, and Graduate Center for Materials Research at the University of Missouri-Rolla. This NMR system will be used in research and analysis of solid materials, and to train students across disciplines on the use of NMR for the characterization of materials. This equipment will provide considerable new capabilities and allow important new experiments to be conducted. It will provide capabilities for cross-polarization (CP) and magic-angle spinning (MAS) and extended temperature capability, to allow researchers to probe the dynamics of polymers, phosphate glasses, hybrid and nano-filled composites. A high temperature, wide-line deuterium probe will allow the extension of current work on interfacial polymers to explore their behavior at higher temperatures, well above current temperature limits. Advances in materials science and engineering will take place because of our better understanding of the structure and behavior of solid-state materials. Next generation materials will need to be understood at the molecular level if we are to exploit their potential properties. Polymer thin films, inorganic glasses and other materials are difficult to characterize with many techniques. NMR studies provide a distinct view of the structure and dynamics of these systems that is unavailable from other methods. The research discoveries supported by this instrumentation will be of considerable importance in our understanding of novel materials, helping to keep the U.S. at the forefront of materials research. This will be done through the resulting research being disseminated in journals, at scientific meetings, and on the world-wide web. The impact of the work will be in areas where thin films and glass materials are used, such as in electronics, composites, adhesives, sealants and coatings. The students trained on this instrumentation will be from a wide variety of backgrounds and their exposure to this powerful technique, and the breadth of problems that it can help solve, will broaden their horizons considerably.

该补助金为密苏里大学罗拉分校化学，陶瓷工程，化学工程和材料研究生中心的材料研究和教育部门购买核磁共振（NMR）光谱仪提供支持。该NMR系统将用于固体材料的研究和分析，并培训跨学科的学生使用NMR进行材料表征。该设备将提供相当大的新能力，并允许进行重要的新实验。它将提供交叉极化（CP）和魔角旋转（MAS）的能力以及扩展的温度能力，使研究人员能够探测聚合物，磷酸盐玻璃，混合和纳米填充复合材料的动力学。一个高温，宽线氘探针将允许扩展目前的工作界面聚合物，以探索他们的行为在更高的温度下，远高于目前的温度限制。材料科学和工程的进步将因为我们对固态材料的结构和行为的更好理解而发生。如果我们要开发下一代材料的潜在特性，就需要在分子水平上理解它们。聚合物薄膜、无机玻璃和其他材料的特性难以用许多技术来表征。核磁共振研究提供了一个独特的观点，这些系统的结构和动力学，是从其他方法无法获得。该仪器支持的研究发现将对我们理解新材料具有相当重要的意义，有助于保持美国在材料研究方面的领先地位。这将通过在期刊、科学会议和万维网上传播研究成果来实现。这项工作的影响将在薄膜和玻璃材料的使用领域，如电子，复合材料，粘合剂，密封剂和涂料。在这种仪器上接受培训的学生将来自各种各样的背景，他们接触到这种强大的技术，以及它可以帮助解决的问题的广度，将大大拓宽他们的视野。
