Acquisition of Nuclear Magnetic Resonance Spectrometer for Materials Research and Education

这笔赠款用于在密苏里大学罗拉分校化学系、陶瓷工程系、化学工程系和材料研究研究生中心购置一台用于材料研究和教学的核磁共振(核磁共振)光谱仪。该核磁共振系统将用于固体材料的研究和分析，并培训跨学科的学生如何使用核磁共振对材料进行表征。这种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)能力以及扩展的温度能力，使研究人员能够探索聚合物、磷酸盐玻璃、混杂和纳米填充复合材料的动力学。高温、宽线氘探测器将允许扩展目前对界面聚合物的研究，以探索它们在更高温度下的行为，远远高于当前的温度限制。由于我们对固态材料的结构和行为有了更好的了解，材料科学和工程的进步将会发生。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加以理解。聚合物薄膜、无机玻璃等材料很难用多种技术进行表征。核磁共振研究提供了这些系统的结构和动力学的独特观点，这是其他方法无法获得的。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所产生的研究来实现。这项工作的影响将在使用薄膜和玻璃材料的领域，如电子、复合材料、粘合剂、密封剂和涂料。接受这种乐器培训的学生将来自不同的背景，他们接触到这种强大的技术，以及它可以帮助解决的广泛问题，将极大地开阔他们的视野。

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.
