MRI: Acquisition of a Dynamic Mechanical AnalyzerNon-technical: This award from the Major Research Instrumentation Program provides Murray State University with a Dynamic Mechanical Analyzer (DMA), thus enhancing a rapidly expanding research and educational initiative in polymer and materials science. The DMA is primarily used to determine the strength and elasticity of polymer films and fibers as well as other plastics and materials. Acquisition of this state-of-the-art instrumentation supports a number of multi-disciplinary and collaborative research and education efforts across the Jesse D. Jones College of Science, Engineering and Technology and expands industrial outreach activities in the region. The instrumentation directly impacts research teams within the college, where an understanding of the fundamental mechanical properties of novel plastics and materials advances applications in energy storage, electronic devices and liquid crystalline technologies. The integration of a practical instrument component and "hands-on" training into lecture and laboratory courses for undergraduate and graduate (Masters) students within the college further improves an already growing curriculum in polymer and materials science. Since Murray State is a comprehensive university in rural, far-western Kentucky, many undergraduates are first-generation college students, thus access to this instrumentation is extremely rare and provides a tremendous advantage in gaining meaningful employment or in acceptance into pre-professional school. Technical: The Department of Chemistry at Murray State University (MSU) will acquire a TA Q800 Dynamic Mechanical Analyzer (DMA), complete with humidifier and low temperature capabilities, for the mechanical testing of polymer films, fibers and liquid crystalline materials. The DMA instrumentation immediately enhances the research programs of the three PIs, all of whom have been very active in the promotion and publication of their research. Since 2010, the PIs have collectively mentored 27 students (20 undergraduate, 7 Masters) and published 14 peer-reviewed papers (12 with student co-authors). Specific projects that benefit from this instrumentation include (a) ionic-liquid containing polyester networks for use in electroactive devices (PI Miller), (b) ionic-liquid containing polyurethanes for microfluidic devices and ion selective electrodes (co-PI Johnson) and (c) liquid crystalline materials (co-PI Allenbaugh). In order to enhance these projects, the standard film/fiber tension kits as well as the humidity and submersion features are used to test the mechanical strength of novel materials developed in the laboratory under a controlled environment, while liquid crystalline materials are tested using the parallel plate and/or shear sandwich accessories. Dissemination of the results from these experiments is made in the form of peer-reviewed publications as well as undergraduate student presentations at local, regional and national conferences. Various lecture and laboratory classes, ranging from Polymer Chemistry and Materials Science to Instrumental Analysis, are also enhanced through the integration of this instrumentation and hands-on training. Beyond teaching and research, the DMA instrumentation allows MSU to establish collaborative efforts with regional companies such as Ashland and Estron Chemical, Inc. that aid in the development of commercial products in applications ranging from paints and coatings to construction materials.

核磁共振成像：获得动态力学分析仪非技术性：这项来自主要研究仪器计划的奖项为默里州立大学提供了动态力学分析仪（DMA），从而加强了聚合物和材料科学领域迅速扩大的研究和教育计划。DMA主要用于测定聚合物薄膜和纤维以及其他塑料和材料的强度和弹性。 这种最先进的仪器的收购支持了整个杰西D多学科和协作研究和教育工作的数量。琼斯科学、工程和技术学院，并扩大该地区的工业推广活动。该仪器直接影响学院内的研究团队，在那里对新型塑料和材料的基本机械性能的理解推进了储能，电子设备和液晶技术的应用。一个实用的仪器组件和“动手”培训到讲座和实验室课程的本科生和研究生（硕士）的学生在学院内的整合，进一步提高了聚合物和材料科学已经不断增长的课程。由于默里州立大学是一所综合性大学，位于偏远的肯塔基州西部农村，许多本科生都是第一代大学生，因此获得这种仪器是非常罕见的，并在获得有意义的就业或接受进入职业预科学校提供了巨大的优势。技术支持：默里州立大学（MSU）化学系将购买一台TA Q800动态力学分析仪（DMA），该分析仪配有加湿器和低温功能，用于聚合物薄膜、纤维和液晶材料的力学测试。 DMA仪器立即增强了三个PI的研究计划，他们都非常积极地推广和出版他们的研究。 自2010年以来，PI已经集体指导了27名学生（20名本科生，7名硕士生），并发表了14篇同行评审论文（12篇与学生合著）。 受益于该仪器的具体项目包括（a）用于电活性装置的含离子液体的聚酯网络（PI米勒），（B）用于微流体装置和离子选择性电极的含离子液体的聚氨酯（co-PI约翰逊）和（c）液晶材料（co-PI艾伦博）。为了加强这些项目，标准的薄膜/纤维张力套件以及湿度和浸没特性用于在受控环境下测试实验室开发的新型材料的机械强度，而液晶材料则使用平行板和/或剪切夹层附件进行测试。从这些实验的结果的传播是在同行评议的出版物，以及本科生在地方，区域和国家会议的演示文稿的形式。 各种讲座和实验室课程，从高分子化学和材料科学到仪器分析，也通过这种仪器和实践培训的整合得到增强。除了教学和研究，DMA仪器允许密歇根州立大学建立与区域公司，如阿什兰和埃斯特朗化学公司的合作努力。这有助于开发从油漆和涂料到建筑材料等应用中的商业产品。
