MRI: Acquisition of a Dynamic Mechanical Analyzer

MRI：获得动态机械分析仪非技术性：这项来自重大研究仪器计划的奖项为默里州立大学提供了一台动态机械分析仪(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活动。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。收购这一最先进的仪器支持杰西·D·琼斯科学、工程和技术学院的许多多学科和合作研究和教育工作，并扩大了该地区的工业外展活动。该仪器直接影响到学院内的研究团队，在那里，对新型塑料和材料的基本机械性能的了解促进了能量存储、电子设备和液晶技术的应用。在学院内为本科生和研究生(硕士)开设的讲座和实验室课程中，将实用仪器组件和“动手”培训相结合，进一步完善了聚合物和材料科学方面已经在不断增长的课程。由于默里州立大学是肯塔基州偏远西部农村的一所综合性大学，许多本科生都是第一代大学生，因此使用这种工具极其罕见，在获得有意义的工作或进入职业预科学校方面提供了巨大的优势。技术：默里州立大学(MSU)化学系将购买一台TA Q800动态机械分析仪(DMA)，配备加湿器和低温功能，用于聚合物薄膜、纤维和液晶材料的机械测试。DMA工具立即加强了三个私人投资机构的研究方案，所有这些机构都非常积极地促进和发表其研究成果。自2010年以来，PIs共指导了27名学生(20名本科生，7名硕士)，发表了14篇同行评议论文(12篇与学生共同撰写)。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 Miller)，(B)用于微流控装置和离子选择电极的含离子液体的聚氨酯(co-Pi Johnson)和(C)液晶材料(co-Pi Allenbaugh)。为了加强这些项目，标准的薄膜/纤维拉伸套件以及湿度和浸没特性被用来在受控环境下测试实验室开发的新材料的机械强度，而液晶材料则使用平行板和/或剪切夹层附件进行测试。这些实验的结果以同行评议的出版物以及在地方、区域和国家会议上的本科生陈述的形式进行传播。各种讲座和实验室课程，从聚合物化学和材料科学到仪器分析，也通过将这种仪器和实践培训相结合而得到加强。除了教学和研究，DMA仪器还允许密歇根州立大学与阿什兰和埃斯特龙化学公司等地区性公司建立合作关系，帮助开发从油漆和涂料到建筑材料等应用领域的商业产品。

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.
