This award from the Major Research Instrumentation program and the Established Program to Stimulate Competitive Research (EPSCoR) provides Murray State University (MSU) with funds to purchase a rheometer to enhance undergraduate research and education in the Department of Chemistry and in the Institute of Engineering. The instrumentation will be used to study the rheological (stress-deformation) properties of polymers and plastics, polymer solutions, fluids, resins and other soft materials. Research teams in the Department of Chemistry conduct research to gain an understanding of the fundamental rheological properties of charge-containing plastics and materials critical to the advancement of applications in energy storage, electronic devices and 3D printing. The rheometer enhances significantly the instrumentation available for an expanding, multi-disciplinary program in polymer and materials science at MSU. The "hands-on" training that undergraduates will receive will lead to the improvement of up to five lecture and/or laboratory courses across chemistry and engineering. Since many of these students are from the rural counties of far-western Kentucky, northwestern Tennessee and southern Illinois, this cutting-edge experience will not only deepen their understanding of polymer and materials science but also increase the likelihood that these students gain meaningful employment in STEM-related careers in the region and/or better prepare them for pre-professional school. Finally, the rheometer will enhance MSU's ability to partner with regional R&D/manufacturing facilities thereby strengthening existing collaborations and enabling new ones.The acquisition of a new rheometer complete with environmental testing chamber, UV accessory and dielectric capabilities is supported jointly by the Major Research Instrumentation Program and the EPSCoR program. The rheometer will enhance a rapidly growing undergraduate research and educational program in polymer and materials science at Murray State University. It will enable real-time and post-cure rheological analysis of polymers, polymer solutions, fluids, resins and other soft materials. Specific projects that would be enhanced include the elucidation of in situ and post-cure rheological properties of poly(ionic liquid) networks (PILs) prepared by thiol-ene/yne "click" photochemistry, the determination of dielectric properties of these PIL networks (including insights into chain dynamics and ion mobility), exploration of dynamic polymeric systems, and the analysis of resins for 3D printing. For all of these projects, the acquisition of rheological data, in particular those obtained using the UV light guide and dielectric accessories, will provide structure-activity information critical to advancing several on-going and future application interests, including gas/ion separation/absorption membrane technologies, microfluidics, electrospinning and other electroactive devices. The rheometer will also allow for the educational advancement of students in several courses between the Department of Chemistry and the Institute of Engineering: Polymer Chemistry, including the development of a brand new Polymer Chemistry Laboratory course, Instrumental Analysis, Mechanics of Materials and Mechanics of Materials Laboratory. Beyond teaching and research, addition of the rheometer will further facilitate an active collaboration with a regional chemical company in order to improve several current commercial product lines.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项来自主要研究仪器计划和刺激竞争研究既定计划 (EPSCoR)，为默里州立大学 (MSU) 提供资金购买流变仪，以加强化学系和工程学院的本科生研究和教育。该仪器将用于研究聚合物和塑料、聚合物溶液、流体、树脂和其他软材料的流变（应力变形）特性。化学系的研究团队进行研究，以了解对储能、电子设备和 3D 打印应用的进步至关重要的含电荷塑料和材料的基本流变特性。该流变仪显着增强了密歇根州立大学聚合物和材料科学领域不断扩展的多学科项目的可用仪器。本科生将接受的“实践”培训将导致化学和工程领域多达五门讲座和/或实验室课程的改进。由于这些学生中有许多来自肯塔基州西北部、田纳西州西北部和伊利诺伊州南部的农村县，这种前沿的经验不仅会加深他们对聚合物和材料科学的理解，而且会增加这些学生在以下领域获得有意义的就业的可能性：该地区与 STEM 相关的职业和/或更好地为他们进入职业预科学校做好准备。最后，该流变仪将增强密歇根州立大学与区域研发/制造设施合作的能力，从而加强现有合作并实现新的合作。购买配有环境测试室、紫外线配件和介电功能的新型流变仪由主要研究仪器联合支持程序和 EPSCoR 程序。该流变仪将促进默里州立大学聚合物和材料科学领域快速发展的本科生研究和教育项目。它将能够对聚合物、聚合物溶液、流体、树脂和其他软材料进行实时和固化后流变分析。 将加强的具体项目包括阐明通过硫醇-烯/炔“点击”光化学制备的聚（离子液体）网络（PIL）的原位和后固化流变特性，确定这些PIL网络的介电特性（包括对链动力学和离子迁移率的见解）、动态聚合物系统的探索以及用于 3D 打印的树脂分析。对于所有这些项目，流变数据的采集，特别是使用紫外光导和介电配件获得的流变数据，将提供对于推进一些正在进行的和未来的应用兴趣（包括气体/离子分离/吸收）至关重要的结构活性信息膜技术、微流体、静电纺丝和其他电活性装置。 该流变仪还将促进化学系和工程学院之间的几门课程的学生教育进步：高分子化学，包括开发全新的高分子化学实验室课程、仪器分析、材料力学和材料力学实验室。除了教学和研究之外，增加流变仪将进一步促进与地区化学公司的积极合作，以改进当前的几个商业产品线。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值进行评估，被认为值得支持以及更广泛的影响审查标准。
