This MRI grant provides support for the acquisition of a high resolution Transmission Electron Microscope (TEM) for the Miami University Electron Microscopy Facility (EMF). The EMF is a university wide facility that is utilized extensively in teaching and research. A large number of researchers in many disciplines focus their studies on earth materials, ceramics, semiconductors, catalysts, and biological materials, and therefore TEM is an essential tool to high productivity. This new instrument will become the primary TEM for the characterization of earth materials and chemical/biological compounds. In the past 5 years, the EMF has supported funded research from 56 laboratories in 8 departments of Miami University and other regional institutions, resulting more than 126 publications. A large percent of this usage is with our severely outdated TEM. The new instrument will provide essential capabilities and will be the primary focus of multiple research programs within the campus. The improved resolution and contrast, and the new energy filtering, analytical capabilities and electron diffraction will significantly increase the types of samples that can be analyzed and the types of information obtainable. An enhanced EMF also provides many educational opportunities. The new instrument will be used to train students at all levels. About 30 students and post-docs use TEM. Most faculty have undergraduate students working in their labs. This instrument will be incorporated into the existing courses and will be used to develop new ones. The broader impact will be maximized by using Internet Tele-microscopy. Existing collaborations with other universities and industries will be strengthened and new ones will be established.

这项MRI拨款为迈阿密大学电子显微镜设施（EMF）购置高分辨率透射电子显微镜（TEM）提供支持。电磁场是一所大学广泛使用的设施，广泛用于教学和研究。地球材料、陶瓷、半导体、催化剂、生物材料等领域的研究成为众多学科的研究热点，因此瞬变电磁法是提高生产效率的重要工具。这种新仪器将成为表征土材料和化学/生物化合物的主要TEM。在过去的5年里，EMF资助了迈阿密大学8个系和其他区域机构的56个实验室的研究，发表了126多篇论文。很大一部分使用的是我们严重过时的TEM。新仪器将提供必要的功能，并将成为校园内多个研究项目的主要焦点。提高的分辨率和对比度，以及新的能量滤波、分析能力和电子衍射将显著增加可分析的样品类型和可获得的信息类型。增强的EMF还提供了许多教育机会。新仪器将用于培训各级学生。大约有30名学生和博士后使用TEM。大多数教员都有本科生在他们的实验室工作。这一文书将被纳入现有的课程，并将用于编制新的课程。通过使用互联网远程显微镜，更广泛的影响将得到最大化。将加强与其他大学和行业的现有合作，并建立新的合作关系。
