This Major Research Instrumentation (MRI) grant provides funding to allows Saginaw Valley State University (SVSU) to replace an existing 25-year-old transmission electron microscope (TEM) with a new JEOL JEM-1230 TEM, acquire sample preparation equipment for the characterization of materials, and add an Oxford Instruments INCA 250 energy dispersive spectrometer (EDS) to the current scanning electron microscope. The new TEM provides high resolution morphological imaging of biological and material samples as well as electron diffraction of materials using 120 kV accelerating voltage. The EDS system supplies elemental analysis, image capture, and phase mapping of materials.The electron microscopy facility at SVSU has and continues to have a broad impact on education, research, and community outreach. While the biology department maintains the facility, faculty and students from biology, chemistry, mechanical engineering, and electrical engineering use it. Faculty and students at SVSU conduct a wide variety of research, a few examples are: immunogold imaging, examination of animal organs, plant cells, DNA, biomaterials, ceramics, nanoparticles, and metals. Through the equipment acquisitions under this project, a greater number of undergraduate students and faculty at SVSU will be able to engage in electron microscopy course work and research. Also, outreach activities for middle, high school, and community college students from the surrounding rural and urban areas will continue to grow and expose these constituents to advanced research and analysis techniques in science and engineering. These programs will continue to have a significant impact in attracting women and minorities to careers in science, engineer, and technology. Additionally, local small and medium sized businesses will use the facility to conduct basic research on new products and evaluate manufacturing processes.

这项主要研究仪器（MRI）拨款提供资金，允许萨吉诺谷州立大学（SVSU）用新的JEOL JEM-1230透射电子显微镜取代现有已有25年历史的透射电子显微镜（TEM），获得用于表征材料的样品制备设备，并在当前的扫描电子显微镜上增加一台牛津仪器INCA 250能量色散光谱仪（EDS）。新的TEM提供了生物和材料样品的高分辨率形态成像以及材料的电子衍射，使用120kv加速电压。EDS系统提供元素分析、图像捕获和材料的相位映射。SVSU的电子显微镜设备已经并将继续对教育，研究和社区外展产生广泛的影响。而生物系维护设施，教师和学生从生物，化学，机械工程和电气工程使用它。SVSU的教师和学生进行各种各样的研究，其中一些例子是：免疫金成像，动物器官，植物细胞，DNA，生物材料，陶瓷，纳米粒子和金属的检查。通过该项目下的设备采购，SVSU更多的本科生和教师将能够从事电子显微镜课程工作和研究。此外，面向周边农村和城市地区的初高中和社区大学学生的拓展活动将继续增加，并使这些学生接触到科学和工程领域的先进研究和分析技术。这些项目将继续对吸引妇女和少数民族从事科学、工程和技术事业产生重大影响。此外，当地中小企业将利用该设施进行新产品的基础研究和生产过程评价。
