A grant was awarded to Chicago State Univeristy to acquire a scanning electron microsope (SEM). This instrument will enhance the resources of the core electron microscopy facility. The newly installed SEM will yield excellent secondary electron images in standard high vacuum mode and provide the capability to image uncoated and partially hydrated samples in the low vacuum mode using the backscatter detectors. Moreover it will allow easy collection of high-resolution digital images for presentation and publication. The WEB-SEM option that will allow us to actively use the microscope from a remote location, like an elementary school classroom, to support our outreach efforts. Research projects include developing zinc oxide films for solar cells; monitoring the products and processes of microwave enhanced chemistry; developing self-healing bone cement; and understanding the biochemistry of the assembly of the microtubule associated protein Tau; understanding the changes in starch granule breakdown in alfalfa; exploring the differentiation and apoptosis of cells in the colon and ileum after thermal injury; and understanding the role of truncated actin binding proteins in altering the dynamics and structure of the cytoskeleton.The SEM will be used to support the educational and outreach goals of the university. The equipment will be used extensively in the Techniques in Electron Microscopy course and less extensively to support introductory courses for biology and science education majors. Two summer enrichment courses for minority students use the SEM for workshops and to support independent research projects. Taken together, these two programs address the needs of high school and early college students in developing their STEM skills. The WEB-SEM module will allow us to develop an outreach program where 6-12 teachers in the Chicago Public Schools can use the microscope from a remote location to support their classroom curriculum. Given Chicago State's predominantly minority student population and the demographics of the surrounding community, we strongly feel that we are in the position to effectively use the requested equipment to bolster both research and science education among underrepresented groups.

芝加哥州立大学获得了一笔赠款，用于购买扫描电子显微镜。 该仪器将增加核心电子显微镜设施的资源。新安装的扫描电镜将在标准高真空模式下产生出色的二次电子图像，并提供在低真空模式下使用反向散射探测器对未涂覆和部分水合样品进行成像的能力。此外，它还可以方便地收集高分辨率的数字图像，用于演示和出版。WEB-SEM选项将允许我们从远程位置（如小学教室）积极使用显微镜，以支持我们的推广工作。研究项目包括开发太阳能电池用氧化锌薄膜;监测微波增强化学的产品和过程;开发自愈骨水泥;了解微管相关蛋白Tau组装的生物化学;了解苜蓿淀粉颗粒分解的变化;探索热损伤后结肠和回肠细胞的分化和凋亡;以及了解截短的肌动蛋白结合蛋白在改变细胞骨架的动力学和结构中的作用。SEM将用于支持大学的教育和推广目标。该设备将广泛用于电子显微镜技术课程，并不广泛地支持生物学和科学教育专业的入门课程。为少数民族学生开设的两个暑期强化课程利用SEM举办讲习班，并支持独立的研究项目。总的来说，这两个项目解决了高中和早期大学生在发展STEM技能方面的需求。WEB-SEM模块将允许我们开发一个外展计划，芝加哥公立学校的6-12名教师可以从远程位置使用显微镜来支持他们的课堂课程。鉴于芝加哥州的主要少数民族学生人口和周围社区的人口统计数据，我们强烈认为，我们能够有效地使用所要求的设备，以支持研究和科学教育之间的代表性不足的群体。
