Technical abstract The scanning electron microscope (SEM) will be used in a variety of research projects spanning physics, chemistry, geology, and biology. Use of this instrument will enable our faculty, students, and external collaborators to obtain new insights in our respective areas of investigation; to image materials over length scales that we are currently unable to study; to train our undergraduate students in an essential material characterization tool; and to fill a critical niche in our equipment base. In particular, the SEM will be used at Coe College to look at laser damage, corrosion, and abrasion of glassy materials; at biocements; and at the mineral deposits of bacteria. Cornell College collaborators will use the instrument to look at zircon grains in geological research, as well as morphological differences in flies in biological work. Every year, the SEM will be used by 5 research groups at Coe College (~6 faculty with 30 Coe students), 7 REU site participants, and as many as 4 Cornell College faculty working with their undergraduates. The SEM will also impact student through its use in courses ranging from Materials Physics and Chemistry, Optics, and Microbiology at Coe to Mineralogy and Petrology from Cornell.General abstract Looking at the world of the very small had become an essential element of doing research with materials of every sort. The Scanning Electron Microscope at Coe College will allow our scientists to look at laser "burn marks" smaller than a human hair and to see cracked glass surfaces that look like a dried desert landscape. These images will advance our understanding of materials that could, someday, be used to store computer memories, to develop better adhesives, to improve commercial glasses, or to understand bacteria that help clean natural environments. Our microscope will also permit us to see if samples differ in their chemical make-up, even if the changes are over tiny areas and distances. But most importantly, this microscope will help in an invaluable goal: to train our college students to become the future leaders in fields of science and technology essential to the welfare of the nation.

技术摘要扫描电子显微镜（SEM）将用于涵盖物理，化学，地质学和生物学的各种研究项目。 使用该工具将使我们的教职员工，学生和外部合作者能够在我们各自的调查领域获得新的见解；在我们目前无法研究的材料上图像材料；用基本的材料表征培训我们的本科生；并在我们的设备基础上填充关键的利基市场。 特别是，将在COE学院使用SEM来研究激光损伤，腐蚀和玻璃材料的磨损；在生物工场上；并在细菌的矿藏中。 康奈尔大学合作者将使用该工具来研究地质研究中的锆石晶粒，以及生物学工作中苍蝇的形态学差异。 每年，COE学院的5个研究小组（约6位有30名COE学生），7名REU网站参与者以及多达4个康奈尔大学教职员工与本科生一起工作。 SEM还将通过其在COE材料物理学和化学，光学和微生物学到矿物学和岩石学的材料物理和化学，光学和微生物学等课程中的使用。 COE学院的扫描电子显微镜将使我们的科学家可以看一下比人头发小的激光“燃烧痕迹”，并看到破裂的玻璃表面看起来像是干燥的沙漠景观。 这些图像将提高我们对有一天可以用来存储计算机记忆，开发更好粘合剂，改善商业眼镜或了解有助于清洁自然环境的细菌的材料的理解。 我们的显微镜还将使我们能够查看样品在化学构成方面是否有所不同，即使变化在很小的区域和距离上也是如此。 但最重要的是，这个显微镜将有助于一个宝贵的目标：培训我们的大学生成为国家福利必不可少的科学技术领域的未来领导者。
