RUI: Acquisition of Scanning Electron Microscope

诺克斯学院要求资助一个新的扫描电子 显微镜（SEM），以取代我们的14岁的模型，不 满足教师当前的研究需求，为此， 零件越来越少了L.迪巴斯，首席研究员，将 使用扫描电镜进行她对星虫免疫学的研究， 对星虫体腔细胞结构和功能的研究; 星虫对 高温（热休克）、创伤和再生;以及 在她的研究中进行分类和形态学研究 甲虫M. Brodl在他的研究中， 大麦糊粉层的热激反应，将使用 SEM表征内质网反应 在热休克、恢复和耐热性期间。 响应 在大麦中， 其他植物、无脊椎动物和高等动物的反应。 B。 Kooser将使用扫描电镜在他的自旋标签调查唱 化学改性二氧化硅EPR谱显示 当二氧化硅表面被改性时，性能发生变化。SEM 对蚀变二氧化硅的观察对于确认 表面改性SEM还将成为 电子显微镜的入门项目课程。 一 研究级SEM将允许学生获得出版物- 质量数据，无论是自己还是作为合作伙伴， 研究人员与教师。

Knox College requests funding for a new scanning electron microscope (SEM) to replace our 14-year-old model that does not meet the current research needs of the faculty, and for which parts are getting scarce. L. Dybas, principal investigator, will use the SEM for her studies on sipunculan immunology, focussing on the structure and function of sipunculan coelomocytes; on the responses of sipunculans to elevated temperature (heat shock), wounding and regeneration; and for taxonomic and morphologic studies in her research on ptiliid beetles. M. Brodl, in his studies on the heat shock response in barley aleurone layers, will use the SEM to characterize the response of the endoplasmic reticulum during heat shock, recovery, and thermotolerance. The response in barley is a model system for comparing responses in other plants, invertebrates and higher animals. B. Kooser will use the SEM in his spin label investigations sing chemically modified silica. EPR spectra display behavioral changes as the silica surface is modified. SEM observations of the altered silica are essential to confirm the surface modification. The SEM will also be integral to an introductory project-based course in electron microscopy. A research-level SEM will permit students to obtain publication- quality data either on their own or as co- researchers with faculty.
