MRI-R2: Acquisition of a Field Emission SEM for a Multi-User EM Facility

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。来自NSF MRI-R2计划的资金已授予圣地亚哥州立大学，用于购买配备可变压力能力的场发射扫描电子显微镜（FESEM），数字图像捕获和3D测量软件，X射线微量分析检测器和软件，反向散射检测器，增强型可变压力二次电子检测器和阴极发光检测器，以及用于SEM样品制备的高分辨率溅射镀膜机。FESEM被安置在SDSU生物系的电子显微镜设施中。FESEM可以进行形态学和化学研究，包括：单细胞光合细胞的描述;蛛形纲动物系统学;地质年代学和起源研究;碳纳米管复合材料和显微烧结;以及粉末技术。因此，FESEM收集的数据为生物学，工程和地质科学的各个领域提供了新的见解，并将我们的能力扩展到新的研究和教学领域。SDSU的学生群体在种族上高度多样化。许多学生在SDSU EM设施获得高科技仪器的经验。即将到来的学生和专业参观设施，看看仪器的操作。上师班将此设备纳入学生实验室练习;本科生和研究生操作设备，并参与研究项目。学生研究人员成为共同作者，在同行评议的期刊上发表，并在地方和国家科学会议上展示他们的成果。新的FESEM还用于区域外展项目，可以将现场SEM图像发送给20英里外的加利福尼亚州丘拉维斯塔的Clear View小学的下一代科学家。 更多详细信息请访问http://www.sci.sdsu.edu/emfacility。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Funds from the NSF MRI-R2 program have been award to San Diego State University for the purchase of a Field Emission Scanning Electron Microscope (FESEM) equipped with variable pressure capability, digital image capture and 3D measurement software, X-ray microanalysis detector and software, backscatter detector, enhanced variable pressure secondary electron detector, and cathodoluminescence detector, as well as a high resolution sputter coater for SEM sample preparation. The FESEM is housed in the Electron Microscope Facility in the Department of Biology at SDSU. The FESEM enables morphological and chemical studies including: description of unicellular photosynthetic cells; arachnid systematics; geochronology and provenance studies; carbon nanotube composites and microsintering; and powder technology. The data collected with the FESEM therefore provides new insights into diverse fields of biology, engineering, and geological sciences and expands our capabilities into new areas of research and teaching. The student body at SDSU is highly diverse ethnically. Many students gain experience with high technology instrumentation at the SDSU EM Facility. Incoming students and majors tour the Facility to see the instrumentation in operation. Upper division classes incorporate this equipment into student laboratory exercises; undergraduate and graduate students operate the equipment and are involved in research projects. Student-researchers become co-authors, publish in peer-reviewed journals, and present their results at local and national scientific meetings. The new FESEM is also used in regional outreach projects and can send live SEM images to the next generation of scientists at Clear View Elementary School, 20 miles away in Chula Vista, CA.
