MRI: Acquisition of an Analytical, Variable-pressure Scanning Electron Microscope for Geoscience Research and Education at Portland State University

0923450 hugo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。这笔资金将用于波特兰州立大学（PSU）的地学研究和教育，用于购买配备可变压力电池的扫描电子显微镜（VP-SEM）。该仪器将立即影响到四名pi教授及其学生的研究项目，他们的研究跨越了环境矿物学的学科，包括热液微生物成矿作用过程、火成岩岩石学和材料研究。VP-SEM将通过并入PSU电子显微镜和纳米技术中心（CEMN）来满足校园内对生物和非生物材料的高分辨率显微镜的需求。CEMN目前拥有互补的显微镜仪器，包括电子探针，高真空场发射枪源SEM，透射电子显微镜和聚焦离子束铣削，所有这些都由全职技术人员提供支持。因此，获得的VP-SEM填补了PSU教师和学生可用的显微镜工具套件中的重要分析利基。PSU以其强大的本科培训项目而闻名。显微镜学非常适合学生参与。此次收购对学生的影响可能很大，许多接受过最先进显微镜技术培训的学生在需要高分辨率材料表征（例如，磁性介质，半导体等）的广泛行业中获得就业机会。***

0923450HugoThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Funds from this grant will support the acquisition of a variable pressure cell equipped scanning electron microscope (VP-SEM) for geoscience research and education at Portland State University (PSU). The instrument will immediately impact the research programs of four faculty member PIs and their students for investigations spanning the disciplines of environmental mineralogy including hydrothermal microbial mineralization processes, igneous petrology and materials research. The VP-SEM will serve campus wide needs for high resolution microscopy of both biological and non-biological materials through its incorporation into the PSU Center for Electron Microscopy and Nanotechnology (CEMN). CEMN currently houses complementary microscopy instrumentation including an electron microprobe, high vacuum field emission gun source SEM, transmission electron microscopes and focused ion beam milling, all of which are supported by full time technicians. The VP-SEM to be acquired therefore fills an important analytical niche in the suite of microscopy tools available to faculty and students at PSU. PSU is well recognized for its strong undergraduate training programs. Microscopy is well suited to student engagement. The student impact of this acquisition is likely to be high and many students trained in state-of-the-art microscopy techniques gain employment in a wide range of industries requiring high resolution materials characterization (e.g., magnetic media, semiconductors etc.).***
