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。这笔赠款的资金将用于支持波特兰州立大学（PSU）购买一台配备可变压力单元的扫描电子显微镜（VP-SEM），用于地球科学研究和教育。 该仪器将立即影响四名教师PI及其学生的研究计划，以调查环境矿物学的学科，包括热液微生物矿化过程，火成岩学和材料研究。 VP-SEM将通过其并入PSU电子显微镜和纳米技术中心（CEMN），满足校园范围内对生物和非生物材料的高分辨率显微镜的需求。 CEMN目前拥有配套的显微镜仪器，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，将收购的VP-SEM填补了PSU教师和学生可用的显微镜工具套件中的一个重要分析利基。 PSU以其强大的本科生培训计划而闻名。 显微镜非常适合学生参与。 此次收购对学生的影响可能很大，许多接受过最先进显微技术培训的学生在需要高分辨率材料表征的广泛行业中获得就业机会（例如，磁介质、半导体等）。*

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.).***
