MRI: Acquisition of a Scanning Electron Microscope

1039707 BradyThis重大研究仪器（MRI）计划赠款支持购买环境扫描电子显微镜（ESEM），该显微镜配备了可变压力样品池，可以对未涂层和水合样品进行成像。 环境扫描电镜还将配备能量色散X射线光谱仪（EDS），可进行半定量微量化学分析。 ESEM将补充史密斯学院显微镜和成像中心（CMI）现有的透射电子显微镜（TEM）和激光扫描共聚焦显微镜（LSCM）。 研究应用将包括：低级变质岩中成斑细胞的地球化学调查;掺硼碳纳米管和纤维的化学和结构表征;碳酸盐成岩作用研究;生物膜调查;小型哺乳动物脊椎动物分类和功能形态学;热液矿床的岩石成因调查;海洋微化石古生物学;和材料研究的历史保护艺术。史密斯学院是国家？史密斯学院是美国最大的女子文理学院，超过30%的史密斯女性主修理科。 史密斯也有招收代表性不足的学生，来自低收入家庭的学生和第一代大学生的良好记录。

1039707BradyThis Major Research Instrumentation (MRI) Program grants supports acquisition of an environmental scanning electron microscope (ESEM) equipped with a variable pressure sample cell that enables imaging of uncoated and hydrated samples. The ESEM will also be equipped with an energy dispersive x-ray spectrometer (EDS) that will permit semi-quantitative microchemical analysis. The ESEM would complement an existing transmission electron microscope (TEM) and laser scanning confocal microscope (LSCM) in the Center for Microscopy and Imaging (CMI) at Smith College. Research applications will include: geochemical investigations of porphyroblasts in low grade metamorphic rocks; characterization of the chemistry and structure of boron doped carbon nanotubes and fibers; studies of carbonate diagenesis; biofilm investigations; small mammalian vertebrate taxonomy and functional morphology; petrogenetic investigations of hydrothermal ore deposits; marine microfossil paleontology; and materials studies for the historic preservation of art. Smith College is the nation?s largest liberal arts college for women and more than 30% of Smith women major in a science. Smith also has a strong record of recruiting underrepresented students, students from low-income families, and first generation college students.***
