MRI: Acquisition of a Scanning Electron Microscope

1039707本主要研究仪器（MRI）计划资助购置一台环境扫描电子显微镜（ESEM），该显微镜配备可变压力样品池，可以对未涂层和水合样品进行成像。ESEM还将配备一个能量色散x射线光谱仪（EDS），可以进行半定量的微化学分析。ESEM将补充史密斯学院显微镜和成像中心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：低品位变质岩中卟啉母岩的地球化学研究；硼掺杂碳纳米管和纤维的化学和结构表征碳酸盐岩成岩作用研究；生物膜的调查;小型哺乳动物脊椎动物分类与功能形态学；热液矿床成因研究；海洋微化石古生物学；以及文物保护的材料研究。史密斯学院是国家？史密斯是美国最大的女子文理学院，超过30%的史密斯女学生主修理科。史密斯在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方面也有良好的记录

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.***
