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.***

1039707 Bradyththis主要研究仪器（MRI）计划授予的赠款支持配备有可变压力样品细胞的环境扫描电子显微镜（ESEM），该电池可实现未涂层和水合样品的成像。 ESEM还将配备能量分散X射线光谱仪（EDS），该光谱仪将允许半定量的微化学分析。 ESEM将在史密斯学院的显微镜和成像中心（CMI）中补充现有的传输电子显微镜（TEM）和激光扫描共聚焦显微镜（LSCM）。 研究应用程序将包括：低年级变质岩石中牙核细胞的地球化学研究；硼掺杂碳纳米管和纤维的化学和结构的表征；碳酸盐成岩作用；生物膜调查；小型哺乳动物脊椎动物分类学和功能形态；水热矿石沉积的岩发生研究；海洋微化石古生物学；以及历史保存艺术的材料研究。 史密斯学院是该国最大的女性文科学院，而史密斯女性则是一门科学专业的30％。 史密斯还拥有招募人数不足的学生，来自低收入家庭的学生和第一代大学生的记录。***
