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.***

1039707Brady这项重大研究仪器 (MRI) 计划资助购买配备可变压力样品池的环境扫描电子显微镜 (ESEM)，可对未涂层和水合样品进行成像。 ESEM 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) 和激光扫描共焦显微镜 (LSCM)。 研究应用将包括：低品位变质岩中成斑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表征；碳酸盐岩成岩作用研究；生物膜调查；小型哺乳动物脊椎动物分类学和功能形态学；热液矿床的岩石成因研究；海洋微化石古生物学；以及艺术历史保护的材料研究。 史密斯学院是全美最大的女子文理学院，超过 30% 的史密斯女生主修科学。 史密斯在招收代表性不足的学生、低收入家庭的学生和第一代大学生方面也有着良好的记录。***
