MRI: Acquisition of a FE-SEM to Enhance Research and Student Training in Biology, Chemistry, Geosciences, Physics, and Engineering at San Francisco State University

化学和生物化学系在旧金山弗朗西斯科州立大学将获得一个高分辨率扫描电子显微镜（HR-SEM）与此奖项从主要研究仪器（MRI）计划。 不同的研究领域形成了这项建议的科学主旨。 化学/生物化学系的主题包括：（a）碱金属掺杂硅沸石膜内电荷传输的基础研究;（B）无机环境污染物（As，Cr，Pb，Se和Zn）与金属和金属氧化物表面的反应。在生物学系，SEM成像将用于研究鸡胚胎早期骨骼肌（肌节）的组织形态发生和分子信号。 在地球科学系，扫描电镜将促进矿物生长结构，矿物成分变化和夹杂物的识别，以估计压力和生长/反应温度的研究，以及锆石生长分区的离子微探针UPb测年。在工程学院，SEM是研究纳米纤维和智能纳米材料表征的不可或缺的工具，并应用于微/纳机电系统（M/NEMS）。扫描电子显微镜是一种强大的工具，可用于成像各种材料，包括生物标本（细菌细胞，细胞器，植物纤维和组织），无机固体（晶体，矿物和岩石），以及一系列现代合成和工业衍生材料（纳米结构材料，表面，薄膜和电路）。 该仪器提供这些材料的拓扑和组成信息。 它是研究此类材料的性质和行为的重要分析工具。 该仪器将由BS和MS学生在他们的研究和实验室培训中使用，为他们在科学和工程领域的职业生涯做好准备。

The Department of Chemistry and Biochemistry at the San Francisco State University will acquire a high resolution scanning electron microscope (HR-SEM) with this award from the Major Research Instrumentation (MRI) program. Diverse research areas form the scientific thrust of this proposal. Topics in the Chemistry/Biochemistry department include (a) fundamental studies of charge transport within alkali metal-doped silica zeolite films; (b) the reactions of inorganic environmental pollutants (As, Cr, Pb, Se, and Zn) with metal and metal oxide surfaces. In the Biology department, SEM imaging will be used to study tissue morphogenesis and molecular signaling for early skeletal muscles (myotome) in chicken embryos. In the Geosciences department, SEM will facilitate the study of mineral growth textures, compositional variations in minerals and identification of inclusions to estimate pressures and temperatures of growth/reaction, and zircon growth zoning for UPb dating on an ion microprobe. In the School of Engineering, SEM is an indispensable tool in the research on nanofabrication and characterization of smart nanomaterials with applications in micro/nanoelectromechanical systems (M/NEMS). A scanning electron microscope is a powerful tool for imaging a wide range of materials including biological specimens (bacterial cells, organelles, plant fibers and tissues), inorganic solids (crystals, minerals, and rocks), and a range of modern synthetic and industrially-derived materials (nano-structured materials, surfaces, thin films, and circuitry). The instrument provides topological and compositional information of these materials. It is an essential analytical tool in research of the properties and behavior of such materials. This instrument will be used by BS and MS students in their research and in laboratory training preparing them for careers in science and engineering with state of the art technology.
