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.

旧金山州立大学化学与生物化学系将从主要研究仪器（MRI）项目中获得一台高分辨率扫描电子显微镜（HR-SEM）。不同的研究领域构成了该提案的科学主旨。化学/生物化学系的课题包括：(a)碱金属掺杂二氧化硅沸石膜内电荷输运的基础研究；(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。在生物系，扫描电镜成像将用于研究鸡胚胎早期骨骼肌（肌组）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、矿物成分变化和包裹体识别的研究，以估计生长/反应的压力和温度，以及锆石生长分区的UPb定年在离子微探针上。在工程学院，扫描电镜是研究纳米制造和表征智能纳米材料在微/纳米机电系统（M/NEMS）中的应用不可或缺的工具。扫描电子显微镜是成像各种材料的强大工具，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）。该仪器提供了这些材料的拓扑结构和成分信息。它是研究这类材料的性质和行为必不可少的分析工具。该仪器将用于学士和硕士学生的研究和实验室培训，为他们在科学和工程领域的职业生涯与最先进的技术做好准备。
