RUI: Acquisition Of An Environmental Scanning Electron Microscope (ESEM) And Energy Dispersive Spectrometer (EDS)

0111471 Hagman这笔赠款是通过重大研究仪器计划提供的，用于购买环境扫描电子显微镜(FEI-Phillips XL30 ESEM-TMP)和能量色散光谱仪(EDAX CDU-UT)，安装在阿巴拉契亚州立大学文理学院的电子显微镜实验室。该仪器将显著改善和扩大阿巴拉契亚州立大学地球科学专业的教职员工和本科生、学院其他院系和地区社区的研究机会。新的环境扫描电子显微镜将提供我们已有16年历史的传统日立S570扫描电子显微镜目前无法提供的以下新功能。(1)未涂覆样品的成像；(2)元素分析和数字化阶段的测绘；(3)水合样品的成像；(4)大样品的广角成像；(5)阴极发光下的成像和分析；(6)二次和背散射电子模式的高倍率；(7)用于出版和图像分析的高分辨率数字图像文件的制作、存储和网络分发；(8)窗口驱动的操作，以便于不同的用户群体访问。环境扫描电子显微镜将支持地质部的五名主要研究人员，他们之前曾得到NSF的支持。该建议支持的初步项目包括：(1)苔藓虫群落生长习性：形态生态空间的宏观演化模式(S.J.Hageman)；(2)超高压和高温变质岩(R.N.Abbott)；(3)气候变化和冰海沉积物来源(E.A.Cowan)；(4)北美东部白垩纪苔藓虫(F.K.McKinney)；(5)碳酸盐泥丘的水泥地层(B.C.Schreiber)。该仪器还将用于地质学、生物学、化学、物理学、人类学和刑事司法系的教职员工、研究生和本科生的研究和课程工作。该仪器将为社区宣传提供极佳的焦点，因为其产品是可视的、有形的，并源自最先进的技术。***

0111471HagemanThis grant, made through the Major Research Instrumentation Program, supports the acquisition of an Environmental Scanning Electron Microscope (FEI-Phillips XL30 ESEM-TMP) and Energy Dispersive Spectrometer (EDAX CDU-UT), to be housed in the Electron Microscopy Laboratory of the College of Arts and Sciences at Appalachian State University. This instrument will significantly improve and expand research opportunities for faculty and undergraduate students in Earth Science at Appalachian State, other departments in the College, and the regional community. The new ESEM will provide the following new capabilities not currently available from our 16 year old conventional Hitachi S570 SEM. (1) imaging of uncoated specimens; (2) elemental analysis and mapping with digital stage; (3) imaging of hydrated specimens; (4) wide angle imaging of large specimens; (5) imaging and analysis under cathode luminescence; (6) high magnification in both secondary and backscattered electron modes; (7) production, storage, and network distribution of high resolution digital image files for publication and image analysis; (8) windows driven operation for easy access by a diverse user population. The ESEM will support five primary researchers in the Department of Geology, who have had previous NSF support. Initial projects supported by this proposal include (1) Bryozoan Colonial Growth Habits: Macroevolutionary Patterns in Morpho-ecospace (S.J. Hageman); (2) Ultra High Pressure and Temperature Metamorphic Rocks (R.N. Abbott); (3) Climatic Variation and Source of Glacio-marine Sediments (E.A. Cowan); (4) Eastern North American Cretaceous Bryozoans (F.K. McKinney); and (5) Cement Stratigraphy in Carbonate Mud-mounds (B.C. Schreiber). The instrument will also be used in research and course work by faculty, graduate students and undergraduates in the departments of Geology, Biology, Chemistry, Physics, Anthropology and Criminal Justice. This instrument will provide an excellent focus for community outreach because its products are visual, tangible and derived from state-of-the-art technology. ***
