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

0111471哈格曼这一赠款，通过主要研究仪器计划，支持收购环境扫描电子显微镜（FEI-菲利普斯XL 30 ESEM-TMP）和能量色散光谱仪（EDAX CDU-UT），将被安置在艺术与科学学院的电子显微镜实验室在阿巴拉契亚州立大学。该仪器将显着改善和扩大教师和本科生在阿巴拉契亚州地球科学，在学院的其他部门和区域社区的研究机会。新的ESEM将提供以下新功能，这些功能是我们16年前的传统Hitachi S570 SEM目前无法提供的。(1)未涂覆样品的成像;（2）元素分析和数字载物台绘图;（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放大率;（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）窗口驱动操作，便于不同用户群体访问。ESEM将支持地质系的五名主要研究人员，他们以前曾获得NSF的支持。该提案支持的初步项目包括：（1）苔藓虫群体生长习性：形态生态空间的宏观进化模式（S. J. Hageman）;（2）超高压和高温变质岩石（R.N. Abbott）;（3）气候变化与冰海沉积物来源（E.A.科万）;（4）北美东部白垩纪苔藓虫（F.K. McKinney）;（5）碳酸盐泥丘中的水泥地层学（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师、研究生和本科生的研究和课程工作。这一工具将为社区外联提供一个极好的重点，因为其产品是视觉的、有形的，并来自最先进的技术。***

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. ***
