Acquisition of a scanning electron microscope, Beloit College

这项拨款通过主要研究仪器（MRI）计划获得，为贝洛伊特学院的地质学、生物学、化学、人类学和博物馆研究的研究和培训提供了现代全自动低真空扫描电子显微镜和轻元素EDS探测器（SEM-EDS）的部分费用支持。SEM-EDS分析是表征微米尺度表面形貌和化学成分的重要工具。目前学生和教师的研究将通过获得新的SEM-EDS系统得到加强，包括：1)不列颠哥伦比亚省海岸山脉的变质岩石学和构造研究；2)希腊Syros俯冲带变质作用；3)威斯康星州中南部淡水小溪微生物结核的化学、生物和物理环境；4)智利铜和青铜文物的来源研究；5)威斯康辛州西南部戈特沙尔岩石避难所的石器使用和磨损模式。此外，新的SEM-EDS设备将通过允许Beloit地区的K-12学生对他们收集的标本进行成像和分析，加强Beloit学院的教育推广任务。＊＊＊

0079326DavidsonThis grant, made through the Major Research Instrumentation (MRI) Program, provides partial support of the costs of acquiringa modern, fully automated, low-vacuum scanning electron microscope and light-element EDS detector (SEM-EDS) for research and research training in Geology, Biology, Chemistry, Anthropology, and Museum Studies at Beloit College. SEM-EDS analysis is an essential tool in these fields for characterizing surface topography and chemical composition at the micron scale. Current student and faculty research that will be enhanced by the acquisition of the new SEM-EDS system include 1) metamorphic petrology and tectonic studies of the Coast Mountains in British Columbia; 2) subduction-zone metamorphism in Syros, Greece; 3) the chemical, biologic, and physical environment of microbial nodules from a freshwater creek in southcentral Wisconsin; 4) provenance studies of copper and bronze artifacts from Chile; and 5) use and wear patterns of stone tools from the Gottschall rock shelter in southwestern Wisconsin. In addition, the new SEM-EDS facility will enhance the educational outreach mission at Beloit College by allowing K-12 students in the Beloit area to image and analyze specimens they collect. ***
