Florida International University will acquire a Scanning Electron Microscope and accessory detectors for research and undergraduate education in Geosciences, Forensic Chemistry and Science Education. Geoscience research projects include study of volcanic processes and the identification of the origin of volcanic ash layers and other volcanic particles in nearby marine sediments, microfossils as preservers of paleoclimate indicators, and geochemistry of minerals in Andean ore deposits for identifying the source of metals in anthropological artifacts. The proposed instrument will be used for a wide range of research applications in Forensic Chemistry through analysis of materials such as gunshot residue, glass, adhesive tape, soil, and ink. The instrument will continue a long-standing partnership between geoscience and chemistry in sharing analytical instruments and it will accommodate remote users in an NSF project to explore the impact of remote instrument operation on undergraduate teaching and learning.This project will enable Florida International University to acquire an SEM (Scanning Electron Microscope) with EDS (energy dispersive X-ray), XRF (X-Ray Fluorescence) and CL (Cathodoluminescence) capabilities. The proposed instrument will support Geoscience research in the areas of volcanology and igneous geochemistry, paleontology and stratigraphy, and ore geochemistry and geoarchaeology, and Forensic Chemistry research on a wide array of forensic materials (glass, paint, textiles). The common theme of this research is the application of microbeam instruments with diverse capabilities for investigation of the concentrations and spatial distribution of major and trace elements in geologic and forensic materials. Advancement of knowledge in these fields will be supported by shared expertise and the versatile capabilities of the SEM acquisition together with other available instrumentation. Knowledge will also be advanced in the understanding of student learning, especially the impact of using major instrumentation made possible through remote operation.

佛罗里达国际大学将获得一台扫描电子显微镜和辅助探测器，用于地球科学、法医化学和科学教育的研究和本科教育。地球科学研究项目包括研究火山过程，查明火山灰层和附近海洋沉积物中其他火山颗粒的来源，作为古气候指标的微化石，以及安第斯矿床中矿物的地球化学，以查明人类学人工制品中金属的来源。拟议的仪器将用于法医化学的广泛研究应用，通过分析材料，如枪击残留物，玻璃，胶带，土壤和墨水。该仪器将继续地球科学和化学之间在共享分析仪器方面的长期伙伴关系，并将在NSF项目中为远程用户提供服务，以探索远程仪器操作对本科教学的影响。该项目将使佛罗里达国际大学能够获得一台SEM具有EDS（能量色散X射线）、XRF（X射线荧光）和CL（阴极发光）功能的扫描电子显微镜。拟议的仪器将支持火山学和火成岩地球化学、古生物学和地层学、矿石地球化学和地质考古学等领域的地球科学研究，以及对各种法医材料（玻璃、油漆、纺织品）的法医化学研究。本研究的共同主题是应用具有不同能力的微束仪器来调查地质和法医材料中主要和微量元素的浓度和空间分布。这些领域的知识进步将得到共享的专业知识和SEM收购的多功能以及其他可用仪器的支持。知识也将在学生学习的理解，特别是使用主要仪器的影响，通过远程操作成为可能。
