An award is made to Lake Superior State University to support the acquisition of a micro X-ray fluorescence spectrometer (μXRF) with remote operation capabilities. The μXRF enables high-resolution imaging and elemental analysis, supports a consortium of 14 researchers at eight institutions and their collaborators, facilitates external use for research, education, engineering/industrial applications, and promotes a regional research community. These capabilities enrich undergraduate education and training across several scientific disciplines, create new opportunities for undergraduate research, and enable the development of new coursework in microanalysis and plant nutrient metabolism. A K-12 outreach program offered in collaboration with the Eastern Upper Peninsula Intermediate School District provides hands-on education opportunities and enhances recruitment of underrepresented students promoting the development of a diverse regional STEM workforce. Work supported by this award will provide practical benefits including improvement in phytoremediation strategies, improved fisheries management practices, and analysis of French colonial artifacts that will be incorporated into public displays at Fort Michilimackinac, part of Mackinac State Historic Parks. Research facilitated by this award will advance our understanding of plant nutrient metabolism, phytoremediation of soils, freshwater ecology, forensic science, organismal biology, geology, and characterization of historical artifacts. The key capabilities of this instrument include elemental quantification and mapping at tens of micrometers resolution under atmospheric pressure, detection limits for heavy elements in the tens of ppm, light element analysis, suitability for analysis of intact and/or living organisms, and high throughput sample analysis. The superior resolution and detection limits compared to XRF and other μXRF instruments will enable element quantification and distribution in a diverse range of organisms. Imaging and quantification of element distributions will enable the investigation of element mobility and storage, enhancing research in plant mineral metabolism and localization of metals in aquatic organisms. This instrument will also allow for the analysis of the rare earth elements in local rock structures for use in rechargeable batteries and of archeological artifacts at Mackinac State Historic Parks.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

苏必利尔湖州立大学获得资助购买具有远程操作功能的微型 X 射线荧光光谱仪 (μXRF)，该 μXRF 能够实现高分辨率成像和元素分析，为由 8 个机构的 14 名研究人员组成的联盟提供支持。他们的合作者，促进研究、教育、工程/工业应用的外部使用，并促进区域研究社区的发展，这些能力可以跨多个丰富的科学学科进行本科教育和培训，为本科生研究创造新的机会，并促进新学科的发展。与东部上半岛中学区合作提供的 K-12 外展计划提供实践教育机会，并加强招收代表性不足的学生，促进多元化区域 STEM 劳动力的发展。该奖项将提供实际效益，包括改进植物修复策略、改进渔业管理实践以及对法国殖民文物的分析，这些文物将纳入麦基诺州立历史研究公园一部分的米奇利麦基诺堡的公共展示中。该奖项的推动将增进我们对植物营养代谢、土壤植物修复、淡水生态学、法医学、生物生物学、地质学和历史文物表征的理解。该仪器的关键功能包括元素定量和数十微米分辨率的绘图。在大气压力下，重元素的检测限为数十 ppm，轻元素分析，适合分析完整和/或活的生物体，以及高通量样品分析与 XRF 相比，具有卓越的分辨率和检测限。和其他 μXRF 仪器将能够对多种生物体中的元素进行定量和分布。元素分布的成像和定量将能够研究元素的迁移性和储存，从而加强对植物矿物质代谢和水生生物中金属定位的研究。还可以分析当地岩石结构中用于可充电电池的稀土元素以及麦基诺州立历史公园的考古文物。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
