MRI: Project Summary - Acquisition of equipment to support environmental materials characterization at the University of Vermont

[0922961] druschel本MRI提案寻求资金以获得材料表征设备。要求在现有的电子显微镜上增加一个波长色散光谱仪（WDS）和一个能量色散光谱仪（EDS），以及一个电子背散射衍射单元（EBSD）。此外，pi还要求配备x射线衍射仪（XRD）、x射线荧光光谱仪（XRF）、拉曼光谱仪和具有数字成像功能的光学显微镜。仪器将用于NSF， EPA， USDA， NOAA, DoD， DOE和其他机构资助的研究。主要研究领域包括了解矿物学对流域养分有效性和流动性的控制，表征流域和临界带微生物-矿物和水的相互作用，表征混合相材料，如沸石和其他微孔矿物基质，了解矿区矿物分布，以及矿物学微观结构对物化条件的控制。在这里进行的基础研究将促进对矿物学表面如何影响地下水、流域和关键地带的污染物和天然化合物运动和分布的认识。这些研究将作为环境科学和工程教育和培训的基础。设备将被纳入课堂和工作坊。这些设备将放置在地质学系最近翻修的现有实验室空间内。pi将组成管理团队，安排培训和管理日常使用。获得资助的研究人员使用该仪器将收取少量费用。将使用在线调度软件征求仪器使用。EDS将升级现有的EM，由全职技术人员管理

0922961Druschel This MRI proposal seeks funding to acquire materials characterization equipment. Requested are a wavelength-dispersive spectrometer (WDS), and energy-dispersive spectrometer (EDS), and an electron-backscatter-diffraction unit (EBSD) to be added to an existing electron microscope. In addition, the PIs are requesting an x-ray diffractometer (XRD), and x-ray fluorescence spectrometer (XRF), a Raman spectrometer, and an optical microscope with digital imaging capabilities. Instrumentation will be put to use in NSF, EPA, USDA, NOAA, DoD, DOE and other agency-funded research. Major research areas involve understanding mineralogical controls on nutrient availability and mobility in watersheds, characterizing microbial-mineral and water interactions in watersheds and the critical zone, characterizing mixed phase materials such as zeolites and other microporous mineral matrices, understanding mineral distributions at mining sites, and physicochemical condition control by mineralogical microstructure. The fundamental research to be undertaken here will advance the state of knowledge for how mineralogical surfaces impact contaminant and natural compound movement and distribution in groundwaters, watersheds and in the critical zone. The studies will server as a foundation for education and training for environmental science and engineering. Equipment will be incorporated into classes and workshops. The equipment will be placed in recently-renovated existing laboratory space within the Department of Geology. The PIs will comprise the management team and will arrange training and administer day-to-day usage. Funded researchers will be charged a small fee to use the instrumentation. Online scheduling software will be used to solicit instrument use. The EDS will upgrade an existing EM, which is administered by a full-time technician.***
