MRI: Acquisition of Modern Analytical X-Ray Diffraction Instrumentation at the University of Alaska Fairbanks

从这个主要研究仪器计划赠款资金支持在阿拉斯加大学费尔班克斯（UAF）的粉末X射线衍射仪（XRD）的收购。 粉末XRD将支持一系列需要对天然和人造材料进行相鉴定和晶体结构测定的研究。 研究一系列环境条件下铁羟基氧化物的界面结构和反应性，研究通过风化和矿石矿物加工释放到环境中的过渡金属的相关系、形态和分配行为，研究北极冰-卤水系统的矿物学，古土壤和火成岩形成矿物的相鉴定，和用于小型化电子器件的包括高温陶瓷和纳米复合压电材料的合成材料的表征都将得到促进。 新的粉末XRD将是阿拉斯加州第一个最先进的XRD，将支持地质和地球物理系，UAF地球物理研究所，化学和生物化学，植物，动物和土壤科学，机械工程，土木和环境工程，地质工程，UAF矿业研究实验室，石油开发实验室，和UAF电子微型化办公室。

Funding from this Major Research Instrumentation Program grant supports acquisition of a powder x-ray diffractometer (XRD) at the University of Alaska Fairbanks (UAF). The powder XRD will support a range of research requiring phase identification and crystallographic structure determinations of natural and man made materials. Studies of the interface structure and reactivity of iron oxyhydroxides under a range of environmental conditions, studies of phase relationships, speciation and partitioning behavior of transition metals that are released to the environment via weathering and ore mineral processing, studies of the mineralogy of artic ice-brine systems, phase identification of paleosols and igneous rock forming minerals, and characterization of synthetic materials including high temperature ceramics and nanocomposite piezoelectric materials for use in miniaturized electronic devices will all be facilitated. The new powder XRD would be the first state-of-the-art XRD in the state of Alaska and will support faculty and student research across the Departments of Geology and Geophysics, the UAF Geophysical Institute, Chemistry and Biochemistry, Plant, Animal and Soil Science, Mechanical Engineering, Civil and Environmental Engineering, Geological Engineering, the UAF Mineral Industry Research Laboratory, the Petroleum Development Laboratory, and the UAF Office of Electronic Miniaturization.
