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

这一重大研究仪器计划拨款用于支持阿拉斯加大学费尔班克斯分校(UAF)购买粉末X射线衍射仪(XRD)。粉末X射线衍射仪将支持一系列需要对天然和人造材料进行物相鉴定和晶体结构测定的研究。研究各种环境条件下氢氧化铁的界面结构和反应性，研究风化和矿石选矿过程中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，古土壤和火成岩矿物的物相鉴定，以及用于微型电子设备的高温陶瓷和纳米复合压电材料的合成材料的表征，这些都将得到促进。新的粉末X射线衍射仪将是阿拉斯加州第一个最先进的X射线衍射仪，将支持地质和地球物理系、UAF地球物理研究所、化学和生物化学系、植物、动物和土壤科学系、机械工程系、土木与环境工程系、地质工程系、UAF矿物工业研究实验室、石油开发实验室和UAF电子小型化办公室的教职员工和学生的研究。

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.
