9807085 Cummings This grant provides partial support of the acquisition cost of an X-ray diffractometer (XRD) for the Applied Mineralogy Laboratory (AML) at Portland State University (PSU). The AML focuses on the identification and quantification of minerals to solve environmental, geological, engineering, agricultural, and industrial problems. The PI and Co-PI's, Michael Cummings, Georg Grathoff, and Carl Palmer, in addition to undergraduates, graduate students, faculty and the Portland area scientific community will be the main users of the new X-ray diffraction (XRD) unit. The XRD will be housed in the Geology Department and support teaching and research in the Geology Department and the Environmental Sciences and Resources Program. In the Geology Department the XRD unit will be integrated into the geology undergraduate and graduate curriculum. Current research in the Geology Department and the Environmental Sciences and Resources Program include: adsorption of fertilizers onto clay minerals, electrical conductivity of clay minerals in soils, fingerprinting of debris flows, linking physical properties of smectites to their atomic structure, and the identification of phases associated with waste isolation and aquifer remediation. ***

小行星9807085 该补助金为波特兰州立大学（PSU）的应用矿物学实验室（AML）的X射线衍射仪（XRD）的采购成本提供部分支持。 AML专注于矿物的识别和量化，以解决环境，地质，工程，农业和工业问题。PI和共同PI的，迈克尔卡明斯，格奥尔格格拉索夫，卡尔帕尔默，除了本科生，研究生，教师和波特兰地区的科学界将是新的X射线衍射（XRD）单位的主要用户。 XRD将被安置在地质系，并支持地质系和环境科学与资源计划的教学和研究。在地质系，XRD单元将被纳入地质学本科生和研究生课程。 地质系和环境科学与资源计划目前的研究包括：粘土矿物对肥料的吸附，土壤中粘土矿物的导电性，泥石流的指纹识别，将蒙脱石的物理特性与其原子结构联系起来，以及识别与废物隔离和含水层修复相关的阶段。 ***
