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. ***

9807085 Cummings这笔拨款为波特兰州立大学（PSU）应用矿物学实验室（AML）提供了x射线衍射仪（XRD）购置成本的部分支持。AML侧重于矿物的鉴定和定量，以解决环境、地质、工程、农业和工业问题。PI和副PI， Michael Cummings， Georg Grathoff和Carl Palmer，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）装置的主要用户。XRD将被安置在地质系，支持地质系和环境科学与资源项目的教学和研究。在地质系，XRD单元将被整合到地质学本科和研究生课程中。地质系和环境科学与资源方案目前的研究包括：肥料在粘土矿物上的吸附、土壤中粘土矿物的电导率、泥石流的指纹鉴定、将蒙脱石的物理性质与其原子结构联系起来，以及确定与废物隔离和含水层修复有关的阶段。＊＊＊
