Acquisition of a Powder X-Ray Diffractometer for the Applied Mineralogy Laboratory at Portland State University

9807085卡明斯这笔赠款为波特兰州立大学应用矿物学实验室购买X射线衍射仪提供部分支持。反洗钱侧重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Co-Pi、Michael Cummings、Georg Grathoff和Carl Palmer，以及本科生、研究生、教职员工和波特兰地区科学界将是新的X射线衍射仪的主要用户。该研究所将设在地质系，支持地质系和环境科学与资源计划的教学和研究。在地质学系，地质学专业将纳入地质学本科生和研究生课程。地质部和环境科学与资源计划目前的研究包括：肥料在粘土矿物上的吸附、粘土矿物在土壤中的导电性、泥石流的指纹、蒙脱石的物理性质与其原子结构之间的联系，以及与废物分离和含水层修复相关的相识别。***

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. ***
