Early Career: Acquisition of a Powder X-ray Diffractometer for Earth Science Research and Education at Washington University in St. Louis

1161543 catalano1 .这笔拨款支持购买一台x射线衍射仪，以支持地球科学研究和研究培训，这些研究需要能够快速识别细晶和多晶材料的相，以及用于相变和空位取代研究的晶体学结构改进。该仪器将取代圣路易斯华盛顿大学地球和行星科学系老化（30年）和过时的XRD。该仪器将满足华盛顿大学洛杉矶分校七个系的多个教员的研究和培训需求。PIs的早期研究将立即受益于一种新的XRD，用于研究铁氧化物的低温矿化和蚀变，以及研究叶锰酸盐、蒙脱铁和磷酸铀，这对了解水生系统中的污染物命运具有重要意义。该工具将支持现有的PI教育活动，包括本科培训和高中实习活动。＊＊＊

1161543CatalanoThis grant supports acquisition of an x-ray diffractometer to support geoscience research and research training that requires the capability for rapid phase identification of fine grained crystalline and polycrystalline materials and crystallographic structure refinements for studies of phase transformations and vacancy substitutions. The instrument will replace an aging (30 yrs old) and obsolete XRD in the Department of Earth and Planetary Sciences at Washington University in St. Louis. The instrument will serve the research and training needs of multiple faculty at across seven departments at WASH-SL. The lead PIs early career research will immediately benefit from a new XRD for studies of low temperature mineralization and alteration of iron oxides and studies of phyllomanganates, ferrous smectites and uranium phosphates with implications for understanding contaminant fate in aquatic systems. The instrument will support extant PI educational activities including undergraduate training and High-school intern activities. ***
