MRI: Acquisition of a Powder X-Ray Diffractometer for Research and Teaching in Earth and Environmental Sciences at Rutgers University in Newark

1337450 Elzinga这项重大研究仪器(MRI)计划拨款支持购买粉末X射线衍射仪(XRD)，以支持纽瓦克罗格斯大学的研究和研究教育。该研究中心将支持罗格斯-纽瓦克(RN)地球与环境科学系和罗格斯-新不伦瑞克环境科学系的六个小组的研究项目。研究将需要对土壤、沉积物和气溶胶中的细粒矿物相进行表征，以用于以下研究：1)土壤中原生生物矿化过程和调控重金属(如砷、铀)释放和形态的矿物转化；2)风成铁运往世界海洋的矿物学控制及其对初级生产力的影响；3)混合矿物质电磁特征的对照实验；4)矿物学过程对高纬度泥炭土壤甲烷生成的影响；5)土壤矿物质对森林生态系统碳和氮循环的影响研究。学生将接受基于X射线衍射物相鉴定和晶体结构改进方法的培训，并将使用X射线衍射仪对城市受影响的生态系统和土壤进行区域研究。在过去的15年里，罗格斯-纽瓦克大学一直被评为美国种族最多元化的学术机构*

1337450ElzingaThis Major Research Instrumentation (MRI) Program grant supports acquisition of a powder x-ray diffractometer (XRD) to support research and research education at Rutgers University Newark. The XRD will support the research programs of six groups in the Department of Earth & Environmental Sciences (DEES) at Rutgers-Newark (RN) and the Department of Environmental Sciences at Rutgers-New Brunswick. Research will entail characterization of fine grained mineral phases in soils, sediments, and aerosols for studies of: 1) autochthonous biomineralization processes in soils and mineral transformations that regulate the release and speciation of heavy metals (e.g., Arsenic, Uranium); 2) mineralogical controls of eolian Fe transport to the world's oceans and its effect on primary productivity; 3) controlled experiments of the electromagnetic signatures of mixed mineral materials; 4) mineralogical process influence on methanogenesis in high latitude peat soils; and 5) studies of soil mineral influence on forest ecosystem carbon and nitrogen cycling. Students will be trained in methods of XRD-based phase identification and crystallographic structure refinement and will use the XRD for regional studies of urban impacted ecosystems and soils. Rutgers-Newark has been consistently ranked over the last fifteen years as the most ethnically diverse academic institution in the U.S.***
