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

1337450 Elzinga这主要研究仪器（MRI）计划资助支持粉末X射线衍射仪（XRD）的收购，以支持罗格斯大学纽瓦克的研究和研究教育。 XRD将支持Rutgers-Newark（RN）地球环境科学系（DEES）和Rutgers-New Brunswick环境科学系的六个小组的研究计划。 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，以研究：1）土壤中的原生生物矿化过程和调节重金属释放和形态形成的矿物转化（例如，砷、铀）; 2）风成铁向全球海洋输送的矿物学控制及其对初级生产力的影响; 3）混合矿物材料电磁信号的控制实验; 4）矿物学过程对高纬度泥炭土壤甲烷生成的影响; 5）土壤矿物对森林生态系统碳、氮循环的影响。 学生将接受基于XRD的相鉴定和晶体结构细化方法的培训，并将使用XRD对城市受影响的生态系统和土壤进行区域研究。 罗格斯-纽瓦克大学在过去的15年里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.***
