0929912Schroeder This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Granted funds will support acquisition of a powder x-ray diffractometer (XRD) to support research in environmental geochemistry, paleoclimatology, economic geology, archeology and geomicrobiology that requires unambiguous mineral phase identification. The new XRD would replace a 20 year old XRD in the Geology Department at the University of Georgia that is no longer supported by a manufacturer. The new instrument will immediately support PI research on the CO2 sequestration potential of iron oxyhydroxide soil minerals studies of the redox sensitivity of radioactive 137Cs on its bioavailability, transport and fate within soils at the DOE Savannah River site, both projects of pressing societal importance. The new XRD will support student training in x-ray diffraction methods for identification of Earth materials and serve as a regional analytical facility for the southeastern U.S. Student trained in modern methods of materials characterization are well poised for future employment in a range of technology sectors.

0929912Schroeder 该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。 拨款将支持购买粉末 X 射线衍射仪 (XRD)，以支持需要明确矿物相识别的环境地球化学、古气候学、经济地质学、考古学和地球微生物学研究。新的 XRD 将取代佐治亚大学地质系已有 20 年历史、不再受制造商支持的 XRD。 新仪器将立即支持 PI 对羟基氧化铁土壤矿物 CO2 封存潜力的研究，以及放射性 137C 的氧化还原敏感性对其在美国能源部萨凡纳河遗址土壤中的生物利用度、运输和归宿的研究，这两个项目都具有紧迫的社会重要性。 新的 XRD 将支持学生在 X 射线衍射方法方面的培训，以识别地球材料，并作为美国东南部的区域分析设施。接受过现代材料表征方法培训的学生将为未来在一系列技术领域的就业做好准备。
