Acquisition of an X-ray Powder Diffractometer for Research in Geological, Archeological, and Geomicrobiological Sciences

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。获得的资金将用于购买粉末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将取代乔治亚大学地质系已有20年历史的XRD，该XRD不再由制造商提供支持。新仪器将立即支持PI研究氢氧化铁土壤矿物的二氧化碳封存潜力，研究放射性137Cs在美国能源部萨凡纳河遗址土壤中的生物有效性，运输和命运的氧化还原敏感性，这两个项目都具有紧迫的社会重要性。新的x射线衍射仪将支持学生进行x射线衍射方法鉴定地球材料的培训，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。

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.
