Acquisition of a CCD-Detector Single Crystal Diffractometer

0003201Hughes这笔赠款为安装在俄亥俄州迈阿密大学X射线结晶学实验室的带有CCD探测器的单晶X射线衍射仪提供部分支持。这些PI约翰·M·休斯、约翰·拉科万和董海良都来自地质系。该小组包括一名具有丰富单晶X射线经验的职业中期研究人员，以及两名职业生涯早期的研究人员，他们拥有地球科学新兴领域(矿物表面结构和生物矿化)的专业知识。迈阿密大学的学生将广泛参与即将进行的研究。迈阿密大学增加的CCD探测器衍射仪将允许通过X射线结构分析来研究以前太小而无法表征的样品。该仪器将用于研究磷灰石、电气石、粘土矿物和生物矿物等天然材料的材料特性。这些研究在环境矿物学、医学矿物学、地球科学和生物成矿研究中具有重要意义。该设施也将在有时间的情况下供其他研究人员使用。该仪器将安装在迈阿密校区休斯大厅的一个新装修的房间里，并将补充现有的粉末X射线衍射设备、原子力显微镜和单晶X射线相机。除了地球科学仪器和设施计划(EAR/IF)的支持外，俄亥俄州和迈阿密大学也提供了相应的资金。

0003201HughesThis grant provides partial support for a single crystal x-ray diffractometer with a CCD detector, to be housed in the X-ray crystallography laboratory at Miami University, Ohio. The PIs, John M. Hughes, John Rakovan, and Hailiang Dong, are all from the Department of Geology. The group includes a mid-career researcher with extensive single-crystal x-ray experience, and two early-career researchers with expertise in emerging areas of the Earth Sciences (mineral surface structure and biomineralization). Miami University students will be extensively involved in the studies to be undertaken.The addition of the CCD-detector diffractometer at Miami University will allow the investigation of samples that were previously too small for characterization through x-ray structure analysis. The instrument will be used to investigate material properties of natural materials such as apatite, tourmaline, clay minerals, and biominerals. The studies are of importance in the studies of environmental mineralogy, medical mineralogy, earth science, and the formation of minerals by organisms. The facility will also by used by other researchers on a time-available basis. The instrument will be housed in a newly renovated room in Hughes Hall on the Miami campus, and will complement the existing powder x-ray diffraction equipment, atomic force microscope, and single-crystal x-ray cameras. In addition to support from the Earth Sciences Instrumentation and Facilities Program (EAR/IF), matching funds are provided by the State of Ohio and Miami University.***
