Acquisition of an Automated X-ray Powder Diffractometer

小行星9403194 该奖项提供了50%的必要资金，以获得一个新的X射线粉末衍射仪，将安装和运行在地质系在迈阿密大学（俄亥俄州）。该大学致力于提供购买该仪器系统的其余50%的成本。 新的X射线粉末衍射仪将取代过时的1970年仪器，将是唯一的这种仪器在迈阿密校园。衍射仪系统将用于研究项目，包括：1）矿物结构研究; 2）金属间合金无序性及其有序性研究; 3）低温风化环境矿物研究; 4）碳酸盐沉积物来源和运移研究;粘土矿物在钾氩和铷锶定年中的应用研究。 衍射仪也将用于研究生和本科生的教学。 ***

9403194 Hughes This award provides 50 % of the funding necessary to acquire a new x-ray powder diffractometer that will be installed and operated in the Department of Geology at Miami University (Ohio). The University is committed to providing the remaining 50% of the cost of acquiring this instrument system. The new x-ray powder diffractometer will replace an outmoded 1970 instrument and will be the only such instrument on the Miami campus. The diffractometer system will be used in research projects that include : 1) structural studies of minerals, 2) studies of disorder in intermetallic alloys and their hydrides, 3) studies of minerals in the low-temperature weathering environment, 4) studies of the source and transport of carbonate sediments , and 5) investigations of clay minerals related to their use in potassium-argon and rubidium-strontium dating methods. The diffractometer will also be used in graduate and undergraduate teaching. ***
