Purchase of a New X-Ray Diffraction System

该合同提供购买X射线衍射仪(XRD)系统所需资金的一半，该系统将在西南密苏里州立大学的地理、地质和规划系安装和运行。该大学承诺提供所需的剩余资金。该系统将主要供地理、地质和规划系的学生和教职员工以及来自农业、化学和物理系的其他校园用户使用。目前需要具有X射线衍射系统能力的正在进行的项目包括：分析密苏里州冰川沉积物的粘土矿物学以进行地层排序，密苏里州元古界花岗岩的矿物学研究，土壤研究，以及确定离子络合物对粘土矿物晶体结构及其性质的影响。

This award provides one-half the funding required to purchase an X-ray diffractometer (XRD) system to be installed and operated in the Department of Geography, Geology, and Planning at Southwest Missouri State University. The University is committed to providing the remaining funds necessary. The XRD system will be used primarily by students and faculty of the Department of Geography, Geology, and Planning, as well as other campus users from the departments of Agriculture, Chemistry and Physics. Currently active projects needing the capability of the XRD system include: analyzing the clay mineralogy of glacial sediments in Missouri for stratigraphic ordering, mineralogical studies of the Proterozoic granites of Missouri, soils studies, and determining the effect of ionic complexes on the crystal structure of clay minerals and their properties.
