EAR-0236748LynchAn X-ray diffractometer (XRD) is a fundamental research tool used by a broad cross-section of researchers at Mississippi State University. Recent XRD users have come from the Departments of Geosciences, Plants and Soil Sciences, Chemistry, Biology, Agriculture and Biological Engineering, Mechanical Engineering, and Chemical Engineering. The existing equipment is heavily used through a series of externally funded projects ranging from soil mineralogy, waste disposal, and precision agriculture, through sediment and pollutant transfer in aquifers, to studies on the engineering properties of rocks and sediments in Mississippi and throughout the Southeast. The XRD is also used in applied and theoretical projects directed by the Mississippi Agricultural and Forestry Experimental Station. Dissemination of the results of these projects to the general public is a major activity of the Mississippi State Extension Service, which operates statewide out of the Plants and Soil Sciences Department at MSU. Experience in the XRD laboratory is a fundamental portion of several undergraduate, graduate, and distance-learning "K-12 Teachers in Geoscience" classes. A major concern in the aforementioned research projects is the long time needed to acquire high-quality XRD spectra. NSF support will be used to improve the XRD by purchasing a high-efficiency X-ray detector and monochrometer. These hardware upgrades significantly decrease XRD analysis time and allow large number of samples to be investigated. Funds will also be used to purchase a complete Windows-platform X-ray diffraction database and search/match programs. The software upgrades replace a DOS-platform software package and will make the XRD more "user (student) friendly" and accessible to researchers at the University.***

X射线衍射仪（XRD）是密西西比州立大学广泛使用的基础研究工具。 最近的XRD用户来自地球科学，植物和土壤科学，化学，生物学，农业和生物工程，机械工程和化学工程等部门。 现有的设备被大量使用，通过一系列外部资助的项目，从土壤矿物学，废物处理和精准农业，通过沉积物和污染物在含水层中的转移，对密西西比和整个东南部的岩石和沉积物的工程性质的研究。 XRD还用于密西西比农林实验站指导的应用和理论项目。 向公众传播这些项目的成果是密西西比州推广服务的一项主要活动，该服务在全州范围内由密歇根州立大学植物和土壤科学部负责。 在XRD实验室的经验是几个本科生，研究生和远程学习“K-12地球科学教师”课程的基本组成部分。 上述研究项目中的一个主要问题是需要很长时间才能获得高质量的XRD光谱。 NSF的支持将用于购买高效X射线探测器和单色仪来改进XRD。这些硬件升级显著缩短了XRD分析时间，并允许对大量样品进行研究。 资金还将用于购买一个完整的Windows平台X射线衍射数据库和搜索/匹配程序。 软件升级取代了DOS平台软件包，将使XRD更加“用户（学生）友好”，并可供大学研究人员使用。
