Acquisition of a high resolution ICP & XRD for environmental, Earth, & material science research in biology, Chemistry, Geology, & Physics at Southern Oregon University

0420855埃利奥特在主要研究仪器（MRI）计划的支持下，购买X射线衍射仪（XRD）和电感耦合等离子体光谱仪（ICP）将显著改善南俄勒冈州大学（SOU）的地球科学、材料和环境研究设施。 ICP将协助地球科学系对与酸性矿井排水和地下水中天然存在的砷有关的水样进行元素表征。 ICP还将提供生物学，化学和地质学系评估自然和人为微量金属分布对小型哺乳动物的蛇纹丰富的地质地形的生理影响，以及对受威胁和濒危鲟鱼物种的识别和保护的能力。 XRD将为地球科学系提供识别未知矿物的能力，研究导致泥岩中各种粘土矿物形成的分布和环境条件，并评估与酸性矿山排水相关的硫化物矿物和沉淀盐的矿物学成分。 XRD将立即对我们在NSF资助DMR-0137323下的材料研究计划非常有益。 所有新的潜在的铁电材料检查本地制备，除了少数例外。 每个制备必须是单相的，以产生确定的结果，这只能通过使用XRD与每个制备密切结合来实现。在大量积压的有前途的材料中，现在可以制备单相K2 HCr 2AsO 10、NaSb 3F 10、YInO 3和一系列相关的氧化物，从而可以进行结论性的测量。 它还将提高我们的分析和研究能力，培训和教育学生在我们的新材料科学计划。 除了在SOU进行的合作研究，XRD和ICP还将为整个俄勒冈州南部和北方加州以及当地，州和社区的联邦研究人员的区域机构的教师和学生提供新的研究机会。 ***

0420855ElliotWith support form the Major Research Instrumentation (MRI) Program, the acquisition of an x-ray diffractometer (XRD) and inductively coupled plasma spectrometer (ICP) will significantly improve the earth science, materials, and environmental research facilities at Southern Oregon University (SOU). The ICP will assist earth science faculty with elemental characterization of water samples associated with acid mine drainage and naturally occurring arsenic in groundwater. The ICP will also provide biology, chemistry, and geology faculty with the ability to evaluate natural and anthropogenic trace metal distributions on the physiological effects of serpentine-rich geologic terrains on small mammals and on the identification and protection of threatened and endangered sturgeon species. The XRD will provide earth science faculty the capability of identifying unknown minerals, studying the distribution and environmental conditions that result in the formation of various clay minerals within mudrocks, and assessing the mineralogical composition of sulfide minerals and precipitated salts associated with acid mine drainage. The XRD will immediately be highly beneficial to our materials research program under NSF grant DMR-0137323. All new potentially-ferroelectric materials examined are locally prepared, with few exceptions. Each preparation must be single phase to produce definitive results and this is achievable only by using XRD in close conjunction with each preparation. It will now become possible to prepare single phase K2HCr2AsO10, NaSb3F10, YInO3 and a series of related oxides, among a large backlog of promising materials, so that conclusive measurements can be made. It will also improve our analytical and research capability in training and educating students in our new Material Sciences program. In addition to the collaborative research conducted at SOU, the XRD and ICP will also provide new research opportunities for faculty and students at regional institutions throughout southern Oregon and northern California as well as local, state, and federal researchers in the community. ***
