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

0420855埃利奥特在重大研究仪器(MRI)计划的支持下，收购一台X射线衍射仪(X射线衍射仪)和电感耦合等离子光谱仪(ICP)将显著改善南俄勒冈大学(SOU)的地球科学、材料和环境研究设施。国际比较方案将协助地球科学学院对与酸性矿山废水和地下水中自然存在的砷有关的水样进行元素表征。国际生物化学联合会还将为生物、化学和地质系提供评估自然和人为痕量金属分布的能力，评估富含蛇纹石的地质地形对小型哺乳动物的生理影响，以及识别和保护受威胁和濒危的鲟鱼物种。X射线衍射仪将为地球科学教师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，并评估与酸性矿山废水有关的硫化物矿物和沉淀盐的矿物组成。X射线衍射仪将立即对我们的国家科学基金资助DMR-0137323下的材料研究计划大有裨益。所有新的潜在铁电材料都是当地生产的，几乎没有例外。每一种制备都必须是单一相才能产生确定的结果，这只能通过将X射线衍射法与每一种制备密切结合使用来实现。现在将有可能在大量有希望的材料中制备单相K2HCr2AsO10、NaSb3F10、YInO3和一系列相关氧化物，以便进行确凿的测量。它还将提高我们的分析和研究能力，培训和教育我们的新材料科学专业的学生。除了在南加州大学开展的合作研究外，该中心还将为俄勒冈州南部和加利福尼亚州北部地区机构的教职员工和学生以及社区中的地方、州和联邦研究人员提供新的研究机会。***

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. ***
