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. ***

[0420855]在主要研究仪器（MRI）项目的支持下，获得一台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将协助地球科学学院对与酸性矿井排水和地下水中自然存在的砷有关的水样进行元素表征。ICP还将为生物学、化学和地质学教授提供评估自然和人为痕量金属分布的能力，以评估富含蛇纹石的地质地形对小型哺乳动物的生理影响，以及对受威胁和濒危鲟鱼物种的识别和保护。XRD将为地球科学人员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，以及评估与酸性矿山排水相关的硫化物矿物和沉淀盐的矿物组成。XRD将立即对我们的材料研究项目非常有益，该项目获得了NSF拨款DMR-0137323。除了少数例外，所有新的潜在铁电材料都是在当地制备的。每个制备必须是单相的，以产生明确的结果，这是可以实现的，只有使用XRD与每个制备紧密结合。现在有可能在大量有前途的材料中制备单相K2HCr2AsO10、NaSb3F10、YInO3和一系列相关的氧化物，从而可以进行结论性的测量。它还将提高我们在培训和教育新材料科学项目学生方面的分析和研究能力。除了在俄勒冈州立大学进行的合作研究外，XRD和ICP还将为俄勒冈州南部和加利福尼亚州北部地区机构的教师和学生以及社区的地方，州和联邦研究人员提供新的研究机会。＊＊＊
