0744230PariseFunds will support acquiring an X-Ray powder diffractometer for the Department of Geoscience?s X-ray Scattering Facility (InXS) at Stony Brook. The instrument will support investigators from the Geosciences, Chemistry, Marine Sciences and Material Science departments. The InXS user base comprises 14 research groups. A Rigaku Ultima III instrument is requested with Cross Beam Optic (CBO) technology providing fast user switching between Bragg-Brentano (B-B) and parallel beam (PB) optics, allowing flat plate or cylindrical sample analysis. A Rigaku z-translation furnace will also be purchased, allowing thermal expansion measurements. Proposed studies fall into several broad categories; Geo-nano-materials, elemental analysis will help elucidate contaminant recycling (FeS, Ferrihydrite, etc) and biogechemical processes (bone and shell growth). Materials research, amorphous calcium carbonate (ACC) formation and dissociation dynamics will be studied to enhance biomaterials design and nano-perovskite material synthesis will be determined under different temperature regimes. Mineral physics, high P and T relation to crystalline structure, rheology, strength and elasticity will be elucidated. Low temperature geochemistry, arsenic removal strategies will be evaluated, synthetic basalts will be used as a proxy to study maritan geochemical processes, and mineral interactions during early organic matter diagenesis will be assessed. Additional analyses will be made using the new instrumentation in crystalline materials research. The requested instrument will represent a robust resource offering graduate students access to hands on analyses. The rapid configuration capabilities of the requested instrument will allow unique and advanced teaching opportunities. The instrument will be incorporated into several courses. InXS facility members provide service through seminars, REU, IGERT, teacher workshops, and other outreach vehicles.***

0744230巴黎基金会将支持为地球科学系购买一台X射线粉末衍射仪？位于斯托尼布鲁克的X射线散射装置（InXS）。该仪器将为地球科学、化学、海洋科学和材料科学部门的研究人员提供支持。InXS用户群由14个研究小组组成。Rigaku Ultima III仪器需要交叉光束光学（CBO）技术，用户可在Bragg-Brentano（B-B）和平行光束（PB）光学器件之间快速切换，允许平板或圆柱形样品分析。还将购买理学z平移炉，用于热膨胀测量。拟议的研究分为几大类;地质纳米材料，元素分析将有助于阐明污染物回收（FeS，Ferrihydrate等）和生物化学过程（骨和壳生长）。材料研究，无定形碳酸钙（ACC）的形成和分解动力学将被研究，以加强生物材料的设计和纳米钙钛矿材料的合成将在不同的温度制度下确定。矿物物理，高P和T晶体结构，流变学，强度和弹性的关系将得到阐明。低温地球化学，砷去除策略将被评估，合成玄武岩将被用作研究海洋地球化学过程的替代物，早期有机质成岩作用期间的矿物相互作用将被评估。将使用晶体材料研究中的新仪器进行额外的分析。所要求的工具将代表一个强大的资源，为研究生提供动手分析的机会。所需仪器的快速配置功能将提供独特和先进的教学机会。该工具将纳入若干课程。InXS设施成员通过研讨会、REU、IGERT、教师研讨会和其他外展工具提供服务。*
