0115647PutirkaThis grant, made through the Major Research Instrumentation Program, provides partial support of the costs for development of an x-ray fluorescence (XRF) laboratory at the Indiana University of Pennsylvania (IUP). This grant includes acquisition of a Philips MagiX Pro x-ray fluorescence spectrometer. The new laboratory will represent the only XRF facility in the western PA region, and will thus satisfy a crucial need within the region for a flexible and precise chemical analysis tool. In particular, this laboratory will support a wide range of research activities at IUP, Penn State and the University of Pittsburgh. For reasons of flexibility, this instrument includes a He attachment, which allows for the analysis of liquid and loose powder samples, and a new crystal developed by Philips (PX-9), which increases the intensity gain on transition and rare earth elements by a factor of 1.5-1.8, compared to the LiF (200) crystal. This grant also includes funds for an array of sample preparation equipment, including furnaces, crucibles and a Claise fusion machine for the preparation of glass beads, and a press and ancillary equipment for the preparation of pressed powder pellets. The research activities at IUP that will be supported by this acquisition include: 1) An investigation of the volcanic plumbing systems within the Snake River Plain, Idaho, and at Mauna Kea volcano, Hawaii. 2) An unraveling of the paleoclimate record contained in terrigenous sediments recovered from deep-sea cores. 3) The elucidation of crystal structures and defects of organic and inorganic substances. 4) A study of InAs/InxGa1-xSb and GaN/GaxIn1-x solid solutions, which are being developed as electronic devices. This laboratory facility will also provide a central component to curriculum revisions at IUP that aim toward a seamless incorporation of research and undergraduate coursework. A new course will be developed that will be devoted to the instruction of analytical methods. Several of our existing courses (Mineralogy, Geochemistry, X-ray Crystallography, Igneous and Metamorphic Petrology) will also be revised to incorporate meaningful research components. IUP's existing General Chemistry sequence will also be modified so that students at the freshmen/sophomore level are introduced to XRF analytical techniques; analytical methods will thus be reinforced throughout the undergraduate curriculum. ***

0115647 putirkathis Grant是通过主要研究工具计划制定的，为宾夕法尼亚州印第安纳大学（IUP）的X射线荧光（XRF）实验室的开发成本提供了部分支持。该赠款包括收购Philips Magix Pro X射线荧光光谱仪。新实验室将代表西部宾夕法尼亚州西部地区唯一的XRF设施，因此满足了该区域内的至关重要需求，即灵活，精确的化学分析工具。特别是，该实验室将支持IUP，宾夕法尼亚州立大学和匹兹堡大学的广泛研究活动。出于灵活性的原因，该仪器包括HE附件，该仪器可以分析液体和散粉样品，以及由飞利浦（PX-9）开发的新晶体，与LIF（200）晶体相比，该仪器的过渡强度增加和稀土元素的强度增长和稀土元素增加了1.5-1.8。该赠款还包括用于一系列样品准备设备的资金，包括炉子，坩埚和用于制备玻璃珠的养护机，以及用于制备压制粉末颗粒的压力和辅助设备。此次收购将支持IUP的研究活动包括：1）对爱达荷州蛇河平原内的火山管道系统进行调查，以及在夏威夷的Mauna Kea Volcano。 2）从深海核心回收的陆源沉积物中包含的古气候记录的揭开。 3）阐明有机和无机物质的晶体结构和缺陷。 4）INAS/INAS/INXGA1-XSB和GAN/GAXIN1-X固体溶液的研究，它们作为电子设备开发。该实验室设施还将为IUP的课程修订提供一个核心组成部分，旨在将研究和本科课程无缝纳入。将开发一门新课程，该课程将用于分析方法的指导。我们现有的几门课程（矿物学，地球化学，X射线晶体学，火成岩和变质岩学）也将进行修改，以结合有意义的研究组件。 IUP现有的一般化学序列也将进行修改，以便将新生/大二学生一级的学生引入XRF分析技术。因此，分析方法将在整个本科课程中得到加强。 ***
