MRI-R2: Acquisition of an XRD, FTIR, and WDS for Integrated Mineralogical and Geochemical Studies at Middlebury College

[09959306] ryan：该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。这项主要研究仪器回收和再投资（MRI-R2）计划资助购买x射线衍射仪（XRD）和波长色散光谱仪（WDS），这些仪器将与米德尔伯里学院现有的扫描电子显微镜相匹配。XRD将支持需要矿物相识别和晶体结构细化的研究，并将配备温度控制的样品台，以便进行动力学研究。配备了扫描电镜的WDS将允许对固体材料进行微化学分析。PI研究将包括研究来自佛蒙特州北部的含水层岩石和地下水中的砷物种，以评估毒性和来源。现有的FTIR将支持这项研究。所申请仪器的其他研究应用将包括研究湖泊和海洋沉积物和土壤矿物中记录的第四纪气候。所要求的仪器将支持PI研究和本科生研究培训在这所文理学院位于佛蒙特州，EPSCoR州，以及来自地区机构的合作者。这笔拨款与ARRA的目标非常一致，因为要购买的设备将通过支持美国员工的仪器制造商美国销售办事处购买

0959306RyanThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Major Research Instrumentation Recovery and Reinvestment (MRI-R2) Program grant supports acquisition of x-ray diffractometer (XRD) and a wavelength dispersive spectrometer (WDS) that will be mated to an existing scanning electron microscope at Middlebury College. The XRD will support research requiring mineral phase identification and crystallographic structure refinements and will be outfitted with a temperature controlled sample stage to allow for kinetic studies. The SEM equipped WDS will allow for microchemical analysis of solid materials. PI research will include studies of arsenic speciation in aquifer rocks and groundwaters from northern Vermont to evaluate toxicity and sources. An existing FTIR will support this research. Other research application of requested instruments will include studies of Quaternary climate as recorded in lake and marine sediments and soil minerals. The requested instruments will support PI research and undergraduate student research training at this liberal arts college located in Vermont, an EPSCoR state, as well as collaborators from regional institutions. The grant is well aligned with ARRA goals as the equipment to be purchased will be through instrument manufacturer U.S. sales offices that support U.S. employees.***
