Acquisition of an FTIR for the Nature Research Center, North Carolina Museum of Natural Sciences

“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。”该合同将为购买红外显微镜和傅立叶变换红外光谱仪（FTIR）提供资金。这些仪器将用于测量各种来源的火成岩和变质岩中的磷灰石。数据将发展成过程基础模型，以了解地壳、地幔和火山的地球化学过程。这台乐器将被安置在博物馆里。it’自然研究中心。私家侦探将对整个行动进行监督。维护费用将由国家支持，预计将聘请全职实验室管理人员。PI将使用新的仪器来测量各种磷灰石矿物样品中的水和二氧化碳。各种形式的磷灰石[Ca，Cl], [Ca,CO3], [Ca，OH]允许推断将磷灰石矿物化学与环境条件（流体相，结晶，热力学等）联系起来。FTIR也将用于研究黄铁矿的氧化/水解。重点将放在粘土矿物学上。PI将研究黄铁矿-粘土相互作用的动力学途径，以了解长期元素和化石保存。该仪器将不仅支持PI？但也适用于其他研究领域，包括生物陶瓷、行星地质学和酸性矿山排水。PI与附近的学院和大学的接近和工作关系将使他能够将这种设备提供给代表性不足的学生。科学项目将公开展示。展品将为年轻的学生量身定制，并计划纳入博物馆的PBS节目。* * *

0929898Tacker"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." This award will provide funding to acquire an infrared microscope and Fourier Transform infrared spectrometer (FTIR). The instruments will be used for measuring apatite in igneous and metamorphic rocks of various origins. Data will be developed into process-base models for understanding geochemical processes in the crust, mantle, and volcanoes. The instrument will be housed on-site at the Museum?s Nature Research Center. The PI will have overall operational oversight. Maintenance costs will be supported by the State with full-time laboratory managers expected to be hired. The PI will use the new instrumentation to survey water and carbon dioxide in various apatite-based mineralogical samples. Various forms of apatite [Ca,Cl], [Ca,CO3], [Ca,OH] allow inference to relate apatite mineral chemistry to environmental conditions (fluid phase, crystallization, thermodynamics, etc). The FTIR will also be used to study pyrite oxidation/hydrolysis. Emphasis will be given to clay mineralogy. The PI will study the kinetic pathways of pyrite-clay interactions in order to understand long-term elemental and fossil preservation. The instrumentation will not only support the PI?s research but be applicable to other research foci including bioceramics, planetary geology, and acid mine drainage. The PI's proximity and working relationships with nearby colleges and universities will allow him to make this equipment available to underrepresented students. Scientific projects will be publically displayed. Exhibits will be tailored to younger students and are slated to be incorporated into the Museum's PBS programming. ***
