MRI: Acquisition of a High Resolution Mapping Raman Microprobe for Research and Teaching

1428857埃尔伍德-马登这项重大研究仪器(MRI)计划拨款支持购买成像拉曼显微镜，以便对地质、生物、环境、考古和工程材料进行无损、高分辨率(微米级)和时间分辨的研究。拉曼显微镜将拥有自动化的x-y-z可平移工作台、双波长激光激发源和可变温度(-196至600摄氏度)样品室。将利用拉曼系统进行的具体研究将包括对矿物表面流体蚀变和风化过程的现场观察，对永久冻土和深海环境中气体笼合物形成和解离过程的研究，对生物中介材料腐蚀过程的研究，以及对天然和受污染系统中痕量金属形态和氧化/还原机制的研究。该仪器将服务于俄克拉荷马州几个系的教职员工和他们的学生，PI打算通过该大学现有的路易斯·斯托克斯少数民族参与科学、技术、工程和数学项目，让代表不足的学生参与体验式学习。***

1428857Elwood-MaddenThis Major Research Instrumentation (MRI) Program grant supports acquisition of an imaging Raman microscope to allow for non-destructive, high resolution (micron scale) and time resolved studies of geological, biological, environmental, archeological, and engineered materials. The Raman microscope would have automated x-y-z translatable stage, dual-wavelength laser excitation sources, and variable temperature (-196 to 600 degree C) sample chamber. Specific studies that would take advantage of the Raman system would include in situ observations of fluid alteration and weathering processes at mineral surfaces, studies of gas clathrate formation and dissociation processes in permafrost and deep-sea environments, studies of biologically mediated material corrosion processes, and trace metal speciation and oxidation/reduction mechanisms in natural and contaminated systems. The instrument would serve faculty and their students across several departments at Oklahoma and the PIs intend to engage underrepresented students in experiential learning through an extant Louis Stokes Alliance for Minority Participation in Science, Technology, Engineering, and Mathematics program at the University. ***
