9634143 Eggleston This grant provides $88,976 as partial support of the costs of acquiring a scanning probe microscope system (SPM) at the University of Wyoming. This instrument will allow high resolution (sub-nano scale) imaging of electrostatic forces on mineral and/or material surfaces. As such, it can be used to study the in situ redox conditions at site-specific mineral surfaces, allowing an understanding of the kinetics of oxidation of sulfide minerals. Additionally, the imaging capabilities of the SPM WILL be used for high-resolution studies of mineral dissolution and precipitation mechanisms. This facility will benefit a wide range of researchers within the Department of Geology and also within the Departments of Chemistry, Zoology and Physiology. ***

小行星9634143埃格莱斯顿 该补助金提供88，976美元，作为在怀俄明州大学购买扫描探针显微镜系统（SPM）的部分支持。 该仪器将允许对矿物和/或材料表面上的静电力进行高分辨率（亚纳米尺度）成像。 因此，它可以用来研究在现场特定的矿物表面的氧化还原条件，允许硫化矿物氧化动力学的理解。 此外，SPM的成像能力将用于矿物溶解和沉淀机制的高分辨率研究。 该设施将使地质学系以及化学、动物学和生理学系的广泛研究人员受益。 ***
