Acquisition of a New In Situ Near- Atomic Resolution Hydrothermal System and Automated BET Equipment for Surface Area Analysis

小行星9529258 这笔赠款提供了154，875美元，作为购买新的原位近原子分辨率水热系统和自动BET设备的部分支持，用于在溶解和沉淀动力学研究中分析矿物表面。 该水热系统将是定制的，专门用于晶体表面溶解和沉淀速率的微尺度分析，而Brunauer-Emmett-Teller（BET）仪器将是“现成的”购买，用于确定矿物粉末的反应表面积。 硅酸盐矿物反应动力学的确定是低温地球化学研究的核心，对理解环境地球化学过程至关重要。 ***

9529258 Lasaga This grant provides $154,875 as partial support of the costs of acquiring a new in-situ near- atomic resolution hydrothermal system and automated BET equipment for analysis of mineral surfaces in studies of dissolution and precipitation kinetics. The hydrothermal system will be custom built and used specifically for micro-scale analyses of dissolution and precipitation rates at crystal surfaces while the Brunauer-Emmett-Teller (BET) instrument will be purchased "off-the-shelf" and used for determination of reactive surface area of mineral powders. Determination of the reaction kinetics of silicate minerals is central to low temperature geochemical research and is essential to an understanding of environmental geochemical processes. ***
