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

9529258 Lasaga这笔赠款提供154,875美元，作为购买新的就地近原子分辨水热系统和用于在溶解和沉淀动力学研究中分析矿物表面的自动化BET设备的部分费用。水热系统将是定制的，专门用于晶体表面的溶解和沉淀速率的微观分析，而Brunauer-Emmett-Teller(BET)仪器将购买现成的，用于测定矿物粉末的反应表面积。测定硅酸盐矿物的反应动力学是低温地球化学研究的核心，也是理解环境地球化学过程的关键。***

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. ***
