U.S.-France Cooperative Research: Equilibrium Properties of Aqueous Solutions at Superambient Temperatures

这个为期三年的奖项将支持华盛顿大学的Everest L. Shock和Blaise Pascal大学的Vladimir Mayer在地球化学方面的美法合作研究。他们的研究目的是通过实验测量来测试各种无机和有机水流体的热力学数据模型。矿物、气体、有机化合物、微生物和人类活动的副产品通过地壳相对较浅区域的含水流体接触到。这些液体促进了反应，否则反应会迟缓。准确的热力学数据溶解离子，电解质，气体，和有机化合物需要开发预测模型。肖克博士为这次合作带来了他在理论地球化学方面的专业知识。他开发了一个模型，用于预测数千种含水有机和无机物质的热力学数据。在高温下，数据不完整或完全缺乏。法国研究人员梅尔博士多年来一直致力于对这些物种进行高温测量。他的实验工作将为扩展现有模型的准确性和适用性提供所需的高温数据。他们的共同努力将促进我们对地下地球过程的理解，并改善目前遏制并最终避免环境问题的努力。* * *

*** 9415558 Shock This three-year award will support U.S.-France cooperative research in geochemistry between Everest L. Shock of Washington University and Vladimir Mayer of the University of Blaise Pascal. The objective of their research is to test models of thermodynamic data with experimental measurements for a wide variety of aqueous inorganic and organic fluids. Minerals, gases, organic compounds, microorganisms and the byproducts of human activity are brought into contact by aqueous fluids in relatively shallow regions of the earth's crust. These fluids facilitate reactions which would otherwise be sluggish. Accurate thermodynamic data for dissolved ions, electrolytes, gases, and organic compounds are needed to develop predictive models. Dr. Shock brings to this collaboration his expertise in theoretical geochemistry. He has developed a model for prediction of thermodynamic data for thousands of aqueous organic and inorganic species. Data are incomplete or wholly lacking at high temperatures. The French investigator, Dr. Mayer, has worked for a number of years in the generation of high temperature measurements for these species. His experimental work will provide the high temperature data that are needed to extend the accuracy and applicability of the existing model. Their joint effort will advance our understanding of sub-surface earth processes and improve current efforts to contain, and eventually avoid environmental problems. ***
