U.S.-France Cooperative Research: Molecular Theory of the Kinetics of Homogeneous Nucleation

这项为期三年的奖项为美法合作研究提供了支持，该研究旨在开发一种用于过饱和蒸汽中液滴均质成核的全分子理论。加州大学洛杉矶分校的霍华德·赖斯和法国斯特拉斯堡查尔斯·萨德龙研究所的皮埃尔·沙夫的研究小组参与了这项研究。他们建议开展研究，为预测物质的成核率开发一种严格的统计理论。他们的工作将集中在一种单一的物质--氩蒸气上。这位美国调查人员为这次合作带来了理论专业知识。法国调查人员在实验和模拟方面的专业知识补充了这一点。该项目将增进对成核过程的理解，这是大气科学、沸腾和空化、结晶和化学处理、冶金、高能物理、行星形成、轨道形成、超流体和生物过程中的一种普遍现象。

This three-year award provides support for US-France cooperative research aimed at the development of a fully molecular theory for homogenous nucleation of drops in supersaturated vapors. It involves the research groups of Howard Reiss of the University of California at Los Angeles and Pierre Schaaf of the Institute Charles Sadron in Strasbourg, France. They propose studies to develop a rigorous statistical theory for the prediction of nucleation rates in substances. Their work will focus on a single substance - argon vapor. The US investigator brings to this collaboration theoretical expertise. This is complemented by the French investigators' expertise in experimentation and simulation. The project will advance understanding of the process of nucleation, a ubiquitous phenomenon that occurs in atmospheric science, boiling and cavitation, crystallization and chemical processing, metallurgy, high-energy physics, planetary formation, contrail formation, superfluids, and biological processes.
