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

这个为期三年的奖项为美国和法国的合作研究提供了支持，旨在开发一种全分子理论，用于过饱和蒸汽中液滴的均匀成核。该研究由加州大学洛杉矶分校的Howard Reiss和法国斯特拉斯堡Charles Sadron研究所的Pierre Schaaf组成。他们建议研究发展一套严格的统计理论，以预测物质的成核速率。他们的工作将集中在一种物质上——氩蒸气。美国研究者为这一合作带来了理论专长。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。该项目将促进对成核过程的理解，这是一种在大气科学、沸腾和空化、结晶和化学加工、冶金、高能物理、行星形成、尾迹形成、超流体和生物过程中普遍存在的现象。

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.
