Classic nucleation theory
WebNov 1, 2024 · Classical nucleation theory (CNT) is based on the notion of critical nuclei serving as transition states between supersaturated solutions and growing particles. … WebThe classical nucleation theory recognizes that nucleation is sensitive to any impurities that are found within any system. Even if the impurities are too small to be seen, they still effect the rate of nucleation. Liquid water …

CNT, developed in the first half of the twentieth century, is based on a number of heuristically plausible assumptions and the majority of theoretical work on nucleation is devoted to refining or extending these ideas.
WebApr 11, 2024 · with classical nucleation theory, we investigated the properties of the droplet size distributions as a function of protein concentration. We found that these distributions can be described by a scale-invariant log-normal function with an average that increases progressively as the concentration approaches the critical value from below.
