Dynamics and stability of thin liquid films

WebWhether a lubricant or a coating wets a surface or not is of great technical importance. Theoretically, it is possible to predict the stability of a thin liquid film on a surface, since it is governed by the effective interface potential. In practice, however, a prediction can be quite cumbersome, since liqu WebJan 30, 2024 · The dynamics and stability of thin liquid films have fascinated scientists over many decades.
