TL;DR: A single thin-film model captures quantitatively the characteristics of the complete evolution of the rim observed in the experiments and explains how the development and macroscopic morphology are controlled by the slip of the film on the substrate.

TL;DR: In this paper, a two-dimensional phase field model for solid state dewetting where the surface energy is weakly anisotropic is proposed, and the corresponding sharp interface limit is derived via matched asymptotic analysis involving multiple inner layers.

TL;DR: An unexpected observation is that droplets with identical volumes synchronise their motion and become independent of the initial geometry long time before equilibrium is reached.

TL;DR: The direct numerical simulation allows new insight into the conduction mechanisms for different frequency regimes, and numerically computed values for the degree of dissociation are of the same order of magnitude as the values obtained with classical formulas, but still differ by a factor of about 1/3.

TL;DR: In this paper, the axisymmetric flow of a thin liquid film is considered for the problem of a vertically rotating disk that is partially immersed in a liquid bath, and a model for the fully three-dimensional free boundary problem of the rotating disk, that drags a thin film out of the bath is set up.
