The phenomenon of thermocapillarity, the response of fluids to thermal gradients due to
thermal alteration of their surface tension, was first reported over a century ago. Since then …

Thin, viscous liquid films subjected to impact events can deform. Here we investigate free-
surface oil-film deformations that arise owing to the build up of air under the impacting and …

Manipulation of periodic micro/nanostructures in polymer film is of great importance for
academics and industrial applications in anticounterfeiting. However, with the increasing …

The Marangoni effect describes fluid flow near an interface in response to a surface tension
gradient. Here, we demonstrate that the Marangoni effect is the underlying mechanism for …

The Marangoni effect causes liquids to flow toward localized regions of higher surface
tension. In a thin film, such flow results in smooth thickness variations and may represent a …

Marangoni forces drive a fluid to flow in response to positional differences in surface energy.
In thin polymer films, a difference in surface energy between two coincident liquid polymers …

We study pore nucleation in a model membrane system, a freestanding polymer film.
Nucleated pores smaller than a critical size close, while pores larger than the critical size …

One of the classical limitations for the investigation of the local rheology of small scale soft
objects and/or confined fluids is related to the difficulty to control mechanical contact and its …

We report on the capillary-driven leveling of a topographical perturbation at the surface of a
freestanding liquid nanofilm. The width of a stepped surface profile is found to evolve as the …

We study theoretically and numerically the bending-driven levelling of thin viscous films
within the lubrication approximation. We derive Green's function of the linearized thin-film …
