In the course of evolution nature has arrived at startling materials solutions to ensure
survival. Investigations into biological surfaces, ranging from plants, insects and geckos to …

Surfactant-mediated wetting and spreading are ubiquitous. Understanding of these
phenomena in-depth allows precise tailoring of wetting performance which can contribute to …

Cells compartmentalize parts of their interiors into liquid-like condensates, which can be
reconstituted in vitro. Although these condensates interact with membrane-bound …

Spraying occurs by the impact of water droplets on the superhydrophobic wire meshes by
liquid penetration during the spreading and recoiling. We have shown that adding a small …

Despite intensive investigations on the droplet receding contact angle on superhydrophobic
surfaces, ie, a key parameter characterizing surface wettability and adhesion, the …

Abstract The classic Cassie-Baxter equation has been used for decades to describe the
equilibrium contact angle of a droplet on a partially wetted, rough substrate and inspired …

Drop impact on solid surfaces is encountered in numerous natural and technological
processes. Although the impact of single-phase drops has been widely explored, the impact …

Previous studies revealed that the perpendicular impact of low-viscosity droplets on
sufficiently lyophobic surfaces would stimulate a liquid jet during droplet recoiling, and in …

Controlling the impact of water droplets on nonwetting surfaces is difficult due to their
superior liquid repellency. Herein, we experimentally demonstrate that the impact dynamics …

A thin liquid droplet spreads on a soft viscoelastic substrate with arbitrary rheology.
Lubrication theory is applied to the governing field equations in the liquid and solid domains …
