The speed at which a liquid can move over a solid surface is strongly limited when a three-
phase contact line is present, separating wet from dry regions. When enforcing large contact …

The merging of two fluid drops is one of the fundamental topological transitions occurring in
free surface flow. Its description has many applications, for example, in the chemical industry …

Triboelectric nanogenerators (TENGs) are cutting-edge technology that converts mechanical
energy into electrical energy through contact electrification (CE). The CE process involves …

In this paper we investigate the implementation of contact angles in the pseudopotential
lattice Boltzmann modeling of wetting at a large density ratio ρ L/ρ V= 500. The …

Dynamic wetting is a ubiquitous phenomenon and frequently observed in our daily life, as
exemplified by the famous lotus effect. It is also an interfacial process of upmost importance …

More than one century ago, Lippmann found that capillary forces can be effectively
controlled by external electrostatic forces. As a simple example, by applying a voltage …

Liquid drops start spreading directly after coming into contact with a solid substrate.
Although this phenomenon involves a three-phase contact line, the spreading motion can be …

Hypothesis Droplet spreading governs various daily phenomena and industrial processes.
Insights about microdroplet spreading are limited due to experimental difficulties arising from …

Hypothesis Droplet coalescence is a common phenomenon and plays an important role in
many applications. When two liquid droplets are brought into contact, a liquid bridge forms …

A survey of recent literature on wetting phenomena reveals that there is a fast-growing
interest in wetting of soft or deformable substrates, due to its potential applications in many …
