This critical review discusses the current understanding of the formation, transport, and
merging of drops in microfluidics. We focus on the physical ingredients which determine the …

We study experimentally the behaviour of a drop deposited on a conical fibre. It is shown
that for wetting liquids, such a drop spontaneously moves towards the region of lower …

We discuss in this paper the nature of the friction generated as a drop glides on a textured
material infused by another liquid. Different regimes are found, depending on the viscosities …

Insects provide examples of many cunning stratagems to cope with the challenges of living
in a world dominated by surface forces. Despite being the current masters of the land …

Many microfluidics devices, coating processes, or diphasic flows involve the motion of a
liquid meniscus on a wet wall. This motion induces a specific viscous force, that exhibits a …

The classic description of the rate of capillary rise given by the Washburn equation, which
assumes that the contact angle preserves the equilibrium value at all times, has been …

We describe the physics behind a peculiar feeding mechanism of a certain class of
shorebirds, in which they transport their prey in droplets from their beak tips mouthwards …

In this paper, a series of experiments were performed to investigate the effects of
superhydrophilic and hydrophilic surfaces on the heat transfer performance and slug motion …

Interplay between capillary, gravity and viscous forces in unsaturated porous media gives
rise to a range of complex flow phenomena affecting morphology, stability and dynamics of …

We consider experimentally the viscous fingering problem wherein a silicone oil displaces a
Carbopol gel in a rectangular Hele-Shaw cell. Unlike traditional cases, the displacing fluid …
