This study presents the spreading of a single filament of a yield stress (viscoplastic) fluid
extruded onto a pre-wetted solid surface. The filaments spread laterally under surface …

The spreading under surface tension and gravity of a droplet of yield-stress fluid over a thin
film of the same material is studied. The droplet converges to a final equilibrium shape once …

The evolution of the liquid bridge formed between two coalescing sessile yield-stress drops
is studied experimentally. Surprisingly, we find that the height of the bridge evolves similar to …

Reduced graphene oxide (rGO) thin films have demonstrated various advantages in flexible
electronics. So far, solution processes are widely used for making rGO thin films for their mild …

Superelevation of the side edge, also known as heavy edge, is a defect that negatively
affects Li-ion battery manufacturing and needs to be mitigated. In this study, we …

We study the axisymmetric evolution of a liquid film on a solid sphere governed by gravity,
capillarity and viscous forces. The lubrication equations established in spherical coordinates …

We describe a setup to perform systematic studies on the spreading of droplets of complex
fluids under microgravity conditions. Tweaking the gravitational acceleration under which …

Air entrapment during the drop impact on a liquid surface is crucial to the ocean–
atmosphere mass transfer process. Herein, we report a new mechanism of air entrapment …

When a particle, such as dust, contacts a thin liquid film covering a surface it is trapped by
the liquid. This effect is caused by the formation of a meniscus, resulting in a capillary force …

Despite tremendous interest in the wetting dynamics at the microscale, attention to
nanodroplets has started rising only over the last two decades. In the current work, we …
