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 …

Slot die coating is a pre‐metered process commonly used for producing thin and uniform
films. It is an important film fabrication method for applications where precise coating is …

In the last ten years, advances in experimental techniques have enabled remarkable
discoveries of how the dynamics of thin gas films can profoundly influence the behavior of …

An important reason for the century-long debate concerning wetting dynamics is the lack of
decisive information about the contact line. The contact line cannot be treated as a …

After impact onto a smooth dry surface, a drop of viscous liquid initially spreads in the form of
a thick lamella. If the drop splashes, it first emits a thin fluid sheet that can ultimately break up …

Wetting is a prerequisite for coating a uniform layer of liquid onto a solid. Wetting failure and
air entrainment set the ultimate limit to coating speed. It is well known in the coating art that …

In the present study, we experimentally investigate water surface deformation due to the
impact of rounded cylindrical projectiles with different aspect ratios (1.0–8.0). The …

The entrainment of air by advancing contact lines is studied by plunging a solid plate into a
very viscous liquid. Above a threshold velocity, we observe the formation of an extended air …

A liquid drop impacting a dry solid surface with sufficient kinetic energy will splash, breaking
apart into numerous secondary droplets. This phenomenon shows many similarities to …
