This work presents a combined experimental and theoretical study of dynamic contact angle hysteresis using liquid bridges under cyclic compression and stretching between two identical plates. Under various loading rates, contact angle hysteresis for three different liquids was measured by examination of advancing and receding angles in liquid bridges, and the capillary forces were recorded. It is found that, for a given liquid, the hysteretic phenomenon of the contact angle is more pronounced…

Closed-Form Expressions for Contact Angle Hysteresis: Capillary Bridges between Parallel Platens
A closed form expression capable of predicting the evolution of the shape of liquid capillary bridges and the resultant force between parallel platens is derived. Such a scenario occurs within many
Dynamic stretching of a liquid bridge
Liquid bridge (LB) between two surfaces creates adhesive/repulsive forces between the surfaces as per its shape. In the static condition, only capillary forces are present, but during stretching of

TLDR
A method was introduced for contact angle measurements under equilibrium conditions that enables to determine even ultralow contact angles with high precision without prewetting the investigated surface because in this case the capillary bridge of the test liquid is formed from a pendant drop and used as a probe.

Modeling liquid bridge between surfaces with contact angle hysteresis.
TLDR
The model was shown to be able to correctly predict the behavior of the liquid bridge during a quasi-static compression/stretching loading cycle in experiments, and the maximum adhesion force generated by the liquid Bridge is found to be influenced by the CAH of surfaces.

TLDR
The suggested mechanism of the contact angle hysteresis has a direct experimental confirmation: the process of receding is accompanied by the formation of thick β-films on the capillary walls, which takes place in very thin capillaries, when the receding contact angle decreases to zero.
