Wetting over pre-existing liquid films

Wetting Studies of Solid and Liquid Hydrogen Isotope Films

Wetting of cholesteric liquid crystals.

We investigate theoretically the wetting properties of cholesteric liquid crystals at a planar substrate. If the properties of substrate and of the interface are such that the cholesteric layers are not distorted, the wetting properties are similar to those of a nematic liquid crystal. If, on the other hand, the anchoring conditions force the distortion of the liquid crystal layers the wetting ...

Wetting dynamics of thin liquid films and drops under Marangoni and centrifugal forces.

This paper presents an experimental study on thin liquid drops and films under the combined action of centrifugal forces due to rotation and radial Marangoni forces due to a corresponding temperature gradient. We shall examine thinning of a given liquid layer both with and without rotation and also consider the onset of the fingering instability in a completely wetting liquid drop. In many of t...

Wetting behavior of liquid He on rough Cs films: Pinning, memory effect, and micropuddles

The liquid He-cesium system is a nearly ideal one for studying wetting phenomena. However, it can show nonideal behavior such as an extreme wetting hysteresis and a memory of being in contact with liquid He. We believe that this is caused by the roughness of the Cs surface. We review the wetting characteristics of Cs surfaces produced by various methods, and we qualitatively classify Cs surface...
