We study a situation where the complete wetting of a dielectric solid by a dielectric liquid, in
a conducting surrounding, is altered by the application of an electrical potential difference …

Wetting transitions have been predicted and observed to occur for various combinations of
fluids and surfaces. This paper describes the origin of such transitions, for liquid films on …

We explore experimentally the fluidization of vertically agitated polymethylmethacrylate
spheres wetted by liquid He 4. By controlling the temperature around the λ point, we change …

We have used high-speed video and interferometry to investigate the impact, spreading, and
eventual contraction of superfluid He 4 drops on a sapphire substrate in a saturated …

We present the resugts of an experiment on the wetting of liquid hydrogen on a cesium
substrate using helium as a surfactant. In contrast to the previously studied case of 3 He-4 …

We have studied the dynamics of a superfluid helium-4 meniscus on a solid substrate. In a
pseudo–non-wetting situation, there is no hysteresis of the contact angle. We show that …
