La migration et l’adhesion cellulaires sont deux processus essentiels intervenant dans la structuration et le developpement des tissus. Pour preciser l’influence respective des environnements biochimiques et mecaniques sur la cellule permettant c

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 distortions of a liquid meniscus do propagate along the contact line.

We have investigated the wetting behaviour of superfluid helium-4 on silicon. Surprisingly, we observe pseudo-dewetting: though a thick superfluid film covers the substrate, the meniscus diplays a finite contact angle which decreases from about 5° a

Observation of pseudo-dewetting of helium-4 on silicon is reported. This unusual behavior mimics a finite contact angle, although the substrate is wetted. This is attributed to superfluid flow in the meniscus created by heat absorption in the substra

We discuss the behaviour of 4He meniscus on various disordered Cs substrates. We have first studied the dynamics of the contact line on Cs substrates evaporated at low temperature. The activated motion of the line is consistent with a substrate disor
