  Traction/compression machine ioperating in mode AC, DC or AC+DC thanks to the combibation of an electromagnetic transducer (loudspeaker) and a large stroke (200 mm) linear translation stage. Working vertically as well as horizontally,...

In its native, open loop mode, a torque ranging between 0.01 µN.m and 300 mN.m is applied to the rotor whilethe angular velocity is measured. A feed-back loop enables shear-rate controlled operations. Thanks to...

Team Permanents members: Sylvie Cohen-Addad, Reinhard Höhler In microgravity, isolated gas bubbles in a liquid are spheres. Dilute dispersions of them behave as liquids. When the volume liquid fraction exceeds a critical value called...

Team Permanent member: Reinhard Hölher PhD Student: Jordan Seknagi Bubbles or monodisperse droplets suspended in water spontaneously self-organize into crystalline structures. face-centered cubic or body-centered cubic, depending on the liquid fraction. The solidification of these...

Team Permanent member : Sylvie Cohen-Addad Liquid foams (such as aqueous foams or concentrated emulsions) are made of dense packings of soft particles (gas bubbles or droplets) in a (immiscible) liquid. They are used...

Team Honorary research fellow: Christiane Caroli In glasses, acoustic propagation presents  generic features thought to be  characteristic of topological structural disorder. Up to now, theoretical approaches to this question – fluctuating elasticity (FE) theories...

Team Permanent member: Olivier Ronsin   Hydrogels, composed essentially of solvent, are soft elastic materials in which the propagation of a fracture requireslarge deformations: the crack head is very blunt. It is therefore particularly...
