Equipe: Multiscale Mechanics of Soft Solids
A winning synergy : a biodegradable nanocomposite hydrogel for drug
Engineering an advanced material for biomedical applications requires dealing with antagonistic requirements: it must exhibit resistance to fracture AND biodegradability, remain highly hydrated AND carry hydrophobic active substances… Moreover, the creativity of chemists is...
Multiscale Mechanics of Soft Solids – Traction testing machine ElectroForce 3200 (TA instruments, previously Bose)
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,...
Multiscale Mechanics of Soft Solids – Stress-controlled rheometer Anton-Paar MR501
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...
Self-assembly of a metamaterial Structure and permeability of liquid foams in the presence of an attractive interaction between bubbles
Self-assembly of a metamaterial Structure and permeability of liquid foams in the presence of an attractive interaction between bubbles PhD Student: Jordan Seknagi Year of the defense: 2022 Funding: Team(s): Multiscale Mechanics of Soft...
Chemical Physics and Dynamics of Surfaces – Dynamics in foams near the jamming transition: a microgravity experiment
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...
Multiscale Mechanics of Softs Solids – Acoustic propagation in glasses
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...
Multiscale Mechanics of Softs Solids – Fracture of biopolymer hydrogels
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...
Multiscale Mechanics of Softs Solids – Extrusion instabilities of viscoelastic and gelable fluids
Team Permanent member: Tristan Baumberger Extrusion is an industrial shaping process by which a fluid is pushed through a hole or a capillary. A wealth of instabilities are observed, either at the inlet, the...
