Surface instabilities generated by a slider pulled across a granular bed
Antoine Dop, Valérie Vidal, Nicolas Taberlet
We report an instability of a slider slowly dragged at the surface of a granular bed in a quasistatic regime. The boat-shaped slider sits on the granular medium under its own weigh…
Ion pairing controls rheological properties of "processionary" polyelectrolyte hydrogels
Hassan Srour, Martien Duvall Deffo Ayagou, Thi Thanh-Tam Nguyen +5
We demonstrated recently that polyelectrolytes with cationic moieties along the chain and a single anionic head are able to form physical hydrogels due to the reversible nature of…
Measurement of the acoustic radiation force on a sphere embedded in a soft solid
Pierre Lidon, Louis Villa, Nicolas Taberlet +1
The acoustic radiation force exerted on a small sphere located at the focus of an ultrasonic beam is measured in a soft gel. It is proved to evolve quadratically with the local amp…
Multiple yielding processes in a colloidal gel under large amplitude oscillatory stress
Thomas Gibaud, Christophe Perge, Stefan B. Lindstrom +2
Fatigue refers to the changes in material properties caused by repeatedly applied loads. It has been widely studied for, e.g., construction materials, but much less has been done o…
Mediating gel formation from structurally controlled poly(electrolytes) through multiple "head-to-body" electrostatic interactions
Hassan Srour, Olivier Ratel, Mathieu Leocmach +9
Tuning the chain-end functionality of a short-chain cationic homopolymer, owing to the nature of the initiator used in the ATRP polymerisation step, can be used to mediate the form…
Grains unchained: local fluidization of a granular packing by focused ultrasound
Pierre Lidon, Nicolas Taberlet, Sebastien Manneville
We report experimental results on the dynamics of a granular packing submitted to high-intensity focused ultrasound. Acoustic radiation pressure is shown to remotely induce local r…
