Molecular adsorption induces normal stresses at frictional interfaces of hydrogels
Lola Ciapa, Yvette Tran, Christian Frétigny +2
Friction experiments were conducted on hydrogel thin films sliding against a rigid sphere in a low velocity regime where molecular adsorption at the sliding interface sets the fric…
Probing interfacial effects with thermocapillary flows
M. Maza-Cuello, C. Frétigny, L. Talini
We report on the thinning of supported liquid films driven by thermocapillarity. The liquids are oil films, of initial thicknesses of a few tens of microns. A local and moderate he…
Adhesive contact of elastomers: effective adhesion energy and creep function
Etienne Barthel, Christian Frétigny
For the adhesive contact of elastomers, we propose expressions to quantify the impact of viscoelastic response on effective adhesion energy as a function of contact edge velocity.…
Surface Fluctuations of an Aging Colloidal Suspension: Evidence for Intermittent Quakes
Alexandre Mamane, Christian Frétigny, François Lequeux +1
We present measurements of the thermal fluctuations of the free surface of an aging colloidal suspension, Laponite. The technique consists in measuring the fluctuations of the posi…
