Shear-thickening induced by Faraday waves in dilute wormlike micelles
P. Ballesta, S. Manneville
We investigate the effect of surface waves generated by the Faraday instability on a shear-thickening surfactant solution under vertical vibrations. We show that a prolonged oscill…
Superposition rheology of shear-banding wormlike micelles
P. Ballesta, M. P. Lettinga, S. Manneville
Wormlike micelle solutions are submitted to small-amplitude oscillatory shear superimposed to steady shear in the shear banding regime. By imposing a shear oscillation, the interfa…
Unexpected drop of dynamical heterogeneities in colloidal suspensions approaching the jamming transition
Pierre Ballesta, Agnes Duri, Luca Cipelletti
As the glass (in molecular fluids\cite{Donth}) or the jamming (in colloids and grains\cite{LiuNature1998}) transitions are approached, the dynamics slow down dramatically with no m…
Slip and flow of hard-sphere colloidal glasses
P. Ballesta, R. Besseling, L. Isa +2
We study the flow of concentrated hard-sphere colloidal suspensions along smooth, non-stick walls using cone-plate rheometry and simultaneous confocal microscopy. In the glass regi…
Fluctations and noise in time-resolved light scattering experiments : measuring temporally heterogeneous dynamics
Agnes Duri, Pierre Ballesta, Luca Cipelletti +2
We use Time Resolved Correlation (TRC), a recently introduced light scattering method, to study the dynamics of a variety of jammed, or glassy, soft materials. The output of a TRC…
Signature of elasticity in the Faraday instability
Pierre Ballesta, Sebastien Manneville
We investigate the onset of the Faraday instability in a vertically vibrated wormlike micelle solution. In this strongly viscoelastic fluid, the critical acceleration and wavenumbe…
