Fractional hopping-type motion in columnar mesophase of semi-flexible rod-like particles
Saber Naderi, Emilie Pouget, Pierre Ballesta +3
We report on single-particle dynamics of strongly interacting filamentous fd virus particles in the liquid-crystalline columnar state in aqueous solution. From fluorescence microsc…
Wall slip and flow of concentrated hard-sphere colloidal suspensions
P. Ballesta, G. Petekidis, L. Isa +2
We present a comprehensive study of the slip and flow of concentrated colloidal suspensions using cone-plate rheometry and simultaneous confocal imaging. In the colloidal glass reg…
Interplay between a hydrodynamic instability and a phase transition: the Faraday instability in dispersions of rodlike colloids
Pierre Ballesta, M. Paul Lettinga, Sebastien Manneville
Strong effects of the Faraday instability on suspensions of rodlike colloidal particles are reported through measurements of the critical acceleration and of the surface wave ampli…
Shear banding and flow-concentration coupling in colloidal glasses
R. Besseling, L. Isa, P. Ballesta +3
We report experiments on hard sphere colloidal glasses that reveal a type of shear banding hitherto unobserved in soft glasses. We present a scenario that relates this to an instab…
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…
The Faraday instability in wormlike micelle solutions
P. Ballesta, S. Manneville
The behaviour of semi-dilute wormlike micelle solutions under vertical vibrations is investigated using classical measurements of the Faraday instability threshold along with two n…
