Rheology of sedimenting particle pastes
Abdoulaye Fall, Henri de Cagny, Daniel Bonn +4
We study the local and global rheology of non-Brownian suspensions in a solvent that is not density-matched, leading to either creaming or sedimentation of the particles. Both loca…
Shear thickening of cornstarch suspensions
Abdoulaye Fall, François Bertrand, Guillaume Ovarlez +1
We study the rheology of cornstarch suspensions, a non-Brownian particle system that exhibits discontinuous shear thickening. Using magnetic resonance imaging (MRI), the local prop…
Aging of rotational diffusion in colloidal gels and glasses
S. Jabbari-Farouji, G. H. Wegdam, Daniel Bonn
We study the rotational diffusion of aging Laponite suspensions for a wide range of concentrations using depolarized dynamic light scattering. The measured orientational correlatio…
Dynamical heterogeneity in aging colloidal glasses of Laponite
Sara Jabbari-Farouji, Rojman Zargar, Gerard Wegdam +1
Glasses behave as solids due to their long relaxation time; however the origin of this slow response remains a puzzle. Growing dynamic length scales due to cooperative motion of pa…
