Colloidal attraction induced by a temperature gradient
R. Di Leonardo, F. Ianni, G. Ruocco
Colloidal crystals are of extreme importance for applied research, such as photonic crystals technology, and for fundamental studies in statistical mechanics. Long range attractive…
Hydrodynamic Interactions in Two Dimensions
R. Di Leonardo, S. Keen, F. Ianni +3
We measure hydrodynamic interactions between colloidal particles confined in a thin sheet of fluid. The reduced dimensionality, compared to a bulk fluid, increases dramatically the…
Shear banding phenomena in a Laponite suspension
F. Ianni, R. Di Leonardo, S. Gentilini +1
Shear localization in an aqueous clay suspension of Laponite is investigated through dynamic light scattering, which provides access both to the dynamics of the system (homodyne mo…
Aging after shear rejuvenation in a soft glassy colloidal suspension: evidence for two different regimes
F. Ianni, R. Di Leonardo, S. Gentilini +1
The aging dynamics after shear rejuvenation in a glassy, charged clay suspension have been investigated through dynamic light scattering (DLS). Two different aging regimes are obse…
Aggregates relaxation in a jamming colloidal suspension after shear cessation
F. Ianni, D. Lasne, R. Sarcia +1
The reversible aggregates formation in a shear thickening, concentrated colloidal suspension is investigated through speckle visibility spectroscopy, a dynamic light scattering tec…
Aging under Shear: Structural Relaxation of a Non-Newtonian Fluid
R. Di Leonardo, F. Ianni, G. Ruocco
The influence of an applied shear field on the dynamics of an aging colloidal suspension has been investigated by the dynamic light scattering determination of the density autocorr…
