Quantitative imaging of colloidal flows
Lucio Isa, Rut Besseling, Eric R. Weeks +1
We present recent advances in the instrumentation and analysis methods for quantitative imaging of concentrated colloidal suspensions under flow. After a brief review of colloidal…
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…
Velocity oscillations in confined channel flows of concentrated colloidal suspensions
Lucio Isa, Rut Besseling, Alexander N. Morozov +1
We study the pressure-driven flow of concentrated colloids confined in glass micro-channels at the single particle level using fast confocal microscopy. For channel to particle siz…
Shear zones and wall slip in the capillary flow of concentrated colloidal suspensions
Lucio Isa, Rut Besseling, Wilson C K Poon
We image the flow of a nearly random close packed, hard-sphere colloidal suspension (a `paste') in a square capillary using confocal microscopy. The flow consists of a `plug' in th…
Three-dimensional imaging of colloidal glasses under steady shear
R. Besseling, Eric R. Weeks, A. B. Schofield +1
Using fast confocal microscopy we image the three-dimensional dynamics of particles in a yielded hard-sphere colloidal glass under steady shear. The structural relaxation, observed…
Depinning and dynamics of vortices confined in mesoscopic flow channels
R. Besseling, P. H. Kes, T. Droese +1
We study the behavior of vortex matter in artificial flow channels confined by pinned vortices in the channel edges (CE's). The critical current is governed by the interactio…
