Near-surface colloidal dynamics in jammed and slipping microgel suspensions
Masoodah Gunny, Frédérick Caetano, Matilde Bureau +4
Jammed suspensions of soft microgel particles may exhibit slippage along smooth boundaries. Owing to their expected sub-micrometric dimensions, direct observations of dynamics with…
Nanoparticle Taylor dispersion near charged surfaces with an open boundary
Alexandre Vilquin, Vincent Bertin, Elie Raphaël +3
The dispersive spreading of microscopic particles in shear flows is influenced both by advection and thermal motion. At the nanoscale, interactions between such particles and their…
Near-surface rheology and hydrodynamic boundary condition of semi-dilute polymer solutions
Gabriel Guyard, Alexandre Vilquin, Nicolas Sanson +2
Understanding confined flows of complex fluids requires simultaneous access to the mechanical behaviour of the liquid and the boundary condition at the interfaces. Here, we use eva…
Azimuthal instability of the radial thermocapillary flow around a hot bead trapped at the water-air interface
G. Koleski, A. Vilquin, J. -C. Loudet +2
We investigate the radial thermocapillary flow driven by a laser-heated microbead in partial wetting at the water-air interface. Particular attention is paid to the evolution of th…
Time dependence of advection-diffusion coupling for nanoparticle ensembles
Alexandre Vilquin, Vincent Bertin, Pierre Soulard +5
Advection-diffusion coupling can enhance particle and solute dispersion by orders of magnitude as compared to pure diffusion, with a steady state being reached for confined flow re…
Stokes-Einstein diffusion of colloids in nematics
Frédéric Mondiot, Jean-Christophe Loudet, Olivier Mondain-Monval +3
We report the experimental observation of anisotropic diffusion of polystyrene particles immersed in a lyotropic liquid crystal with two different anchoring conditions. Diffusion i…
