Solitary waves and their stability in colloidal media: semi-analytical solutions
colloid solitary wave modulation theory stability bifurcation
2012/4/20
Spatial solitary waves in colloidal suspensions of spherical dielectric nanoparticles are considered. The interaction of the nanoparticles is modelled as a hard-sphere gas, with the Carnahan-Starling ...
Dynamic clustering in active colloidal suspensions with chemical signaling
Dynamic cluster active colloidal suspensions chemical signaling
2012/2/29
In this paper, we explore experimentally the phase behavior of a dense active suspension of self- propelled colloids. In addition to a solid-like and a gas-like phase observed for high and low densiti...
Anisotropic elasticity in confocal studies of colloidal crystals
vibrational states colloidal crystals
2011/9/9
We consider the theory of uctuations of a colloidal solid observed in a confocal slice. For a cubic crystal we study the evolution of the projected elastic properties as a function of the anisotropy ...
Asymptotic analysis of stresses near a crack tip in a two dimensional colloidal packing saturated with liquid
Asymptotic analysis of stresses two dimensional colloidal
2010/11/24
The consolidation of colloidal particles in drying colloidal dispersions is in-uenced by various factors such as particle size and shape, and inter-particle potential. The capillary pressure induced b...
Aging of a Homogeneously Quenched Colloidal Glass-forming Liquid
Aging Homogeneously Quenched Colloidal Glass-forming Liquid
2010/11/24
The non-equilibrium self-consistent generalized Langevin equation theory of colloid dynamics
is used to describe the non-stationary aging processes occurring in a suddenly quenched model

2010/11/18
We study the designing principles of the simplest colloidal propeller, an architecture built from four identical spheres that can couple translation with rotation to produce controlled drift motion.By...
Measuring Colloidal Forces from Particle Position Deviations inside an Optical Trap
Measuring Colloidal Forces Particle Position Deviations
2010/11/17
We present a method to measure interaction forces between pairs of charged colloidal particles
suspended in a relatively low-polar medium (5 . " . 8) directly from the deviations of particle
positio...
Colloidal particles in liquid crystal films and at interfaces
colloids confinement interfaces elastic theory computer simulations
2010/11/18
This mini-review discusses the recent contribution of theoretical and computational physics as well as experimental efforts to the understanding of the behavior of colloidal particles in confined geom...
The renormalized Jellium model of colloidal suspensions with multivalent counterions
renormalized Jellium model multivalent counterions
2010/11/22
An extension of the renormalized Jellium model which allows to study colloidal suspensions containing trivalent counterions is proposed. The theory is based on a modified Poisson-Boltzmann equation wh...
Mobility and Diffusion of a Tagged Particle in a Driven Colloidal Suspension
Mobility Diffusion Driven Colloidal Suspension
2010/11/23
We study numerically the in uence of density and strain rate on the di usion and mobility of a single tagged particle in a sheared colloidal suspension. We determine independently the time-dependent v...

Particle-scale structure frozen colloidal suspensions small angle x-ray scattering
2010/11/19
During directional solidification of the solvent in a colloidal suspension, the colloidal particles segregate from the growing solid, forming high-particle-density regions with structure on a hierarch...
