The transport of suspensions of microparticles in confined environments is associated with
complex phenomena at the interface of fluid mechanics and soft matter. Indeed, the …

Earth's surface is composed of a staggering diversity of particulate–fluid mixtures: dry to wet,
dilute to dense, colloidal to granular and attractive to repulsive particles. This material variety …

We report on a microfluidic method that allows measurement of a small concentration of
large contaminants in suspensions of solid micrometer-scale particles. To perform the …

We review the experimental synthesis of smooth and rough particles, characterization of
surface roughness, quantification of the pairwise and bulk friction coefficients, and their …

The accumulation of colloidal particles to build dense structures from dilute suspensions
may follow distinct routes. The mechanical, structural and geometrical properties of these …

When a colloidal suspension flows in a constriction, particles deposit and are able to clog it
entirely, this fouling process being followed by the accumulation of particles. The knowledge …

Piles of perfectly smooth spherical particles are able to sustain a non-zero angle of repose
as a result of geometrical constraints. Here we report on a study of piles made of soft …

We investigate the growth of aggregates made of adhesive frictionless oil droplets, piling up
against a solid interface. Monodisperse droplets are produced one by one in an aqueous …

When sand flows out of a funnel onto a surface, a three dimensional pile that is stabilized by
friction grows taller as it spreads. Here we investigate an idealized two dimensional …

Thermal fluctuations, geometric exclusion, and external driving all govern the mechanical
response of dense particulate suspensions. Here, we measure the stress-strain response of …
