High solid dispersions are soft materials made of colloidal or non-colloidal particles
dispersed at high volume fractions in a liquid matrix. They include hard sphere glasses …

Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays
and cementitious pastes to emulsions and physical gels encountered in food or biomedical …

The rheology of aqueous solutions of Pluronic F127 is studied as a function of concentration,
temperature, and shear rate. At sufficiently low temperatures, the solutions behave like …

This study presents the spreading of a single filament of a yield stress (viscoplastic) fluid
extruded onto a pre-wetted solid surface. The filaments spread laterally under surface …

The spreading under surface tension and gravity of a droplet of yield-stress fluid over a thin
film of the same material is studied. The droplet converges to a final equilibrium shape once …

We study the injection flow of a heavy viscoplastic fluid into a light Newtonian fluid, via
modelling and experiments. The injection is carried out downward, via an eccentric inner …

The evolution of the liquid bridge formed between two coalescing sessile yield-stress drops
is studied experimentally. Surprisingly, we find that the height of the bridge evolves similar to …

We consider experimentally the viscous fingering problem wherein a silicone oil displaces a
Carbopol gel in a rectangular Hele-Shaw cell. Unlike traditional cases, the displacing fluid …

The impact of viscoplastic droplets on a free surface of water is studied. The droplet
undergoes an elasto-plastic deformation at the early stages of water entry. At large time, the …

Wetting dynamics drive numerous processes involving liquids in contact with solid
substrates with a wide range of geometries. The spreading dynamics of organic liquids and …
