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 …

The review presents current research results for Carbopol-based microgels as yield-stress
materials, covering three aspects: chemical, physical and rheological. Such a joint three …

We report on the interplay between creep and residual stresses in a carbopol microgel.
When a constant shear stress σ is applied below the yield stress σ y, the strain is shown to …

We explore how different types of solvent influence the rheological properties of non-
aqueous Carbopol dispersions from the dilute to the jammed state. In novel non-aqueous …

We have studied the flow of Carbopol, a polymer microgel, confined to approximately square
microchannels with widths ranging from 451 µm down to 54 µm. Velocity profiles in the …

We present an experimental study of the rheology and structure of a confined suspension of
deformable particles flowing in a quasi-two-dimensional Poiseuille flow. Thanks to a precise …

The simple shear flow of Herschel-Bulkley fluids is analyzed, under the assumption that wall
slip occurs at both plates above a characteristic wall shear stress, the slip yield stress. The …

We explore the impact of geometrical corrugations on the near-wall flow properties of a soft
material driven in a confined rough microchannel. By means of numerical simulations, we …

Acacia gum (Gum Arabic; GA) and chitosan (CTS) form complex coacervates in acidic
environments, providing a polymer-rich aqueous material with interesting bio-lubricant …

Slip is an important phenomenon that occurs during the flow of yield stress fluids like soft
materials and pastes. Densely packed suspensions of hydrogel microparticles are used to …
