Active Reinforcement of Jammed Emulsions by Living Microswimmers
Marie Corpart, Hugo Le Roux, Daniel Bonn +1
We show that living microswimmers mechanically reinforce dense emulsions. Castor-oil-in-water emulsions laden with the microalga Chlamydomonas reinhardtii are compared in three sta…
When does the elastic regime begin in viscoelastic pinch-off?
A. Gaillard, M. A. Herrada, A. Deblais +4
In this experimental and numerical study, we revisit the question of the onset of the elastic regime in viscoelastic pinch-off. This is relevant for all modern filament thinning te…
Beware of CaBER: Filament thinning rheometry does not always give `the' relaxation time of polymer solutions
Antoine Gaillard, Miguel Angel Herrada Gutierrez, Antoine Deblais +2
The viscoelastic relaxation time of a polymer solution is often measured using Capillary Breakup Extensional Rheometry (CaBER) where a droplet is placed between two plates which ar…
Stringiness of Hyaluronic Acid Emulsions
H. V. M. Kibbelaar, A. Deblais, K. P. Velikov +2
In this work, we underline the importance of the molecular weight of hyaluronic acid on the elongational properties of concentrated emulsions. The filament formation properties, e.…
Self-similarity in the breakup of very dilute viscoelastic solutions
A. Deblais, M. A. Herrada, J. Eggers +1
When pushed out of a syringe, polymer solutions form droplets attached by long and slender cylindrical filaments whose diameter decreases exponentially with time before eventually…
Creep and drainage in the fast destabilization of emulsions Creep and drainage in the fast destabilization of emulsions
Riande I. Dekker, Antoine Deblais, Bastiaan Veltkamp +3
The destabilization of emulsions is important for many applications but remains incompletely understood. We perform squeeze flow measurements on oil-in-water emulsions, finding tha…
