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…
Drop-drop coalescence: a simple crossover function between inertial and viscous dynamics
Kaili Xie, Marie Corpart, Antoine Deblais +1
The coalescence of liquid drops is a fundamental process that remains incompletely understood, particularly in the intermediate regimes where capillary, viscous, and inertial force…
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…
Early Stages of Drop Coalescence
Antoine Deblais, Kaili Xie, Peter Lewin-Jones +5
Despite the large body of research on coalescence, firm agreement between experiment, theory, and computation has not been established for the very first moments following the init…
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…
Surface-Mediated Molecular Transport of a Lipophilic Fluorescent Probe in Polydisperse Oil-in-Water Emulsions
Marius R. Bittermann, Tatiana I. Morozova, Santiago F. Velandia +4
Emulsions often act as carriers for water-insoluble solutes that are delivered to a specific target. The molecular transport of solutes in emulsions can be facilitated by surfactan…
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…
Emulsion Destabilization by Squeeze Flow
Riande I Dekker, Antoine Deblais, Krassimir P Velikov +5
There is a large debate on the destabilization mechanism of emulsions. We present a simple technique using mechanical compression to destabilize oil-in-water emulsions. Upon compre…
Capillary Thinning of Elastic and Viscoelastic Threads: from Elastocapillarity to Phase Separation
H. V. M. Kibbelaar, A. Deblais, F. Burla +3
The formation and destabilisation of viscoelastic filaments are of importance in many industrial and biological processes. Filament instabilities have been observed for viscoelasti…
Light-switchable deposits from evaporating drops containing motile microalgae
Marius R. Bittermann, Daniel Bonn, Sander Woutersen +1
Deposits from evaporating drops have shown to take a variety of shapes, depending on the physicochemical properties of both solute and solvent. Classically, the evaporation of drop…
Phase Separation by Entanglement of Active Polymerlike Worms
A. Deblais, A. C. Maggs, D. Bonn +1
We investigate the aggregation and phase separation of thin, living T. tubifex worms that behave as active polymers. Randomly dispersed active worms spontaneously aggregate to form…
Rheology of Active Polymer-like T. Tubifex Worms
Antoine Deblais, Sander Woutersen, Daniel Bonn
Of all complex fluids, it is probably the rheology of polymers we understand best. In-depth insight into the entanglement and reptation of individual polymers allows us to predict…
