Collective alignment controls rotation frustration in granular flows of elongated particles
Antonio Pol, Riccardo Artoni, Patrick Richard
Dense granular flows made of elongated particles exhibit a strong inhibition of particle rotation compared to spherical grains, but the mechanisms responsible for this effect remai…
Granular drag and lift force on a flexible fiber
Antonio Pol, Sara Storti, Fabio Gabrieli
In this work, we investigate the forces acting on a flexible fiber dragged through a granular bed. Using discrete element simulations, we observe that, after a sufficiently large d…
Active rheology of soft solids performed with acoustical tweezers
Antoine Penneron, Thomas Brunet, Diego Baresch
Single-beam acoustical tweezers are used to manipulate individual microbubbles and provide quantitative measurements of the local shear modulus of soft hydrogels. The microbubbles…
Delicate Analysis of Interacting Proteins and Their Assemblies by Flow Field-Flow Fractionation Techniques
Aurélien Urbes, Marie-Hélène Morel, Laurence Ramos +2
We study the efficiency of several Asymmetrical Flow Field-Flow Fractionation (AF4) techniques to investigate the self-associating wheat gluten proteins. We compare the use of a de…
Evolving motility of active droplets is captured by a self-repelling random walk model
Wenjun Chen, Adrien Izzet, Ruben Zakine +3
Swimming droplets are a class of active particles whose motility changes as a function of time due to shrinkage and self-avoidance of their trail. Here we combine experiments and t…
Emergence of tip singularities in dissolution patterns
Martin Chaigne, Sabrina Carpy, Marion Massé +3
Chemical erosion, one of the two major erosion processes along with mechanical erosion, occurs when a soluble rock like salt, gypsum or limestone is dissolved in contact with a wat…
Structure and elasticity of model disordered, polydisperse and defect-free polymer networks
Valerio Sorichetti, Andrea Ninarello, José Ruiz-Franco +5
The elasticity of disordered and polydisperse polymer networks is a fundamental problem of soft matter physics that is still open. Here, we self-assemble polymer networks via simul…
Flow of gluten with tunable protein composition: from stress undershoot to stress overshoot and strain hardening
Ameur Louhichi, Marie-Helene Morel, Laurence Ramos +1
Understanding the origin of the unique rheological properties of wheat gluten, the protein fraction of wheat grain, is crucial in bread-making processes and questions scientists si…
Batch versus microfluidic emulsification processes to produce whey protein microgel beads from thermal or acidic gelation
Alban Lacroix, Murielle Hayert, Veronique Bosc +1
Producing food-grade soft particles with controlled structure is of interest to elucidate the structure-properties relationship in soft-particles suspensions. The aim of this work…
Investigating the source of hysteresis in the Soil-Water Characteristic Curve using the multiphase lattice Boltzmann method
Reihaneh Hosseini, Krishna Kumar, Jean-Yves Delenne
The soil-water characteristic curve (SWCC) is the most fundamental relationship in unsaturated soil mechanics, relating the amount of water in the soil to the corresponding matric…
Dynamics of nanoparticles in polydisperse polymer networks: From free diffusion to hopping
Valerio Sorichetti, Virginie Hugouvieux, Walter Kob
Using molecular dynamics simulations we study the static and dynamic properties of spherical nanoparticles (NPs) embedded in a disordered and polydisperse polymer network. Purely r…
A decatungstate-based Ionic liquid exhibiting very low dielectric constant suitable for acting as solvent and catalyst for oxidation of organic substrates
Yohan Martinetto, Bruce Pégot, Catherine Roch +7
In this contribution, a new POM-based ionic liquid, namely (P6,6,6,14)4[W10O32], was fully characterized. Its viscosity and its very low dielectric constant make this hybrid ionic…
Ultra-Slow Acoustic Energy Transport in Dense Fish Aggregates
Benoit Tallon, Philippe Roux, Guillaume Matte +3
A dramatic slowing down of acoustic wave transport in dense fish shoals is observed in open-sea fish cages. By employing a multi-beam ultrasonic antenna, we observe the coherent ba…
The effect of chain polydispersity on the elasticity of disordered polymer networks
Valerio Sorichetti, Andrea Ninarello, José M. Ruiz-Franco +4
Due to their unique structural and mechanical properties, randomly-crosslinked polymer networks play an important role in many different fields, ranging from cellular biology to in…

Laurence Ramos, Amélie Banc, Ameur Louhichi +6
We investigate the structure of gluten polymer-like gels in a binary mixture of water/ethanol, v/v, a good solvent for gluten proteins. Gluten comprises two main families o…
Tailoring the viscoelasticity of polymer gels of gluten proteins through solvent quality
Salvatore Costanzo, Amélie Banc, Ameur Louhichi +4
We investigate the linear viscoelasticity of polymer gels produced by the dispersion of gluten proteins in water:ethanol binary mixtures with various ethanol contents, from pure wa…
