Scaling Properties of Gelling Systems in Nonlinear Shear Experiments
Ameur Louhichi, Marie-Hélène Morel, Laurence Ramos +1
We study model near-critical polymer gelling systems made of gluten proteins dispersions stabilized at different distances from the gel point. We impose different shear rates and f…
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…
Instabilities in freely expanding sheets of associating viscoelastic fluids
S. Arora, A. Louhichi, D. Vlassopoulos +2
We use the impact of drops on a small solid target as a tool to investigate the behavior of viscoelastic fluids under extreme deformation rates. We study two classes of transient n…
Competition between shear and biaxial extensional viscous dissipation in the expansion dynamics of Newtonian and rheo-thinning liquid sheets
Ameur Louhichi, Carole-Ann Charles, Srishti Arora +4
When a drop of fluid hits a small solid target of comparable size, it expands radially until reaching a maximum diameter and subsequently recedes. In this work, we show that the ex…
Viscoelasticity and elastocapillarity effects in the impact of drops on a repellent surface
Carole-Ann Charles, Ameur Louhichi, Laurence ramos +1
We investigate freely expanding viscoelastic sheets. The sheets are produced by the impact of drops on a quartz plate covered with a thin layer of liquid nitrogen that suppresses s…
Impact of the protein composition on the structure and viscoelasticity of polymer-like gluten gels
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…
Biaxial extensional viscous dissipation in sheets expansion formed by impact of drops of Newtonian and non-Newtonian fluids
Ameur Louhichi, Carole-Ann Charles, Ty Phou +3
We investigate freely expanding liquid sheets made of either simple Newtonian fluids or solutions of high molecular water-soluble polymer chains. A sheet is produced by the impact…
Viscoelasticity of colloidal polycrystals doped with impurities
Ameur Louhichi, Elisa Tamborini, Julian Oberdisse +2
We investigate how the microstructure of a colloidal polycrystal influences its linear viscoelasticity. We use thermosensitive copolymer micelles that arrange in water in a cubic c…
Nucleation and growth of micellar polycrystals under time-dependent volume fraction conditions
A. Louhichi, E. Tamborini, N. Ghofraniha +5
We study the freezing kinetics of colloidal polycrystals made of micelles of Pluronic F108, a thermosensitive copolymer, to which a small amount of silica nanoparticles of size com…
