Egg-speriments: Stretch, crack, and spin
Yann Bertho, Baptiste Darbois Texier, Ludovic Pauchard
Eggs are key ingredients in our kitchens because of their nutritional values and functional properties such as foaming, emulsifying and gelling, offering a wide variety of culinary…
Surface patterns in drying films of silica colloidal dispersions
François Boulogne, Frédérique Giorgiutti-Dauphiné, Ludovic Pauchard
We report an experimental study on the drying of silica colloidal dispersions. Here we focus on a surface instability occurring in a drying paste phase before crack formation which…
Structural anisotropy of directionally dried colloids
François Boulogne, Ludovic Pauchard, Frédérique Giorgiutti-Dauphiné +6
Aqueous colloidal dispersions of silica particles become anisotropic when they are dried through evaporation. This anisotropy is generated by a uniaxial strain of the liquid disper…
Suppression of the Rayleigh-Plateau instability on a vertical fibre coated with wormlike micelle solutions
François Boulogne, Marc-Antoine Fardin, Sandra Lerouge +2
We report on the Rayleigh-Plateau instability in films of giant micelles solutions coating a vertical fibre. We observe that the dynamics of thin films coating the fibre could be v…
How to reduce the crack density in drying colloidal material?
François Boulogne, Frédérique Giorgiutti-Dauphiné, Ludovic Pauchard
The drying of a colloidal dispersion can result in a gel phase defined as a porous matrix saturated in solvent. During the drying process, high mechanical stresses are generated. W…
The buckling and invagination process during consolidation of colloidal droplets
François Boulogne, Frédérique Giorgiutti-Dauphiné, Ludovic Pauchard
Drying a droplet of colloidal dispersion can result in complex pattern formation due to both development and deformation of a skin at the drop surface. The present study focus on t…
