International audience; We examine the time-dependent distortion of a nearly circular viscous domain in an infinite viscous sheet when suction occurs. Suction, the driving force of the instability, can occur everywhere in the two phases separated by

The growth dynamics of an air finger injected in a visco-elastic gel (a PVA/borax aqueous solution) is studied in a linear Hele-Shaw cell. Besides the standard Saffmann-Taylor instability, we observe - with increasing finger velocities - the existenc

Effect of Ethanol on the Structure and Properties of β-Casein Adsorption Layers at the Air/Buffer Interface

Autor: N. Puff, Roger Douillard, Alain Cagna, Véronique Aguié-Béghin

Journal of Colloid and Interface Science, Elsevier, 1998, 208 (2), pp.405-414. ⟨10.1006/jcis.1998.5846⟩

The adsorption of beta-casein at the air-solution interface has been monitored in equilibrium conditions by neutron reflectivity. It was observed that for a bulk concentration of 100 mg/L, the amount of protein adsorbed per unit surface increases fro
