Adhesion-induced fingering instabilities in thin elastic films under strain
Benjamin Davis-Purcell, Pierre Soulard, Thomas Salez +2
In this study, thin elastic films supported on a rigid substrate are brought into contact with a spherical glass indenter. Upon contact, adhesive fingers emerge at the periphery of…
Stresses in non-equilibrium fluids: Exact formulation and coarse grained theory
M. Krüger, A. Solon, V. Démery +2
Starting from the stochastic equation for the density operator, we formulate the exact (instantaneous) stress tensor for interacting Brownian particles, whose average value agrees…
Colloidal particle adsorption at water/water interfaces with ultra-low interfacial tension
Louis Keal, Carlos E. Colosqui, Hans Tromp +1
Using fluorescence microscopy we study the adsorption of single latex microparticles at a water/water interface between demixing aqueous solutions of polymers, generally known as a…
Liquid dewetting under a thin elastic film
Rafael D. Schulman, John F. Niven, Michiel A. Hack +2
We study the dewetting of liquid films capped by a thin elastomeric layer. When the tension in the elastomer is isotropic, circular holes grow at a rate which decreases with increa…
Roughness of oxide glass subcritical fracture surfaces
Gael Pallares, Frederic Lechenault, Matthieu George +4
An original setup combining a very stable loading stage, an atomic force microscope and an environmental chamber, allows to obtain very stable sub-critical fracture propagation in…
Optimizing Hyperuniformity in Self-Assembled Bidisperse Emulsions
Joshua Ricouvier, Romain Pierrat, Rémi Carminati +2
We study long range density fluctuations (hyperuniformity) in two-dimensional jammed packings of bidisperse droplets. Taking advantage of microfluidics, we systematically span a la…
