Probing the Fluctuation-Dissipation Theorem in a Perrin-like Experiment
Jean Colombani, Laure Petit, Christophe Ybert +1
In this Letter, we present a new experimental approach to investigate the effective temperature concept as a generalization of the fluctuation-dissipation theorem (FDT) for nonequi…
Filamentous phages as building blocks for reconfigurable and hierarchical self-assembly
Thomas Gibaud
Filamentous bacteriophages such as fd-like viruses are monodisperse rod-like colloids that have well defined properties: diameter, length, rigidity, charge and chirality. Engineeri…
What controls thermo-osmosis? Molecular simulations show the critical role of interfacial hydrodynamics
Li Fu, Samy Merabia, Laurent Joly
Thermo-osmotic and related thermo-phoretic phenomena can be found in many situations from biology to colloid science, but the underlying molecular mechanisms remain largely unexplo…
Nonlinear focusing in dynamic crack fronts and the micro-branching transition
Itamar Kolvin, Jay Fineberg, Mokhtar Adda-Bedia
Cracks in brittle materials produce two types of generic surface structures: facets at low velocities and micro-branches at higher ones. Here we observe a transition from faceting…
Non-wetting drops at liquid interfaces: From liquid marbles to Leidenfrost drops
Clint Y. H. Wong, Mokhtar Adda-Bedia, Dominic Vella
We consider the flotation of deformable, non-wetting drops on a liquid interface. We consider the deflection of both the liquid interface and the droplet itself in response to the…
Forced imbibition in porous media: a fourfold scenario
Céleste Odier, Bertrand Levaché, Enrich Santanach-Carreras +1
We establish a comprehensive description of the patterns formed when a wetting liquid displaces a viscous fluid confined in a porous medium. Building on model microfluidic experime…
