Magnetically powered metachronal waves induce locomotion in self-assemblies
Ylona Collard, Galien Grosjean, Nicolas Vandewalle
When tiny soft ferromagnetic particles are placed along a liquid interface and exposed to a vertical magnetic field, the balance between capillary attraction and magnetic repulsion…
Regimes of motion of magnetocapillary swimmers
Alexander Sukhov, Maxime Hubert, Galien Grosjean +6
The dynamics of a triangular magnetocapillary swimmer is studied using the lattice Boltzmann method. Performing extensive numerical simulations taking into account the coupled dyna…
Quantitatively consistent, scale-spanning model for same-material tribocharging
Galien Grosjean, Sebastian Wald, Juan Carlos Sobarzo +1
By rigorously accounting for mesoscale spatial correlations in donor/acceptor surface properties, we develop a scale-spanning model for same-material tribocharging. We find that me…
Wave turbulence on the surface of a fluid in a high-gravity environment
Annette Cazaubiel, Sébastien Mawet, Alexis Darras +4
We report on the observation of gravity-capillary wave turbulence on the surface of a fluid in a high-gravity environment. By using a large-diameter centrifuge, the effective gravi…
Magnetoelastic instability in soft thin films
M. Poty, F. Weyer, G. Grosjean +2
Ferromagnetic particles are incorporated in a thin soft elastic matrix. A lamella, made of this smart material, is studied experimentally and modeled. We show herein that thin film…
Capillary assemblies in a rotating magnetic field
Galien Grosjean, Maxime Hubert, Ylona Collard +4
Small objects floating on a fluid have a tendency to aggregate due to capillary forces. This effect has been used, with the help of a magnetic induction field, to assemble submilli…
