| Résumé : | Janus particles are two sided objects whose intrinsic asymmetry may be used to generate a gradient around the particles, leading to an effective propulsion. We characterize this motion in the case of a simple catalytic reaction. Mesoscopic hydrodynamical simulations (Multiparticle collision dynamics) coupled to molecular dynamics allow us to study the directed motion within a solvent. The modeling of the Janus particle as a rigid assembly of beads leads to a microscopic description that includes reactive and nonreactive collisions with the surface beads of the compound. |
