Relevance of Aggregate Anisotropy in Sheared Suspensions of Carbon Black
Victor Tänzel, Fabian Coupette, Marisol Ripoll +1
Carbon Black is a filler frequently used in conductive suspensions or nanocomposites, in which it forms networks supporting electric conductivity. Although Carbon Black aggregates…
Obstacle-tuned transition from chaotic to coherent vortex flows and odd diffusion in chiral active fluids
Joscha Mecke, Yongxiang Gao, Marisol Ripoll
The interaction of a suspension of rotating colloids with a periodically patterned structure is here investigated by means of continuum theoretical predictions and hydrodynamic sim…
Directed Swarm Assembly due to Mixed Misaligned Perception-Dependent Motility
Rodrigo Saavedra, Marisol Ripoll
A mixture of particles with perception-dependent motility and opposite misaligned visual perception shows to spontaneously self-organize into a self-propelling bean-shaped cluster.…
Chiral active systems near a substrate: Emergent damping length controlled by fluid friction
Joscha Mecke, Yongxiang Gao, Gerhard Gompper +1
Chiral active fluids show the emergence of a turbulent behavior characterized by multiple dynamic vortices whose maximum size is specific for each experimental system. This is in c…
Swirling due to misaligned perception-dependent motility
Rodrigo Saavedra, Gerhard Gompper, Marisol Ripoll
A system of particles with motility variable in terms of a vision-type of perception is here investigated by a combination of Langevin dynamics simulations in two-dimensional syste…
Progressive polymer deformation induced by polar activity and the influence of inertia
Andrés R. Tejedor, Jorge RamÃrez, Marisol Ripoll
Polar activity is shown here to induce a progressive local deformation of linear polymer chains, making a clear distinction between head and tail, while the overall chain conformat…
