Scaling regimes of active turbulence with external dissipation
Berta Martínez-Prat, Ricard Alert, Fanlong Meng +5
Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experime…
Propulsion and energetics of a minimal magnetic microswimmer
Carles Calero, José García-Torres, Antonio Ortiz-Ambriz +3
In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled…
Coexistence of nonequilibrium phases in assemblies of driven nematic colloids
Josep M. Pagès, Arthur V. Straube, Pietro Tierno +2
We combine experiments, theory, and simulations to investigate the coexistence of nonequilibrium phases emerging from interacting colloidal particles that are electrokinetically pr…
Reconfigurable swarms of colloidal particles electrophoretically drivenin nematic liquid crystals
Sergi Hernàndez-Navarro, Pietro Tierno, Jordi Ignés-Mullol +1
We present experiments where anisometric colloidal microparticles dispersed in a nematic liquid crystal cell with homeotropic anchoring conditions are dynamically assembled by mean…
Assessing the significance of knockout cascades in metabolic networks
Oriol Güell, Francesc Sagués, Georg Basler +2
Complex networks have been shown to be robust against random structural perturbations, but vulnerable against targeted attacks. Robustness analysis usually simulates the removal of…
