Convective Instability Driven by Diffusiophoresis of Colloids in Binary Liquid Mixtures
Carmine Anzivino, Klejdis Xhani, Marina Carpineti +3
In a binary fluid mixture, the concentration gradient of a heavier molecular solute leads to a diffusive flux of solvent and solute to achieve thermodynamic equilibrium. If the sol…
Levitation, oscillations, and wave propagation in a stratified fluid
Marina Carpineti, Fabrizio Croccolo, Alberto Vailati
We present an engaging levitation experiment that students can perform at home or in a simple laboratory using everyday objects. A cork, modified to be slightly denser than water,…
Optimal leap angle of legged and legless insects in a landscape of uniformly-distributed random obstacles
Fabio Giavazzi, Samuele Spini, Marina Carpineti +1
We investigate theoretically the ballistic motion of small legged insects and legless larvae after a jump. Notwithstanding their completely different morphologies and jumping strat…
Equilibrium and non-equilibrium concentration fluctuations in a critical binary mixture
Fabio Giavazzi, Alessandro Fornasieri, Alberto Vailati +1
When a macroscopic concentration gradient is present across a binary mixture, long-ranged non-equilibrium concentration fluctuations (NCF) appear as a consequence of the coupling b…
Dynamic scaling for the growth of non-equilibrium fluctuations during thermophoretic diffusion in microgravity
Roberto Cerbino, Yifei Sun, Aleksandar Donev +1
Diffusion processes are widespread in biological and chemical systems, where they play a fundamental role in the exchange of substances at the cellular level and in determining the…
Geometry for a `penguin-albatross' rookery
Fabio Giavazzi, Alberto Vailati
We introduce a simple ecological model describing the spatial organization of two interacting populations whose individuals are indifferent to conspecifics and avoid the proximity…
