Photoconductive nonpolar liquids based on azobenzene
Carlo Rigoni, Promeet K. Saha, Jinyu Sheng +1
The weakly conductive properties of mixtures of organic surfactants in nonpolar liquids are fundamental to many electrohydrodynamic phenomena and underpin several cutting-edge tech…
Active Rosensweig Patterns
Carlo Rigoni, Max Philipp Holl, Alberto Scacchi +5
Ferrofluids, colloidal dispersions of magnetic nanoparticles, are renowned for pattern formation like few other materials. The Rosensweig instability of a horizontal ferrofluid-air…
Magnetically tunable electrokinetic instability and structuring of non-equilibrium nanoparticle gradients
Fereshteh Sohrabi, Carlo Rigoni, Tomy Cherian +2
Inspired by emergent behaviors of living matter, there is increasing interest in developing approaches to create dynamic patterns and structures in synthetic materials with control…
A Coarse-grained Model for Aqueous Two-phase Systems: Application to Ferrofluids
Alberto Scacchi, Carlo Rigoni, Mikko Haataja +2
Aqueous two-phase systems (ATPSs), that is, phase-separating solutions of water soluble but mutually immiscible molecular species, offer fascinating prospects for selective partiti…
Ferrofluidic aqueous two-phase system with ultralow interfacial tension, instabilities and pattern formation
Carlo Rigoni, Bent Harnist, Grégory Beaune +1
Ferrofluids are strongly magnetic fluids consisting of magnetic nanoparticles dispersed in a carrier fluid. Besides their technological applications, they have a tendency to form b…
Electroferrofluids with non-equilibrium voltage-controlled magnetism, interfaces, and patterns
Tomy Cherian, Fereshteh Sohrabi, Carlo Rigoni +2
Materials with continuous dissipation can exhibit responses and functionalities that are not possible in thermodynamic equilibrium. While this concept is well-known, a major challe…
