General approach for partitioning and phase separation in macromolecular coexisting phases
Vikki Anand Varma, Alberto Scacchi
Partitioning of (bio)materials in polymeric mixtures is a key phenomenon both in cellular environments, as well as in industrial applications. In cells, several macromolecules are…
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…
Adsorption of polyelectrolytes in the presence of varying dielectric discontinuity between solution and substrate
Hossein Vahid, Alberto Scacchi, Maria Sammalkorpi +1
We examine the interactions between polyelectrolytes (PEs) and uncharged substrates at conditions corresponding to a dielectric discontinuity between the aqueous solution and the s…
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…
Non-monotonic electrophoretic mobility of rod-like polyelectrolytes by multivalent coions in added salt
Hossein Vahid, Alberto Scacchi, Maria Sammalkorpi +1
It is well established that when multivalent counterions or salts are added to a solution of highly-charged polyelectrolytes (PEs), correlation effects can cause charge inversion o…
Self-assembly of binary solutions to complex structures
Alberto Scacchi, Maria Sammalkorpi, Tapio Ala-Nissila
Self-assembly in natural and synthetic molecular systems can create complex aggregates or materials whose properties and functionality rises from their internal structure and molec…
