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…
Theoretical and computational analysis of the electrophoretic polymer mobility inversion induced by charge correlations
Xiang Yang, Sahin Buyukdagli, Alberto Scacchi +2
Electrophoretic (EP) mobility reversal is commonly observed for strongly charged macromolecules in multivalent salt solutions. This curious effect takes place, e.g., when a charged…
Interactions between polyelectrolytes mediated by ordering and orientation of multivalent non-spherical ions in salt solutions
Hossein Vahid, Alberto Scacchi, Maria Sammalkorpi +1
Multivalent ions in solutions with polyelectrolytes (PE) induce electrostatic correlations that can drastically change ion distributions around the PEs and their mutual interaction…
Interaction between two polyelectrolytes in monovalent aqueous salt solutions
Xiang Yang, Alberto Scacchi, Hossein Vahid +2
We use the recently developed soft-potential-enhanced Poisson-Boltzmann (SPB) theory to study the interaction between two parallel polyelectrolytes (PEs) in monovalent ionic soluti…
Modified Poisson-Boltzmann theory for polyelectrolytes in monovalent salt solutions with finite-size ions
Hossein Vahid, Alberto Scacchi, Xiang Yang +2
We present a soft-potential-enhanced Poisson-Boltzmann (SPB) theory to efficiently capture ion distributions and electrostatic potential around rodlike charged macromolecules. The…
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…
Self-assembly in soft matter with multiple length scales
Alberto Scacchi, Sousa Javan Nikkhah, Maria Sammalkorpi +1
Spontaneous self-assembly in molecular systems is a fundamental route to both biological and engineered soft matter. Simple micellisation, emulsion formation, and polymer mixing pr…
Flow induced crystallization of penetrable particles
Alberto Scacchi, Joseph M. Brader
For a system of Brownian particles interacting via a soft exponential potential we investigate the interaction between equilibrium crystallization and spatially varying shear flow.…
