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…
Current MD forcefields fail to capture key features of protein structure and fluctuations: A case study of cyclophilin A and T4 lysozyme
Zhe Mei, Alex T. Grigas, John D. Treado +6
Globular proteins undergo thermal fluctuations in solution, while maintaining an overall well-defined folded structure. In particular, studies have shown that the core structure of…
