Colloquium: Phase transitions in polymers and liquids in electric fields

Y Tsori - Reviews of Modern Physics, 2009 - APS
The structure and thermodynamic state of a system changes under the influence of external
electric fields. Neutral systems are characterized by their dielectric constant ε, while charged …

Phase transitions in soft matter induced by selective solvation

A Onuki, R Okamoto, T Araki - Bulletin of the Chemical Society of …, 2011 - academic.oup.com
We review our recent studies on selective solvation effects in phase separation in polar
binary mixtures with a small amount of solutes. Such hydrophilic or hydrophobic particles …

Charged colloids in an aqueous mixture with a salt

R Okamoto, A Onuki - Physical Review E—Statistical, Nonlinear, and Soft …, 2011 - APS
We calculate the ion and composition distributions around colloid particles in an aqueous
mixture, accounting for preferential adsorption, electrostatic interaction, selective solvation …

Analysis of improved Lattice Boltzmann phase field method for soluble surfactants

RGM van der Sman, MBJ Meinders - Computer Physics Communications, 2016 - Elsevier
In this paper we present a novel Lattice Boltzmann model for immiscible fluids with soluble
surfactants adsorbing at the interface with improved numerical and extended physical …

Mesoscopic electrohydrodynamic simulations of binary colloidal suspensions

N Rivas, S Frijters, I Pagonabarraga… - The Journal of chemical …, 2018 - pubs.aip.org
A model is presented for the solution of electrokinetic phenomena of colloidal suspensions
in fluid mixtures. We solve the discrete Boltzmann equation with a Bhatnagar-Gross-Krook …

Precipitation in aqueous mixtures with addition of a strongly hydrophilic or hydrophobic solute

R Okamoto, A Onuki - Physical Review E—Statistical, Nonlinear, and Soft …, 2010 - APS
We examine phase separation in aqueous mixtures due to preferential solvation with a low-
density solute (hydrophilic ions or hydrophobic particles). For hydrophilic ions, preferential …

Selective solvation effects in phase separation in aqueous mixtures

A Onuki, R Okamoto - Current opinion in colloid & interface science, 2011 - Elsevier
Selective solvation can be crucial in phase separation in polar binary mixtures (water–oil)
with a small amount of hydrophilic ions or hydrophobic particles. They are preferentially …

Solvation effects in phase transitions in soft matter

A Onuki, T Araki, R Okamoto - Journal of Physics: Condensed …, 2011 - iopscience.iop.org
Phase transitions in polar binary mixtures can be drastically altered by even a small amount
of salt. This is because the preferential solvation strongly depends on the ambient …

Stability of binary mixtures in electric field gradients

S Samin, Y Tsori - The Journal of chemical physics, 2009 - pubs.aip.org
We consider the influence of electric field gradients on the phase behavior of nonpolar
binary mixtures. Small fields give rise to smooth composition profiles, whereas large enough …

Hydrodynamic simulations of charge-regulation effects in colloidal suspensions

K Takae, H Tanaka - Soft matter, 2018 - pubs.rsc.org
Self-organization of charged soft matter is of crucial importance in biology. However, it is an
extremely complex phenomenon due to dynamical couplings between the hydrodynamic …
