Self-propulsion mechanism of active Janus particles in near-critical binary mixtures

S Samin, R Van Roij - Physical review letters, 2015 - APS
Gold-capped Janus particles immersed in a near-critical binary mixture can be propelled
using illumination. We employ a nonisothermal diffuse interface approach to investigate the …

Preferential adsorption in a near-critical binary fluid mixture as analyzed in the framework of the non-random two-liquid model

Y Fujitani - Fluid Phase Equilibria, 2024 - Elsevier
We consider a binary fluid mixture, which lies in the one-phase region near the demixing
critical point. Short-range interactions between the mixture components and a solid surface …

Effects of the preferential adsorption in a near-critical binary fluid mixture on dynamics of a droplet

Y Fujitani - Physics of Fluids, 2022 - pubs.aip.org
ABSTRACT A large amount of binary fluid mixture in the homogeneous phase near the
demixing critical point can include a small spherical droplet of a third fluid-component …

Diffusiophoresis in a near-critical binary fluid mixture

Y Fujitani - Physics of Fluids, 2022 - pubs.aip.org
We consider placing a rigid spherical particle into a binary fluid mixture in the homogeneous
phase near the demixing critical point. The particle surface is assumed to have a short-range …

Isothermal transport of a near-critical binary fluid mixture through a capillary tube with the preferential adsorption

S Yabunaka, Y Fujitani - Physics of Fluids, 2022 - pubs.aip.org
We study isothermal transport of a binary fluid mixture, which lies in the homogeneous
phase near the demixing critical point, through a capillary tube. A short-range interaction is …

Fluctuation amplitude of a trapped rigid sphere immersed in a near-critical binary fluid mixture within the regime of the Gaussian model

Y Fujitani - Journal of the Physical Society of Japan, 2016 - journals.jps.jp
The position of a colloidal particle trapped in an external field thermally fluctuates at
equilibrium. As is well known, the ambient fluid is not a simple heat bath and the particle …

Structured solvent effects on precipitation: Microscopically organized cerium oxalate particles

M Jehannin, S Charton, B Corso, H Möhwald… - Colloid and Polymer …, 2017 - Springer
The synthesis of cerium oxalate, a reaction intermediate in the preparation of high
performance ceramics, is studied in sessile droplets. We compare here the effect of alcoholic …

Undulation amplitude of a fluid membrane in a near-critical binary fluid mixture calculated beyond the Gaussian model supposing weak preferential attraction

Y Fujitani - Journal of the Physical Society of Japan, 2017 - journals.jps.jp
We calculate the mean square amplitude of the shape fluctuation—an equal-time correlation—
of an almost planar fluid membrane immersed in a near-critical binary fluid mixture. One fluid …

Liquid bridging of cylindrical colloids in near-critical solvents

M Labbé-Laurent, AD Law, S Dietrich - The Journal of Chemical …, 2017 - pubs.aip.org
Within mean field theory, we investigate the bridging transition between a pair of parallel
cylindrical colloids immersed in a binary liquid mixture as a solvent that is close to its critical …

Colloidal suspensions in one-phase mixed solvents under shear flow

A Barbot, T Araki - Soft matter, 2017 - pubs.rsc.org
We numerically studied the behaviour of colloidal suspensions in one-phase binary liquid
mixtures under shear flows. Far from the phase-separation point, the colloidal particles are …
