Electro-osmotic diode based on colloidal nano-valves between double membranes
Shihori Koyama, Daisuke Inoue, Akihisa Okada +1
The rectification of electro-osmotic flows is important in micro/nano fluidics applications such as micro-pumps and energy conversion devices. Here, we propose a simple electro-osm…
Numerical simulation method for Brownian particles dispersed in incompressible fluids
Hiroaki Yoshida, Tomoyuki Kinjo, Hitoshi Washizu
We present a numerical scheme for simulating the dynamics of Brownian particles suspended in a fluid. The motion of the particles is tracked by the Langevin equation, whereas the h…
Studying polymer diffusiophoresis with Non-Equilibrium Molecular Dynamics
Simón Ramírez-Hinestrosa, Hiroaki Yoshida, Lydéric Bocquet +1
We report a numerical study of the diffusiophoresis of short polymers using non-equilibrium molecular dynamics simulations. More precisely, we consider polymer chains in a fluid co…
Osmotic and diffusio-osmotic flow generation at high solute concentration. I. Mechanical approaches
Sophie Marbach, Hiroaki Yoshida, Lydéric Bocquet
In this paper, we explore various forms of osmotic transport in the regime of high solute concentration. We consider both the osmosis across membranes and diffusio-osmosis at solid…
Osmotic and diffusio-osmotic flow generation at high solute concentration. II. Molecular dynamics simulations
Hiroaki Yoshida, Sophie Marbach, Lydéric Bocquet
In this paper, we explore osmotic transport by means of molecular dynamics (MD) simulations. We first consider osmosis through a membrane, and investigate the reflection coefficien…
Carbon membranes for efficient water-ethanol separation
Simon Gravelle, Hiroaki Yoshida, Laurent Joly +2
We demonstrate, on the basis of molecular dynamics simulations, the possibility of an efficient water-ethanol separation using nanoporous carbon membranes, namely carbon nanotube m…
Labyrinthine water flow across multilayer graphene-based membranes: molecular dynamics versus continuum predictions
Hiroaki Yoshida, Lydéric Bocquet
In this paper we investigate the hydrodynamic permeance of water through graphene-based membranes, inspired by recent experimental findings on graphene-oxide membranes. We consider…
Analysis of electro-osmotic flow in a microchannel with undulated surfaces
Hiroaki Yoshida, Tomoyuki Kinjo, Hitoshi Washizu
The electro-osmotic flow through a channel between two undulated surfaces induced by an external electric field is investigated. The gap of the channel is very small and comparable…
Generic transport coefficients of a confined electrolyte solution
Hiroaki Yoshida, Hideyuki Mizuno, Tomoyuki Kinjo +2
Physical parameters characterising electrokinetic transport in a confined electrolyte solution are reconstructed from the generic transport coefficients obtained within the classic…
Molecular dynamics simulation of electrokinetic flow of an aqueous electrolyte solution in nanochannels
Hiroaki Yoshida, Hideyuki Mizuno, Tomoyuki Kinjo +2
Electrokinetic flows of an aqueous NaCl solution in nanochannels with negatively charged surfaces are studied using molecular dynamics (MD) simulations. The four transport coeffici…
