Abstract:
Diffusion of colloidal particles in microchannels has been extensively investigated, where the channel wall is either a no-slip or a slip-passive boundary. However, in the context of active fluids, driving boundary walls are ubiquitous and are expected to have a substantial effect on the particle dynamics. By mesoscale simulations, we study the diffusion of a chemically active colloidal particle in composite channels, which are constructed by alternately arranging the no-slip and diffusio-osmotic boundary walls. In this case, the chemical reaction catalyzed by the active colloidal particle cre

Abstract:
Flow control is a highly relevant topic for micromanipulation of colloidal particles in microfluidic applications. Here, we report on a system that combines two-surface bound flows emanating from thermo-osmotic and diffusio-osmotic mechanisms. These opposing flows are generated at a gold surface immersed into an aqueous solution containing a photo-sensitive surfactant, which is irradiated by a focused UV laser beam. At low power of incoming light, diffusio-osmotic flow due to local photo-isomerization of the surfactant dominates, resulting in a flow pattern oriented away from the irradiated ar

Abstract:
We employ the moderate-Péclet-number macroscale model developed in part 2 of this sequence (Schnitzer et al., J. Fluid Mech., vol. 704, 2012, pp. 109–136) towards the calculation of electroviscous forces on charged solid particles engendered by an imposed relative motion between these particles and the electrolyte solution in which they are suspended. In particular, we are interested in the kinematic irreversibility of these forces, stemming from the diffusio-osmotic slip which accompanies the salt-concentration polarisation induced by that imposed motion. We illustrate the electroviscous irre

Abstract:
Ion exchange membranes (IEMs) are widely used in industrial sectors from batteries and energy harvesting, to water treatment and desalination. They are designed with a high selectivity and a low electrical resistance. However, the way to measure such performances independently from interpretation and device parameters (geometrical sizes, water flux, electrodes, measurement type, etc.) remains a challenge. Therefore, many performances announced in the current literature are not reliable. This study focuses on membranes prepared for reverse electro-dialysis applications, but could be generalized

Abstract:
The emergence of new nanoporous materials, based, e.g., on 2D materials, offers new avenues for water filtration and energy. There is, accordingly, a need to investigate the molecular mechanisms at the root of the advanced performances of these systems in terms of nanofluidic and ionic transport. In this work, we introduce a novel unified methodology for Non-Equilibrium classical Molecular Dynamic simulations (NEMD), allowing to apply likewise pressure, chemical potential, and voltage drops across nanoporous membranes and quantifying the resulting observables characterizing confined liquid tra

Abstract:
Pour lutter efficacement contre le réchauffement climatique, il est nécessaire d'augmenter la production d'énergies propres et renouvelables. L'énergie solaire, l'énergie éolienne, l’hydroélectrique et l'énergie marémotrice sont des technologies matures. L'augmentation de la production d'énergie renouvelable nécessite l'utilisation de sources d'énergie peu ou pas exploitées, comme l’énergie bleue. Cette forme d’énergie correspond à l’énergie générée lors du mélange d'eau douce et d'eau salée. Cependant, les procédés actuels d’extraction d'énergie à partir de gradients de sel restent inefficace
