Diffusiophoresis in complex and confined fluids
… polymers and other moieties is known as diffusiophoresis. In this thesis, we study diffusiophoresis using a combination of theory and computer simulations. We use non-equilibrium thermodynamics, starting from the entropy production to build our theoretical framework aiming to discuss some …

Diffusiophoresis and Auto Stratification in Rapidly Drying Colloidal Suspensions
… for these phenomena is believed to be diffusiophoresis, which refers to the phoretic motion of a particle driven by the concentration gradients of other solutes in the suspension. Although molecular diffusiophoresis, where salts with a molecular size much smaller than the phoretic …

Measurement of Diffusiophoresis in Liquids via a Ternary Diffusion Formulation
The phenomenon of diffusiophoresis causes a flux of micron and sub-micron sized particles as the result of the movement of some solute in solution. This phenomenon is quantified for a system of charged polystyrene latex-electrolyte-water.

INVESTIGATION OF CARBON DOTS BEHAVIOR: DIFFUSIOPHORESIS AND INFLUENCE ON THE OIL-WATER INTERFACES
Carbon dots (CDs) are promising for enhanced oil recovery, medical and environmental applications, but the successful implementation of CDs in these fields needs a comprehensive understanding of their transport behavior within solvent gradients and their influence on interfacial tension and surface …

Electrokinetic Phenomena in Colloidal Systems: Experimental and Numerical Investigations of Electrophoresis and Diffusiophoresis
… phenomena such as electrophoresis (EP) and diffusiophoresis (DP) have been widely adopted. EP involves the motion of particles or droplets under the influence of an external electric field, whereas DP refers to the spontaneous motion of colloids driven by a bulk concentration gradient of …

Colloidal phoretic motion
… numerically to model diffusion, excluded volume diffusiophoresis, hard sphere and Derjaguin–Landau–Verwey–Overbeek (DLVO) interactions in a drying film. Excluded volume diffusiophoresis is found to act to promote small-on-top stratification, causing fluxes of a similar magnitude to diffusion. The …

Chemically driven soft bioinspired systems and the variational formulation of physics-informed neural networks
… We explain this behavior by introducing gel diffusiophoresis, where interactions between the polymer and released ions drive a diffusio-osmotic solvent intake countered by diffusiophoretic motion of the polymer network, enabling the gel to swell at superdiffusive rate. We present a linear …

Hydrodynamics Of Drops And Particles Driven By Marangoni And Diffusiophoretic Forces
… between a spherical Janus motor driven by self-diffusiophoresis and an inert cargo particle is explored in an axisymmetric configuration within the Stokes regime. A stream function-based analog to the twin multipole approach is developed to study the dynamics of the motor and the cargo in …

Advances in biophysical methods for protein detection and characterisation
… coefficient of the protein can be extracted by diffusiophoresis, which is the motion of proteins driven by the concentration gradient of another solute. This could be an important protein motion mechanism, as many gradients are present in cells and in living beings. Finally, the spatial …

Dynamics of Micro-Particles in Complex Environment
… studied using numerical simulations. The self-diffusiophoresis of JCMs in a confined environment is studied first. Overall, the translocation of a JCM through a short pore is slowed down by pore walls, although the slowdown is far weaker than the transport of particles through similar pores …
