Weak-electrolyte diffusiophoresis for rigid colloids
Subrata Majhi, Huanshu Tan
We develop a model for the diffusiophoresis of a chemically inert, rigid spherical colloid with fixed surface charge in a monovalent weak electrolyte, in which a neutral solute rev…

Electrophoretic motion of a liquid droplet with Brinkman-screened internal hydrodynamics
Sutapa Mandal, Subrata Majhi
We develop a theory for the electrophoresis of a spherical porous liquid droplet with prescribed uniform surface charge. The exterior electrokinetics is governed by the Poisson-Ner…

Diffusiophoresis of a non-polar fluid droplet laden with soluble ionic surfactants
Subrata Majhi, Somnath Bhattacharyya
We investigate the diffusiophoresis of a non-polarizable droplet laden with soluble ionic surfactant, for which the surface charge arises from adsorption of surfactant at the fluid…
