Diffusiophoresis: from dilute to concentrated electrolytes
Ankur Gupta, Suin Shim, Howard A. Stone
Abstract
The underappreciated effect of ion concentration on diffusiophoretic mobility is investigated, both theoretically and experimentally. It is demonstrated that diffusiophoretic mobility possesses a maximum with ion concentration.
