Colloidal diffusiophoresis in crossed electrolyte gradients: experimental demonstration of an 'action at a distance' effect predicted by the Nernst-Planck equations
Ian Williams, Patrick B. Warren, Richard P. Sear +1
In an externally imposed electrolyte (salt) concentration gradient, charged colloids drift at speeds of order one micrometre per second. This phenomenon is known as diffusiophoresi…
Controlling the crystal polymorph by exploiting the time dependence of nucleation rates
Laurie J. Little, Alice A. K. King, Richard P. Sear +1
Most substances can crystallise into two or more different crystal lattices, called polymorphs. Despite this, there are no systems in which we can quantitatively predict the probab…
Dynamic stratification in drying films of colloidal mixtures
Andrea Fortini, Ignacio Martín-Fabiani, Jennifer Lesage De La Haye +6
In simulations and experiments, we study the drying of films containing mixtures of large and small colloidal particles in water. During drying, the mixture stratifies into a layer…
