Electric double layers in- and out-of-equilibrium

The electric double layer is of central importance whenever a charged surface and a charged fluid meet. For example, a charged solid in contact with an electrolyte results in a diffuse ion cloud that screens the surface charge density on the solid surface. Other examples are found in colloidal dispersions, proteins, DNA and electrochemical cells. In this talk, the physics of electric double layers and some recent developments will be covered. I will discuss how electric double layers affect the phase behaviour and effective interactions of colloidal dispersions, but also how the shape of the double layer couples to the shape of a colloidal particle. Finally, I will briefly discuss recent work on electric double layers out of equilibrium, where flow-induced electric fields are coupled to charge-regulating, charged walls.
