โฆ Synopsis
This paper discusses the dynamics (i.e. the rates of the various charge displacement processes) of electrical double layers after disequilibration, taking the .?gI-electrolyte solution interface as the node1 system. Relaxation studies performed with Ag/AgI electrodes lead to the conclusion that there is a relatively slow step, connected with the transfer of charge through the solid-solution interface. Evidence is given that this step occurs also with colloidal particles under interaction.

Colloidal particles stabilize emulsions both by providing steric hindrance to drop-drop coalescence and by modifying the rheological properties of the interfacial region. The effectiveness of colloidal particles in stabilizing emulsions depends in part on the ability of these particles to reside at
