Self-Consistent Approach to Global Charge Neutrality in Electrokinetics: A Surface Potential Trap Model

How to describe the ``electric double layer'' that is at the root of all electrokinetic phenomena such as electrophoresis and electro-osmosis? A new theoretical approach, introducing the concept of a surface potential trap and applying the constraint of global charge neutrality rigorously, answers this century-old question in the context of contemporary electrokinetics involving nanoscale systems and time-dependent electric fields.
