Design of oscillations across the artificial liquid membrane between water and oil phases

Two types of system were designed which exhibited sustained potential oscillations across the liquid membrane between an aqueous solution (water phase) and a nitrobenzene solution (oil phase). Type I contained a cationic surfactant in water phase corresponding to an organic acid in oil phase, while type II contained an anionic surfactant corresponding to an organic base. The oscillating behaviors were investigated, and the oscillating mechanism was briefly discussed. Simulation on the oscillatory model showed a qualitative agreement between the experimental and computed curves of oscillations.
