| Research Abstract |
Two liquid membrane oscillators composed of an aqueous solution containing cetyltrimethylammonium chloride (CTACl) and alcohol, W1 and W1', a nitrobenzene solution containing picric acid, O, and pure water phase, W2, were connected through O and W2 as common phases. The oscillations of two membrane potentials synchronized each other depending on the distance between the oscillators. The synchronization was attended by the propagation of potential pulse from one side to another with a velocity of 15 cm/s. It has been demonstrated that the propagation of oscillation pulse was dominated mainly by the interfacial conduction process and that the interfacial diffusion and distribution of Cl- played a crucial role.
