Dynamic instability at liquid/vapor interface far from equilibrium

Abstract

Attempt has been made to elucidate the mechanism of electric potential oscillations at oil–aqueous solution interface involving adsorption at oil–vapor interface on a semi-theoretical basis. The mechanism stipulates adsorption of ammonia, amines and pheromones at the liquid–vapor interface followed by transfer of ions through membrane–aqueous solution interface and subsequent interaction of ammonium (amine) ions and carbocations from pheromones with diffusing halide ions from the bulk. Relationship of the above mechanism with sensing mechanism of smell by olfactory nerves has also been pointed out.
