INTERMITTENT INTERFACIAL TRANSFER - A DYADIC MODEL

An interfacial mass transfer system was studied consisting of an oil l ayer of nitrobenzene containing iodine and potassium iodide, imposed b etween two aqueous phases, one of which contained the surfactant hexad ecyl-trimethylammonium bromide. Intermittent and piecewise constant do mains of variations of electric potential have been observed. A dyadic model capable of explaining multi-scale transfer phenomena through hi erarchically structured interfaces is proposed. Actual interpretations of dyadic time and of dyadic derivative are given. The recorded inter mittent signal is expressed in terms of orthogonal Walsh - Hadamard fu nctions. Since the studied system shows similar output potential patte rns to the observed biological patterns, potential applications for ad aptive sensors and technologies are emphasized.
