Abstract
Interactions between reaction-diffusion systems and aggregated host environments are a subject of widespread interest. In this work, the behavior of the {Belousov-Zhabotinsky} reaction was investigated in a micellar environment formed by the zwitterionic surfactant {N-tetradecyl-N,N-dimethylamine} oxide {(C14DMAO).} The appearance of an induction period with a threshold-like dependence upon the surfactant concentration, was detected at {[C14DMAO]�=�5.0�נ10-3�mol�dm-3.} These new features were explained in terms of the segregation ability typical of the amphiphilic self-assembling systems. Numerical simulations were also performed to confirm the proposed mechanism.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
