Recent electrochemical studies of the cathodic reduction of hydrogen peroxide (H 2 O 2 ) on silver electrodes in acidic electrolyte (HClO 4 ) revealed a novel autocatalytic reaction path. Adsorbed hydroxyl groups, OH ad , were proposed to act as the

The impact of global coupling on pattern formation in electrochemical systems with an S-shaped current potential curve is investigated theoretically and compared with the corresponding behavior in systems with N-shaped current potential characteristi

Dispersive chaos is a dynamical state that consists of the repeated, irregular growth and abrupt decay of spatially localized bursts of traveling waves. This state can be observed just above onset in convection in binary fluids at small, negative sep

It is shown that the cathodic reduction of hydrogen peroxide (H2O2) on silver electrodes in acidic electrolyte can proceed by two parallel mechanisms: first, by the ‘normal’ mechanism that has been discussed in the literature, second, by a novel

Applying a constant voltage across an external resistor in series with an electrochemical cell allows the continuous variation of the experimental control mode from potentiostatic to galvanostatic. The model for electrochemical pattern formation pres

Using surface plasmon microscopy we demonstrate that oscillations as well as transitions in the bistable regime during the reduction of S 2 O 8 2− at Ag electrodes are accompanied by wave phenomena. Typical velocities of the waves range from some c

We examined the spatio-temporal behavior of an electrochemical system in the bistable regime, in which the system might take on either a high current density state (active) or a low current density state (passive) at one value of the externally appli
