Resonant control of electrochemical oscillations

Article Abstract:

The resonant control strategy (RCS) technique for taming the aperiodic current oscillations observed during the anodic dissolution of copper in an acidic medium is applied. The study results indicate that resonant forcing can indeed be successfully applied to convert chaotic dynamics to periodic dynamics of lower complexity in dissipative electrochemical systems and that resonance between the oscillatory system and the periodic perturbation might occur at certain frequencies.

Dynamics of a two-dimensional model for electrochemical corrosion using feedback circuit and nullcline analysis

Article Abstract:

A nullcline technique was combined with a method based on the feedback circuits found in the Jacobian matrix to investigate a two-dimensional model of electrochemical corrosion. The combined approach was able to identify regions in parameter space where the model system displays stable periodic or/and multistationary oscillations. Results from the numerical integration of the system were found to be in good agreement with those derived using the two techniques.

Electrochemical construction of novel C60 derivative/PPV composite adlayer on Cu(111) and their current/voltage characteristics

Article Abstract:

A well-ordered composite adlayer of HSC60 and BH-PPV can be prepared on Cu(111) in solution by electrostatic interactions between the two molecules. The results indicated that changing component in the monolayer could control the current/voltage characteristics.
