Welcome to the CONDECON Home Page

The kinetic convolution technique pioneered by CONDECON in the 1980s is now much supplemented to provide a complete treatment package for the electrochemist and those in a teaching environment.

The determination of the mechanism and appropriate parameters of electrochemical reactions has importance in many branches of chemistry ranging from inorganic transition metal complexes to large polymeric molecules of organic origin.
The most commonly used methods of deriving this information involve voltammetric techniques where all currents are measured as a function of time and imposed potential. However, even with the simplest reaction, the resultant plots cannot be readily described in analytical form due to distortions produced by other or successive electron transfer processes.

In a voltammetric experiment, the current magnitude is proportional to the flow of the electroactive species AT the electrode (i.e., the concentration gradient) and by observing the current as a function of time we hope, via mathematical treatment of an appropriate model, to determine the electrode concentrations from the current history. In many important mechanistic examples, this history dependence, leading to expressions of concentrations, is contained in convolutions of the current from the onset of the experiment and time.  Recognizing this, leads via computation to a ready means of assessment of adherence of such data to the model involved and the determination of appropriate parameters. This approach is essentially CONvolution - DECONvolution voltammetry.

The digital simulation methods of CONDESIM are supplemented by CONVOSIM in which the solution of the Fickian differential equations rather than the differential equations themselves are used to provide data. This is unique to CONDECON and provides an insight into the mathematical treatment of diffusion in electrochemical systems.
