Global Analysis for the measurement of electrochemical parameters with cylindrical electrodes
2012, Electrochimica ActaCitation Excerpt :It is noteworthy that all these investigations are based on comparisons of simulated responses derived from an assumption about the potential dependence of the electron transfer rate whereas Global Analysis will directly generate this information. While the comparative method has its merit, the Global Analysis method has been proven to be more objective than trial and error based comparisons [2]. Global Analysis has been successfully demonstrated for planar [1] and spherical [3–5] electrode geometries where uniform surface concentrations arise due to the uniform accessibility of the electroactive species to all regions of the electrode surface.
Reversible dimerization of anion radicals: Studies of two cyanopyridines
2011, Journal of Electroanalytical ChemistryCitation Excerpt :Voltammetric studies of 2-, 3- and 4-cyanopyridine in liquid ammonia showed that 2- and 4-cyanopyridine both give a reversible one-electron reduction to a persistent anion radical whereas the reduction of 3-cyanopyridine proceeds irreversibly in an overall one-electron process with the product postulated to be a dimer [6]. The stability of the anion radical of 4-cyanopyridine has been confirmed in studies with DMF or acetonitrile as solvent [7–11]. In a related system, Carelli et al. isolated four dimers from the electrochemical reduction of 3-cyano-1-methylpyridinium iodide in aqueous media.
Incorporating electrode kinetics into the convolutive modeling of reactions at planar, cylindrical and spherical electrodes
2001, Electrochimica ActaCitation Excerpt :The accuracy of a digital simulation technique is usually ascertained from a comparison of I(E) with theory, using the known limiting cases that are available. Alternatively, for the case of quasi-reversible electron transfer at electrodes which are planar or spherical, a procedure known as global analysis [2,11–14] exists which uses every potential–current data pair from a cyclic voltammogram to calculate the kinetic, thermodynamic and transport parameters that describe the process. This global method is based on a convolution procedure in which M(t) is calculated from known values of I(t) using the convolution algorithm (Eq. (16)) and the appropriate g(t) function.
