Estimates of the alpha parameter of the gamma distribution used to model rate variation among sites indicated that there are genes ranging from, those with highly conserved sites and little rate heterogeneity, to others with highly heterogeneous rate distributions, whereas most fell generally under a moderate form of the former pattern.
The DWCNTs showed an improved heterogeneous rate constant.
Heterogeneous rate constants were determined at platinum and at mercury electrodes.
Heterogeneous rate constant for the reduction, Nd II)/Nd(0) was estimated from the convoluted voltammograms.
The heterogeneous rate constant was varied in all instances, reversible, quasi-reversible, and near-irreversible cases being considered.
The diffusion coefficient and standard heterogeneous rate constant of ferrocene are both smaller in polymer solvents than in monomeric solvents.
The diffusion coefficients for oxygen and superoxide, and the heterogeneous rate constants were obtained with a fit to experimental voltammograms.
Effects of anodic peak potential (Epa), anodic peak current (Ipa) and heterogeneous rate constant (k0) have been discussed.
The maximum pseudo-first-order heterogeneous rate constant was approximately 0.05 cm min−1, which is comparable to more commonly used cathode materials such as nickel.
The heterogeneous rate constant (k′ME) for the reduction of O2 at the modified electrode was determined by using a Koutecky-Levich plot.
Under the optimum conditions, some kinetic parameters of modifier such as electron transfer coefficient and heterogeneous rate constant (k) for hydrazine were obtained.
