Particularly, the fast redox reactions (Peaks 2, 4, 5, and 6) involve adsorbates which cause a more or less constant interface capacitance ([I.sub.p] = Cv).
The remarkable capacitive behavior of SBO-1: 3 is attributed to the introduction of oxygen vacancies, which greatly improve the free-electron concentration and thus increase the electron mobility and enhance the rate of redox reactions [51].
The embedding of the reactants in the silica matrix followed by the redox reaction with formation of carboxylate type precursors (oxalate, malonate, and succinate, respectively) and their thermal decomposition allowed the obtaining of 70% Co[Fe.sub.2][O.sub.4]/30% Si[O.sub.2] (wt%) nanocomposites.
(24) The electrospray mass spectroscopy (ES/MS) spectrum evidenced the ionic species of the redox reactions and the oligomers where the later species primarily stabilizes the latex particles.
Thus it could be concluded that increasing the concentration of reducing sugars equalizes and conforms the redox reaction between starch and silver ions and so means increasing the affinity for building of silver clusters.
Similar results have been reported for the redox reaction of [S.sub.2][O.sub.8.sup.2-] [17-19].
This indicated that the experimental data does not represent the actual initial redox reactions of the species and the cell was not fully discharged during the previous charge-discharge cycle.
Overall results showed that the graphite electrode modified with nickel oxide nanoparticles, the myoglobin redox reactions are catalyzed.
Note that the direction of the reaction in the case of the C[O.sub.2] [right arrow] C[H.sub.4] reduction was flipped to reflect what actually happens in this redox reaction in nature.
Using nanotubes to transport electrons to where the redox reaction occurs is very attractive.
Exhaust gas from an internal combustion engine comprises of toxic gas and pollutants; automotive catalytic converter devices are used in vehicles to convert these gases into less harmful emissions by catalyzing a redox reaction.
