The Front Cover illustrates that while electrochemical arrays of electroactive sites may be extremely random from a geometric standpoint, as the beige array with its Voronoi tessellated unit cells shown at the left, their voltammetric responses become almost indistinguishable from those of fully periodic ones, idealized by the green honeycomb matrix at the right. This occurs as soon as peak‐shaped voltammograms are observed due to full interactions of the diffusion layers generated by individual active sites. This justifies why the theory proposed by Amatore and Savéant almost 40 years ago to describe the behavior of electrochemical networks has always provided solid outcomes even for random ones.
