TL;DR: In this paper, a square-wave potential anodizing procedure to obtain noble metal surfaces with both a controlled roughness and a reproducible electrochemical response is presented, where the influence of the characteristics of the square wave potential perturbation are systematically studied.

TL;DR: In this article, the authors proposed a method for electrochemical faceting of polycrystalline metal wires, which can be applied either electrochemically through conventional voltammetry in the H and O electroadsorption/electrodesorption potential range, or by scanning electron microscopy.

TL;DR: In this article, the changes in surface structure of polyfaceted single crystal platinum spheres subjected to repetitive square-wave potential treatments in acid solution have been studied and the dependence of the prevailing type of change on symmetry, potential limits and frequency of the periodic potential has been determined.

TL;DR: In this article, the electrochemical properties of ball milled mixtures of annealed ZrCrNi alloy with powders of the phases Zr 7 Ni 10, Zr 8 Ni 21 and Zr 9 Ni 11 are studied.

TL;DR: In this article, a new electrochemical procedure to obtain platinum electrode surfaces with preferred orientations from bulk polycrystalline platinum is presented, which involves the application of repetitive potential sweeps at high frequencies to a poly crystal-platinum electrode under carefully selected potential perturbation conditions.
