Because the presence of small amounts of step-site defects results in visually more roughened surfaces upon corrosion and because of the fact that these facets with a low step

In this contribution, we report on the structural transforma- tion and the surface evolution of Pt(111), Pt(100), and Pt(110) single-crystal electrodes and of a

The previous sections have demonstrated that both the glycerol oxidation selectivity and the oxygen reduction activity of Pt(111) can be tailored through cathodic corrosion.. We

dichloride, adsorbed on pyrolytic graphite, reduction to water occurred in alkaline solution, whereas in acid solution only hydrogen peroxide was formed; the results are compared

Concerning that first petition, Melanchthon (1982:302) comment goes thus: ―Grant that men may know thee as the true living God and Father; that thy word may be preached

In this work, we showed that the cathodic corrosion method can be modi fied to make nonaggregated nanocrystals and nanoalloys by adding PVP 42 to the electrolytes and by

But even on a small scale the inXuence from other networks or from individual speakers (or writers) may have had its eVect. On the other hand, as many histories of the language

In doing so, it was found experimentally that both the concentration and identity of the cation can strongly a ffect the surface area and facet distribution of corroded electrodes,
