Zur Rührabhängigkeit des Grenzstromes an teilweise bedeckten rotierenden Scheibenelektroden bei relativ grossen Umdrehungszahlen

Inhibiting properties of benzimidazole films for Cu(II)/Cu(I) reduction in chloride media studied by RDE and EQCN techniques

“…Hence, the micromigration term would become dominant and the pure concentration gradient driven diffusion is not likely to be the limiting step of the overall process. An excellent systematic study of effects due to thin electrodic films has been published by Seveant [93], extending the RDE surface blocking theory of Landsberg [94][95][96][97] and ISE theories based on diffusion-migration in stationary films developed by Buck and co-workers [98][99][100]. We have attempted to enhance it further by using nanogravimetry and molecular film structure elucidation [101,102].…”

Numerical simulation of partially blocked electrodes under cyclic voltammetry conditions: influence of the block unit geometry on the global electrochemical properties

“…The surface blocking of the electrode modifies the absolute and relative rates of diffusive and kinetic flux to the electrode surface [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. These modifications can lead to errors and inaccurate electrochemical interpretation.…”

Electrochemical measurements of mass transfer at surfaces with discrete reactive areas

“…Also, the membrane fabrication process leads to pores which are distributed randomly over the surface, so that regular active site distributions cannot be studied. A second approach has been to employ partially masked, rotating disk electrodes (Scheller et al, 1968(Scheller et al, , 1969(Scheller et al, , 1970. In these systems, limiting currents can be used to provide a direct measurement of the boundary-layer resistance under well-defined hydrodynamic conditions, and a wide variety of site patterns can be produced using photolithography.…”
