Electrochemistry with stationary disk and ring-disk millielectrodes in magnetic fields
Article Abstract:
Hydrodynamic convection of the electrolyte solution is caused by a magnetic field on electrochemical systems. However, robust analytical solutions are not available because of the nonlinear nature of the hydrodynamic equations and the fact that neither the velocity nor the concentration profile near the electrode is known. A semiempirical treatment of the mass transport was used which provided a formula for the limiting current as a function of electrode area, magnetic field strength, bulk concentration of the redox-active species and the kinematic viscosity of the electrolyte.

Electrochemical formation of contacts between platinum or gold electrodes with the organic charge-transfer salts tetrathiafulvalenium bromide (TTFBr(sub x), x = 0.74-0.79) or bis(tetramethyltetraselenafulvalenium) perchlorate ((TMTSF)2ClO4)
Article Abstract:
The electrochemical formation of contacts between platinum or gold electrodes with the organic charge-transfer salts tetrathiafulvalenium bromide (TTFBr(sub x), x = 0.74-0.79) or bis(tetramethyltetraselenafulvalenium) perchlorate ((TMTSF)2ClO4) was investigated. To this end, conducting crystals of the charge-transfer salts were examined. The needle-shaped crystals were prepared between pairs of platinum or gold electrodes by oxidative electrodeposition. An electrical connection resulted when a crystal growing from one electrode encountered the second electrode.

Ultrahigh specific power electrochemistry, exemplified by Al/MnO4- and Cd/AgO redox chemistry
Article Abstract:
A study was conducted to analyze a unique charge transfer domain from electrochemical processes. A standard three electrode potentiostatic configuration was utilized to carry out cadmium and silver cyclic voltammetry. Planar aluminum and nickel electrodes were then separated by a 30 micron Teflon spacer. In addition, five criteria were observed to determine the electrochemical ultrahigh power domain.
