Electrochemical origin of hysteresis in the electron-transfer reactions of adsorbed proteins: contrasting behavior of the "blue" copper protein, azurin, adsorbed on pyrolytic graphite and modified gold electrodes
Article Abstract:
Cyclic voltammetry over a wide range of scan rates shows that the apparent reduction potential depends on the scan rate and initial polarization potential. However, in order to determine these effects, the voltammetric behavior of azurin adsorbed at pyrolytic graphite "edge" plane (PGE) is compared with results obtained using gold electrodes modified with a self-assembled monolayer of hexanethiol or decanethiol.

The electro-reduction of carbon dioxide in dimethyl sulfoxide at gold microdisk electrodes: current / voltage waveshape analysis
Article Abstract:
The electro-reduction of carbon dioxide is examined by using linear sweep and cyclic voltammetry in dimethyl sulfoxide electrolyte solutions at polycrystalline gold microdisk electrodes. The kinetic parameters for the reduction process are deduced from this waveshape approach and the charge-coefficient is found to be approximately 0.43 plusmin 0.05.

Solvent effects on osmotic second virial coefficient studied using analytic molecular models: application to solutions of C60 fullerene
Article Abstract:
The osmotic second virial coefficients (OSVC's) are calculated analytically for some molecular models in which the solvent is taken into account explicitly. The studies reveal that the solute-solvent interaction has a determinant influence on the observed Osmotic second virial Coefficient (OSVC) value.
