“…The gold seals ensured that no meniscus effects were present (9)(10)(11). The well-defined electrode areas were estimated geometrically and measured electrochemically using the method of Wolfe and Caton (12). The counterelectrode was a large gold foil.…”

“…(The cathodic peak current, at scan rates greater than 1 Vs -1, is proportional to the water partial pressure, which supports this stoichiometry.) Under dry argon, the bicarbonate ions decompose by the process 2HCO3-~ COs + HsO + CO~ s- [11] The introduction of dry carbon dioxide results in the reformation of bicarbonate ions by the reaction OH-+ COs ~ HCO3- [12] and their ultimate decomposition via reaction [11]. Further support for reactions [10] and [12] was obtained by introducing carbon dioxide into the wet argon stream.…”

At any partial pressure of water, this caused an increase in the "water response" peak (X).…”

resultant films do not have power conversion efficiencies as large as those obtained for films prepared from other electrodeposition processes. For this process strict control of potential and solution composition is not required to deposit films having Cd/Se ratios close to 1.0. The films are less dense than those prepared using selenosulfite (3c). The bandgap of the film is dependent on the annealing temperature with the minimum bandgap occurring at 350~ or above. On the other hand, the maximum power conversion efficiency requires annealing temperatures of at least 500~ AcknowledgmentThis research was supported in part by a grant to M.

Determination of the oxidation state of solutes in glass-forming melts can be made in situ using electrochemical techniques. Nevertheless accurate voltammetric measurements are perturbed by the simultaneous influence of broader voltamperometric signals and high residual currents. The aim of this investigation was to test various voltammetric methods as well as chronopotentiometry, chronoamperometry and AC impedance plots in order to analyze the electrochemical behavior of a given solute. The Ni(ll) entity was selected, its reduction wave being well-defined. Experiments were carried out over the temperature range from 1148 to 1473 K. INTRODUCTIONGlass manufacture for most applications has been empirically modified over several centuries before scientific understanding of the interactions between the glass-forming melt and the surrounding atmosphere was effective (1).Since the past twenty years, new techniques and economic factors allowed to improve the traditional glass making by a better control of the redox conditions of the melt in the furnace. This state is ruled by the oxygen partial pressure, the oxobasicity of the melt and the temperature of
