Voltammetric Modeling of the Kinetics Involved in the Nickel Deposition onto Nickel
Bibliographic record
Abstract
A comprehensive physicochemical model is used to account for the nickel electrodeposition in sulfate media employing a rotating disk electrode. The model accounts for the nickel deposition, H+ and water reduction. These reactions involve the reduction of Ni(II) by two consecutive 1-electron transfer steps and the H+ and water reduction via the two-step Volmer-Tafel mechanism. Diffusion and convection are considered in the mass-transport balances. Reasonable fits of the model to the experimental data were obtained at different NiSO4 concentrations. Further insights of this system show that the reduction process starting from the open circuit potential to more negative potentials occurs in the following order: H+ reduction, nickel deposition and water reduction. The computation of other variables involved in the model such as the surface pH and concentrations provide additional support to those finds elucidated with the model.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
