Preparation and characterisation of a new stainless steel/Bi<sub>2</sub>O<sub>3</sub> anode and its dyes degradation ability
Bibliographic record
Abstract
Stainless steel/Bi2O3 anode was synthesised by electrodeposition from acidic Bi (III) solution on stainless steel substrate and calcination at 500°C. Characterisation by SEM, EDX, XRD and TGA revealed that the anode surface was fully covered with pure α‐Bi2O3, which formed a inhomogeneous and porous coat. Three dyes with different chromophores, namely: Reactive Blue 19, Methylene blue and Reactive Orange 4 were completely decolourised by electrochemical oxidation at the synthesised anode in the presence of hydrogen peroxide. Decolourisation followed the pseudo‐first order kinetics model for all the three dyes. Decolourisation rates are sorted in descending order: Reactive Orange 4 > Reactive Blue 19 > Methylene Blue. For all the three dyes, an increase of the initial dye concentration caused the decrease of the reaction rate constants. At higher initial dye concentrations, the decolourisation times were significantly prolonged for all the three dyes, however, the complete decolourisation was done as well.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
