Abstract

fetched live from OpenAlex

Abstract A novel photoelectro‐bifunctional electrode (TiO 2 /Ti/TiO 2 ‐Pt) for the rapid determination of chemical oxygen demand (COD) has been developed. The TiO 2 nanotubes, serving as the photocatalyst and the support of the electrocatalyst, were directly grown on both sides of a Ti plate by anodic oxidation. Pt nanoparticles were loaded on one side of TiO 2 nanotubes by the photoreduction method. For the COD determination, the bifunctional electrode exhibits a low detection limit (9.5 mg/L), high sensitivity of 3.55×10 −3 mA/(mg/L COD) and high Cl − tolerance (1400 mg/L). When used for the test of real wastewater samples, the results were in excellent agreement with those determined by the standard K 2 Cr 2 O 7 method.

Full frame distilled prediction

Teacher imitation

Not 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.
