Polypyrrole/Poly(Methylene Blue) Composite Electrode Films on Stainless Steel
Bibliographic record
Abstract
Polymerized methylene blue films have been shown to be efficient electron mediators for biological redox compounds. Previously these films have been deposited on noble metal and carbon substrates. In this work, methylene blue has been polymerized on stainless steel by first applying a layer of an electronically conductive polymer to inhibit passivation or corrosion of the metal and to increase the active surface area. The redox activity of the resulting electrodes has been examined by electrochemical impedance spectroscopy and fit to an equivalent circuit model for conductive polymers. The film with methylene blue shows a large decrease in charge transfer resistance, from 130 Ω to 15 Ω, when compared to the bare polypyrrole film. The stability of the films was studied by measuring the impedance changes over time when stored in aqueous solutions. Degradation of the films was found to depend mostly on the doping ion used in the polypyrrole synthesis. NADH oxidation was also measured at different concentrations by CV.

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.
