Electrochemical Formation of an Ultrathin Electroactive Film from 1,10-Phenanthroline on a Glassy Carbon Electrode in Acidic Electrolyte
Bibliographic record
Abstract
The electrochemical reduction of 1,10-phenanthroline in aqueous acidic electrolyte at a glassy carbon electrode led to the covalent modification of the electrode. Thereafter, the deposited film can be switched to an electroactive form by electrochemical oxidation. An electroactive film can be also generated by alternate reductive and oxidative voltammetric cycling in a 1,10-phenanthroline/aqueous sulfuric acid solution. First, the electrochemical procedure for the formation of a film is presented. Second, the morphology and chemical structure of 1,10-phenanthroline coatings were investigated by atomic force microscopy, time-of-flight secondary ion mass spectrometry, X-ray photoelectron spectroscopy, and electrochemical techniques. The ultrathin (<15 nm) electrodeposited films consist of oligomeric species. The coatings deposited in alternate and/or continuous reductive and oxidative steps contain oxygen atoms incorporated into the oligomer backbone. The preliminary results point out the formation of a dione derivative that is responsible for the electroactivity of the grafted layer.

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.
