Abstract
Vulcan carbon electrodes of varying PTFE-content (20 w.% and 35 w.%) were synthesized using a sol-gel process. Electrochemical fluorination was carried out over a range of potentials for fluorine generation (4 to 8 V) in molten, KF·2HF electrolyte at ~90 °C. Electrochemical behaviour of PTFE-embedded carbon electrodes was compared to both passivated and non-passivated graphite and amorphous carbon electrodes. An attempt to correlate the amount of embedded PTFE with the degree of passivation on carbon electrodes was made. This was used to compare the non-wetting characteristics of an electrochemically passivated carbon electrode to those of an artificially “passivated” electrode. PTFE contents in the embedded electrodes were confirmed using TGA. The effects of surface and embedded C-F compounds on the electrical properties of the different electrodes were investigated using AC impedance.

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 it
