Abstract
Ar, N 2, O 2, and H 2 O radio frequency (13.56 MHz) plasma treatments have been carried out on insulator-supported samples of highly oriented pyrolytic graphite (HOPG). The HOPG surface was found to be minimally damaged by all the plasma treatments, which break C−C bonds and form free radicals in the outermost few layers. These free radicals subsequently react, on exposure to air, forming various oxidation products; both XPS and photoacoustic FTIR indicate that these include C−OH, C O, and −COOH. Pt was deposited onto these samples by evaporation, forming nanoparticles. After plasma treatment, the dimensions of the Pt nanoparticles were ∼3.5−4 nm, compared to ∼6 nm on untreated HOPG, and they no longer diffused laterally; this indicates enhanced interfacial adhesion for all these plasma treatments. The occurrence of oxidation products strongly suggests that the increased Pt nanoparticle adhesion to the treated HOPG surface is due to their presence.

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
