Atomic Oxygen Production and Exploration of Reaction Mechanisms in a He‐O<sub>2</sub> Atmospheric Pressure Glow Discharge Torch
Bibliographic record
Abstract
Abstract Summary: This article reports on the performance of a miniature APGD‐t conceived for the production of reactive species participating in bio‐applications. Two operating parameters were varied: the plasma‐forming gas flow rate (0.5–1.5 slm He) and the flow rate of O2 (0–50 sccm), which was injected downstream from the plasma‐forming zone, and which was used as a source of reactive species. The production of reactive species (O) was optimized, and the air entrainment in the plasma jet was minimized for a He gas flow rate of 1–1.5 slm and an O2/He volumetric ratio of 0.3 vol.‐%. A survey of the possible reaction pathways in the afterglow plasma jet suggests that the reactive species present in the plasma afterglow, and possibly reaching a remote substrate, are metastable He(23S), ground state O, OH, O2 (a1Δg), O2 (b1Σg+), N, N2, N and O3.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
