Competitive adsorption of atmospheric trace gases onto ice at 228 K: HNO<sub>3</sub>/HCl, 1‐Butanol/Acetic acid and 1‐Butanol/HCl
Bibliographic record
Abstract
For HNO3/HCl, 1‐butanol/acetic acid and 1‐butanol/HCl, adsorption isotherms have been measured at 228 K in an ice‐coated flow tube with both gases present at pressures between 10−6 and 10−4 torr. For HNO3/HCl, the uptake of each gas is lowered by the presence of the other in the surface saturated regime, but the total surface coverage of adsorbed gases is similar to the coverage of HNO3 adsorbing alone. There is no delay to the onset of the displacement of one adsorbed acid by the other and HNO3 bonds more strongly than HCl. Competition also occurs between 1‐butanol and acetic acid in the saturated regime of their isotherms, but not in a manner consistent with a two‐species Langmuir model. By contrast, 1‐butanol is not affected by the presence of a saturated surface of HCl.

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.
