The effect of HCl adsorption on the structure and dynamics of the ice surface
Bibliographic record
Abstract
Neutron diffraction and quasi-elastic neutron scattering experiments together with molecular dynamics simulations were performed to investigate the effect of HCl adsorption in the sub-monolayer range on the structure and dynamics of a thin ice Ih film deposited on a MgO (100) substrate. We show that surface melting occurs in the supported pure-ice film down to about 8 K below the normal melting temperature of bulk ice Ih. Upon HCl adsorption, the surface melting temperature is still lowered by 15 K at HCl amounts corresponding to 0.3 and 0.6 monolayer. Results of simulations can satisfactorily interpret the lowering of the melting temperature due to the support and to HCl adsorption. Upon adsorption of one HCl monolayer, HCl dihydrate is formed at 220 K and the film becomes amorphous at 250 K. The results are discussed within the context of stratospheric and upper tropospheric/lower stratospheric chemistry. PACS Nos.: 68.55-a, 61.12-q, 31.15Qg, 82.33Tb

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.
