Abstract
Urban films are formed on impervious surfaces in urban environments and are composed of a complex mixture of organic and inorganic compounds. In this thesis, the interaction of film components with light and atmospheric oxidants was investigated. Two separate but related projeci:s were undertaken. The photoenhancement of the heterogeneous reaction of ozone with solid pyrene films (SF pyrene) and pyrene contained in model urban films (UF pyrene) was examined using a laser-induced fluorescence technique. The ozonation of SF pyrene displayed a moderate light enhancement, the magnitude of which is insufficient to explain previous observations of light-enhanced ozone uptake by solid pyrene surfaces. These results indicate that surface reactivity cannot always be correctly predicted using gas-phase observations. A suite of environmentally relevant photosensitizers were tested for their ability to enhance nitrate photolysis on model urban film surfaces. No enhancement was observed in the presence of any of the additives.

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
