Abstract
The heat of reaction has been measured for vapor deposition of metal atoms onto clean polymeric substrates. These calorimetric measurements introduce a new technique for the study of metal-polymer interfacial chemistry. Results for three systems are reported here, calcium, chromium, and copper on PMDA-ODA polyimide, and widely different reaction heats are observed in each case. Our results show that calcium deposition is very exothermic at low coverages, with an initial heat approaching 610 kJ/mol. In the case of chromium deposition, the initial heat is quite low, 125 kJ/mol or less, an affect we attribute to the energetic cost of polymer bond disruption. The data for copper deposition show that calorimetry can be used to study fine details of the nucleation and growth process of the metal island film.

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
