Abstract
X-ray photoelectron spectroscopy (XPS) was used to study two interfaces formed between polyethyleneterephthalate (PET) and thin layers of aluminum and zirconium deposited under ultrahigh vacuum conditions. The thicknesses of these layers were estimated to be about 10 and 4 Å respectively. The interpretations were guided by difference spectra, especially for the Zr system, and it was concluded that different interactions operate at these two PET–metal interfaces. For the amounts deposited, Zr bonds especially to O atoms in PET, whereas Al bonds to both C and O atoms; the latter metal shows both bonding to carbonyl groups and direct Al–C bonding to the benzene-like rings. Comparisons were made for the behaviors of these systems on exposure to oxygen, and they were compared further with related systems.

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
