Bibliographic record
Abstract
Abstract The facile technology of hyperthermal hydrogen‐induced cross‐linking (HHIC) has recently been employed to efficiently cross‐link the typical surface modification material of poly acrylic acid (PAA) on polymer substrates, such as polylactic acid substrates, parylene C substrates and hydrophobic polypropylene substrates. This paper systematically studied the HHIC induced self‐cross‐linking of PAA without polymer substrates. It was found that the H was cleaved not only from the CH, but also from the surface functional group COOH, evidenced by both X‐ray photoelectron spectroscopy (XPS) measurement and the water contact angle test. We explained the self‐cross‐linking process as a result of both CC bonding and COOC bonding. Meanwhile, it was also found that PAA on different substrates can also be cross‐linked by secondary electron generated by X‐ray radiation during XPS analysis, which could be the main reason for wide variations of different reported XPS results.

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.
