Abstract

fetched live from OpenAlex

Plasma polymerized coatings (PP) are increasingly used for biomedical applications in contact with body fluids. We optimized and studied the stability, mechanical properties, and adhesion in air and aqueous media of amine (NH 2 )‐rich PP in low‐pressure r.f. plasma from [NH 3 /C 2 H 4 ] mixtures (L‐PPE:N). Quartz crystal microbalance with dissipation monitoring (QCM‐D) revealed partial dissolution or water‐uptake (swelling) in real‐time in various solutions, which helped identify the best gas mixture ratio for compromise between stability and high concentration of (NH 2 ) groups. Nanoindention revealed strong decrease of Young's modulus and hardness in water. Finally, a Cross‐Hatch peel test was used to optimize L‐PPE:N adhesion on poly(tetrafluoroethylene) (PTFE): plasma pre‐treatment prevented both dry and wet delamination.

Teacher imitation

Not 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.
