Coating of High Density Polyethylene (HDPE) with Silver Compounds and Their Antimicrobial Activity in vitro
Bibliographic record
Abstract
Antimicrobial activity of HDPE coated with Ag7O8NO3, Ag2O, Ag2CO3, Ag2SO4, etc. and their antimicrobial efficacy was investigated in comparison with commercially available materials containing silver and/or silver compounds. Both cidal and static activities of HDPE treated with silver compounds was investigated in vitro. For this purpose, gram positive organisms, e.g. Staphylococcus aureus, or gram negative organisms, e.g. Pseudomonas aeruginosa, or fungi, e.g. Candida albicans, were used. Samples prepared in this work have shown a strong antimicrobial activity against tested micro-organisms. The strong antimicrobial activity of silver oxysalt coated HDPE was attributed to the presence of higher oxidation states of silver ions e.g. Ag2+ and/or Ag 3+. The results have clearly shown that the coated samples produced in the present work exhibited comparable or even better antimicrobial behaviour than commercially available samples which contained significantly higher levels of silver.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
