Experimental evaluation of the resistance of nitrile rubber protective gloves against TiO<sub>2</sub>nanoparticles in water under conditions simulating occupational use
Bibliographic record
Abstract
Manufactured nanoparticles (NPs), including titanium dioxide nanoparticles (nTiO 2 ), now enter in the formulation of several commercial products. Some studies have been carried out to assess the resistance of protective gloves against NPs, they have generally not considered the conditions prevailing in occupational settings. This study was designed to evaluate the behavior of protective gloves materials against NPs in solution under conditions simulating occupational use. Mechanical deformations, simulating those produced by flexing the hand, were applied to nitrile rubber glove samples in contact with nTiO 2 in water. The first analysis showed that nTiO 2 solution penetrates some of the materials after prolonged dynamic deformations. These results were partly attributed to modifications in the physical and mechanical properties of protective gloves materials that were induced by repetitive mechanical deformations and/or the presence of the colloidal solution.

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.
