Abstract
The diffusive properties of thin-layer ethylene vinyl alcohol (EVOH) thin-films often used in vapour barriers and co-extruded geomembranes were studied. Sorption, diffusion and permeation were studied for benzene, toluene, ethylbenzene and xylenes (BTEX) contaminants in dilute aqueous solutions. Films with 32 and 44 mol% EVOH were studied, showing a decrease in permeability with higher EVOH content. Sorption was studied for the EVOH thin-films at room temperature, as well as 30, 40 and 50°C. An increase in sorption of BTEXs was observed at elevated temperatures. Results show that the permeability of these non-polar hydrocarbons decreases with decreasing EVOH content from the 32 mol% thin-film (Pg=15–57 x 10–14m2s–1), to the 44 mol% thin-film (Pg=3–5 x 10–14m2s–1). When compared with the EVOH inner barrier layer of a co-extruded LLDPE/EVOH geomembrane, the co-extruded geomembrane has the lowest Pg (0.7–0.9 x 10minus;14m2s–1). Pg values are significantly lower for EVOH thin-films and co-extruded geomembranes when compared with standard LLDPE, HDPE and PVC geomembranes.

How this classification was reachedexpand
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.
