Interfacial vs. Internal Water Transport Resistance of Sulfonated Hydrocarbon Proton-Exchange Membranes
Bibliographic record
Abstract
Liquid-Vapor Water Permeation (LVP) through sulfonated poly(etheretherketone) (sPEEK) proton exchange membranes, measured upon exposure of membranes to liquid water on one side and water vapor on the other, is lower than for Nafion membranes. Thickness-dependent measurements reveal that both internal and interfacial resistances to water transport are larger for sPEEK membranes, despite sPEEK membranes possessing larger water contents and possessing more hydrophilic surfaces. This report brings to attention the importance of organized hydrophilic domains on net water transport, not just within the membrane, which is common knowledge, but also at its surface. © 2013 The Electrochemical Society.

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.
