Facilitated Olefin Transport in Swollen-State Membranes via Cost-Effective Silver Nanoparticles
Bibliographic record
Abstract
This work reports an efficient propylene/propane separation achieved by a swollen, facilitated transport nanocomposite membrane. This membrane is fabricated with cost-effective Ag NPs, derived from AgNO 3 as the precursor material, with a positive polarization introduced by 7,7,8,8-tetracyanoquinodimethane (TCNQ). The charged nanoparticle surface, combined with the chitosan matrix, contributes to a uniformly dispersed and well-stabilized distribution of the smaller Ag NPs. The moisture in the water-swollen membrane offered an ideal microenvironment for undocking counterions and migrating olefin molecules through reversible complexation. By optimizing the carrier and TCNQ weight ratio, the CS/AgNP/TCNQ membrane exhibits an outstanding separation performance, including a propylene permeability of 19.4 Barrer and an ideal selectivity of 56.6. The CS/AgNP/TCNQ membrane maintained its separation performance and stability in gas permeation for up to 120 h.

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.
