ZIF‐based water‐stable mixed‐matrix membranes for effective CO<sub>2</sub> separation from humid flue gas
Bibliographic record
Abstract
Abstract Water stable mixed‐matrix membranes (MMMs) were developed to help control global warming by capturing and sequestrating carbon dioxide (CO 2 ) from humid flue gas originated from burning of fossil fuels. MMMs of different compositions were prepared by doping glassy polymer Ultrason ® S 6010 (US) with nanocrystals of zeolitic imidazolate frameworks (ZIF‐302) in varying degrees. A solution‐casting technique was used to fabricate various MMMs to optimize their CO 2 capturing performance from both dry and wet gases. The prepared composite membranes indicated enhanced filler‐polymer interfacial adhesion, consistent distribution of nanofiller, and thermally stable matrix configuration. CO 2 permeability of the membranes was enhanced as demonstrated by gas sorption and single gas permeation tests carried out under dry and moist circumstances. As compared to neat Ultrason ® membrane, CO 2 permeability and expected CO 2 /N 2 permselectivity of the mixed membrane doped with 40 g/g ZIF‐302 nanocrystals were significantly enhanced. In contrast to the majority of previously reported membranes, key features of fabricated MMMs include their structural stability under humid conditions coupled with better and unaffected gas separation performance.

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.
