Abstract
Mixed matrix membranes (MMMs) prepared with 6FDA‐DAM polymer using ordered mesoporous silica MCM‐41 spheres (MSSs), Grignard surface functionalized MSSs (Mg‐MSSs) and hollow zeolite spheres are studied to evaluate the effects of surface modification on performance. Performance near or above the so‐called permeability‐selectivity trade‐off curve was achieved for the H 2 /CH 4 , CO 2 /N 2 , CO 2 /CH 4, and O 2 /N 2 systems. Two loadings (8 wt % and 16 wt %) of MSSs were tested using both constant volume and Wicke–Kallenbach sweep gas permeation systems. Besides single gas H 2 , CO 2 , O 2 , N 2 , and CH 4 tests, mixed gas (50/50 vol %) selectivities were obtained for H 2 /CH 4 , CO 2 /N 2 , CO 2 /CH 4 , and O 2 /N 2 and found to show enhancements vs. single gases for CO 2 including cases. Mg‐MSS/6FDA‐DAM was the best performing MMM with H 2 /CH 4 , CO 2 /N 2 , CO 2 /CH 4 , and O 2 /N 2 separation selectivities of 21.8 (794 Barrer of H 2 ), 24.4 (1214 Barrer of CO 2 ), 31.5 (1245 Barrer of CO 2 ), and 4.3 (178 Barrer of O 2 ), respectively. © 2015 American Institute of Chemical Engineers AIChE J , 61: 4481–4490, 2015

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 it
