Surface and Pore Structures of CMK-5 Ordered Mesoporous Carbons by Adsorption and Surface Spectroscopy
Bibliographic record
Abstract
Ordered mesoporous carbons (OMCs) were synthesized in the pore system of SBA-15 aluminosilicates with different Si/Al ratios ranging from 5 to 80. Nitrogen adsorption was used to characterize the pore structure of the aluminosilicates and of the OMCs, whereas the OMC surface chemistry was studied by X-ray photoelectron spectroscopy and static secondary ion mass spectroscopy. The results indicate that the physicochemical properties of the OMCs depended significantly on the acid catalytic activity of the aluminosilicate frameworks, which comes along with the variation of Si/Al ratios. The OMC pore widths and order of the graphene layers followed the same trend as the catalytic activity of the aluminosilicates, whereas the concentration of extraframework species in the aluminosilicates indirectly influenced the mechanical properties of the OMCs. The reasons for this behavior are discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
