Abstract
Abstract Expanding the pore size of mesostructured silica above 2 nm has constituted a breakthrough in materials science. Unfortunately, the lack of recyclability of the costly used surfactant impedes large‐scale implementation of these precisely calibrated nanoreactors. Unlike the commonly used template‐destructive, energy‐intensive protocols, we herein report that gentle treatment of the as‐prepared silica‐surfactant composite with phosphoryl chloride allows for performing two goals in a single action. Concomitant to surface phosphorylation, the released hydrochloric acid disturbs the hydrogen‐bonding of the Pluronic to the silica network, triggering, as a consequence, its easy escape from the mesostructure. The presence of the Pluronic limits oligomerization of the phosphorus reagent inside of the mesostructure, thereby providing better site isolation for acid and cooperative acid‐base functionalities compared to the phosphorylation undertaken through two‐step implying conventional Soxhlet extraction and post‐grafting, as substantiated by gas adsorption and catalytic tests. Besides, this nondestructive approach offers additional assets for template recovery and further recycling.

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
