Periodic Mesoporous Silica-Based Organic−Inorganic Nanocomposite Materials
Bibliographic record
Abstract
The area of periodic mesoporous materials prepared by cooperative assembly in the presence of amphiphile molecules underwent dramatic growth. Among the silica-based materials, many types may be regarded as ordered organic−inorganic nanocomposites. These were divided into five categories: (i) noncalcined amphiphile/silica mesophases, (ii) mesoporous silicas with organically modified surfaces, (iii) expanded mesoporous silicas, (iv) mesoporous organosilicates, and (v) mesoporous silica with occluded organic materials such as polymers. The diversity of such nanocomposites created new potential opportunities in materials sciences, catalysis, separation, and environmental remediation. These applications involved the development of new chemistry not only within the confined pores and channels but also on functionalized surfaces as well as within the channels walls. The current review deals with recent progress in the synthesis, characterization, and applications of each of these types of periodic mesoporous silica-based hybrid materials.

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.
