Interlayer grafting of glycidol (2,3-epoxy-1-propanol) on kaolinite
Bibliographic record
Abstract
An organic–inorganic nanohybrid material was prepared by grafting glycidol (2,3-epoxy-1-propanol) on the interlayer aluminol groups of kaolinite (K) using DMSO–K precursor as a starting material. The results of the physicochemical characterization of the synthesized materials (XRD, FTIR, DTA–TG, 13C and 29Si CP/MAS NMR) confirm that the grafting reaction of glycidol involved the opening of the oxirane ring. The resulting nanohybrid material is similar to the one obtained by the interlayer grafting of glycerol (M. Janek, K. Emmerich, S. Heissler, and R. Nüesch. Chem. Mater. 19, 684, (2007)). Approximately, one glycidol moiety is grafted on each structural unit of kaolinite to afford a material with the chemical composition Al2Si2O5(OH)4[C3H6O2]0.9.Key words: clays, clay minerals, kaolinite, intercalation, grafting, nanohybrid materials, DMSO, glycidol, glycerol, oxirane.

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.
