Incorporation of Cyclodextrin into Mesostructured Silica
Bibliographic record
Abstract
The incorporation of cyclodextrin (CD) groups inside mesoporous silica frameworks was attempted using two methods: by the grafting of the CD groups into the channels of preformed mesoporous silica hosts and by the direct synthesis of CD-containing mesoporous materials by a one-step process. While the grafting procedure failed to incorporate CD groups inside the pore channels of mesoporous silica substrates, the direct synthesis approach yielded materials whose physical and chemical characteristics (as determined by X-ray diffraction, N 2 sorptometry, transmission electron microscopy, and elemental analysis) were indicative of the presence of CD groups inside the pore channels of the materials. The CD-containing mesoporous materials, denoted as CD-HMS, were prepared by the co-condensation of tetraethoxysilane and a silylated derivative of β-cyclodextrin in the presence of a structure-directing dodecylamine surfactant solution. Materials with CD group loadings up to 0.39 mmol g -1 and uniform pore channels with diameters in the range of 38−42 Å were prepared by this method. Preliminary adsorption experiments using aqueous p -nitrophenol solutions showed that the CD-HMS materials were promising for the removal of organic compounds from water.

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.
