Abstract

fetched live from OpenAlex

Meso structured MCM 41 titanosilicate with high titanium content has been hydrothermally synthesized under static conditions by a modified approach via a separate hydrolysis procedure during gel preparation The physicochemical properties of this material were characterized by means of XRD, FT IR, UV Vis DRS and catalytic oxidation of 4 methylphenol in the presence of dilute hydroperoxide It reveals that with the addition of TBAOH this novel approach can effectively prevent titanium ions from formation of indissoluble titania species in the mixture at high titanium content Highly ordered product with an MCM 41 hexagonal phase can be obtained with a gel of n(Ti)/n(Si)≤1/4 and relatively low template content During crystallization period, part of titanium ions was incorporated into the MCM 41 framework The addition of TBAOH also resulted in a more cross linked and ordered wall structure

Full frame distilled prediction

Teacher imitation

Not 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.
