Abstract

fetched live from OpenAlex

The stability of Pd impregnated MCM-41 (Pd/MCM-41) at mass per cent loadings of Pd of 0.12 and 1.2% was investigated over 50 days. Results showed that the silica in Pd/MCM-41 dissolves at a lower rate than in pure MCM-41 and is likely metastable with respect to amorphous silica. Dissolution rates were lower at a higher mass per cent loading of Pd. Simulations of Pd/MCM-41 dissolution kinetics made using Phreeqci indicated log dissolution rate constants of −12.7 and −12.9 for 0.12 and 1.2% Pd/MCM-41, respectively.

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.
