Role of non-Framework Aluminum Species for the Formation of V Center on Zeolites
Bibliographic record
Abstract
The role of the non\|framework aluminum species for the formation of V center at high temperatures on H\|MCM\|22 and H\|ZSM\|5 with different crystal sizes was studied using electron spin resonance technique. A set of six\|lines signal (denoted as A, g =2.048) was observed on H\|MCM\|22 after heat\|treatment under flowing helium, and its intensity increased with temperature. The paramagnetic center was identified as a hole of an electron trapped on oxygen atom bonding with a nearby framework aluminum atom. The formation of signal A might be related to the non\|framework aluminum species, which was further evidenced on the H\|ZSM\|5 with different crystal sizes by ESR technique. The mechanism might involve an electron transfer from the lattice oxygen to the vacant orbit of the non\|framework aluminum species.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
