PREPARATION OF VANADIUM PENTOXIDE NANOPARTICLE-DEPOSITED ALUMINA SUBMICRON PARTICLES FOR CATALYSTS WITHOUT SINTERING
Bibliographic record
Abstract
The formation of vanadium pentoxide (V₂O₅) nanoparticles immobilized on alumina (Al₂O₃) particles was studied in a methane/oxygen coflow diffusion-flame reactor. V₂O₅ nanoparticles formed by the decomposition of vanadium oxytriethoxide were deposited onto Al₂O₃ particles, which were introduced into the flame together with vanadium oxytriethoxide solution. To immobilize the V₂O₅ nanoparticles on Al₂O₃ particles, rapid cooling with a Laval nozzle was applied to the V₂O₅/Al₂O₃ particles formed in the flame. We found that it was possible to suppress the sintering of V₂O₅ nanoparticles on the Al₂O₃ particles when the Al₂O₃ particles were introduced into the flame at a temperature sufficiently high to soften the surfaces of the Al₂O₃ particles.

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.
