The effect substitution of lanthanum-aluminate oxide of the catalytic performance of La1-xSrxAlO3-δ (x = 0.1, 0.2, 0.3) for methane oxidation, pp. 211-216
Bibliographic record
Abstract
This work shows the catalytic activity of the methane oxidation reaction on catalytic powders such as perovskite -aluminate oxide La1-xSrxAlO3-δ , with x = 0, 0.1, 0.2, 0.3.The La1-xSrxAlO3-δ (0<x<0.3)matrix was prepared by the co-precipitation method, the pure phase was characterized by X-ray diffraction (XRD) , thermal and differential gravimetric analysis (TG/DSC), Fourier transform infrared spectroscopy (FTIR), Specific surface area (BET).SEM micrographs showed spherical grains and uniform.The maximum catalytic activity of the different La1-xSrxAlO3-δcatalyst (x = 0.1, 0.2, 0.3) for CH4 combustion reactions was observed on the surrogate samples (x = 0.1, 0.2, 0.3) by the analytical system used in gas chromatography (GC) (IGC 1025 FL INTER SMAT).A higher degree of substitution produces an increase in catalytic oxidation activity.

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.
