Ynthesis and Characterization of Nonstructural MG2NI with Replacement Diffusion Method
Bibliographic record
Abstract
Nonstructural Mg2Ni powder was prepared by replacement-diffusion method. The structure of the Mg2Ni powder was investigated by X-ray diffraction and transmission electron microscopy. Crystallographic structure analysis showed that the synthesized sample powder was constituted with Mg2Ni and a small fraction of MgO. The TEM image in low-resolution indicated that the diameter of the synthesized Mg2Ni powder was in the range of 20~80 nm, and the high-resolution transmission electron microscope (HRTEM) image suggested that the interlinear spacing of (113) lattice planes was 0.229 nm, and the specific surface area examined was 50 m2 /g. The electrochemical hydrogen storage capacity of the Mg2Ni power was also measured in this work. It was 82.5 mAh g-1. The reasons of the low capacity hydrogen storage and decrepitating were analyzed, and the mainly cause were the grievous oxidation of the powder and the pulverization.

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.
