Nanostructured and Nanocomposite Light Metal-Based Compounds for Hydrogen Storage
Bibliographic record
Abstract
The present paper is an overview of our recent results on the nanostructural processing and synthesis of complex hydrides in the Mg-M-H (M= Co, Mn, B and Fe) systems by using Controlled Reactive Mechanical Alloying (CRMA) and Milling (CMM) in the magneto-mill Uni-Ball-Mill 5. Under shearing mode of milling the principal nanocrystalline hydride being created in the 2Mg-Co, 3Mg-Mn and Mg-2B mixtures is β-MgH2 whose nanograin size can be immensely reduced to the range of ∼10–5 nm. For the Mg-2B mixture X-ray diffraction seems to provide some evidence for the presence of a small amount of nanostructured Mg(BH4)2. In the 2Mg-Fe mixture amorphization of elemental Mg and formation of amorphous MgH0.6–1.1 hydride is observed.

How this classification was reachedexpand
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.
