Abstract

fetched live from OpenAlex

This work examines the filling fraction limit (FFL) in skutterudite structures using single-crystal X-ray diffraction and electronic structure calculations and concludes that there are no clear, simple trends for the FFL in skutterudites. Our analyses reveal that La is the most preferred filler among the studied fillers due to the larger increases in integrated crystal orbital Hamilton population (-ICOHP). This study also suggests that the FFL is influenced by the bonding and antibonding interactions in the structure, whose strength depends on the available valence electrons, and also by formation of the competing phases.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
