Abstract

fetched live from OpenAlex

Regular nanometer scale structures of alternating layers of Au and Pt have been produced by a process of repeated rolling, cutting and stacking. When the interlayer spacing is reduced to approximately 6 nm, a process of partial local homogenization is observed resulting in a non-equilibrium, approximately homogeneous, solid solution of Au and Pt. This product was formed at or near room temperature; it is thermodynamically unstable. It is postulated that the solid solution is formed by a discontinuous homogenization process which depends on the coupling of plastic deformation, grain boundary diffusion and grain boundary migration.On a produit des structures régulières, à l’échelle du nanomètre, de couches alternées de Au et de Pt par un procédé de laminage, de coupe et d’empilage répétés. Lorsque l’espace entre les couches est réduit à approximativement 6 nm, on observe un procédé d’homogénéisation locale partielle résultant en une solution solide de non-équilibre et approximativement homogène de Au et Pt. Ce produit se formait à ou près de la température de la pièce et il est instable du point de vue de la thermodynamique. On postule que la solution solide est formée par un procédé discontinu d’homogénéisation qui dépend du couplage de la déformation plastique, de la diffusion aux joints de grain et de la migration des joints de grain.

Not 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.
