Abstract
The crystallization of Ni nanoclusters from the gas phase is investigated with the help of molecular dynamics simulations using empirical tight-binding potentials. In these simulations, the condensation of hot liquid droplets from the gas phase is observed which later crystallize and agglomerate. It is shown that agglomeration of crystallized particles is the dominating growth mode and that the shapes of the final particles are similar to the shapes of experimentally grown Ni nanoparticles. In the second part, the evolution of the structure and the morphology of an agglomerated particle during sintering at 600 and 900K is studied. While in both cases the original disordered interface between the agglomerated particles vanishes, the shapes of the resulting particles differ considerably due to the different surface diffusion rates.

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 it
