Abstract
High Resolution Image Download MS PowerPoint Slide By exposing tetraphenyl-porphyrin (H2−TPP) molecules anchored on a Ag(111) surface to a beam of cerium atoms under vacuum conditions, a selective interaction of the lanthanide with the porphyrin macrocycle is achieved. A novel Ce−TPP species is formed that can be clearly identified in scanning tunneling microscopy data resolving intramolecular features. The electronic structure of the Ce−TPP was characterized by scanning tunneling spectroscopy, identifying molecular resonances that are related to those of coadsorbed Co−TPP. The inhomogenous local electronic density distribution of the dominating Ce−TPP and Co−TPP occupied states was visualized by tunneling spectroscopy mapping. With complementary density functional theory calculations, the geometry and energetics of the Ce-porphyrin bonding was determined.

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
