Abstract
Abstract The structures, stabilities, and electronic properties of the single‐vacancy‐defected fullerenes, C 60 and C 70 , and the single‐ and double‐vacancy‐defected single‐walled carbon nanotubes (SWCNTs) were studied within density functional theory. The isomerization barriers for the single‐vacancy‐defected C 60 on the triplet potential energy surface (PES) are lower than those on the singlet PES. The symmetric double‐vacancy‐defected (10,0) SWCNT is the most stable one among the models investigated. According to the analyses of frontier molecular orbitals (FMOs), nature bond orbitals, and local density of states, introduction of vacancy on the SWCNT decreases the band gap of semiconducting SWCNT, increases the band gap of conducting SWCNT, destructs the π conjugation of the FMOs, and gives rise to enhanced chemical activity. © 2009 Wiley Periodicals, Inc.

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
