(Invited) Toward the Isolation of Giant C<sub>120</sub>-C<sub>200</sub> Fullertubes
Bibliographic record
Abstract
The newly reported purification and isolation of pristine and unfunctionalized C90 and C100 fullertubes has generated excitement due to their unique “hybrid” structure of ½-fullerene endcaps, but with a single wall nanotubular belt and mid-section. Unique features of these fullertubes include a (1) defined molecular weight, (2) reproducible structure, (3) pristine tubular belt region, and (4) natural solubility into organic solvents without functionalization or polymer wrapping. Hence, the surface of the fullertube belt region would inherently be smooth and free from surface coatings, derivatization, or oxidation. These features provide a unique molecular architecture for investigating the true nature of electronic and photophysical properties of the fullertube's tubular belt. In this presentation, we will discuss our lab’s recent progress toward the isolation of segmentally longer fullertubes of higher aspect ratios as we seek to move from C120 fullertubes to C150 fullertubes and beyond.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
