Investigation of the Pore Structure of As-Prepared and Purified HiPco Single-Walled Carbon Nanotubes by N<sub>2</sub>/Ar AdsorptionImplication for H<sub>2</sub> Storage
Bibliographic record
Abstract
Open single-walled carbon nanotubes (SWNTs) are attractive as potential storage media for hydrogen gas. The present paper investigates the micropore structure of HiPco SWNTs samples, as studied by nitrogen and argon adsorption technique at low pressures. The proportion of open SWNT is estimated with the Horvath−Kawazoe method. The results show that as-prepared samples may contain as much as 40% open SWNTs, whereas the oxidative purification process reduces this amount significantly. X-ray diffraction and Raman spectroscopy show that the Horvath−Kawazoe method is reliable for estimating the diameter of open SWNTs. In addition, the Horvath−Kawazoe method appears to be sensitive to species adsorbed in the outer grooves.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
