Abstract

fetched live from OpenAlex

A modified elastic honeycomb model is presented to study elastic buckling of single-walled carbon nanotube ropes under high pressure. Simple formula is given for the critical pressure as a function of the Young's modulus and the thickness-to-radius ratio. For single-walled carbon nanotubes of diameters around 1.3 nm, the predicted critical pressure is about 1.8 GPa, which is in excellent agreement with the known data reported in the literature. This suggests that the elastic buckling would be responsible for the pressure-induced abnormalities observed for vibration modes and electric resistivity of single-walled carbon nanotube ropes.

Full frame distilled prediction

Teacher imitation

Not 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.
