Scholarcy highlights

  • COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research
  • We present classical molecular dynamics simulations demonstrating that single-wall carbon nanotube bundles collapse under hydrostatic pressure
  • The collapse pressures obtained as a function of nanotube diameter are in excellent quantitative agreement with new data presented here for small diameter SWNTs, and the majority of previously published results, there remain some unreconciled contradictions in the literature
  • The collapse pressure is found to be independent of the nanotube chirality, and a lower limit on the largest SWNT that remains inflated at atmospheric pressure is established
  • Collapse pressure of SWNT bundles along loading branch as a function of tube diameter, and as a function of reciprocal diameter, with the six lowest diameters fitted by a linear relationship.Reuse & Permissions
  • Plot of the strongest tangential mode positions for the two types of SWNT materials investigated experimentally, which verifies the dependence of the transition pressure on the diameter of the single-wall carbon nanotubes
  • The arrows highlight the transition pressures.Reuse & Permissions
