Cave airflow mechanism of a crevice-type cave: A case study from Czechia

open access: yesInternational Journal of Speleology, 2020
At present, crevice-type caves are investigated mainly by means of geomorphic and geophysical methods. Microclimatic research of this type of caves is underrepresented and is often limited to temperature and humidity measurement only.

Effect of defects on the motion of carbon nanotube thermal actuator

open access: yesNanotechnology Reviews, 2019
Using molecular dynamics simulations, we investigate the movement behavior of double-walled carbon nanotube containing single atom vacancy defect and Stone–Wales defect. The carbon nanotube thermal actuator consists of a short outer tube and a long inner
