“domino effect”). The role of bone dominoes performing here as ring of carbon
atoms forming the nanotube, and the nature of this phenomenon is quite different.
Recent studies show that for nanotubes with diameters ranging from 2 to 6
nm, there are two stable equilibrium states;
• Cylindrical (tube no collapses) and;
• Compressed (imploded tube) with different values of potential energy (the
difference between which and can be used as an energy source).

“Domino effect” in a carbonnanotube. (a) The initial form of carbon
nanotubes is cylindrical. (b) One end ofthe tubeis squeezed. (c), (d) Propagation of domino
waves; the configuration of the nanotube 15 and 25 picoseconds after the compression of
its end. (e) Schematic illustration of the “domino effect” under the influence of gravity.
The switching between these two states with the subsequent release of energy
occurs in the form of waves arising domino effect. The scientists have shown that
such switching is carried out in carbon nanotubes with diameters of 2 nm.
A theoretical study of the “domino effect” was conducted by using a special
method of classical molecular dynamics, in which the interaction between carbon
atoms was described by van der Waals forces.
