Herein. the encapsulation mechanism of nickel atoms into carbon and boron nitride nanotubes is investigated to determine the interaction energies between the nickel atom and a nanotube. Classical modelling procedures. together with the 6-12 Lennard-Jones potential function and the hybrid discrete-continuous approach. https://www.alarecre.com/American-Flag-Color-Block-iPhone-14-Waterproof-Case-p12619/
