Molecular-dynamics simulations of capillary imbibition of KI melt into MoS2 nanotubes

► Capillary imbibition of molten salts into sulfide nanotube depends on their lattice type. ► Melts of non-layered iodides have a less pronounced structure of the liquid, than those of layered iodides. ► Crystallization of non-layered iodides within a nanotubular cavity results in the formation of bulk nanowires.
