ABSTRACTDuring the last years carbon-based nanostructures (such as, fullerenes, carbon nanotubes and graphene) have been object of intense investigations. The great interest in these nanostructures can be attributed to their remarkable electrical and mechanical properties. Their inorganic equivalent structures do exist and are based on boron nitride (BN) motifs. BN fullerenes, nanotubes and single layers have been already synthesized. Recently, the fracture patterns of single layer graphene and multi-walled carbon nanotubes under stress have been studied by theoretical and experimental methods. In this work we investigated the fracturing process of defective carbon and boron nitride nanotubes under similar stress conditions. We have carried out fully atomistic molecular reactive molecular dynamics simulations using the ReaxFF force field. The similarities and differences between carbon and boron nitride fracture patterns are addressed.

We have investigated the various nanotube (NT)-water complexes as important host-guest complexes via the DFT method using B3LYP/6-31G* and M06/6-31G* levels of theory. These NTs include single-walled and double-walled carbon nanotubes (SWCNT and DWCNT, respectively). In addition, the boron nitride nanotube (BNNT) and tip-functionalized CNTs are also designed. All geometries turn out as minima on their energy surfaces. Calculated structural and thermodynamic parameters, along with atoms in molecules (AIM) and natural bond orbital (NBO) analyses, indicate that water inside the SWCNTs shows a higher interaction with NT where the nature of interactions is partially electrostatic-partially covalent. Therefore, the SWCNTs turn out as the best candidates for carrying and storage the water molecules.
