Cluster Origin of Solvent Features ficiency and interaction-energy parameters of nanohorns are the closest to the ones of nanotube clusters. The most nanotube-like behaviour is observed, and the properties of nanohorns are calculated the closest to the ones of nanotubes. The large structural asym- metry in the different types of nanocones, entirely characterized by their number of pentagons in one­five, allows distinguishing the calculated properties of some kinds es- pecially the cone with two pentagons. Work is in progress on the possible generalization of the conclusions above to more complex systems, e.g., single-wall boron nitride (BN) nanocones. Agustí, G., Cobo, S., Gaspar, A.
