Nanocones- a different form of carbon with unique properties

Abstract

It is possible to make perfect conical carbon nanostructures fundamentally different from the other nanocarbon materials, notably buckyballs and nanotubes. Carbon cones are realized in five distinctly different forms. They consist of curved graphite sheets formed as open cones with one to five carbon pentagons at the tip with successively smaller cone angles, respectively. The nucleation and physics of nanocones has been relatively little explored until now. We present here the key facts and latest results on this “5’th form of carbon”.

Eccentricity‐based topological invariants of tightest nonadjacently configured stable pentagonal structure of carbon nanocones

“…[12, 13]. Motivation of subject paper comes from the fact that now it is conceivable to make consummate conical carbon nanostructures in a general sense extraordinary from the other nanocarbon structures, remarkably buckyballs and nanotubes [14]. Carbonic cones are acknowledged in distinct five extraordinary structures.…”

“…The nucleation and material science of nanocones has been investigated a little up till now. Furthermore, the motivation of article is from the fact that if the distance increasing between the pentagons then it leads to larger and more localized bond stress at the resulting cusps of cones [14]. More pentagons at the tip of cone gives more stable structures of chemical bonding.…”

“…In this article, two families of nanocones are considered and their ECI, TEI, and eccentricity‐based Zagreb index are computed. In future, we are interested to formulate the architectures of next complex structured nanocones with more pentagons at the tip of cones [14] and study their topological invariants, which could be quite helpful to understand their chemical structure and behavior.…”

Molecular Dynamics of Water Embedded Carbon Nanocones: Surface Waves Observation

“…They occur in single-and multi-walled formations with different apex angles. Their surface topology comprises regular hexagonal sp 2 carbon rings and 1-5 pentagonal rings concentrated near the apex [56][57][58][59]. CNCs were synthesised by accident in 1995 in the so-called Kvaerner Carbon Black & H 2 process, which decomposes hydrocarbons directly into carbon and H 2 [60,61].…”
