NANOCONES - A Classification Result in Chemistry
نویسندگان
چکیده
Nanocones are carbon networks situated in between graphite and the famous fullerene nanotubes. Graphite is a planar carbon network where each atom has three neighbours and the faces formed are all hexagons. Fullerene nanotubes are discussed in two forms: once the finite, closed version where except for hexagons you have 12 pentagons and once the one-side infinite version where 6 pentagons bend the molecule so that an infinite tube with constant diameter is formed. A nanocone lies in the middle of these: it has between 1 and 5 pentagons besides the hexagons, so that neither the flat shape of graphite nor the constant diameter tube of the nanotubes can be formed. Recently the attention of the chemical world in nanocones has strongly increased. Figure 1 shows an overview of these types of carbon networks.

Computational studies of carbon decorated boron nitride nanocones
Density functional theory ,(DFT) calculations have been performed to investigate the properties ofcarbon decorated (C-decorated) models of boron nitride (BN) nanocones. To this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the C-decorated models. Theresults indicated that dipole moments and energy gaps could reveal the effects of C-decorations onthe pro...
متن کاملMetallopyrrole-capped carbon nanocones.
We design nickel-doped and nitrogen-doped carbon nanocones with various amounts of buckling that feature square-planar, (approximate) tetrahedral, and octahedral coordination. The optimized geometries and electronic structures of these novel metallocarbon complexes are calculated by using the B3LYP (Gaussian03) and GGA-BLYP (ADF) exchange-correlation functionals. We analyze buckling and stabili...
متن کاملFlexoelectricity in Carbon Nanostructures: Nanotubes, Fullerenes, and Nanocones.
We report theoretical analysis of the electronic flexoelectric effect associated with nanostructures of sp(2) carbon (curved graphene). Through the density functional theory calculations, we establish the universality of the linear dependence of flexoelectric atomic dipole moments on local curvature in various carbon networks (carbon nanotubes, fullerenes with high and low symmetry, and nanocon...
متن کاملElectron states in boron nitride nanocones
We apply first-principles calculations to study the electronic structure of boron nitride nanocones with disclinations of different angles θ = nπ/3. Nanocones with odd values of n present antiphase boundaries that cause a reduction of the work function of the nanocones, relative to the bulk BN value, by as much as 2 eV. In contrast, nanocones with even values of n do not have such defects and p...
متن کاملYoung s Modulus of Single and Double Walled Carbon Nanocones Using Finite Element Method(TECHNICAL NOTE)
In this paper a three-dimensional finite element (FE) model of carbon nanocones (CNCs) is proposed and used for obtaining Young\'s modulus of CNCs. In this model, stretching and bending forces between carbon atoms are simulated using truss elements in ANSYS software. Then the model is subjected to the tension and by obtaining the stiffness of the CNC and using elasticity theory, Young’s modulus...
