Carbon nanocones: wall structure and morphology.
Large-scale production of conical carbon nanostructures is possible through pyrolysis of hydrocarbons in a plasma torch process. The resulting carbon cones occur in five distinctly different forms, and disc-shaped particles are produced as well. The structure and properties of these carbon cones and discs have been relatively little explored until now. Here we characterize the structure of thes...
متن کاملGraphene structure in carbon nanocones and nanodiscs.
Carbon nanoparticles, like nanocones and nanodiscs, can be obtained by mechanical treatment of carbon nanofilaments. Microstructural studies suggest that in nanocones the conical graphene stacking with progressively increasing apex (cone) angles does not fully agree with current theoretical geometry models, such as a closed cones model and a cone-helix model. The unusual stacking form of nanoco...
متن کاملBundlet Model for Single-Wall Carbon Nanotubes, Nanocones and Nanohorns
This paper discusses the existence of single-wall carbon nanocones (SWNCs), especially nanohorns (SWNHs), in organic solvents in the form of clusters. A theory is developed based on a bundlet model describing their distribution function by size. Phenomena have a unified explanation in bundlet model in which free energy of an SWNC, involved in a cluster, is combined from two components: a volume...
متن کاملCluster Nature of Single-Wall Carbon Nanocones and Nanohorns
It is discussed the existence of single-wall carbon nanocones (SWNCs), especially nanohorns (SWNHs), in organic solvents in the form of clusters [1]. A theory is developed based on a bundlet model, describing their distribution function by size [2]. The phenomena have a unified explanation in the bundlet model, in which the free energy of an SWNC, involved in a cluster, is combined from two com...
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...
