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...

Solar light driven photocatalytic degradation of methylene blue using carbon doped ZnO nanostructures.

Porous anodic alumina membranes (AAMs) have attracted great amount of attention due to their potential application as templates for nanoengineering. Template-guided fabrication and assembly of nanomaterials based on AAMs are cost-effective and scalable methods to program and engineer the shape and morphology of nanostructures and nanomaterials. In this work, perfectly ordered AAMs with the reco...

This paper describes an approach to the adsorption phenomena modeling aimed at specifying the adsorption mechanisms on localized or nonlocalized adsorbent sites, when applied to the nanocarbons. The concept comes from the fundamental thermodynamic description of adsorption equilibrium and is based on numerical calculations of the hydrogen adsorbed particles volume on the surface of selected nan...

The diamond or graphene lattices may be expanded theoretically by replacing one or several CC bonds of each carbon atom by the sequence C−(C≡C)k−C with k = 1, 2, etc. In this communication a systematic approach is described, by operating these replacements according to the four directions around an sp-hybridized carbon atom (affording “mdirectional diamond-yne”) with m = 1 to 4 or the three dir...
