Chem 1, 531–556, October 13, 2016 In this review, we survey the role of carbon-based nanomaterials in energy-conversion schemes. In particular, we highlight charge-transfer processes on the molecular scale in sp2 carbon in zero dimensions (fullerenes), sp2 carbon in one dimension (carbon nanotubes), sp2 carbon in two dimensions (graphene), and sp2/sp3 carbon in zero and two dimensions (defectuous carbon nanostructures). As such, we conclude that the versatility of carbon-based nanomaterials in terms of structural and…"V. Strauss, A. Roth, M. Sekita, D.M.

Graphene and single-walled carbon nanotubes are carbon materials that exhibit excellent electrical conductivities and large specific surface areas. Theoretical work suggested that a covalently bonded graphene/single-walled carbon nanotube hybrid material would extend those properties to three dimensions, and be useful in energy storage and nanoelectronic technologies. Here we disclose a method to bond graphene and single-walled carbon nanotubes seamlessly during the growth stage. The hybrid material exhibits a surface area 42,000m2 g1 with ohmic contact…"Yu Zhu, Lei Li, Chenguang Zhang, Gilberto Casillas, Zhengzong Sun, Zheng Yan, Gedeng Ruan, & etc. A seamless three-dimensional carbon nanotube graphene hybrid material"
On the basis of ab-initio simulations, the value of strength of interatomic bonds in one-, two- and three-dimensional carbon crystals is obtained. It is shown that decreasing in dimensionality of crystal gives rise to nearly linear increase in strength of atomic bonds. It is ascertained that growth of strength of the crystal with a decrease in it dimensionality is due to both a reduction in coordination number of atom and increase in the angle between…"S.

Ab-initio calculations within Density Functional Theory combined with experimental Raman spectra on cluster-beam deposited pure carbon films provide a consistent picture of sp-carbon chains stabilized by sp3 or sp2 terminations, the latter being sensitive to torsional strain. This unexplored effect promises many exciting applications since it allows one to modify the conductive states near the Fermi level and to switch on and off the on-chain π-electron magnetism.
