Single-walled carbon nanotubes (SWCNTs) are formed by J.-K. Lee et al. from the spiral growth of graphene nanoribbons like an ivy vine growing on a tree. On page 3283, the helical structure addresses mounting inconsistencies in the measured mechanical and electrical properties of SWCNTs. The...

Single walled carbon nanotubes (SWCNTs) are one-dimensional structures with unique optical and electronic properties relevant for many biomedical applications1,2,3. Particularly, the sharp densities of electronic states at the so-called van Hove singularities (vHS) in SWCNTs impart strong resonant opt...
Despite the fact that methods of the synthesis of single-walled carbon nanotubes (SWCNTs) are well-established, they allow obtaining only mixtures of SWCNTs with different electronic properties. The development of approaches of controlling the electronic structure of SWCNTs opens a way to prepare ...
Carbon nanotubes1 are predicted to be metallic or semiconducting depending on their diameter and the helicity of the arrangement of graphitic rings in their walls2,3,4,5. Scanning tunnelling microscopy (STM) offers the potential to probe this prediction,
describe the optimization of parameters involved in the production of nanofibers. Single-walled carbon nanotubes were used to improve the mechanical properties. The results show that the concentration has a greater effect on the fiber diameter than other parameters in PAN and PAN/CNT nanofibers. ...
We present density functional theory and tight binding calculations of a radially deformed (8,0) single walled carbon nanotube under transverse external electric fields. Density functional theory calculations are also presented for radially deformed and defective (8,0) nanotube. Three types of single ...
ConspectusSingle-walled carbon nanotubes (SWNTs) have shown great potential in various applications attributed to their unique structure-dependent properties. Therefore, the controlled preparation of chemically and structurally pristine SWNTs is a crucial issue for their advanced applications (e.g., nano...
We report benchmark calculations of electroabsorption in semiconducting single-walled carbon nanotubes that provide motivation to perform electroabsorption measurement on these systems. We show that electroabsorption can detect the continuum bands in different energy manifolds. Direct determination of the binding...
We have examined the structure and function of two enzymes, α-chymotrypsin (CT) and soybean peroxidase (SBP), adsorbed onto single-walled carbon nanotubes (SWNTs). SBP retained up to 30% of its native activity upon adsorption, while the adsorbed CT retained only 1% of its native activity....
