The results of hydrogenation of single walled carbon nanotubes (SWCNTs)-SnO2 composite thin film is reported here. SWCNTs mixed with SnO2 by weight are made into pellet without any binder. Then, the pellet is evaporated by electron beam on glass substrates at room temperature in hydrogen atmosphere. The amount of hydrogen incorporated in the SWCNTs-SnO2 composite is found to be 2.4 wt.%. In add...

Direct laser writing through two-photon polymerization lithography is used to fabricate 3D nanostructures containing aligned single-wall carbon nanotubes (SWCNTs). SWCNTs are aligned in the laser scanning directions while they are embedded in the structure. The alignment is induced by spatial confinement, volume shrinkage, and the optical gradient force. This method is expected to lead to new a...

Herein we report on the facile preparation of brominated SWCNTs based on two complementary reductive activation routes. The respective brominated SWCNTs are highly reactive and can be used in nucleophilic substitution reactions and represent versatile starting materials for the generation of sidewall functionalized SWCNTs with a high density of functional moieties.

We report on hybrids of water-soluble calix[8]arenes and single-walled carbon nanotubes (SWCNTs); the hybrids formed supramolecular SWCNTs network polymer by adding guest dimer.

Light harvesting nanostructure hybrids have been designed and demonstrated using single-wall carbon nanotubes (SWCNTs) and porphyrin chromophores. DNA oligonucleotides are used to conjugate SWCNTs with light-absorbing chromophores for transparent films which generate photocurrents. High-purity semiconducting SWCNTs demonstrate significant enhancement in the photocurrent compared to metallic or ...

Single-walled carbon nanotubes (SWCNTs) have attracted great interest in the last two decades because of their unique electrical, optical, thermal, mechanical properties, etc. One major research field of SWCNTs is the controlled growth of them from the patterned catalysts on substrates, since the integration of SWCNTs into nanoelectronics and other devices requires well-organized SWCNT arrays. ...

Tip-enhanced Raman scattering (TERS) has emerged as a powerful analytical tool for measuring chemical images with nanometre spatial resolution. In this paper, the application of TERS to study differentiation of single-walled carbon nanotubes (SWCNTs) with 14 nm spatial resolution is demonstrated by the measurement of a mixture of two different types of SWCNTs as the model sample. The results de...

This paper discusses the fundamental issues of the elastic properties and effective wall thickness of single-walled carbon nanotubes (SWCNTs). It provides an in-depth analysis based on the rationale of the nanoscale-to-macroscale deformation relationship of SWCNTs and carries out a critical assessment of the diverse theoretical predictions in the literature. It was found that the in-plane stiff...

BACKGROUND Carbon nanotubes are increasingly being tested for use in cellular applications. Determining the mode of entry is essential to control and regulate specific interactions with cells, to understand toxicological effects of nanotubes, and to develop nanotube-based cellular technologies. We investigated cellular uptake of Pluronic copolymer-stabilized, purified ~145 nm long single wall c...

In this paper, single wall carbon nanotube (SWCNT) suspensions were added dropwise to silica particles before volatising the solvent to prepare a core-shell composite adsorbent with SWCNTs wrapped around silica particles (SWCNTs@Silica). The composite adsorbent was used as packing for the solid phase extraction (SPE) and the enrichment of organophosphorus pesticides (OPPs) in water. The results...
