Carbon nanotubes (CNTs) have great potential to improve the strength and toughness of traditional cementbased building materials. After effective dispersion in water with a surfactant, followed by separation using a centrifuge, multi-walled carbon nanotubes (MWCNTs) can be stored stably for over three...
This strength is due to the strong covalent bonds between the carbon atoms in the nanotube structure. These bonds allow the nanotubes to resist deformation and fracture under high stresses. Another important property of CNTs is their electrical conductivity. CNTs are excellent conductors of electricity...
The number of carbon nanotube layers dictates their name as well as their properties. CNTs come in different lengths (usually on the micron scale) as well as internal and external diameters (on the nano scale). Carbon Nanotubes Properties Carbon nanotubes are renowned for their excellent optical,...

(Phys.org) —Yale University researchers have developed a simple method for controlling the "doping" of carbon nanotubes (CNTs), a chemical process that optimizes the tubes' properties. Reported April 29 in Nano Letters, the method could improve the util
The networks were formed from the aqueous dispersion of MWCNTs or CNFs on the surface of the interdigitated electrode by a drop method. The obtained micrographs in Figure 3 show some differences, namely, the larger diameters of pores of CNF layer than the ones of the carbon nanotube layer....
Carbon nanotube-fused silica composite powders were synthesized by a sol-gel method, and then the composite powders were hot-pressed to obtain relatively dense composites. Complex permittivity spectra of these composites were obtained at 8-12GHz. The experimental results show that the complex permittiv...
Our ultimate goal is to control the optical properties of single walled carbon nanotube. To achieve our goal, we implemented density functional theory to study the effect of special types of Stone Wales defect, known as Haeckelite structure, on the optical properties of chiral nanotube. We also ...
We show that the thermal and electrical properties of single wall carbon nanotube (CNT)-polymer composites are significantly enhanced by magnetic alignment during processing. The electrical transport properties of the composites are mainly governed by the hopping conduction with localization lengths comparabl...
