A Theoretical Model of Laser Heating Carbon Nanotubes

Carbon nanotubes (CNTs) are allotropes of carbon, which have a cylindrical nanostructure with an exceptionally high aspect ratio where carbons are sp2 hybridised with three neighbouring atoms resembling a graphitic structure. Carbon nanotubes have the potential to be used as semiconductors, for example, potentially replacing silicon in a wide variety of computing devices. Nanotubes can be characterized by their number of concentric cylinders, cylinder radius and cylinder length. Some nanotubes have a property called chirality, an expression of longitudinal twisting.

Carbon nanotubes (CNTs) are usually delivered into the lungs of laboratory animals by inhalation, instillation or aspiration.No systemic toxicity of multi-walled carbon nanotubes (MWCNTs) could be observed in an inhalation study of several weeks with rats [2]. Carbon nanotubes are allotropes of carbon with a tube shaped nanostructure. They are generally referred as CNTs in short. Nanotubes are developed with a length-to-width proportion of up to 132,000,000:1. Carbon nanotubes are composed of carbon atoms linked in hexagonal shapes, with each carbon atom covalently bonded to three other carbon atoms. Carbon nanotubes have diameters as small as 1 nm and lengths up to several centimeters.

Single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) are similar in certain respects but they also have striking differences. SWNTs are an allotrope of sp2 hybridized carbon similar to fullerenes.

Flexible Multifunctionalized Carbon Nanotubes-Based Hybrid

Abstract: The unique properties of carbon nanotubes (CNTs) (such as their high surface to volume ratios, enhanced conductivity and strength, biocompatibility, ease of functionalization, optical properties, etc.) have led to their consideration to serve as novel drug and gene delivery carriers. Synthesis of carbon nanotubes by chemical vapor deposition over patterned catalyst arrays leads to nanotubes grown from specific sites on surfaces. The growth directions of the nanotubes can be controlled by van der Waals self-assembly forces and applied electric fields. Carbon nanotubes (CNTs) are a one-dimensional form of carbon.
