The new three-dimensional structure that the graphene connected with SWCNTs (G-CNTs, Graphene Single-Walled Carbon Nanotubes) can solve graphene and CNTs' problems. A comprehensive study of the mechanical and electrical performance of the junctions was performed by first-principles theory. There were eight types of junctions that were constituted by armchair and zigzag graphene and (3,3), (4,0)...

Introduction Nanocarbons have attracted worldwide attention in nanoscience and nanotechnology communities during the past two decade because of their unique mechanical and electrical properties, which make them great potential in catalysis, electrochemical devices, field emission devices and composites[1-2]. However, the high cost and low yield for production of these materials remains the bott...

Currently it is not fully understood how carbon nanotubes (CNTs) may affect human health. Despite this, CNTs are produced at a tonne mass scale yearly. Due to their large production and intended use within a variety of applications it is imperative that a clear understanding of the hazard potential of CNTs is gained. The aim of this study therefore was to assess the impact of five different ind...

The main challenge in the production of metal matrix composites reinforced by carbon nanotubes (CNTs) is the development of a manufacturing process ensuring the dispersion of nanoparticles without damaging them, and the formation of a strong bond with the metallic matrix to achieve an effective load transfer, so that the maximum reinforcement effect of CNTs will be accomplished. This research f...

BACKGROUND The production and use of carbon nanotubes (CNTs) is rapidly growing. With increased production, there is potential that the number of occupational exposed workers will rapidly increase. Toxicological studies on rats have shown effects in the lungs, e.g., inflammation, granuloma formation, and fibrosis after repeated inhalation exposure to some forms of multi-walled CNTs (MWCNTs). St...

Carbon nanotubes (CNT) have the potential to become an important component of scaffolding in tissue engineering, due to their unique physical properties. However, one major limitation of CNTs that must be overcome is their inherent cytotoxicity. In this study, we assessed the long-term biocompatibility of CNTs for chondrocyte growth. The effect of CNTs on chondrocyte viability and biochemical d...

Since Iijima discovered carbon nanotubes (CNTs) in 1991, many unique physical and electrical properties of CNTs have gradually been uncovered. CNTs have exceptionally high Youngâ€TMs modulus, stiffness and flexibility, and are electrically conductive with a greater diamagnetic susceptibility than graphite. Carbon nanotubes are pseudo-one-dimensional carbon allotropes of high aspect ratio, high ...
