A novel approach to fabricate highly graphitic carbon nanostructures such as carbon nanotubes (CNTs), metal/graphitic-shell nanocrystals and hollow carbon nanospheres (HCNSs) in a very short time is demonstrated.

This review paper provides researcherwith a comprehensive information about the Carbon Nano tubes and the catalyst parameters that influences theproduction and morphology of the of Carbon Nano tubes.Carbon nanotubes, referred to as CNTs, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. Since discovery of CNTs in 1991, many scienti...

There are similarities between microtubules in living cells and carbon nanotubes (CNTs). Both microtubules and carbon nanotubes have a similar physical structure and properties and both are capable of transporting information at the nanoscale. Microtubules and carbon nanotubes can also self-organize to create random graph structures, which can be used as communication networks. The behavior of ...

Electrophoretic process was applied to the deposition of carbon nanotubes on the surface of carbon fabrics in order to enhance the properties of CNT/carbon fabric hybrid composites. Carbon fabrics were modified by two methods: Cu deposition by cathodic method and Cu coating by thermal vaporization method. CNTs were modified by PEI and oxidation treatment. The effects of carbon fabric and CNTs m...

Chemical Vapor Deposition (CVD) is one of the most popular methods for producing Carbon Nanotubes (CNTs). The growth rate of CNTs based on CVD technique is investigated by using a numerical model based on finite volume method. Inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal CVD reactor at atmospheric pressure. In thi...

Carbon monofluoride (CFx) has a high energy density, exceeding 2000 W h kg(-1), yet its application in primary lithium batteries is limited by its power capability. Multi-walled carbon nanotubes (CNTs) are appealing additives for high-power batteries, due to their outstanding electronic transport properties, high aspect ratio necessitating low volume fraction for percolation, and high tensile s...

in this study, bio-based carbon nanotubes (cnts) have received considerable research attention due to their comparative advantages of high level stability, simplistic use, low toxicity and overall environmental friendliness. new potentials for improvement in heat transfer applications are presented due to their high aspect ratio, high thermal conductivity and special surface area. phonons have ...

Carbon nanotubes are ideal scaffolds for designing and architecting flexible graphite films with tunable mechanical, electrical and thermal properties. Herein, we demonstrate that the assembly of aligned carbon nanotubes with different aggregation density and morphology leads to different mechanical properties and anisotropic electrical conduction along the films. Using drying evaporation under...

Effects of various factors affecting the rate of Carbon Nanotubes (CNTs) produced in a Swirled Floating Catalyst Chemical Vapour Deposition (SFCCVD) reactor were investigated. This study was performed in a vertical silica tube plug flow reactor developed by Iyuke at this University. Transmission Electron Microscopy (TEM) images revealed that both Single–Walled and Multi–Walled Carbon Nanotubes ...

A novel strategy for the fabrication of multiwall carbon nanotube-nanocrystal heterostructures is shown. Different quantum dots (QDs) with narrow size distributions were covalently coupled to carbon nanotubes (CNTs) and silica-coated CNTs in a simple, uniform, and controllable manner. The structural and optical properties of CNT/QD heterostructures are characterized by electron microscopy and p...
