How Carbon Nanotubes Are Made and How Carbon

Following milling, the powder is annealed under a nitrogen (or argon) gas flow at temperatures of 1400C for six hours. The mechanism of this process is not known, but it is thought that the ball milling process forms nanotube nuclei, and the annealing process activates nanotube growth.

Carbon nanotubes what they are, how they are made, what

Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) or multi-walled (MWCNT), consisting of several concentrically interlinked nanotubes.

Fullerene Wikipedia

A fullerene is an allotrope of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes, also referred to as Buckminsterfullerenes or buckyballs, resemble the balls used in association football. Cylindrical fullerenes are also called carbon nanotubes (buckytubes).

Effect of high-energy ball milling on morphology and field

The effects of grinding for different time in a vibrating mill with the mixture of Fe powder and multi-walled carbon nanotubes (MWNTs) were studied. The morphology and structure of as-ground MWNTs were carried out by X-ray diffraction (XRD) and High-resolution transmission electronic microscopy (HRTEM).

Influence of Surface Oxides on the Adsorption of

As greater quantities of carbon nanotubes (CNTs) enter the environment, they will have an increasingly important effect on the availability and transport of aqueous contaminants. As a consequence of purification, deliberate surface functionalization, and/or exposure to oxidizing agents after release to the environment, CNTs often contain surface oxides (i.e., oxygen containing functional groups).
