Patterned growth of vertically aligned carbon nanotubes on pre-patterned iron/silica substrates prepared by sol-gel and shadow masking

Article Abstract:

The sol-gel technique is used to prepare film-like iron/silica substrates for the large-scale growth of highly aligned carbon nanotubes. By using transmission electron microscopy (TEM) grids as shadow masks, the sol-gel technique could be readily adapted to prepare patterned film-like iron/silica substrates, on which various kinds of micropatterns of vertically aligned carbon nanotubes could be fabricated.

Adsorption properties and structural characterization of activated carbons and nanocarbons

Article Abstract:

Morphologic and structural characterizations of samples of carbon nanotube porous materials by Brunauer, Emmett, And Teller method, transmission electronic microscopy is presented. A specific finding of this measurement estimates the excess adsorption, the relevant quantity for a correct determination of the storage capacity of porous materials.

Controlling the size of magnetic nanoparticles using pluronic block copolymer surfactants

Article Abstract:

The study successfully controlled the size of magnetic nanoparticles by adjusting the surfactant/solvent ratio. Gamma-Fe2O3 nanoparticles of 5.6 and 12.7 and Fe(super 0) nanoparticles of 22.3 nm in diameter were prepared, all having spherical shape and uniform size as confirmed by TEM.
