Material World: Carbon nanotubes take new shape

Wondrous World of Carbon Nanotubes

Wondrous World of Carbon Nanotubes

Carbon nanotubes are generally produced by three main techniques, arc discharge, laser ablation and chemical vapour deposition. Though scientists are researching more economic ways to produce these structures. In arc discharge, a vapour is created by an arc discharge between two carbon electrodes with or without catalyst. Nanotubes self-assemble from the resulting carbon vapour. In the laser ab...

relation of material world to dahr world: a new interpretation

in this paper, we try to determine the status of the relation between dahr world and matrial world. the conclusion shows the subjective duality and objective unity of dahr and material entities. two interpretations of this duality can be suggested. in the first interpretation, this unity, and the duality supposed, are explained on the basis of different intellectual cognition of immaterial and ...

Monolithic microcavity with carbon nanotubes as active material

Carbon Nanotubes As A Premium Catalyst Support Material

Carbon nanotubes are a special carbon material having a highly graphitic nature and nanoscale dimensions. These tubular filaments were first observed from steam cracker when electron microscopes came into wide use around 1950s [1], however, intentional synthesis of carbon nanotubes in bulk quantity wasn’t successful till 1983 [2]. Without formal presentation, this invention was mostly unknown t...
