CVD synthesis of nitrogen doped carbon nanotubes using iron pentacarbonyl as catalyst

Ghadimi, Nafise (2012-02-24)

In this dissertation, the synthesis of nitrogen doped carbon nanotubes (N-CNTs) was performed successfully, using a floating catalyst chemical vapour deposition (CVD) method. Fe(CO)5 was utilized as the catalyst and ...
Optical properties of vanadium oxide nanostructures synthesized by laser pyrolysis

Shikwambana, Lerato David (2012-02-28)

In this work, the primary investigation has been on the development of the laser pyrolysis setup and its optimization for the synthesis of nano-size VO2-x films. More specifically the focus was on making VO2-x depositions ...
Synthesis of Tungsten Oxide Nanostructures by Laser Pyrolysis

Govender, Malcolm (2012-02-01)

This dissertation discusses the synthesis method known as laser pyrolysis. The theory on laser pyrolysis has been inferred since 1975, but it is insufficient in predicting the products that can be formed. This is due to ...
