Gas phase production of single-walled carbon nanotubes
… have been produced in a continuous flow gasphase catalytic growth process, in a heated flow of carbon monoxide at pressures of 1--10 atmospheres and temperatures of 800--1200°C. Catalytic cluster nuclei for the nanotubes are generated in situ by thermal decomposition of iron pentacarbonyl. The …

Analysis of potential applications for the templated dewetting of metal thin films
… media, plasmon waveguides, and catalytic growth of ordered arrays of semiconducting nanowires and carbon nanotubes are discussed. Templated dewetting technology has not been fully developed, and technological barriers are identified for all of the commercial applications …

Growth and characterization of ZnO and related nanostructures
… nanostructures and the understanding of growth morphology are described. By using a simple vapour phase transport (VPT) and condensation process, we have grown low dimensionality ZnO nanostructures on a-plane sapphire with gold (Au) catalyst. The catalytic growth of various nanostructures …

The Use of Secondary Ion Mass Spectrometry to Advance Integrated Process Technology for 2D Materials
… contaminants can significantly influence the catalytic growth process, as well as the post-growth processing, and can be deleterious for many applications. There is a need for characterisation techniques with very high elemental resolution combined with surface sensitivity and suitably high …

Heavy-metal-free colloidal nanocrystal heterostructures – synthetic chemistry and growth mechanisms
… understanding of the synthetic chemistry and the growth mechanisms for heavy-metal-free nanocrystal heterostructures is critical before their commercialization potential becomes reality. Here, we have developed novel synthetic strategies to achieve the anisotropic growth of colloidal nanocrystals …
