Materials which pack in the form of small rod shapes are of technological interest since they can exhibit considerable strength. In the past decade, we have seen an enormous level of activity in nanostructured materials, fuelled in particular by carb

The heterogeneity of the web by changing the ratio of cobalt to graphitic carbon in the reaction mixture is investigated. The various webs were studied by electron microscopy and micro-Raman spectroscopy. It is shown that structures in the web have v

Sodium hydroxide is used at elevated temperatures to separate aluminum hydroxide from ferric oxide (red mud) in bauxite in the Bayer process. Organic material in the bauxite can intefere with the precipitation of aluminum hydroxide. In this paper we

The size distribution of soluble copper complexing ligands ( 14,000 Dalton fraction. As the majority of soluble iron was also associated with this fraction, it is likely that this complexing pool contains organic ligands adsorbed to the surface of in

Graphite has normally been used to synthesise fullerenes and nanotubes. However, coal is a cheaper and more suitable industrial material. Because coal is a molecular solid, unlike graphite, the mechanism by which fullerene and nanotubes are formed is
