Growing clean carbon nanotubes

Materials World magazine
Using catalysed chemical vapour deposition, scientists at the University of Warwick, UK, have grown clean carbon nanotubes directly onto a disc surface. The creation of these ultramicroelectrodes, which are 25-100µm in diameter, could be used for extremely sensitive sensors.

New smelter could save energy

Materials World magazine
Following the acquisition of Alcan last year, Rio Tinto has announced the evolution of Alcan’s aluminium production technology through a smelting process that consumes up to 20% less energy. The system, which is based on heat recovery, low resistance cathode blocks and drained cathodes, will be scaled up in 2009 at the company’s pilot plant in St Jean de Maurienne, France.
