Diamond fibres were fabricated using hot filament chemical vapour deposition (CVD) with tungsten wire of varying diameters as the cores. A steady-state technique was used to measure the thermal conductivity along the length of the individual fibres o

Diamond nanocrystals have been produced by the pulsed laser ablation of graphite at room temperature and pressure in two liquids (water and cyclohexane). This suggests that the mechanism for diamond formation maybe a result of the high-pressure, high
