Spinning of carbon nanotube fibres using the floating ...

The CVD process for the spinning of carbon nanotube (CNT) fibres combines the nucleation, growth and aggregation of CNTs in the form of an aerogel with fibre spinning into a single process step. The optimisation of the process requires agility in multi-dimensional parameter space, so one tends to fi …

CaCo3 supported Co‐Fe catalysts for carbon nanotube ...

The synthesis of carbon nanotubes (CNTs) on a cobalt‐iron (Co‐Fe) catalyst supported on a calcium carbonate (CaCO 3) substrate, contained within a fluidized bed was investigated for the first time.CaCO 3 supported catalysts, prepared using traditional wet impregnation techniques result in a soft and sticky powder requiring special arrangements to ensure satisfactory fluidization.

Carbon nanotube transistors scaled to a 40 …

The formal challenge for high-performance transistors is to fit within ever smaller devices. They need to shrink from a lateral dimension of about 100 to 40 nanometers. Cao et al. fabricated tiny devices by using a single semiconducting carbon nanotubes, as well as arrays of these nanotubes. High performance (a high saturation on-state current >1.2 milliamperes per micrometer and a conductance ...
