Description:
In the catalysed growth of nanotubes and nanofibres, Energy Dipsersive X-ray (EDX) nano-analysis of individual metal particle compositions can be used to understand the relationships between catalyst particle size, composition and nanofibre form and diameter. The image shows TEM-EDX elemental analysis of individual metal catalyst particle compositions from a carbon nanofibre material. TEM visualisation combined with EDX characterisation of carbon nanotubes enables both process improvement and control in production of the nanotubes themselves (Copyright QinetiQ).
