Researchers have used carbon nanofibres to separate components of a highly sensitive explosive system to make it much safer to use.
Nanothermites are versatile systems composed of a metal oxide and a reducing metal powder such as aluminium. The two components react in a very exothermic reaction, meaning the systems have potential applications as propulsion for rockets, explosives, or as pyrotechnic initiators. However, the mixtures are very sensitive so are difficult to handle in the lab, transport and integrate into systems that are going to be deployed elsewhere safely. More...
