Electric cables heat up because of resistance. When the current load exceeds the cable?s safe capacity, they get too hot and break. The researchers found nanotube fibers exposed to nitrogen performed best, followed by argon and open air, all of which were able to cool through convection. The same nanotube fibers in a vacuum could […]
Carbon fiber is widely used nowadays for different applications. This fiber consists of billions of carbon nanotubes oriented in the same direction. It is stronger than steel and has greater electrical conductivity. Such properties of carbon fibers as high stiffness, fire proof, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low […]
A carbon nanotube is a nano-size cylinder of carbon atoms. Imagine a sheet of carbon atoms, which would look like a sheet of hexagons. If you roll that sheet into a tube, you’d have a carbon nanotube. Carbon nanotube properties depend on how you roll the sheet. In other words, even though all carbon nanotubes […]
