Understanding Carbon Nanotubes

What is one of the potential applications of carbon nanotubes mentioned in the video?

• Creating biodegradable plastics

• Building a space elevator

• Developing solar panels

• Producing synthetic food

Why are carbon nanotubes not yet widely used in everyday electronics?

• They are too expensive to produce

• They are difficult to manufacture

• They are not strong enough

• They are not conductive

What role does the sputterer play in the production of carbon nanotubes?

• It mixes the carbon and iron

• It cools down the nanotubes

• It deposits iron seeds onto tungsten foil

• It heats the carbon atoms

What gas is used as a source of carbon in the nanotube growth process?

• Methane

• Oxygen

• Acetylene

• Nitrogen

How do carbon nanotubes grow during the production process?

• By being exposed to sunlight

• By cooling down rapidly

• By absorbing carbon from acetylene gas

• By being compressed under high pressure
