Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Carbon nanotube?1991
2. What is the classification?Single-walled nanotubes (SWCNTs) and multi-walled nanotubes (MWCNTs)
3. What is the young's modulus?Approximately 1-2 TPa
4. Why are carbon nanotubes so strong?The carbon atoms are bonded in a special pattern that makes the tubes very stiff and strong, even though they are very light.
5. How are carbon nanotubes made?Scientists use methods like arc discharge, laser ablation, or chemical vapor deposition to grow the tubes, with the last one being common for large production.

Allotrope: Different structural forms of the same element in the same physical state, like diamond and graphite for carbon.
Chirality: The property of a molecule that is non-superimposable on its mirror image, affecting CNT electronic properties.
Chemical Vapor Deposition (CVD): A manufacturing process used to produce high-quality, high-performance solid materials, typically in thin film form.
