Question

Carbon nanotubes are nanostructures:

• A. Zero-dimensional
• B. One-dimensional
• C. Two-dimensional
• D. Three-dimensional

Hint:

Carbon nanotubes have unique electronic, mechanical, and thermal properties, due to their unique 1D structure, allowing for various applications like high strength composites and efficient transistors.

Answer 1

The Correct Option is B

Carbon nanotubes (CNTs) are one-dimensional nanostructures, characterized by a length significantly exceeding their nanometer-scale diameter. Key characteristics include:
• Types: Single-walled (SWCNTs) and multi-walled (MWCNTs).
• Notable Properties: Exceptional tensile strength, electrical conductivity, and thermal stability.
• Uses: Applied across nanotechnology, electronics, and material science, encompassing energy storage and drug delivery.
Their 1D architecture confers unique physical and electronic attributes, making CNTs highly valuable in advanced applications.
