Q. Consider the following statements about the classification of nano-materials:
1. Zero Dimensional Nano-materials are those that have all their dimensions less than 100nm.
2. The nano-film is an example of one-dimensional nano-material.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A
Notes:

Classification of Nanomaterials

Nanomaterials can be classified on the basis of their dimensions into the following categories:

  • Zero Dimensional Nanomaterials (0D):These nanomaterials have all the dimensions within the nanoscalee. no dimensions are larger than 100 nm. Most commonly, 0D nanomaterials are nanoparticles.
  • One Dimensional Nanomaterials (1D):These have one dimension outside the nanoscale. This class includes nanotubes, nanorods, and nanowires.
  • Two Dimensional Nanomaterials (2D):These have two dimensions outside the nanoscale. This class exhibits plate-like shapes and includes graphene, nanofilms, nanolayers, and nanocoatings.
  • Three Dimensional Nanomaterials (3D):These are materials that are not confined to the nanoscale in any dimension. This class can contain bulk powders, dispersions of nanoparticles, bundles of nanowires, and multi-nanolayers.
