Identify a zero dimensional nano structure from following

Identify a zero dimensional nano structure from following
  1. Nanorods
  2. Nanoparticles
  3. Thin films
  4. Fibres

Solution

(1) Nanorods: 1D structure: Elongated in one dimension (length), confined in the other two (width and height). (2) Nanoparticles: OD structure: No elongation in any dimension, confined in all directions (usually spherical). (3) Thin films: 2D structure: Thin in one dimension (thickness) but extends in the other two (length and width). (4) Fibres: 1D structure: Elongated in one dimension (length), confined in the other two.
