We do not see objects or measure distances in the nanoscale in our daily life. Comprehension of the nanoscale (a very very small scale) is only possible with fun examples resembling nanoscale.
Making Origami Buckyball
A buckyball is a molecule containing 60 carbon atoms. Each carbon atom is bonded to three adjacent carbon atoms, and the entire grouping forms a sphere. This unique molecular shape and composition is useful in many of applications.
Research on nanocrystalline materials has increased enormously during the past years. The intense investigations are stimulated by several envisaged application areas for this new class of materials. For example, the novel optical, electrical, and mechanical properties of devices comprising nanocrystallite semiconductors and oxides have been demonstrated in photovoltaic solar cells, light-emitting diodes, varistors, and ceramics. Other applications include ion insertion batteries and electrochromic devices.
The lotus effect refers to the very high water repellence exhibited by the leaves of the lotus flower. Dirt particles are picked up by water droplets due to a complex micro- and nanoscopic architecture of the surface, which minimizes adhesion. Some nanotechnologists have developed treatments, coatings, paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves in the same way as the lotus leaf.
Iron Nanoparticles and Ferrofluids
Nanoscale iron particles are sub-micrometer particles of iron metal. They are highly reactive because of their large surface area. In the presence of oxygen and water, they rapidly oxidize to form free iron ions. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in an organic solvent or water.
