Question

Which is the most important property of Nano-materials?

Answer 1

Friction at nano-scale:

1. Nanomaterials can be defined as materials possessing minimum dimensions measuring 1-100 nanometers.
2. Friction is the force that resists the initiation of sliding or any type of motion between two surfaces. Nano-materials have an enormous surface-to-volume ratio that leads to severe friction and thus wear and tear issues.
3. Hence friction is an important property to consider to increase practical benefits and lifetime. Friction is the main factor limiting the efficiency of nano-fluid devices (where fluids are confined to the nano-scale).

1. Friction is the most important property of nano-materials. At the nano-scale different processes contribute to energy losses during sliding and thus lead to friction. Hence, friction becomes more complicated and important.
2. Nano-materials are special for several reasons, but for one in particular – their size. Nanomaterials are up to 10,000 times smaller than the width of one strand of human hair. Nano-particles have a very high surface area to volume ratio.
