Question

Explain any two applications of nanomaterials.

Explain the applications of nanomaterials.

Answer 1

1. Nanoparticles can contribute to stronger, lighter, cleaner and smarter surfaces and systems. They are used in the manufacturing of scratchproof eyeglasses, transport, sunscreen, crack resistant paints and so on.
2. Used in electronic devices. For example, Magnetoresistive Random Acess memory (MRAM).
3. Nanotechnology plays an important role in water purification techniques. Water contains waterborne pathogens like - viruses, bacteria. 1.1 billion people are without access to an improved water supply. The provision of safe drinking water is currently high priority. Recently, cost effective filter materials coated with silver nanoparticles (AgNps) is an alternative technology. (For example: water purifier) Silver nanoparticles act as highly effective bacterial disinfectant, remove E.Coli from water.
4. Self cleaning materials: Lotus is an example of self cleaning. The lotus plant (Nelumbo nucifera) although grows in muddy water, its leaves always appear clean. The plants' leaves are superhydrophobic. Nanostructures on lotus leaves repel water which carries dirt as it rolls off. Lotus effect is the basis of self cleaning windows.
