The Applications Of Nanoparticles

Question 1

How can nanoparticles be used in glass?

Answer 1

Glass can be coatedwith titanium oxide nanoparticles. This cleans the windows automatically

Question 2

How can nanoparticles be used in sunscreen?

Answer 2

Titanium oxide and zinc oxide are coated in silica. These coated nanoparticles are more effective at blocking the Sun’s rays

Question 3

How can nonoparticles be used in cosmetics?

Answer 3

The nanoparticles in creams are absorbed deeper into the skin

Question 4

How can nanoparticles been used in the future

Answer 4

Nanotubes are now being develepode that can be used as this will make it possible to construct incredibly small electronic circuits

Question 5

Nano tubes can now be developed as nanowires, this can make it possible to construct…

Answer 5

Incredibly small electronic circuits

Question 6

Why will the nanoparticles make very good catalysts?

Answer 6

Because they have a large SA:V ratio

Question 7

Nanowires would also help to make…

Answer 7

Computers with vastly improved memory capacities and speeds

Question 8

What si a possible risk of nanoparticles?

Answer 8

Their large surface area makes them dangerous. If a spark is made by accident near a large quantity of the catalyst, there could be a violet explosion.

Also, if nonaparticles are used more and more, there is also going to be more risk of them finding their way into the atmosphere. Scientists believe that the health hazard increases as the diameter of the particled decreases. Breathing in tint particles could damage the lungs.
