Question 7

In theory this can be produced from nearly any chemical.

Answer 7

Nanoparticles

Question 8

Epoxy containing carbon nanotubes are being used to make windmill blades.

Answer 8

Energy storage, production and conversion

Question 9

Nanosensors are important nanoproducts for faster detection of soil quality.This will also enable plant health monitoring for improved crop yield. Nanocapsules may also be developed for more efficient delivery of herbicides and drugs for livestock.

Answer 9

Agricultural productivity and enhancement; vector and pest detection and control

Question 10

Nanoparticles are useful in cleaning up organic chemicals/solvents polluting groundwater. The iron nanoparticles disperse throughout the body of water and decompose the organic solvent in place.

Answer 10

Water treatment and remediation

Question 11

Nanotechnology-based diagnostic kits for screening of diseases and systems of drug delivery will be very useful in health monitoring and cure.

Answer 11

Disease diagnosis and screening; drug delivery systems

Question 12

Nanotechnology is useful when nanocomposite-based film crating is used in food packaging.

Answer 12

Food processing and storage

Question 13

Generating less pollution during the manufacture of materials is very important. Researches have shown that the use of silver nanoclusters as catalysts can significantly reduce the polluting by-products generated in the process used to manufacture propylene oxide.

Answer 13

Air Pollution and remediation
