C2- Nanotechnology
Flashcards do conjunto (6)
- 1What is nano technology used for?For making and using nano particles.
- 2What can it help understand?The structures of bonds and molecules.
- 3How are nano particles produced? Give examples.Naturally- Seaspray uses nanoscale salt particles which are present in the atmosphere.
Accident- when fuels combust nanoscale soot particles are produced.
Using nanotechnology. - 4Give an example of how nano particles are used in particles.They modify the plastics and make the plastic stronger, more durable BUT they do not add any weight.
- 5What are silver nano particles?small polymer fibres which are used in surgical masks and wound dressings.
Giving them antibacterial properties- killing bacteria. - 6How are nano particles different to normal particles?1. They are a lot smaller.
2. They are the same material and they have a larger surface area-to-volume ratio. Which gives them different properties completely.
