C4 nanoparticles
Karten in diesem Stapel (7)
- 1What is nm in standard form?1 x 10^-9
- 2How big are nano particles?have a diameter between 1nm and 100nm
- 3Why are the properties of material in bulk different to the properties when its in nanoparticle form?The nanoparticle's large SA:V means a higher proportion of atoms are at the surface and are able to interact with the substances than in the bulk material.
- 4What are fullerenes?a form of carbon. They're large molecules shaped like hollow balls or tubes. They're arranged in rings
- 5what are the properties of fullerenes?pretty high MPs and BPs for molecular substances
- 6What are some uses of nanoparticles?catalyst (due to high SA:V)
can cage and deliver drugs when absorbed into the body
molecular sieves
lubricant coating
electric circuits
antibacterial would dressings - 7What are the fears of nanotechnology?That they're so small, that when they're absorbed, they could react in unknown ways to cause side-effects
