antimatter Posted March 15, 2008 Posted March 15, 2008 Can someone explain to me how those two are formed naturally? I know what they are, it's just how they are formed in nature baffles me.
antimatter Posted March 15, 2008 Author Posted March 15, 2008 Carbon nanotubes, sorry for not stating that clearer
antimatter Posted March 15, 2008 Author Posted March 15, 2008 I think that pressure has something to do with it take a look at the image, it's so compacted... I think pressure is a major factor
thedarkshade Posted March 15, 2008 Posted March 15, 2008 Can someone explain to me how those two are formed naturally?On earth they are artificial allotropic modifications, but I think scientist managed to find them on some meteors. Care to share a link? 1
antimatter Posted March 16, 2008 Author Posted March 16, 2008 Are you sure it's not made on Earth? I think they're natural allotropes
Klaynos Posted March 16, 2008 Posted March 16, 2008 http://en.wikipedia.org/wiki/Carbon_nanotube#Natural.2C_incidental.2C_and_controlled_flame_environments One of my friends once explained to me how he makes carbon nanotubes in his lab, but I can't remember much more than it's REALLY annoying to make graphine... (monolayer graphite)
antimatter Posted March 16, 2008 Author Posted March 16, 2008 These are all carbon allotropes though, right?
thedarkshade Posted March 16, 2008 Posted March 16, 2008 Carbon's natural allotropies are diamond and graphite, and fulleren is artificial. With fulleren we understand molecules which can contain from tens to hundreds of carbon atoms. The most stable is considered Buckminster fulleren, made up of 60 C atoms, forming so pentagons and hexagons. The name buckminster fulleren was given due to the philosopher and architect Buckminster Fuller! There is the amorphous carbon too, but that is not considered as a typical alloptropy due to not being 100% carbon!

antimatter Posted March 16, 2008 Author Posted March 16, 2008 you can get other allotropes from fire... I heard that somewhere too, I'm just not entirely sure of the process
