what is a Nanotube, apart from something dusty waving in wind ?... and if they cant reproduce how come there are more than one ?

WTF? It's alive?

Maybe. It is carbon based like us, but it can't repoduce.

Really... A carbon nanotube is carbon based... I never would've guessed... lol, I just think it's weird how its moving, so like, yeah. Not the vibrating, thats just temperature, I mean how it's twitching.

@flutist001 maybe this kind of random motion was very important for the first aminoacids

@Xxero0 Actually, I think it has something to do with the wind. If you blow on a desk, for example, a Rubik's cube won't go very far. But smaller, lighter things, like small sheets of paper will move.
Now, we're looking at something so insanely tiny and light, that is must be able move in practically no wind at all, like in a room.
Sounds like something only a science enthusiast would know, I know. But it actually is quite simple.

wait, that thing has a diameter of what?

In fact I only observe them by field emission microscopy so I cannot tell you if they look like spaguetti ;) But I will try soon to observe them by SEM/HRTEM

Very impressive!Have you published that?I'm myself trying to grow CNTs in situ on the extremity of sharp Ni tips and it's really complicated!
matiak2000 4 years ago
No, there are a few labs published mounting single nanotube on tungsten or nickel tips already. See a recent paper in J. Vac. Sci. Technol. B 25(2) Mar/Apr 2007 (under EXPERIMENT on page 561).
Did your nanotubes look like spaghetti when you grow them on Ni tip?

Can I ask you some questions?At what temperature is this happening? What is the scale and how did you mount it on the tip?Thanks!

Hello matiak200,
The nanotube is about 4 to 5 micron in length and 25 nanometer in diameter. The video was taken at room temperature. One can mount the tube by passing a current from the wire across the nanotube to ground.
