Nanoseries 3/5 : How can we see carbon nanotubes?

Third video of the nanoserie sponsored by WomenInNano, nano2hybrids and Vega Science Trust.

Let's see how different two carbon nanotube sample are!

Hello all,  Well then the conclusion of the video is that the arc discharge one gives us the kind structure we want while the CVD comes in its own bizarre way

[nano2hybrids]

Arc-discharge gives straighter tubes but does not mean that is what we want necessary. For some applications we may want defected tubes (for example if you want attached other molecules to the tube).

But most importantly, by arc-discharge a lot of byproducts are produced and it is difficult to produce large quantities of tubes.

CVD produces "wavier" tubes but in higher quantities and like "growing" from a carpet which is more useful for some applications. CVD is easier for mass production.

Where are the rest of the series?

[nano2hybrids]

Hi Allgoo19,

I have been very busy this last month, so I haven't got time to finish the last two videos.

But keep tuned! I will upload them in January -consider them your late Xmas present ;)

Thank you for this series! its was very informative, and i watched them all.

I love the way they place the spaghetti in the same position as the nanotubes

[TheSpanishkoala]

The spaguetti/nanotube analogy refers only to the appearance but not the properties!

@JesterFarce Sorry your comment was deleted for some unknown reason.

"You used spaghetti as an example to explain the different properties of the two carbon nanotube variants - would it be correct in saying that the Arc-discharge method produces more brittle nanotubes, while CVD produces more flexibility in their composition? So wouldn't CVD actually be more useful in eventually constructing useful applications in this technology?..."

Thumbs up if you think nicole should of been naked.

For science.

[mcRioRemedy]

that SEM is one piece of AMAZING machinery.

humans are so clever its unreal (well some of us)

[abobjenkins]

Since the atoms could not be seen, how do they know the atomic structure?

[DrSAM69]

Ok yeah nanotubes great but....hm.did u fuck nicole?

[pufixas]

I WANT THAT TELESCOPE!!!

OMG... its AWESOME!
