What are they? What makes them awesome?

They are tiny magnetic unicorn horns.

Take a single layer of graphite and roll it into a tube. You now have one of the most promising new materials being studied. Superior strength per weight, flexible, expensive to make though.

pssh. show's what you know.


They're the constituent element in double rainbows.

They are looking at these for the construction of next gen photovoltaic cells or solar cells. I actually work at a company that makes Poly(3-Hexylthiophene) used in the making of these.

As I understand them, it's a unique way the carbon atoms bond under certain conditions. Very strong and lightweight. Will replace a lot of the Kevlar products when they're able to be grown commercially.

Again, as I understand it.

Also there is little to no resistance in them which makes them UNBELIEVABLE electric and heat conductors. Problem is size, assembly, and manufacturing. Figure out the junction problem and these badboys would rockout for heat dissipation and electrical current conductors.

Hey now, c'mon... don't you think that's... wait... you said "poop".

Carbon nanotubes were all the rage at my alma mater (Rice). I was just a dumb premed and didn't investigate as to what the fuck those things were...

im going to costa rica next month to have my skeleton replaced with a carbon nano-tube frame. no more broken bones.

If we can produce them cheaply ,they will be to the 21st century what Computers were to the 20th.

Interesting, how do they compare to high temperature super conductors? Is there any diamagnetic effect?

Single or multi-walled?
Link Posted: 9/14/2010 4:39:04 PM EDT
if the ends of the nanotube shown in fig 8-16 are uncapped, the result is a hollow tube of a very small dimension.
such nanotubes have been synthesized both with single and multiple walls (multiple layers built up on the outside of the innermost tube).

One of the most promising potential application of such structures is in the electronics industry.

TV science people claim, if/when they can ever be grown and manipulated industrially, nanotubes could be used to make super capacitors that would have capacities better than modern li-poly batteries, but be able take on a charge in an instant, and discharge as fast, or slow, as applications might require without the degrading like modern batteries.

That technology would take the electric car concept from zero to hero

Not sure. I would imagine since the equations that govern magnetics resemble those of heat transfer. Just learned about them as conductors in passing from a lecture last week. Just a guess on the magnetics thing since ANSYS uses the same solver for analyzing electric potential, magnetics, and energy flow.

Carbon mantubes. Superior strength AND flexible!
Link Posted: 9/14/2010 6:18:18 PM EDT
Even the much easier to fabricate via CVD multi-walled nanotubes still have incredibly high surface area, and can still maintain a good degree of substrate affinity (worked with them for biosensing applications), though the electronics applications really are all in the compact C60 based single wall nanotubes, and doping them to create circuits with novel properties.

Ftfy. And I'm amazed that we've only seen two or three mouthbreathers in this thread.

According to what little research I've done, these things could blow current bullet proof ratings out of the water. Imagine Level IV soft armor. Something that's never been done before. Possibly even higher than Level IV.
