Movie 2 : Carbon nanotubes as you have never "seen" them

[ricktbdgc]

I swear that looks like a nano penis

I saw a video, I think it was Ira Flatow doing the interview. He was interviewing a guy at MIT. He answered "it's classified" to a lot as he was working on millitary stuff. They grew a carbon nanotube forest and it had video that showed single carbon atoms as they where multiplying. When it was done it said MIT imprinted in the "forest" and the professor jokingly blamed his students. This video seem imposible to find now and I wonder how the video was made? Can Sarfus see single carbon atoms?

@tripmix2 Hi, not sure what Sarfus is? Haven't seen MIT video but have seen video growing nanotubes in a tube furnace with transparent walls, so you can film it from the side with a camera (the gas goes through the tube from left to right). See youtube video XetX-OsZj54 - also you can grow in the microscope, see TaNCWcumeyg

Thanks for posting. How many times was your sample magnified?

[nano2hybrids]

I don't remember exactly but it is something between 500 000 to 1 000 000 times.

Okay, thanks!

Isn't it hard to make those tiny little metal particles stick to tiny little nanotubes? Do you just put the nanotubes in some metal, and hope some of it sticks?

[quixotic86]

there are multiple ways of attaching nanoparticles to carbon nanotubes which include using positively charged gold nanoparticles which will be attracted to specific types of CNTs. Also you could use a reduction method in which you use a gold salt such that the result is actual covalent attachment of nanoparticles on the nanotubes (chemisorption).

[nano2hybrids]

We've got different ways of doing it - in general we heat metal in a vacuum chamber so individual metal atoms pass through the chamber and land on the nanotube surfaces. We first treat the nanotube surfaces though with a plasma to 'roughen them up' so the metal sticks better - more details on our website about this...

pinat is the one who invented that

[legomasterchief]

Science is fun! :D

[pitviper12345]

cool! those dots are molecules right? amazing!

[nano2hybrids]

Kind of - they're ultra-small clusters of metal atoms, so the size of large molecules...

[supertarget76]

I'm worried about the effects carbon-nanotubes will have on our health. Will carbon-nanotubes be the asbestos of the future?

[nano2hybrids]

Hi there - we'll hopefully do a video about this soon.. Meanwhile if you check our main site, nano2hybrids net, we've posted quite a few blogs items about this.

[nanotechworld]

wow incredible resolution first I thought it might have been a buckyball

[lightwinged]

aa! this is a multi-walled tube with buckyballs, rigt?

[nano2hybrids]

No there are no buckyballs in this sample - the black dots you can see are nanoscale metal particles which were added to make an ultra-efficient gas sensor. There's more details, explanation, etc on our website, feel free to add comments and questions there! It's up and running now.

[tehsma]

awesome!

[nano2hybrids]

Hi there will be much more about nanotubes and their function on our website, nano2hybrids net - new version of the site to appear in May or June hopefully...

[SUPERBURRITO]

Explain Nanotubes and theire function. Thanks. Nice video.

i can tell you that nasa is trying to industrialise the creation of carbon nano tubbes to set up a space elevater cool idea but its a god 50 years off from what i have seen
