Nature Chemistry | The Sceptical Chymist

A nanotube fix

Being an associate editor of Nature Nanotechnology, I now know a lot more about carbon nanotubes that I ever thought I would. There’s a lot I don’t know, however, and I was surprised by what I learned today…

Every now and then I need to look up some interesting (or otherwise) little fact about nanotubes and just get an idea of what the popular terminology is, i.e., is it a ‘chirality vector’ or a ‘chiral vector’? I won’t spoil that one for you. Anyway, first port of call, as with a lot of people, is the web, and, in particular, Wikipedia. Now, I know that any information garnered from Wikipedia might not necessarily be 100% accurate, but it’s a good place to start for casual references.

So, as I was scanning through the entry on carbon nanotubes, I was interested to see how their cost is normalized to the price of a more widely known chemical product in society:

Single-walled nanotubes are still very expensive to produce, around $1500 per gram as of 2000 (compared to marijuana, which generally costs between $10 and $30 per gram, depending on who you know and how sweet the nug is), and the development of more affordable synthesis techniques is vital to the future of carbon nanotechnology.

I don’t know if this is Wkipedia vandalism or not… anyway, maybe this new standard will give the Big Mac index a run for its money…

    Wow, that was quick – vandalism fixed… you can obviously check out the page history of course…

    Very interesting!

    Your post motivated me to dig deeper into the sources and prices of single-wall and multi-wall nanotubes. I have posted a review on my blog:

    Single-wall nanotubes are still quite expensive. Unless a breakthrough application is found, I seriously doubt if these can be a commercial success. Multi-wall nanotubes, on the other hand, seem to be gaining momentum – production capacity going up and prices coming down.
