Nanotube devices closer to market

Filed under: Business, Technology — Tags: , , , — David Kirkpatrick @ 11:50 am

I can blog all day about nanotechnology breakthroughs and we can get excited about the theoretical improvements nanotech promises, but the proof in the pudding is getting nanotech to the market. Particularly some of the more dramatic applications. Improving existing items through nanotech is great, but I want the game-changers to get out there in the real world.

It look like electronic application for nanotube devices are getting close to that point. Couldn’t happen too fast for me.

From the link:

Circuits made from carbon nanotubes are intrinsically faster than those made from silicon. But while products from tennis rackets to bike frames take advantage of nanotubes’ light weight and strength, no commercial devices have yet exploited their remarkable electrical properties.

That’s partly because researchers have had difficulty creating films or other assemblies of nanotubes that preserve those properties: nanotube arrays, for example, proved nowhere near as electrically conductive as tubes taken singly. But a number of groups have found ways around that ­obstacle, and the result has been a flurry of prototype electronic devices that use nanotubes. Here is a sampling.
