Rice University Researchers Make Breakthrough in Carbon Nanotube Processing

Breakthrough builds on process used in plastic industry for years

One of the most highly researched fields today is the production of carbon nanotubes. Carbon nanotubes hold high promise for many uses from a new generation of cancer treatment down to better electronic devices. The trick for researchers is to find a method of creating the nanotubes in bulk.

Researchers at Rice University have discovered a method of industrial-scale processing of pure carbon nanotube fibers. The breakthrough is the result of a nine-year program and the method builds on the processes that have been used by chemical firms for decades to produce plastics.

According to the researchers, one major discovery remains before high-quality carbon nanotubes can be created and utilized. Current methods produce a myriad of different carbon nanotubes with different properties, lengths, and diameters. Researchers are working to find a method of crating only one type of carbon nanotubes. When batches of metallic conductive nanotubes can be created the use of nanotubes will boom.

But, you can't have a mass amount of nano technoligy because carbon nanotubes have only have had been made at extermly small levels.

One day they will be able to grow themselves like living cells do when they divide.

I'm reallly interested in this. What do you think are some good areas of investment for nanotechnology and when do you thing it might start paying off? Seems like they are on the brink.

What do they mean 'metallic' nanotubes? I thought they all had to be carbon.

Is it possible to put a gold atom in a carbon fullerine ball? And is it then possible to make
a chain, or bead string out of these gold-laced fullerenes? Could the beaded string then be placed inside
an insulating carbon nanotube and have the whole assempbly used as an insulated, conductive nano-wire ?

The main question, I guess, is whether or not the 'caged' gold atoms would even conduct in the first place,
being that they're inside of a very strict ball.

And yes, atoms and molecules can be contained in a buckyball.

A few years ago researchers made a buckyball out of DNA, and it self-assembled.

I see, so the carbon nanotubes can therefore be conductors or semi-conductors, depending
on how the lattice is rolled.




I wonder...
Would a carbon fullerine-ball be able to contain a radioactive atom?
Uranium, for example?
Or would it destroy the shell?


What about ions?
Can an ion be contained in a carbon ball?
Would its electrical charge affect ions outside of the ball?
