Thanks to the rising trend toward miniaturization, carbon nanotubes – which are about 100,000 times thinner than a human hair and possess several unique and very useful properties – have become the choice candidates for use as building blocks in nanosized electronic and mechanical devices. But it is precisely their infinitesimal dimensions, as well as their tendency to clump together, that make it difficult for scientists to manipulate nanotubes.

Sticky nanotubes hold key to future technologies

After powering the micro-electronics revolution, silicon could carve out an important new role in speeding the debut of ultra-clean fuel cell vehicles powered by hydrogen, researchers in China suggest. Their calculations show for the first time that silicon nanotubes can store hydrogen more efficiently than their carbon nanotube counterparts.

New nanotube sensor can continuously monitor minute amounts of insulin

When it comes to scientific breakthroughs, we usually leave the coverage to our science writers, because they have a fighting chance of understanding them.

Nanochannels impose order by capillary action

harminka — Thu, 24 Jan 2008 12:09:58 -0600

Carbon nanotubes are attractive candidates for use as the active elements in the next generation of electronic devices. However, it has proven incredibly difficult to align nanotubes within device architectures.

Chemical vapor deposition grown carbon nanotubes for interconnect technology

Computers and electronic devices of the future will utilise technologies not currently available. An example of such a technology is the use of carbon nanotubes as interconnects for computer chips. This is now a step closer to reality with some new work from nanotechnology researchers within the Materials Ireland Polymer Research Centre at Trinity College Dublin.

Flexible electronics and surfboards made from same new material!

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and medical applications. The methods and new titanium oxide materials may lead to improved catalysts for hydrogen production, more efficient solar cells, and more protective sunscreens.
