- Nanotube, heal thyself
02-15-2007 · EurekAlert!
Pound for pound, carbon nanotubes are stronger and lighter than steel, but unlike other materials, the miniscule carbon cylinders remain remarkably robust even when chunks of their bodies are blasted away with heat or radiation. A Rice University study in the Feb. 16 issue of Physical Review Letters offers the first explanation: tiny blemishes crawl over the skin of the damaged nanotubes, sewing up larger holes as they go.

- Toward world's smallest radio: nano-sized detector turns radio waves into music
10-17-2007 · EurekAlert!
Researchers in California report development of the world's first working radio system that receives radio waves wirelessly and converts them to sound signals through a nano-sized detector made of carbon nanotubes. The 'carbon nanotube radio' device is thousands of times smaller than the diameter of a human hair. The development marks an important step in the evolution of nano-electronics and could lead to the production of the world's smallest radio, the scientists say.

- The sensitive side of carbon nanotubes: Creating powerful pressure sensors
10-23-2007 · EurekAlert!
Blocks of carbon nanotubes can be used to create effective and powerful pressure sensors, according to a new study by researchers at Rensselaer Polytechnic Institute. Taking advantage of the material's unique electrical and mechanical properties, researchers repeatedly squeezed a 3-millimeter nanotube block and discovered it was highly suitable for potential applications as a pressure sensor. No matter how many times or how hard they squeezed the block, it exhibited a constant, linear relationship between how much force was applied and electrical resistance.
