Method Could Help Carbon Nanotubes Become Commercially Viable

10-06-2006 · ScienceDaily

Carbon nanotubes are intriguing new materials, but a fundamental problem relating to their synthesis has limited their widespread commercial use. Current methods for synthesizing the materials produce mixtures of tubes that differ in their diameter and twist. Now Northwestern University researchers have developed a new method for sorting single-walled carbon nanotubes. The method works by exploiting subtle differences in the buoyant densities of carbon nanotubes as a function of their size and electronic behavior.

NRL scientists produce carbon nanotubes using commercially available polymeric resins
02-07-2008 · EurekAlert!
Scientists at the Naval Research Laboratory have successfully produced carbon nanotubes in high yields in bulk solid compositions using commercially available aromatic containing resins. The concentration of multi-walled carbon nanotubes and metal nanoparticles can be easily varied within the shaped carbonaceous solid. Carbon nanotube containing fibers and films have also been formulated from the precursor compositions. The potential range of applications is huge, including structure, energy, sensors, separation/filtration, battery, electronic displays and nanoelectronic devices.

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.
