3. 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.

6. New techniques pave way for carbon nanotubes in electronic devices
   11-06-2006 · EurekAlert!
   Many of the vaunted applications of carbon nanotubes require the ability to attach these super-tiny cylinders to electrically conductive surfaces, but to date researchers have only been successful in creating high-resistance interfaces between nanotubes and substrates. Now a team from Rensselaer Polytechnic Institute reports two new techniques for placing carbon nanotube patterns on metal surfaces of just about any shape and size.

8. Volcanoes and nanotechnology
   02-06-2007 · EurekAlert!
   Since their discovery, carbon nanotubes and carbon nanofibers have been used in a wide variety of applications. However, because their production on an industrial scale remains expensive, their commercial use in such areas as catalysis has remained unthinkable. This could now be changing: Dang Sheng Su and his co-workers have used igneous rock from Mount Etna to produce carbon nanotubes and fibers.

9. New nanotube findings by Stanford researchers give boost to potential biomedical applications
   01-28-2008 · EurekAlert!
   Now it can be said with certainty: what goes in, does come out, at least with regard to carbon nanotubes and mice. But, the ramifications fall more in the realm of biomedicine than Newtonian physics. The newfound knowledge alleviates concerns that nanotubes used to deliver medicine might linger in the organs after their job was done and eventually prove toxic. The findings pave the way for further research into biomedical applications of carbon nanotubes.
