Diamond Nanotubes Created
raxxy writes to tell us that researchers at the U.S. Department of Energy's Argonne Nation Laboratory have taken the next step in nano development. Combining the process for 'growing' diamonds and the latest in carbon nanotubes has given birth to a diamond-nanotube composite. From the article: "Diamond has its drawbacks, however. Diamond is a brittle material and is normally not electrically conducting. Nanotubes, on the other hand, are incredibly strong and are also great electrical conductors, but harnessing these attributes into real materials has proved elusive. By integrating these two novel forms of carbon together at the nanoscale a new material is produced that combines the material properties of both diamond and nanotubes."
Congratulations. You can do vapor deposition of diamonds, and you can do vapor deposition of carbon nanotubes. So can everyone else. You can do them both at the same time? Interesting. Too bad you can't control the process beyond the ratio of nanotube to diamond.
What about average tube length? Alignment? Bonding with the diamond? Anything beyond what you'd get if you mixed extremely fine diamond powder and nanotube powder, mixed and compressed? Guess not.
However "Ultrananocrystalline(tm)" sure sounds cool. Maybe the innovation is in the buzzword.
