Slashdot linked up this tech journal article detailing recently patented processes for building 3-D "nanostructures". By using innovative laser techniques, scientists are able get these materials to self-assemble atom by atom. By removing both impurities and imperfections, the results are far superior to anything that could be created with conventional processes. The article specifically mentions copper that's as strong as steel, as well as new kinds of computer circuits that could allow the construction of a 10 terabit memory chips.

Because these processes are highly automated and involve fewer steps than previous techniques, the materials they produce are much cheaper. Cheap enough, in fact, that some companies appear to already be using them, and products incorporating the materials are expected to be commercially available in as little as 5 years.
