The article in the Institute of Physics' (IOP) Nanotechnolgy entitled "Molecular dynamics simulations of carbon nanotube-based gears" offers a glimpse into the future of what scholarly publishing could be. Concepts "come alive" in the multimedia appendices. The eight page article (available in Adobe Acrobat [.pdf] and postscript format) is tailored for specialists and includes some photos, but all scholars can appreciate the eight mpeg movies (ranging from 375 KB to 2.25 MB) that show these tiny gears in action. Note that this article is one of a rotating set of free Nanotechnology articles, and may be removed in the future.
