    The Wonderful World of Nanotubes:
    Structure, Properties, and Applications
    by Roberto M. De Bari

    http://www.rci.rutgers.edu/~rdebari/nano.html

    is a very nifty nanotube website.

    Some tasty tidbits...

    Ever heard of Cerrolow-117?

    A material, marketed under the name Cerrolow-117, is
    an alloy composed of 44.7% bismuth, 22.6% lead, 8.3%
    tin, 5.3% cadmium, and 19.1% indium.

    Did you know nanotube structures can be molded?

    "Xu and colleagues made Y-shaped nanotubes by casting
    them. They used an electrochemical process to etch out
    Y-shaped moulds in a thin sheet of aluminium, and then
    they deposited carbon onto the mould walls to form the
    nanotubes. They then freed the tubes by dissolving the
    aluminium template."

    And check out the electron micrographs at the bottom
    of the same page.

    I thought the melting simulation at

    http://www.rci.rutgers.edu/~rdebari/structure.htm

    was interesting.

    Finally, when I got to the last page I noticed at the
    bottom that it says "Revised: April 24, 2000",
    suggesting to me that these ancient wonders--encoded
    in the now faded and ossified bytes from that distant
    era--have no doubt been surpassed by newer wonders,
    awaiting only to be googled from out the jittering
    tendrils of our primitive--but much
    loved--pre-singularity übermind.

    To sleep perchance to dream....

    Best, Jeff Davis
