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
