Recently Yadong Yin and his colleagues in Paul Alivisatos's laboratory were
experimenting with ways to modify the surfaces of nanocrystals — particles only
a few billionths of a meter in size, comprised of only a few thousand atoms.
After exposing cobalt nanocrystals to sulfur, they examined the results under a
transmission electron microscope. (Berkeley Lab Science Beat 5/04)<BR><A

so far as to alienate a lot of its natural supporters, as it tried to argue that
the kinds of advanced nanotechnology that might spur popular fears were
impossible, and that those who felt otherwise were (despite being pioneers in
