78) In December, Rolling Stone named Buckyballs
"Toy of the Year" in its annual gift guide.
would make excellent drug delivery devices.
Carbon nanotubes are one of the more technologically promising nanostructures, although soccer ball-shaped buckyballs
-- the first nanostructures to be discovered -- also have their place (see story opposite).
What do buckyballs
and trapped gas have to do with asteroids and mass extinction?
They produced a brown, spongy material in which hydrophobic (water-avoiding) buckyballs
forced the hydrophilic (waterseeking) amines to the outside, where passing carbon dioxide could bind to the exposed nitrogen.
gave rise to some extremely unusual electrical behavior.
So, the search turned to finding a way to "build" a buckyball
to the rescue: The molecule that won its discoverers this year's Nobel Prize in chemistry may also someday win a bodily battle against bacteria.
These molecules, part of a class called fullerenes, were touted as the next big thing in electronics; yet after a quarter century, nobody has a buckyball
running an iPhone.
Since then, chemists have synthesized some 5,000 variants of the buckyball
, including elongated spheroids, sheets of carbon and microscopic tubes.
238) describes placing a beryllium-7 into a 60-carbon molecule known as a buckyball
He and his colleagues report in the April 18 Science that a buckyball
pair with added electrons might even form molecular bonds, similar to those in hydrogen molecules.
