Experts say the new
fullerene, described in tomorrow's issue of Nature, may be easier to fashion into everything
from high - temperature superconductors to high - strength materials.
Single - wall
fullerene nanotubes were converted
from nearly endless, highly tangled ropes into short, open - ended pipes that behave as individual macromolecules.
The
fullerene cages prevent water molecules
from freezing, meaning that the hydrogen atoms continue to spin and conversion is still able to occur.
Today,
fullerenes — which are popularly known as buckyballs — are being investigated for everything
from new superconductors and three - dimensional polymers, to catalysts and optical materials, although they have yet to spawn any commercial applications.
Even the
fullerene tracers that were once warmly received have come under attack, because geochemist Ken Farley of Caltech in Pasadena found no helium in P - T rocks
from Meishan when he tried to replicate Becker's work.
Becker next succeeded in isolating
fullerene molecules directly
from meteorites.
I've been experimenting with T10 dextran coated iron oxide nanoparticles, obviously not the same as
fullerenes, but still a very interesting tool, I've been testing if the coating is giving the particle antioxidant abilities because of it's the (basically) indigestable sugar chains (glucose) creating a high surface area which are largely made
from hydroxyl groups, I hypothesised this act's as a «sink» for reactive oxygen species converting them to water.
The telltale
fullerenes containing helium and argon were extracted
from sites where the Permian - Triassic boundary layer had been exposed in Japan, China and Hungary.
Becker, L., R.J. Poreda, A.G. Hunt, T.E. Bunch, and M. Rampino, 2001: Impact event at the Permian - Triassic boundary: Evidence
from extraterrestrial noble gases in
fullerenes.
Although so - called nanomaterials have yet to cause any illnesses or problems in humans, a number of studies have shown that they can be harmful to animals;
fullerenes, for example, were found to cause oxidative stress in the brains of largemouth bass in a recent study done by researchers
from three different institutions.
