Last year, Professor Andrew Barron, Ser Cymru chair in engineering at Swansea University, also a chair at Rice University in Texas, found buckyballs
gain the ability to capture carbon dioxide when combined with the chemical polyethyleneimine (PEI).
(84) At the time that Maxfield & Oberton began selling Buckyballs
, what constituted a "children's product" was defined by statute as "a consumer product designed or intended primarily for children 12 years of age or younger." (85) According to Zucker, Buckyballs
"were never intended, designed or marketed for children; so we labeled them for ages 13+ to make that clear." (86) In August, however, a new, mandatory toy safety standard from the CPSC came into effect, redefining a child as someone "under 14 years of age," making Buckyballs
's "13+" label noncompliant.
Spherical fullerenes, well known as "buckyballs
" ([C.sub.60]), were prepared in 1985 by Kroto et al.
," which are cage-like nanostructures made of
Reaction (1) produced a new buckyball
[C.sub.84][H.sub.2] (I) by forming seven butagons, five pentagons, five hexagons, and two decagon cycles from three circulene molecules.

Under certain conditions such as exposure to light, buckyballs
can generate highly reactive "singlet oxygen," which can be damaging to tissues.
A third form of carbon-the others are diamond and graphite-the buckyball
(C60) is a highly stable molecule consisting of 60 carbon atoms in an arrangement of 12 pentagonal and 20 hexagonal faces.
Research by academics at Swansea University and Rice University, in Texas, proved that aminerich compounds are highly effective at targeting and capturing greenhouse gas, when they are combined with football-shaped carbon-60 molecules, also known as "Buckyballs
Hutchison will get the buckyball
rolling at 7 p.m., but people can come early.
Words like buckyball
' and `nanotube' sound as if they have been lifted from the pages of science fiction.
