Atoms in buckyball cages. (creating metallofullerenes by trapping lanthanum atoms inside buckyballs) (Brief Article)

From: Science News | Date: February 27, 1993| Author: Peterson, Ivars | Copyright information

It doesn't take much to trap a lanthanum atom inside a buckyball. Robert D. Johnson and his colleagues at the IBM Almaden Research Center in San Jose, Calif., create such metallofullerenes by drilling a hole in a graphite rod, stuffing the hole with a mixture of graphite and metal powders, then vaporizing the rod with an electric arc. Of the fullerenes found in the resulting soot, about 1 percent contain metal ato...

'Buckyball' II: the game continues. (newly discovered C60 molecule, buckminsterfullerene)
Science News ; In just a few months, the newly discovered moecule C.sub.60 -- buckminsterfullerene, or buckyball for short -- has become the center of a wide range of theoretical and laboratory investigations (SN: 11/23/85, p. 325). This molecular appears to have a geometric structure like the pattern on a soccer
