460.~ Producing fullerene (i.e., C60) type superconductor or analog thereof

DEFINITION

Classification: 505/460

Producing fullerene (i.e., C60) type superconductor or analog thereof:

(under subclass 300) Process wherein the superconducting material is a doped or nondoped 60 carbon hollow, closed-caged molecule resembling a Buckminster Fuller geodesic dome or a homologous series of hollow, closed-caged molecules usually having 60 or more carbon atoms, referred to as fullerenes.

(1) Note. While, at this time, several fullerenes fail to meet the Class 505 requirement of Tc 30 K, Ebbsen, et al., Nature, 1991, 352 222, have disclosed fullerenes doped with cesium (Cs) or rubidium (Rb) having Tc 30 K as required by the class definition.
