The stability of the predicted boron cage stems from its unique structural geometry
Since C60 fullerene’s discovery in 1985 and the subsequent Nobel prize awarded to Robert Curl, Harry Kroto and Richard Smalley in 1996, researchers have been challenging themselves to make similar structures with other elements in the hope of finding exciting alternative nano building blocks.
