First Experimental Evidence of Boron “Buckyball”

July 14, 2014

0 Comments

An international team of researchers has shown that boron, carbon’s neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Providence, Rhode Island (Brown University) — The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a […]
