MOLECULAR STRUCTURE: Physicists Glimpse How Quasicrystals Boogie.
A new series of rapid-fire photographs has finally captured the expected dance of atoms in the changing latticework of a quasicrystal, the slightly unpredictable cousin of crystals. Although scientists had observed defects in quasicrystalline structures left behind by the flip-flops, called phasons, this is the first time anyone has spotted a real phason in action.
