| The arrangement of atoms in a quasicrystal displays a property called long-range order, which is lacking in amorphous metals. |
| At low temperatures motion of atoms within the solid is difficult, and phason strain may be easily frozen into the quasicrystal, limiting its perfection. |
| Analysis of an endlessly single-mode penrose-tiling photonic quasicrystal fiber. |
| Since a high-resolution electron microscope image of aluminum-manganese-silicon quasicrystal clearly reveals an axis of fivefold symmetry, it may be concluded that the arrangement of atoms lacks translational periodicity. |
| Indeed, it appears that aluminum is unusually prone to quasicrystal formation, but there do exist icosahedral quasicrystals without it. |
| What Dr Shechtman had discovered, he realised, was a new sort of material called a quasicrystal. |
