Quasicrystalleilla
Quasicrystals are a class of atomic structures that possess long-range order but lack translational periodicity. Unlike traditional crystals, which exhibit repeating patterns of atoms that can be described by a translation vector, quasicrystals have symmetries that are forbidden in conventional crystallography, such as five-fold rotational symmetry. This seemingly paradoxical nature arises from their unique atomic arrangements, which can be thought of as projections of higher-dimensional periodic structures.
The discovery of quasicrystals in 1982 by Dan Shechtman revolutionized the field of materials science. Prior
Quasicrystals exhibit a range of interesting properties. They are often hard, brittle, and possess low coefficients
