Brownian motion melts a quasicrystal of tiny Penrose tiles

A quasicrystal made from tiny Penrose tiles that undergo Brownian motion has been created by Po-Yuan Wang and Thomas Mason at the University of California-Los Angeles. The duo was able to track changes in the 2D structure as tiles moved around, observing a range of effects including melting. As well as shedding further light on the properties of quasicrystals, the new lithographic fabrication technique could be used to study a wide range of colloidal systems.
