A quasiperiodic crystal, or quasicrystal, is a structure that is ordered but not periodic. A quasicrystalline pattern can continuously fill all available space, but it lacks translational symmetry. [2] .

Quasicrystal, matter formed atomically in a manner somewhere between the amorphous solids of glasses (special forms of metals and other minerals, as well as common glass) and the precise pattern of crystals. Like crystals, quasicrystals contain an …

More than 35 years and 11 000 publications after the discovery of quasicrystals by Dan Shechtman, quite a bit is known about their occurrence, formation, stability, structures and physical properties.

2019年1月8日 · In Russia’s far east, a motley crew of conspirators races against time to solve a mystery hidden for billions of years. The enigma could link a speck of rock found in the dusty basement of an...

2020年4月21日 · Unlike the soft crystalline metals, quasicrystal alloys are exceedingly hard and have a high degree of surface slipperiness, motivating the first commercial application of quasicrystals as a cookware coating alternative to Teflon (Gibbons and Kelton 1998).

2020年12月17日 · This book provides an interdisciplinary guide to quasicrystals, the 2011 Nobel Prize in Chemistry winning topic, by presenting an up-to-date and detailed introduction to the many fundamental ...

Quasicrystals are novel phases of matter with long-range order exhibiting the symmetry elements forbidden to periodic crystals (Bindi et al., 2015). The first and, until now, the only known natural quasicrystal, Al 63 Cu 24 Fe 13 with icosahedral symmetry was reported in 2009.

2023年10月19日 · In Quasicrystalline materials, the arrangement of atoms or molecules is ordered and aperiodic. The atomic structures are arranged in a pattern such that there are no gaps between the structures, but no pattern ever repeats itself. The structures repeat themselves throughout the pattern, but in completely different orientations every time.

2025年3月12日 · Quasicrystals have structural properties intermediate between crystalline and amorphous materials. They can be synthesized in the lab but, as Luca Bindi explains, they may also be present in...

2023年10月24日 · Quasicrystals were once thought to be impossible, as crystals were the only stable form of matter. Crystals allow for periodic patterns of atoms while quasicrystals allow for an ordered, yet non-periodic pattern that results in rotational symmetry.
