Defects in Static Elasticity of Quasicrystals
Crystals, 2017 A review on mathematical elasticity of quasicrystals is given. In this review, the focus is on various defects of quasicrystals. Dislocation and crack are two classes of typical topological defects, while their existence has great influence on the ...

2D honeycomb transformation into dodecagonal quasicrystals driven by electrostatic forces
Nature Communications, 2022 Quasicrystals are perfectly ordered crystals lacking translational symmetry. Here the authors unravel the formation mechanism of two-dimensional dodecagonal quasicrystals that arise from systematic modifications of a hexagonal honeycomb structure.

Formation of a single quasicrystal upon collision of multiple grains
Nature Communications, 2021 Quasicrystals exhibit long-range order without periodicity. The authors report an approach for quasicrystal fabrication and show through in situ imaging and corresponding simulations the formation of a single decagonal quasicrystal arising from ...

Journal of Research of the National Institute of Standards and Technology, 2001 The discretely diffracting aperiodic crystals termed quasicrystals, discovered at NBS in the early 1980s, have led to much interdisciplinary activity involving mainly materials science, physics, mathematics, and crystallography. It led to a new understanding of how atoms can arrange themselves, the role of periodicity in nature, and has created a new ...

Structural Disorder in Quasicrystals [PDF]
Archives of Metallurgy and Materials, 2020 One of the challenges of modern crystallography of complex systems (complex metallic alloys, proteins, aperiodic crystals and quasicrystals) is to properly describe the disorder in these systems and discuss correctly the refinement results in terms of ...

Interface crack between dissimilar one-dimensional hexagonal quasicrystals with piezoelectric effect [PDF]
, 2019 In this paper, an interface crack between dissimilar one-dimensional (1D) hexagonal quasicrystals with piezoelectric effect under anti-plane shear and in-plane electric loadings is studied. By using integral transform techniques, the mixed boundary value
