Structure models of quasicrystal approximants deduced from the strong reflections approach in quasicrystals: types, systems and techniques

, 2010
Quasicrystals are metallic alloys that exhibit atomic scale order, but not periodic order. Atomic scale properties of these materials are different from single crystalline material, for example, extraordinary mechanical properties, electrical and thermal

Topological Polar Textures in van der Waals Moiré Superlattices

Small Structures, Volume 7, Issue 2, February 2026.
Moiré superlattices allow the realization of several novel properties, including the formation of complex topological polarization textures in ultrathin samples consisting of layered 2D materials. This review highlights the rapid progress in this emerging field, both through theory and experiment, discusses the field's potential implications, and draws

On Elastic Stability and Positive Definiteness for One-Dimensional Quasicrystals

Crystals
In this work, a proper formulation of the elastic stability and positive definiteness of the elastic energy density of one-dimensional quasicrystals is provided. Based on an appropriate Voigt notation, the Sylvester criterion is applied and the necessary

Bridging the local configurations and crystalline counterparts of bulk metallic glass by nanocalorimetry

Journal of Materials Research and Technology, 2019
The structural understanding of crystallization in bulk metallic glasses (BMGs) has attracted much attention while rapid crystallization occurring under controllable conditions is less involved.

Shapes of quasicrystals

, 1997
In the present article, we review the present status of our understanding of the shapes of quasicrystals. Although theoretical efforts exist to determine the equilibrium shape of quasicrystals, very little experimental information exists.

Shock Synthesis of Five-component Icosahedral Quasicrystals [PDF]

, 2017
Five-component icosahedral quasicrystals with compositions in the range Al_(68–73)Fe_(11–16)Cu_(10–12)Cr_(1–4)Ni_(1–2) were recently recovered after shocking metallic CuAl_5 and (Mg_(0.75)Fe_(0.25))_2SiO_4 olivine in a stainless steel 304 chamber ...

Laser induced desorption and ablation: mechanism of metal removal from an Al-Cu-Fe alloy and a quasicrystal of the same composition

International Journal of Photoenergy, 2001
Quasicrystals are a special class of metallic alloys that share some of the properties of crystals. Their structures reduce to a single repeating unit like that of the unit cell of a crystal.
