The Ammann–Kramer–Neri tiling model of a P‐ZnMgEr Bergman‐type quasicrystal based on in‐house X‐ray diffraction

Acta Crystallographica Section B, EarlyView.
A structural solution is presented of a primitive icosahedral ZnMgEr quasicrystal representing the Bergman‐type family. The structure model is based on atomic decoration of the Ammann–Kramer–Neri tiling.This study presents the atomic structure solution of a primitive icosahedral Zn70.83Mg20.31Er8.86 quasicrystal using in‐house X‐ray diffraction and the

Dynamics of particle flips in two-dimensional quasicrystals

, 2010
The dynamics of quasicrystals is more complicated than the dynamics of periodic solids and difficult to study in experiments. Here, we investigate a decagonal and a dodecagonal quasicrystal using molecular dynamics simulations of the Lennard-Jones-Gauss ...

Quantitative analysis of facet growth during directional solidification of salol

Acta Crystallographica Section B, EarlyView.
This study offers a comprehensive analysis of facet growth during directional solidification of salol, focusing on the dynamic evolution of the solid–liquid interface. A novel strategy was developed to identify the crystallographic nature of the observed facets, whose growth is mainly governed by two‐dimensional nucleation, with deviations attributed ...

From the Fibonacci Icosagrid to E₈ (Part I): The Fibonacci Icosagrid, an H₃ Quasicrystal

Crystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

Interaction between a Screw Dislocation and Two Unequal Interface Cracks Emanating from an Elliptical Hole in One Dimensional Hexagonal Piezoelectric Quasicrystal Bi-Material

Crystals, 2022
Utilizing conformal transformation, a screw dislocation interacting with two unequal interface cracks emanating from an elliptical hole in a one-dimensional hexagonal piezoelectric quasicrystal bi-material was studied.

Formation of a stable deacagonal quasicrystalline Al-Pd-Mn surface layer [PDF]

, 2001
We report the in situ formation of an ordered equilibrium decagonal Al-Pd-Mn quasicrystal overlayer on the 5-fold symmetric surface of an icosahedral Al-Pd-Mn monograin.

Analytical Solution for a 1D Hexagonal Quasicrystal Strip with Two Collinear Mode-III Cracks Perpendicular to the Strip Boundaries

Crystals, 2023
We considered the problem of determining the singular elastic fields in a one-dimensional (1D) hexagonal quasicrystal strip containing two collinear cracks perpendicular to the strip boundaries under antiplane shear loading. The Fourier series method was

Emergent Quasicrystalline Symmetry in Light-Induced Quantum Phase Transitions

, 2019
The discovery of quasicrystals with crystallographically forbidden rotational symmetries has changed the notion of the ordering in materials, yet little is known about the dynamical emergence of such exotic forms of order.
