Quasicrystals - Discovery, Structure and Properties [PDF]
Kemija u Industriji, 2012 Quasicrystals are solid materials the structures of which can have crystallographically forbidden symmetries, e.g. of the fifth order, and do not have the translational invariance charactistic for classical crystals.

Communications Physics, 2023 Aperiodicity and un-conventional rotational symmetries allow quasicrystalline structures to exhibit unusual physical and functional properties. In magnetism, artificial ferromagnetic quasicrystals exhibited knee anomalies suggesting reprogrammable ...

2D and 3D Nets by Self‐Assembly of Carbosilane Functionalized Polyphilic Liquid Crystals
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.In the shown compounds, the growing volume of the carbosilane side‐groups modifies the self‐assembly in liquid crystalline phases ranging from a square via a pentagonal to a hexagonal honeycomb and finally to a 3D (10,3)‐a double net. The structures are discussed in relation to inorganic solid‐state materials and the concept of “mesoatoms”.

Journal of Non-Crystalline Solids, 1985 We introduce the concept of quasicrystals and discuss their diffraction patterns. The idea of local isomorphism is argued to be a physically meaningful one.

Physical Review Research, 2021 Quasicrystals lack translational symmetry, but can still exhibit long-range order, promoting them to candidates for unconventional physics beyond the paradigm of crystals.

Results in Physics, 2023 We have investigated the linear propagation of light wave in three-dimensional photonic quasicrystal lattices by numerical simulation. The diffraction characteristics of the light waves in the longitudinal non-modulated, in-phase modulated and out-of ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Heterogeneous structures have demonstrated great potential for overcoming the long‐standing strength–ductility trade‐off in metallic materials. In this study, a novel dual‐gradient structure, characterized by gradients in both grain size and precipitate distribution, was successfully constructed in an Mg–2Zn–0.8Gd (wt%) alloy sheet via sliding

Line Defects in One-Dimensional Hexagonal Quasicrystals
MathematicsUsing the eight-dimensional framework of the integral formalism of one-dimensional quasicrystals, the analytical expressions for the displacement fields and stress functions of line defects, which are dislocations and line forces, in one-dimensional ...

Elastic Properties and Thermal Expansion Behavior of a Polycrystalline VMnFeCoNi High‐Entropy Alloy
Advanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.The high‐entropy alloy (HEA) V20Mn20Fe20Co20Ni20 (composition in at.%) can be made single‐phase face‐centered cubic (FCC) when annealed above 1338 K followed by water quenching. In this state, the alloy exhibits the greatest strength‐ductility combination of any quinary single‐phase FCC HEA.

Three-Dimensional Generalized Dynamics of Soft-Matter Quasicrystals
Advances in Materials Science and Engineering, 2020 The three-dimensional generalized dynamics of soft-matter quasicrystals was investigated, in which the governing equations of the dynamics are derived for observed 12-fold symmetry quasicrystals and possibly observed 8- and 10-fold symmetry ones in soft ...
