, 1989 There are several incentives to identify the analogues of dislocations and disclinations in quasicrystals. Penrose patterns are two-dimensional systems, and according to phase space counting fluctuations of the atomic displacements are so strong that exact long-range order is reduced to quasi-longrange order just as in periodic crystals.

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning
Advanced Intelligent Discovery, EarlyView.This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Mechanics of Interfacial Cracks between dissimilar Quasicrystals [PDF]
, 2010 We analize the steady propagation of a straight interfacial crack between two dissimilar planar quasicrystals in pure elastic setting and infinitesimal deformation regime. A closed form solution to the balance equations is furnished. Inertia is attributed

Crystals, 2016 A rigorous method for obtaining the diffraction patterns of quasicrystals is presented. Diffraction patterns are an essential analytical tool in the study of quasicrystals, since they can be used to determine their photonic resonances.

Quasicrystals in a monodisperse system [PDF]
Physical Review E, 1999 We investigate the formation of a two-dimensional quasicrystal in a monodisperse system, using molecular dynamics simulations of hard sphere particles interacting via a two-dimensional square-well potential. We find that more than one stable crystalline phase can form for certain values of the square-well parameters.

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 Materials Research and Technology, 2019 Icosahedral Al65Cu23Fe12 and decagonal Al73Cu11Cr16 quasicrystalline powders were synthesized by the mechanical alloying and subsequent annealing. Morphology evolution at mechanical alloying of Al-based powders was found to be determined by competition ...

Where the Mineral Kingdom Might Hide New Forms of Matter
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract Mineralogy has traditionally classified matter primarily through local chemistry and diffraction symmetry. But some physically distinct states of matter differ neither principally in composition nor in obvious diffraction symmetry; they differ in how fluctuations behave over very large distances.

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.
