Decagonal quasicrystals [PDF]

open access: yes, 1989
Following the discovery of two dimensional quasicrystals in rapidly solidified Al-Mn alloys by us and L. Bendersky in 1985, a number of fascinating studies has been conducted to unravel the atomic configuration of quasicrystals with decagonal symmetry. A

Dynamics of quasicrystals [PDF]

open access: yes, 2014
International audienceThe (lattice) dynamics of quasicrystals differs in many aspects from that of lattice periodic systems. This they have in common with other aperiodic crystals.

Dual-band topological Bott insulators in Ammann–Beenker-tiling square photonic quasicrystals

open access: yesJPhys Photonics
In this work, we study topological states in Ammann–Beenker-tiling photonic quasicrystals made of magneto-optical materials. While conventional topological states in photonic systems with crystalline symmetry are characterized by topological invariants ...

Dodecagonal quasicrystals: Construction of 2D lattices and demonstrations using laser pointers

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2022
Photographic slides of an aperiodic dodecagonal tiling were used as two-dimensional diffraction gratings to describe and demonstrate the basic properties of dodecagonal quasicrystals. This paper complements our earlier publication on Penrose (decagonal)

Mechanical Reinforcement of Polymer Nanocomposites with Different Network Structure of Polymer Grafted Nanoparticles

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Due to the different conformation structures of the grafting chains on the surface of silica, the nanoparticles contact each other by brush chains and bridge into a polymer‐mediated nanoparticle network in HDPE14K/HDPE1K‐g‐SiO2 PNCs, resulting in a more significant modulus reinforcement than that of PP370K/PP90K‐g‐SiO2 PNCs with a soft interfacial ...

Isotropic and anisotropic physical properties of quasicrystals [PDF]

open access: yes, 2006
Since quasicrystals have positional and orientational long-range order, they are essentially anisotropic. However, the researches show that some physical properties of quasicrystals are isotropic.

Quantitative analysis of facet growth during directional solidification of salol

open access: yesActa Crystallographica Section B, Volume 82, Issue 2, Page 143-153, April 2026.
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 ...
