Quantitative analysis of facet growth during directional solidification of salol

Acta 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 ...

Strongly localized modes in one-dimensional defect-free magnonic quasicrystals

AIP Advances, 2014
Signal storage in magnonic quasicrystals using a slow spin-wave mode, rather than the quasinormal mode of traditional periodic magnonic crystals, is proposed, which is analogous to the slow light mode in the field of optics.

Planar bilipschitz extension from separated nets

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract We prove that every L$L$‐bilipschitz mapping Z2→R2$\mathbb {Z}^2\rightarrow \mathbb {R}^2$ can be extended to a C(L)$C(L)$‐bilipschitz mapping R2→R2$\mathbb {R}^2\rightarrow \mathbb {R}^2$, and we provide a polynomial upper bound for C(L)$C(L)$. Moreover, we extend the result to every separated net in R2$\mathbb {R}^2$ instead of Z2$\mathbb {Z}

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

JPhys 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

Macedonian 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)

Mechanics of Interfacial Cracks between dissimilar Quasicrystals

, 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

Design and characterisation of photonic quasicrystals from microwave to optical regime

, 2010
Photonic band-gap materials are artificially periodic engineered materials with which we can control and manipulate the electromagnetic radiation. The period photonic crystals are well known and have been studied for the last two decades.

Twists and Turns of Liquid Crystals Unravelled by Small‐Angle Scattering

Small Methods, Volume 10, Issue 3, 9 February 2026.
X‐ray scattering provides valuable insights into material structure and self‐assembly. This review discusses the use of small‐ and wide‐angle X‐ray scattering (SWAXS) as well as grazing incident SWAXS for examining self‐assembled systems, especially liquid crystals.
