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.

Cation Distribution in Li2CaSiO4:Gd, Pr, Na Uncovered Through Anomalous Diffraction

European Journal of Inorganic Chemistry, Volume 29, Issue 20, 17 July 2026.
Li2CaSiO4 co‐doped with Gd3+ and Pr3+ shows strong blue‐to‐UV‐B up‐conversion. Herein, we explore the doping element distribution in order to discern the reason for the strongly supportive co‐doping effect using high‐resolution Rietveld refinement and multiple‐edge anomalous dispersion measurements.

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 ...

Y4Ni0.71Ag1.29: Expanding the Boundaries of the Gd4RhIn Structure Type

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
A first representative of the Gd4RhIn type with three transition metals. The new ternary compound Y4Ni0.71Ag1.29 has been prepared by arc melting the elements under inert atmosphere. Subsequent annealing at 800°C for 2 weeks yielded crystals of sufficient quality for structure determination by single‐crystal X‐ray diffraction.

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)

Dislocations in icosahedral quasicrystals [PDF]

Chemical Society Reviews, 2012
Dislocations in quasicrystals, as a direct result of the lack of translational symmetry in these materials, possess various salient features. The Burgers vector of a dislocation in an icosahedral quasicrystal is a 6-dimensional vector, which reflects the fact that the dislocation, besides the phonon-type strain field analogous to dislocations in ...

Beyond Single‐Active Sites: The Emergence of High‐Entropy Perovskites in Energy and Environment Catalysis

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
This review examines high‐entropy perovskites (HEPs) as a promising catalyst platform for energy and environmental applications. The focus is on configurational entropy engineering, design and synthesis, and computational understanding. These materials possess tunable active sites, enhanced stability, and improved electronic interactions, leading to ...

Bridging the local configurations and crystalline counterparts of bulk metallic glass by nanocalorimetry

Journal of Materials Research and Technology, 2019
The structural understanding of crystallization in bulk metallic glasses (BMGs) has attracted much attention while rapid crystallization occurring under controllable conditions is less involved.
