Self Assembly of Soft Matter Quasicrystals and Their Approximants [PDF]

, 2011
The surprising recent discoveries of quasicrystals and their approximants in soft matter systems poses the intriguing possibility that these structures can be realized in a broad range of nano- and micro-scale assemblies.

New group of stable icosahedral quasicrystals: structural properties and formation conditions [PDF]

, 2003
Structural studies on the icosahedral quasicrystals in Zn-Mg-Sc, Cu-Ga-Mg-Sc, and Zn-Mg-Ti alloys as well as their corresponding 1/1 cubic approximants, have revealed that these quasicrystals belong to a new structural group similar to Cd-based ...

Superior Performance and Catalytic Mechanism of an Icosahedral Quasicrystal Al-Cu-Fe in CO₂ Reduction to CO. [PDF]

ChemSusChem
Icosahedral quasicrystal Al63Cu25Fe12 (iQC) is employed as a high‐performance catalyst for CO2‐to‐CO conversion. The iQC exhibits superior CO2 conversion compared with its crystalline counterparts. Density functional theory calculations reveal that abundant icosahedral clusters within iQC effectively lower the reaction barrier, elucidating the origin ...

Heptagonal quasicrystals: Construction of 2D lattices and demonstrations using laser pointers – Concluding part

Macedonian Journal of Chemistry and Chemical Engineering, 2023
Photographic slides of an aperiodic heptagonal tiling were used as two-dimensional diffraction gratings (as a standard approach) to describe and demonstrate the basic properties of dodecagonal quasicrystals.

Tetracoordinated quasicrystals [PDF]

Physical Review B, 1991
Current model networks for amorphous Ge contain five-membered rings and pentagonal dodecahedra to explain why in the radial distribution function the third peak of the diamond structure is missing. By presenting an algorithm based on a decoration of the three-dimensional Penrose quasilattice, we prove that this local pentagonal symmetry can be extended

On the Constitutive Modelling of Piezoelectric Quasicrystals

Crystals, 2023
Quasicrystals endowed with piezoelectric properties belong nowadays to novel piezoelectric materials. In this work, the basic framework of generalized piezoelectricity theory of quasicrystals is investigated by providing an improvement of the existing ...

INTERACTIONS IN QUASICRYSTALS [PDF]

International Journal of Modern Physics B, 2000
Although the effects of interactions in solid state systems still remains a widely open subject, some limiting cases such as the three dimensional Fermi liquid or the one-dimensional Luttinger liquid are by now well understood when one is dealing with interacting electrons in periodic crystalline structures.

Disclinations in quasicrystals [PDF]

Physical Review Letters, 1987
The most significant feature in the transition from the quasicrystalline to the amorphous state is the loss of long-range bond-orientational order. Disclinations are candidates for elementary excitations which destroy angular correlations. Generalizing the topological defect classification, we investigate point singularities in two-dimensional ...

Topological critical states and anomalous electronic transmittance in one-dimensional quasicrystals

Physical Review Research, 2021
Due to the absence of periodic length scale, electronic states and their topological properties in quasicrystals have been barely understood. Here, we focus on one-dimensional quasicrystals and reveal that their electronic critical states are ...
