Quantitative 3D Real-Space Analysis of Photonic Supraparticles. [PDF]
Adv MaterThis work shows that through quantitative 3D real‐space analysis, photonic supraparticles can be investigated in detail. By clustering and classifying all particles, structure features can easily be detected, and the internal structure can be quickly investigated. This methodology allows for quick identification of different crystal structures, such as

Primitive icosahedral quasicrystals in ZnMgLi(Dy, Ho, Er, Tm) systems. [PDF]
Acta Crystallogr A Found AdvThe study introduces new primitive icosahedral quasicrystals in Zn–Mg–Li–(Dy, Ho, Er, Tm) systems. Quasicrystals are studied with an X‐ray diffraction technique resolving the local atomic structure.New quasicrystals with rare‐earth elements and Li are synthesized with the self‐flux method. The starting composition involves 62.8 at.% Zn, 28.6 at.% Mg, 3.

Symmetry breaking of dipole orientations on Caspar-Klug lattices
Physical Review Research, 2020 Anisotropic dipole-dipole interaction often plays a key role in biological, soft, and complex matter. For it to induce nontrivial order in the system, there must be additional repulsive interactions or external potentials involved that partially or ...

Symmetry of Magnetically Ordered Quasicrystals [PDF]
, 1998 The notion of magnetic symmetry is reexamined in light of the recent observation of long range magnetic order in icosahedral quasicrystals [Charrier et al., Phys. Rev. Lett. 78, 4637 (1997)].

Origin of icosahedral symmetry in viruses [PDF]
Proceedings of the National Academy of Sciences, 2004 With few exceptions, the shells (capsids) of sphere-like viruses have the symmetry of an icosahedron and are composed of coat proteins (subunits) assembled in special motifs, the T -number structures. Although the synthesis of artificial protein cages is a rapidly developing area of materials science, the design ...

Early-stage bifurcation of crystallization in a sphere
Nature Communications, 2023 Bifurcations in kinetic pathways decide the evolution of a system. An example is crystallization, in which the thermodynamically stable polymorph may not form due to kinetic hindrance.

Dual Cluster Model for Medium-Range Order in Metallic Glasses
Metals, 2021 The atomic structure of medium-range order in metallic glasses is investigated by using molecular dynamics (MD) simulations. Glass formation processes were simulated by rapid cooling from liquid phases of a model binary alloy system of different-sized ...

Criteria for formation of metallic glasses: The role of atomic size ratio [PDF]
, 2003 We consider metallic alloys of Cu*, Cu, and Cu** in which the atoms differ only in their atomic radii and examine how the size ratio affects the local orders in the alloy systems.
