Unravelling friction anisotropy by atomic force microscopy. [PDF]
J MicroscAbstract Friction plays a crucial role in both natural phenomena, from the flow of blood cells to earthquakes, and technological applications, from car engines to wind turbines. One of the most fundamental aspects of tribology is friction anisotropy, that is, the dependence of the friction force vector on the direction of sliding.

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

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 ...

Defects in Static Elasticity of Quasicrystals
Crystals, 2017 A review on mathematical elasticity of quasicrystals is given. In this review, the focus is on various defects of quasicrystals. Dislocation and crack are two classes of typical topological defects, while their existence has great influence on the ...

2D honeycomb transformation into dodecagonal quasicrystals driven by electrostatic forces
Nature Communications, 2022 Quasicrystals are perfectly ordered crystals lacking translational symmetry. Here the authors unravel the formation mechanism of two-dimensional dodecagonal quasicrystals that arise from systematic modifications of a hexagonal honeycomb structure.

Data-Driven Design and Fabrication of Heat-Resistant, Ultrastrong, Lightweight Aluminum-Based Entropy Alloy by Additive Manufacturing. [PDF]
Adv Sci (Weinh)A data‐driven strategy integrating quantum machine learning (QML) and high‐throughput computing overcomes hot‐cracking limitation to design a novel lightweight aluminum‐based entropy alloy for additive manufacturing. The fabrication transforms brittle intermetallics into deformable hierarchical nanostructures, yielding ultrastrong strength (>1 GPa) and

Formation of a single quasicrystal upon collision of multiple grains
Nature Communications, 2021 Quasicrystals exhibit long-range order without periodicity. The authors report an approach for quasicrystal fabrication and show through in situ imaging and corresponding simulations the formation of a single decagonal quasicrystal arising from ...

Journal of Research of the National Institute of Standards and Technology, 2001 The discretely diffracting aperiodic crystals termed quasicrystals, discovered at NBS in the early 1980s, have led to much interdisciplinary activity involving mainly materials science, physics, mathematics, and crystallography. It led to a new understanding of how atoms can arrange themselves, the role of periodicity in nature, and has created a new ...
