In addition to the phase identification, the evaluated average domain size, lattice parameters, unit-cell volume, number of unit cells, number of domains, B factor, lattice distortion, and domain surface area are listed in Tables 2 and 3. Notably, the lattice parameter of fcc Ru NPs was ...
Even so, all the atoms of a unit cell do not occupy the entire volume of the unit cell itself, there is always some space (or rather voids) between the atoms (assumed to be spheres). This means that ...
To simulate the HCP-FCC prismatic phase transition, a unit cell of 14√3a × a × 1.583a is selected in the present study, and the x, y, and z axes of the unit cell are set as the ⟨101¯0⟩, ⟨12¯10⟩, and ⟨0001⟩ directions, respectively. It should ...
Topologically, a dislocation is constructed by removing a plane of atoms from a perfect crystal, cutting the plane into two pieces, and reinserting one of them; the dislocation itself is defined by the cut. Dislocations move by slip through a crystal under an applied shear stress, translating ...

Consequently, it is crucial to explore the stability of the adsorption configurations as the number of C atoms increases. The second C atom was adsorbed based on the stable adsorption site of the first C atom, and only the C2 structure with the lowest energy was discussed. The optimized ...
Some single crystals display a phenomenon known as “pinning”, where dislocation motion is impeded by precipitates or atoms in solid solution, forming zigzag patterns. These findings highlight the strong interaction between mobile dislocations and impurities. Based on the chemical composition of these...
Such proof is based on the definition of dislocation and leaves no room for debates such as “the corresponding Burgers vector is zero”, as was claimed by some authors [28,30]. Figure 3. Disconnection in {1012} twin boundary from atomistic simulations. The atoms are coloured according to...
