A crystal is a regular three-dimensional design and is a consequence of the regular arrangement of the atoms, ions, or molecules of which it is built up. However, most of the solid matter we usually come across hardly shows outward evidence of crystalline form; and this is because it is ...
Fig. 9. Schematic diagram of the arrangement of the atoms in a 40° < 110> tilt boundary in tungsten, derived from a sequence of field-ion microscopy images. The position of the < 110 > common tilt axis in the two grains is indicated. Numbers 1–5 indicate subsequent la...
In summary, we realized the controllable growth of single-atom layered Pt-Mn bimetallic nanoplate through a graphdiyne platform, the space-confined alkyne-rich pores of GDY facilitate the ordered arrangement of Pt and Mn atoms. By carefully controlling the content ratio of these two metal atoms, ...
Further, the atomic arrangement itself may be different (reconstruction). These differences affect the surface Debye temperature as well as the detailed processes involved in the adsorption of vapours or other deposited species. Because the electronic wave-functions are discontinued at the free surface,...
Using a multi-component glass-forming alloy as proof of principle, we quantitatively characterize the short- and medium-range order of the 3D atomic arrangement. We observe that, although the 3D atomic packing of the short-range order is geometrically disordered, some short-range-order structures ...
X-Ray diffraction is a technique used to determine the atomic and molecular structure of materials. Solids have a crystalline structure, which corresponds to a microscopic arrangement of atoms that is repeated periodically. By staking planes, a 3-D structure of specific symmetry can be formed. ...

Combined with atomically resolved energy dispersive X-ray spectroscopy (EDS), which can be used to further check the possible chemical mixing in the GB (Fig. 2c), we ultimately determined the atomic arrangement in the buried GB, as schematically shown in Fig. 2d. Quantitative elemental analysis...
Notably, a polymorphic interface is clearly observed in Fig.2d(marked in Fig.2a); its atomic arrangement of edge regions is different from that of the core regions. In detail, the lattice fringe with interplanar spacing in the shell region is 0.130 nm (slightly smaller than that of Rh ...
