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...
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 ...
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,...
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. ...
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 ...

The chemical behavior of an element is governed by the number and arrangement of its electrons in relation to its nuclear charge (atomic number). Because these quantities are identical for all isotopes of a given element, they are generally considered to exhibit identical chemical properties. Howeve...
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...
1. This suggests that it is the disordered atomic arrangement that gives rise to the Invar effect in BMGs, and that it is a combination of the short-ranged atomic potentials and the long-ranged magnetic interaction that enables the anomalously low CTE below their Curie temperature. Here we ...
