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 ...

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 ...
orderly and repeated pattern that is in contrast to the random and disoedered atomic distribution found in noncrystalline or amorphous materials.Atoms may be represented as solid spheres,and,for crystalline solids,crystal structure is just the spatial arrangement of these s 正在翻译,请等待...[...
The microscopic stresses defined at each atom, or the atomic level stresses, are effective parameters to describe the local variations in the atomic arrangement in liquids and glasses. We have calculated them for model binary alloy systems both in the amorphous and in the crystalline (fcc and bcc...
Above this energy, loss undulations due to the atomic arrangement appear close to the ionised atom, called EXtended Electron Loss Fine Structure (EXELFS). The classification corresponds to XANES and EXAFS measurements of the edge structure as discussed in Chapter 6, and EELS spectra can be ...
Answer: Relative to polymer chains, the difference between configuration and conformation is that conformation is used in reference to the outline or shape of the chain molecule, whereas, configuration refers to the arrangement of atom positions along the chain that are not alterable except by the...
Atomic Arrangement Atoms are arranged in various configurations to form solids. Figure 2.5 shows some of the typical atomic arrangements (lattices). Sign in to download full-size image Figure 2.5.

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, ...
