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 ...
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,...
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...[...
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, ...
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...
The electron configuration of an atom corresponds to the manner in which these shells and subshells are filled with electrons on compliance with the Pauli exclusion principle. The periodic table of the elements is penerated by arrangement of the various elements according to valence electron ...
In addition to the forces exerted on atomic dipoles by an external magnetic field, mutual forces exist between the dipoles. Such forces vary widely for different substances. Below a certain transitiontemperaturedepending on the substance, they produce an ordered arrangement of the orientations of the...
The upshot of this is one can theoretically figure out if an alien species is predator or prey just by examining the arrangement of their eyes. Or maybe not. Dr. Luke Campbell makes a strong case for the "carnivors alway have binocular vision" theory to be a big steaming pile of bovine...
