short-range order

short-range order

[′shȯrt ¦rānj ′ȯr·dər]
(physics)
A regularity in the arrangement of atoms in a disordered solid or a liquid in which the probability of a given type of atom having neighbors of a given type is greater than one would expect on a purely random basis.

For the real amorphous C-S-H, the main features of the structure need to be considered, such as long-range disorder, short-range order, calcium silicon ratio (Ca/Si), the layered structure, Qn distribution, and density.
Based on the PA technique, the 1201 and 1311 bond pairs represent the rhombus symmetrical features of short-range order. The FCC structure has the type of 1421 bond pairs, whereas the HCP crystal has the equal number of 1421 and 1422 bond pairs.
Figures 1(b), 1(c), and 1(d) show that with decreased temperature, the first peaks of C-C, C-Si, and Si-Si all become heightened and sharp, which indicates the uniformity of the bond length and the increase in short-range order (SRO) for all kinds of bonds.
Chapters cover making computer crystals, simulating experimental data, correlations and creating short-range order, creating modulations, creating structures with stacking faults, creating domain structures, creating nanoparticles, analyzing disordered structures, and refining disordered structures.

For example, the low bulk density of volcanic ash soil is generally explained by the presence of short-range order minerals and high organic matter content, whereas Miehlich (1991) suggested that this property could be due to isovolumetric weathering.
In the past, researchers regarded the fluctuations as nearly random variations, with a little short-range order reflecting the influence of neighboring regions on each other.
The electron diffraction pattern is shown in Figure 1(f), where an amorphous ring (light-grey ring in the middle of the pattern, marked by a yellow cross) due to short-range order of the local environment is observed in addition to the sharp crystalline reflections.
Various studies report that either short-range order, quasi-long-range order or even long-range order might be established.
As the system crosses from the insulating into the metallic phase, one-dimensional (ID) states (localized on a single chain) evolve into 3D state, which are delocalized over several chains with short-range order and form a disorder metal (9), (10).
Topics include the general chemistry of amphiboles and their structures, classification of amphiboles, new natural and synthetic amphibole compositions, long-range order (including anion incorporation), short-range order in amphiboles, including short-range disorder, non-ambient in situ studies, the synthesis and stability of some end-member amphiboles, the significance of the reaction path in synthesizing single-phase amphiboles of defined compositions, amphiboles in the igneous environment, composition and co-existence of metamorphic amphiboles, trace-element partitioning between amphibole and silicate melt, environmental and health concerns about amphiboles, including regulatory and legal issues, and amphiboles from an historical perspective.
