WebSep 13, 2024 · Real crystals are composed of a mosaic of domains whose misalignment is evaluated by their level of “mosaicity” using X-ray diffraction. In thermo-induced spin-crossover compounds, the crystal may be seen as a mixture of metal centres, some being in the high-spin (HS) state and others in the low spin (LS) state. Since the … WebThe mosaicity of the crystal was anisotropic, with FWHM values of 0.0068, 0.0140 and 0.0046 degrees along the a, b and c axes, respectively. The anisotropic mosaicity analysis indicates that the crystal is most perfect in the direction that corresponds to the favored growth direction of the crystal.
WebApr 1, 2002 · We have reviewed recent advancements in the SiC bulk crystal growth technology.

Time-dependent unit cells, mosaicity and Wilson B factors in cold crystals. When crystals are cooled to ∼140 K or below, vitrified internal solvent immobilizes the protein atoms and the crystal diffraction properties are (in the absence of radiation damage) independent of time. As crystals are warmed from ∼140 to ∼190 K, solvent ...

WebJan 1, 2003 · Disorder can be described as long range or short range. In general long-range disorder in the crystal gives rise to localized effects in reciprocal space and vice versa. 1, 2 For example, crystal mosaicity, which is a large-scale property in real space, causes the localized effect of broadened spots in reciprocal space. Random disorder between ...
