crystal diffraction

crystal diffraction

[′krist·əl di′frak·shən]
(solid-state physics)
Diffraction by a crystal of beams of x-rays, neutrons, or electrons whose wavelengths (or de Broglie wavelengths) are comparable with the interatomic spacing of the crystal.

For all samples, the crystal diffraction peaks corresponding to Ca12Al14O33 phase, while the CaAl-900-10.0% sample remained with the presence of few diffraction peaks owing to the CaO crystal phase [14], suggesting that the extra unreacted Ca species could be transferred to form calcium oxide after the calcination process [20].
iodinea crystal diffraction patterns (see Table 1), with only the b parameter varying significantly.
As shown in Figure 3A, the diffraction peak of compound 1 is in good agreement with that of the simulated one based on the single crystal diffraction data, indicating the pure phase of the obtained samples.

In the early 1990s, a crystal diffraction instrument was developed at the National Institute of Standards and Technology (NIST) for the accurate comparison of crystal lattice spacing values.
In the region associated with the neck drawing, the amorphous halo shows concentrated patterns of crystal diffraction planes, which included the equatorial (010), the meridional (002) and six other diffractions off the equator.
The author explores crystal structure and crystal diffraction, crystal binding and elastic constants, atomic vibrations and lattice specific heat, free electrons theory and simple metals, and many other related subjects.
In phase II, MiTeGen will develop automated bench-top devices that provides faster, safer and more reproducible crystal cooling, and that will allow for a more systematic optimization of crystal diffraction to achieve the highest resolution molecular structures possible.
With increasing content of lithium chloride, the intensity of [gamma]-form crystal diffraction peak increased first and then decreased, which illustrated that the proportion of PA6 [gamma]-form crystal phase increased with lithium chloride content increasing in a certain range.
The presence of broad crystal diffraction peaks indicate that the thin films deposited on the substrates are of nano-sizes (Gosh et al., 2005; Oladeji and Chow, 2005).
EntryLevel Homelab is a single crystal diffraction system for both crystal screening and routine structure determination.
