, 2016 Abstract This chapter analyzes the diffraction of X-rays from crystals. The wavelengths of X-rays can be of the same order as the interatomic spacings in crystals. In optics we are familiar with the fact that a collection of equally spaced lines (a line grating) scatters (or diffracts) light at discrete angles relative to an incoming ...

Generation of Uniform X-ray Illumination and Its Application to X-ray Diffraction Microscopy
Photonics, 2022 X-ray diffraction microscopy (XDM) is an established lens-less imaging method extensively practiced at synchrotrons and X-ray free-electron lasers (XFELs). XDM is broadly operated in two different modes: scanning and non-scanning.

Zeolite phi: a physical mixture of chabazite and offretite [PDF]
, 1992 Zeolite Phi is synthesized by two methods reported previously. Results from X-ray powder diffraction and scanning electron microscopy suggest that the materials are physical mixtures of chabazite and offretite; one sample has a small amount of ...

On the diffraction pattern of C60 peapods
, 2004 We present detailed calculations of the diffraction pattern of a powder of bundles of C$_{60}$ peapods. The influence of all pertinent structural parameters of the bundles on the diffraction diagram is discussed, which should lead to a better ...

N′-[(E)-4-Methylbenzylidene]pyridine-4-carbohydrazide monohydrate
IUCrData, 2016 In the title hydrate, C14H13N3O·H2O, the C=N double bond adopts an E conformation and the dihedral angle between the aromatic rings is 16.36 (10)°. In the crystal, N—H...O, O—H...O and O—H...N hydrogen bonds link the components into (001) sheets.

A New 2-Aminospiropyrazolylammonium Cation with Possible Uses in the Topical Areas of Ionic Liquids
MoleculesBased on the fact that 2-aminospiropyrazolinium compounds and structurally related azoniaspiro compounds belong, in a broad sense, to the class of ionic liquids, we have reviewed them and studied their practical applications.

X-ray magnetic diffraction under high pressure
IUCrJ, 2019 Advances in both non-resonant and resonant X-ray magnetic diffraction since the 1980s have provided researchers with a powerful tool for exploring the spin, orbital and ion degrees of freedom in magnetic solids, as well as parsing their interplay.

Time-spliced X-ray Diffraction Imaging
, 2018 Diffraction imaging of non-equilibrium dynamics at atomic resolution is becoming possible with X-ray free-electron lasers. However, there are unresolved problems with applying this method to objects that are confined in only one dimension.
