Ab initio structure determination from X-ray powder diffraction data [PDF]

open access: yes, 2015
Many important crystalline solids cannot be prepared in the form of single crystals of sufficient size and quality for single crystal X-ray diffraction studies, and in such cases it is essential that structural information can be extracted from powder ...

Analysis on the Growth and Characterization of a Non-linear Optical Single Crystal: L-Cystine Dihydrobromide [PDF]

open access: yesMaterials Research, 2015
Nonlinear optical single crystals of L-cystine dihydrobromide (LCHB) have been grown by slow evaporation method. Single crystal X-ray diffraction analysis revealed the crystal system and lattice parameter values.

N′-[(E)-4-Methylbenzylidene]pyridine-4-carbohydrazide monohydrate

open access: yesIUCrData, 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.

Methyl 8-oxo-2-phenyl-1-oxaspiro[4.5]deca-2,6,9-triene-3-carboxylate

open access: yesIUCrData, 2016
The title compound, C17H14O4, is a 5/6 spiro-ring fused system, where the five- and six-membered rings are inclined to one another by 89.79 (5)° at the spiro-carbon. In the crystal, non-classical C—H ... O hydrogen bonds form inversion dimers and connect

Bragg Diffraction Imaging of CdZnTe Single Crystals

open access: yesJournal of Electronic Materials, 2020
A high-quality CdZnTe single crystal has been imaged with micrometer resolution using monochromatic x-ray Bragg diffraction at the bending magnet (BM)-05 beamline of the European Synchrotron Radiation Facility. Since this material is used to produce substrates for the epitaxial growth of infrared sensitive HgCdTe photon detectors, imaging the defects ...

Improved Solubility and Dissolution Rate of Ketoprofen by the Formation of Multicomponent Crystals with Tromethamine

open access: yesCrystals, 2022
This study aims to improve the dissolution rate of ketoprofen by preparing multicomponent crystals with tromethamine. The multicomponent crystals (equimolar ratio) of ketoprofen and tromethamine were prepared by the solvent co-evaporation method.

Single Crystal Pulsed Neutron Diffraction [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 1987
Diffraction data from single crystals is obtained using the white-beam, stationary crystal, Laue technique. Separation of orders of the same reflection, which therefore fall on the same spot on the detector, is by their different times of arrival. The geometry of diffraction, the resolution of time-of-flight (TOF) diffractometers and their design is ...

Single Crystal Diffraction Distraction [PDF]

open access: yesThe Vernal Pool, 2019
Author(s): Robinson, Matthew | Abstract: There is a possibility this illustrates electron diffraction through the (1 1 2) diagonal direction in of the tetragonal crystal structure of Bismoclite. I also think it looks neat.
