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.

Continuous Diffraction of Molecules and Disordered Molecular Crystals [PDF]

open access: yes, 2017
The diffraction pattern of a single non-periodic compact object, such as a molecule, is continuous and is proportional to the square modulus of the Fourier transform of that object. When arrayed in a crystal, the coherent sum of the continuous diffracted

Local order and orientational correlations in liquid and crystalline phases of carbon tetrabromide from neutron powder diffraction measurements [PDF]

open access: yes, 2010
The liquid, plastic crystalline and ordered crystalline phases of CBr$_4$ were studied using neutron powder diffraction. The measured total scattering differential cross-sections were modelled by Reverse Monte Carlo simulation techniques (RMC++ and ...

Crystal structure of 3-methoxycarbonyl-2-(4-methoxyphenyl)-8-oxo-1-azaspiro[4.5]deca-1,6,9-trien-1-ium-1-olate

open access: yesActa Crystallographica Section E, 2014
The title compound, C18H17NO5, was prepared by a synthetic strategy based on the Heck reaction from Morita–Baylis–Hillman adducts. The five-membered ring adopts a slightly twisted conformation on the Ca—Cm (a = aromatic and m = methylene) bond.

High-temperature synthesis, single-crystal X-ray and neutron powder diffraction, and materials properties of Sr3Ln10Si18Al12O18N36 (Ln = Ce, Pr, Nd) [PDF]

open access: yes, 2000
The novel oxonitridoaluminosilicates (sialons) Sr3Ln10Si18Al12O18N36 (Ln = Ce, Pr, Nd) were obtained by the reaction of the respective lanthanide metals with Si(NH)2, SrCO3, and AlN using a radiofrequency furnace at temperatures between 1550–1650°C.

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 ...
