Diffraction of Neutrons by a Single Crystal
The intensity of neutrons emitted by the nuclear chain reactor has been shown to be sufficiently great to permit the observation of the Bragg reflection of neutrons by a single crystal. A single crystal monochromator has been constructed and used for the investigation of resonances.

The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Accurate crystal structure of ice VI from X-ray diffraction with Hirshfeld atom refinement
Water is an essential chemical compound for living organisms, and twenty of its different crystal solid forms (ices) are known. Still, there are many fundamental problems with these structures such as establishing the correct positions and thermal ...

Single-crystal neutron diffraction
The applications of coherent elastic neutron scattering from single crystals are reviewed, with emphasis on Earth Sciences materials. The peculiar character of the neutron interaction with matter is naturally exploited in a number of typical experiments: (1) the location of light atoms in the presence of heavy atoms in the structure; (2) the ...

The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Redetermination of the crystal structure of NbF4
Single crystals of NbF4, niobium(IV) tetrafluoride, were synthesized by disproportionation of Nb2F5 at 1273 K in a sealed niobium tube, extracted and studied by single-crystal X-ray diffraction.

ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

X-ray Diffraction of Photonic Colloidal Single Crystals [PDF]
We have resolved a great number of Bragg peaks of photonic colloidal single crystals by synchrotron small angle X-ray scattering (SAXS). We find that charge-stabilized colloids form face-centered cubic crystals at all densities up to ∼60 vol %. The colloidal particles are highly ordered on their lattice sites, which confirms that these self-organizing ...

The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
