Morphological and Crystallographic Characteristics of α Structure in a Low-Carbon Iron–Nickel Alloy
Crystals, 2018 The features of α (body-centered cubic) structures were investigated in a low-carbon multicomponent alloy from morphological and crystallographic perspectives.

Cosmic Crystallography in Compact Hyperbolic Universes [PDF]
arXiv, 1998 We try to apply the cosmic crystallography method of Lehoucq, Lachieze-Rey, and Luminet to a universe model with closed spatial section of negative curvature. But the sharp peaks predicted for Einstein-de Sitter closed models do not appear in our hyperbolic example.

Serial protein crystallography in an electron microscope
Nature Communications, 2019 Serial X-ray crystallography at free-electron lasers allows to solve biomolecular structures from sub-micron-sized crystals. However, beam time at these facilities is scarce, and involved sample delivery techniques are required.

Advanced Sustainable Systems, EarlyView.The measured infrared spectrum of lithium‐sodium orthoborate ((Li0.5Na0.5)3BO3) is shown by first principle calculations to be made up of contributions originating from the mixed alkali‐metal orthoborate Li5Na4B3O9, pyroborate Li2Na2B2O5 and carbonate LiNaCO3, showcasing the important effect of carbon dioxide absorption on the structural make‐up of the

Crystals, 2015 The storage of hydrogen is considered as the bottleneck in the implementation of portable fuel cell power generating systems. The necessary experimental studies to discover and develop appropriate storage materials are always time-limited.

Automatic physical phasing X-ray crystallography [PDF]
arXiv, 2004 Phase invariants are important pieces of information about the atomic structures of crystals. There are several mathematical methods in X-ray crystallography to estimate phase invariants. The multi-wave diffraction phenomenon offers a unique opportunity of physically measuring phase invariants.

Advanced Theory and Simulations, EarlyView.Analytic morphing of wurtzite nanowire cross sections to arbitrary shapes yields numbers of nanowire atoms, of bonds between these and of nanowire interface bonds, plus the nanowire cross section area. The ratios of above variables help to interpret any spectroscopic nanowire data which depend on diameter and cross section shape, and can be applied to ...

The Evolution and the Advantages of MicroED
Frontiers in Molecular Biosciences, 2018 MicroED is a method which combines cryo-EM sample preparation and instrumentation, with electron and X-ray crystallography data analysis, and it has been employed to solve many protein crystal structures at high resolution.

The Topology of the Unitary Dual of Crystallography Groups [PDF]
arXivWe provide a procedure for generating the irreducible representations of crystallography groups in any dimension. We also furnish a strategy to investigate the topology of the unitary dual of a crystallography group using sequences of matrices. All irreducible representations (up to unitary equivalence) of the dimension 3 crystallography group 90 and ...
