The nucleation of protein crystals as a race against time with on- and off-pathways

Concurrent aggregation pathways competing with crystal nucleation deplete the concentration of soluble protein by the sequential formation of small-order oligomers and metastable clusters. Off-pathway aggregates also have positive effects on protein crystallization by favoring heterogeneous nucleation.

Grain growth engineering and mechanical properties of physical vapour deposited InSe platelets

The successive development of novel hexagonal microstructure of indium monoselenide (InSe) platelet crystals grown by physical vapor deposition has been elucidated for the first time. The investigations on grain boundary morphology, energy gap and strengthening of the vapor grown crystals which arose due to proper control on microstructures provide pathways to realize their superiority for the fabrication of solar cell devices compared to their counterparts synthesized by other methods.

Accepted 15 May 2017

X-ray topography of subsurface crystal layers

The practical application of the modified Berg–Barrett topographic method in a skew asymmetric pattern of X-ray diffraction is presented. The method is used for the study of the defect structure of Ge and CdTe crystals, InSb/InSb films, and Cd1−xHgxTe/CdTe epitaxial layers after the influence of different external factors (ion implantation, etching, chemical and mechanical treatment).

Accepted 13 May 2017

On some aspects of crystallization process energetics, logistic new-phase nucleation kinetics, crystal size distribution, Ostwald ripening

An intriguing analogy between crystallization process and harmonic oscillation is established. It is argued that the crystallizing system responds to the change in its energetic status according to the well-known Le Châtelier – Braun principle.

An in situ USAXS–SAXS–WAXS study of precipitate size distribution evolution in a model Ni-based alloy

Combined ultra-small-, small- and wide-angle X-ray scattering (USAXS–SAXS–WAXS) provides in situ evaluation of the precipitate size distribution (PSD) and phase structure temporal evolution during heat treatment. A method for extraction of an arbitrary PSD in the presence of interparticle interactions is described and illustrated for study of PSD evolution.

Serial electron crystallography: merging diffraction data through rank aggregation

Rank aggregation is used as an alternative approach for merging serial electron crystallography data. The described algorithm avoids the problem of scaling entirely and is insensitive to errors in the reflection intensities.

Instrumental resolution as a function of scattering angle and wavelength as exemplified for the POWGEN instrument

A fundamental description of the instrument resolution file is elaborated for the angular- and wavelength-dispersive cases of Rietveld refinement, exemplified for the POWGEN instrument. It is shown how to refine the necessary profile function parameters from a dataset measured on a diamond reference sample. The analysis is performed in a two-dimensional refinement space based on convenient variables d and d.

The bulk and surface textures of recrystallized straight-rolled α-uranium foils are established by neutron and X-ray diffraction and discussed relative to the existing literature on α-uranium processing textures.

Interface-sensitive imaging by an image reconstruction aided X-ray reflectivity technique

This article describes interface-sensitive imaging of heterogeneous thin films by an image reconstruction aided X-ray reflectivity technique with an 8 mm-wide parallel beam; the possibility of extracting micro-X-ray reflectivity profiles from the same data collection is discussed.
