Characterization and application of Bragg edge transmission imaging for strain measurement and crystallographic analysis on the IMAT beamline

Characterization of Bragg edge transmission imaging on the new IMAT beamline at the ISIS pulsed neutron source is performed, and application of the technique is demonstrated. Bragg edge transmission is capable of producing accurate strain maps with high spatial resolution, and spatially resolved texture information, non-destructively.

Aqua­rium: an automatic data-processing and experiment information management system for biological macromolecular crystallography beamlines

Aqua­rium is an automatic data processing and experiment information management system for synchrotron radiation source MX beamlines. Aqua­rium is designed to automatically process datasets from data reduction to model building, and results presentation. Users can monitor and inspect the data processing results from the Aqua­rium website.

Understanding of stress and its correlation with microstructure near layer continuous limit in nano-scaled multilayer

Evolution of residual stress and its correlation with microstructure are investigated systematically in nano-scaled periodic W/B4C X-ray multilayers (MLs) as a function of individual layer thicknesses in ultra-thin limit (~0.4–2 nm). It is observed that the physical properties of materials, interfacial morphology and residual stress in film undergo a significant modification as the layer thickness varies from continuous to quasi-discontinuous regime, and are explained using a model of mechanism of film growth.

Crystal structure, morphology and formation mechanism of a lead dioxide, γ-PbO2

The crystal structure of a novel phase of lead dioxide, γ-PbO2 forming nanosheets, is identified by energy dispersive spectroscopy microanalysis, transmission electron microscopy and electron microdiffraction. On the basis of the symmetry analysis, the hexagonal-base prismatic shape is explained and a mechanism of formation is proposed.

Anomalous neutron scattering `halo' observed in highly oriented pyrolytic graphite

An unexpected ring in the scattering pattern of highly oriented pyrolytic graphite (HOPG) was observed, which arises from the unique structural and dynamic features of HOPG. A possible interpretation by multiple scattering including elastic and inelastic processes is proposed.

Facile synthesis of novel antimony selenide nanocrystals with hierarchical architecture by physical vapor deposition technique

A new method of calculating interatomic spacing: the equal-ratio method

A new method of calculating interatomic spacing has been proposed. The new method does not require any auxiliary illustration.

Free-film small-angle neutron scattering: a novel container-free in situ sample environment with minimized H/D exchange

A free-film sample environment for neutron scattering, particularly useful for in situ small-angle neutron scattering, is presented, providing a sample area of up to 7 × 20 mm and an average thickness of 500 µm. The instrumental background is reduced by 37% compared with standard Hellma cells, and a helium jacketing of the entire setup provides a minimized H/D exchange with the humidity from air.

A direct approach to estimate the anisotropy of protein structures from small-angle X-ray scattering

In this work, a Guinier-like approximation to directly estimate the anisotropy of molecules in solution from their small-angle X-ray scattering intensity around the origin is developed. This approach provides deeper insight into a molecule's structure than the traditional Guinier RG estimation and can be used in ab initio reconstruction methods to provide better initialization strategies.

An electrochemical cell for operando bench-top X-ray diffraction

An X-ray transparent electrochemical cell with dense glassy carbon windows (Sigradur-G) for operando bench-top X-ray diffraction in reflection geometry is demonstrated.
