Inversion domain boundary structure of laterally overgrown c-GaN domains including the inversion from Ga to N polarity at a mask pattern boundary

During polarity-inverted lateral overgrowth, inversion domain boundaries (IDBs) are found to be formed on the energetically less favorable \{11{\overline 2}0\} plane. A model that takes a geometrical factor into consideration can explain this preferential tendency of IDB formation. Computational simulations based on the proposed model turn out to be consistent with experimental results.

Diffraction from twisted nanowires: an helicity revealed by anisotropy

It is shown, using kinematical theory, that the helical nature of twisted nanowires is revealed in X-ray diffraction patterns by either elastic or shape anisotropy.

Accepted 17 September 2018

Upgraded SSRF BL19U2 beamline for small-angle X-ray scattering of biological macromolecules in solution

The upgraded biological small-angle X-ray scattering station at the Shanghai Synchrotron Radiation Facility is equipped with an in-vacuum automated sample loading system, an inline Agilent high-performance liquid chromatography system and a Wyatt light scattering device. The versatile sample environments and easy-to-access remote-control platform make the high-brightness beamline BL19U2 ideally suitable for performing SAXS experiments on biological macromolecules in solution.

Quasielastic neutron scattering of brucite to analyse hydrogen transport on the atomic scale

Quasielastic neutron scattering is applied to analyse the atomic scale hydrogen transport processes occurring within the crystal lattices of hydrous minerals. Two types of transport processes were observed in Mg(OH)2, which has a prototypical layered hydrogen lattice structure.

Accepted 15 September 2018

Limitations of the kinematic approximation in neutron reflectivity measurements for the analysis of bilayers

Neutron reflectivity on metallic superlattices is used to measure the volume expansion induced by deuterium content. The differences between treating the data with simple Gaussian fits and full reflectivity fits using Parratt's recursive method are shown and an explanation is proposed.

Accepted 13 September 2018

A prototype handheld X-ray diffraction instrument

Energy-dispersive X-ray diffraction implemented in a back-reflection geometry has unique characteristics, particularly its insensitivity to sample morphology. The potential to develop a handheld X-ray diffraction instrument based on this technique is explored with the help of a prototype instrument adapted from a handheld X-ray fluorescence device.
