- Model mechanisms in Kikuchi pattern formation from crystals
Version of Record online: 28 MAR 2017 | DOI: 10.1002/crat.201600288
Diffraction patterns from crystals often contain a mixture of different features which can be caused by scattered waves which remain coherent with the incident waves or by waves which have lost some or most of this coherence. By extending the kinematic, single-scattering, model of diffraction to include double-scattering processes, a simple toy model is discussed which illustrates some of the implications of coherence loss in diffraction from crystals.

Interferometry-based diagnostics of transport phenomena around solution-grown inorganic (NaClO3) and organic crystals (hen-egg white lysozyme) are reported. Direct visualization of concentration boundary layers in the form of interferometric fringe deformation indicated towards dominance of convective mode of solute transport in the case of inorganic crystals while the solute transport was seen to be diffusion-dominated for organic crystals. The strength of the transport phenomena have been quantified in the form of non-dimensional parameter, namely Rayleigh numbers for each case.
- Growth of lead iodide single crystals used for nuclear radiation detection of Gamma-rays

Lead iodide (PbI2) has drawn increased interest in room-temperature X-ray and γ-ray detectors in recent years. PbI2 single crystals have been fabricated by vertical Bridgeman method and vertical gradient freezing method for comparison. The crystal grown by vertical gradient freezing method exhibited higher quality with no stress cracks and high infrared transmission rate.
- Understanding charge transfer stacking mode in cocrystals involving Tetrachloro-p-benzoquinone via experimental (SXRD, DSC-TGA, DRS) studies and hirshfeld surfaces analysis

Three charge transfer cocrystals involving Tetrachloro-p-benzoquinone were obtained via evaporation method and investigated by Experimental (SXRD, DSC-TGA, and DRS) studies and Hirshfeld surfaces analysis, the charge transfer stacking mode between donor and acceptor can be affected by the design of electron donor. In this study, two of these cocrystals exhibit face-to-face mixed-stacking mode forming DADDAD chains while the other one adopts separated-stacking mode.
- Quasicontinuum simulation of brittle cracking in single-crystal material

A quantitative evaluation of the precision of the QC model of the classical plate hole problem was undertaken. A certain amount of “ghost” interference was observed at the interface between the atomic and continuum mediums, and the crystal orientation effect of the crack tip atoms was used to analyze the dislocation emission, twinning, void nucleation, and crack propagation in specific grains, as well as the defect evolution by strain-force response.
