Shear displacement gradient in X-ray Bragg coherent diffractive imaging
Journal of Synchrotron Radiation, 2022 Bragg coherent X-ray diffractive imaging is a cutting-edge method for recovering three-dimensional crystal structure with nanoscale resolution. Phase retrieval provides an atomic displacement parallel to the Bragg peak reciprocal lattice vector.

Multiple stopbands and wavefield asymmetry of surface water waves in non-Bragg structures
AIP Advances, 2021 In this paper, we use laboratory wave tank experiments to study the effect of asymmetry and defects on the bandgaps of surface water waves and use the finite element numerical method to validate our results.

Bayesian non-parametric Bragg-edge fitting for neutron transmission strain imaging [PDF]
The Journal of Strain Analysis for Engineering Design, 2020 Energy resolved neutron transmission techniques can provide high-resolution images of strain within polycrystalline samples allowing the study of residual strain and stress in engineered components. Strain is estimated from such data by analysing features known as Bragg-edges for which several methods exist.

Clear-Air Bragg Scattering Observed above the Convective Boundary Layer in the Morning
Remote Sensing, 2023 Reflected waves have been frequently observed via weather radar, even during sunny, cloudless days. Additionally, it is recognized that turbulence and biological scatterers can also dominate the scattering process.

Neutron strain tomography using Bragg-edge transmission
International Journal of Materials Research, 2012 AbstractPredicting the fatigue lifetime of components relies on a knowledge of the residual elastic strain present throughout the bulk of the material. Non-destructively mapping the complete strain distribution throughout large volumes presents significant practical challenges.
