High-Resolution Scanning X-ray Diffraction Microscopy
A ptychographic imaging method is demonstrated that bridges the gap between CDI and STXM by measuring complete diffraction patterns at each point of a STXM scan.
Probe retrieval in ptychographic coherent diffractive imaging.
Ptychographic X-ray computed tomography at the nanoscale
An X-ray computed tomography technique that generates quantitative high-contrast three-dimensional electron density maps from phase contrast information without reverting to assumptions of a weak phase object or negligible absorption is described.
Anisotropic micro-sphere-based finite elasticity applied to blood vessel modelling
Computational Modelling of Isotropic Multiplicative Growth
The changing mass of biomaterials can either be modelled at the constitutive level or at the kinematic level. This contribution attends on the description of growth at the kinematic level. The…
Reconstructing state mixtures from diffraction measurements
A general analytic approach to the characterization of diffractive imaging systems that can be described as low-rank mixed states is provided and some of the most stringent experimental conditions in ptychography can be relaxed, and susceptibility to imaging artefacts is reduced.

The formation of nanoparticles within the laser-induced cavitation bubble is studied in situ using small angle X-ray scattering with high spatiotemporal resolution and a minor fraction of both species could be detected outside the cavitation Bubble even before its final collapse.
Phase tomography from x-ray coherent diffractive imaging projections.
A method for tomographic reconstruction that works on phase projections that are known modulo 2π, such that the phase unwrapping step is avoided and a simple method to remove undesired constant and linear phase terms on the reconstructions is given.

The main goal of this contribution consists in the development of a remodelling framework for orthotropic continua whereby the underlying symmetry group is incorporated via two fibre families.…
