Matching Trace Element Distribution to Mineralogical Phases in Ancient Biotechnology-Derived Metallic Salts: a Multimodal Analysis
Sumera Rehman, Spyridon Panagiotopoulos, Georgios E Christidis +4
Conventional X-ray fluorescence (XRF) and X-ray diffraction (XRD) analysis applied to the investigation of ancient metal salts used as pigments and/or therapeutics provide bulk ave…
Material identification using laboratory X-ray beam tracking: quantitativeness and signal-to-noise ratio requirements
Sumera Rehman, Ashkan Ajeer, Connor Darling +3
Simultaneous structural and elemental characterisation of a specimen in a non-destructive manner is an instrumental approach with applications in a variety of fields including ener…
Retrieval of multiple fibre orientations using X-ray dark-field signal modelling
Lorenzo Massimi, Michela Fratini, Shashidhara Marathe +4
Dark-field imaging is widely used to infer fibre orientation from signal modulation as a function of sample orientation. However, current X-ray dark-field retrieval methods are res…
Quantitative phase nano-imaging with a laboratory source
Luca Fardin, Chris Armstrong, Alberto Astolfo +8
Investigating the structure of matter at the nanoscale non destructively is a key capability enabled by X-ray imaging. One of the most powerful nano-imaging methods is X-ray ptycho…
Microfluidic gratings for X-ray Phase Contrast Imaging
Alessandro Rossi, Francesco Coccimiglio, Antonio Ferraro +8
Fabrication of X-ray gratings has surged in the last two decades thanks to their vast employment in X-ray Phase Contrast Imaging, an imaging technique able to boost X-ray sensitivi…
Laboratory-based x-ray microtomography with directional dark-field sensitivity
Carlos Navarrete-Leon, Alvaro Jose Gonzalez-Grajales, Harry Allan +9
We demonstrate dark-field x-ray microtomography in a compact, laboratory-based system capable of resolving attenuation, phase, and anisotropic scattering signals with micrometer-sc…
Sampling requirements in near-field ptychography
L. Fardin, Y. Pulnova, T. Parkman +10
Ptychography is a robust lensless form of microscopy routinely used for applications spanning life and physical sciences. The most common ptychography setup consists in using a det…
Electron volt energy resolution with ptychography using a broadband continuum spectrum
Silvia Cipiccia, Wiebe Stolp, Luca Fardin +6
Ptychography is a scanning coherent diffraction imaging technique successfully applied in the electron, visible and x-ray regimes. One of the distinct features of ptychography with…
