Fluorescence imaging ofDictyostelium discoideumwith a hard X-ray nanoprobe

open access: yes, 2022
The preparation and a novel sample environment for X-ray based imaging of freeze-dried Dictyostelium discoideum cells are presented. As a first application a fluorescence imaging experiment with a nanofocused hard X-ray beam has been performed.

Microstructural evolution during sintering of copper particles studied by laboratory diffraction contrast tomography (LabDCT)

open access: yesScientific Reports, 2017
Pressureless sintering of loose or compacted granular bodies at elevated temperature occurs by a combination of particle rearrangement, rotation, local deformation and diffusion, and grain growth.

Imaging diamonds with X-rays [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2009
The various techniques for imaging diamonds with x-rays are discussed: x-radiography, x-ray phase-contrast imaging, x-ray topography, x-ray reciprocal-space mapping, x-ray microscopy; together with the characterization of the crystal defects which these techniques reveal.

Time Resolved Two Dimensional X-Ray Densitometry of a Two Phase Flow Downstream of a Ventilated Cavity [PDF]

open access: yes, 2013
To measure the void fraction distribution in gas-liquid flows, a two-dimensional x-ray densitometry system was developed. This system is capable of acquiring a two-dimensional projection with a 225 cm2 area of measurement through 21 cm of water.

Analysis Strategies for MHz XPCS at the European XFEL

open access: yesApplied Sciences, 2021
The nanometer length-scale holds precious information on several dynamical processes that develop from picoseconds to seconds. In the past decades, X-ray scattering techniques have been developed to probe the dynamics at such length-scales on either ...

X-ray colour imaging [PDF]

open access: yesJournal of The Royal Society Interface, 2007
A prototype X-ray colour imaging system has been assembled using the principle of tomographic energy-dispersive diffraction imaging (TEDDI). The new system has been tested using samples of nylon-6, aluminium powder and deer antler bone. Non-destructive three-dimensional images of the test objects have been reconstructed on a 300 μm scale with an ...

Diagnosing and mapping pulmonary emphysema on X-ray projection images [PDF]

open access: yes, 2013
To assess whether grating-based X-ray dark-field imaging can increase the sensitivity of X-ray projection images in the diagnosis of pulmonary emphysema and allow for a more accurate assessment of emphysema distribution.
