Phase Space Considerations for a microSAXS Beamline Located on a Diamond Laue Side-Bounce Monochromator

open access: yesInstruments, 2020
Flux as well as spatial and angular resolution for a microbeam small-angle X-ray scattering set-up, comprising Laue optics and multiple focusing elements are modeled within five-dimensional phase space analysis.

IXPE Observations of the Quintessential Wind-accreting X-Ray Pulsar Vela X-1

open access: yesThe Astrophysical Journal Letters, 2023
The radiation from accreting X-ray pulsars was expected to be highly polarized, with some estimates for the polarization degree of up to 80%. However, phase-resolved and energy-resolved polarimetry of X-ray pulsars is required in order to test different ...

A Variable Selection Procedure for X-ray Diffraction Phase Analysis [PDF]

open access: yesApplied Spectroscopy, 2007
The X-ray diffraction method has been widely used for qualitative and quantitative phase abundance analysis of crystalline materials. We propose the use of partial least squares when building the calibration model for a quantitative phase analysis based on X-ray diffraction spectra.

Quantitative Phase Analysis by X-ray Diffraction—Doping Methods and Applications

open access: yesCrystals, 2020
X-ray powder diffraction is an ideal technique for the quantitative analysis of a multiphase sample. The intensities of diffraction lines of a phase in a multiphase sample are proportional to the phase fraction and the quantitative analysis can be ...

Investigation of the Corrosion Process by X-Ray Phase Analysis

open access: yesTexas Journal of Medical Science, 2023
This article presents an assessment of corrosion processes by X-ray phase analysis and the inhibitory ability of inhibitors using powder diffractometry (X-ray phase analysis) and scanning electron microscopy.

A bibliometric and social network analysis perspective of X‐ray phase‐contrast imaging in medical imaging

open access: yesJournal of Medical Radiation Sciences, 2022
Introduction Phase‐contrast imaging (PCI) is a novel technology that can visualise variations in X‐ray refraction (phase contrast) in addition to differences in X‐ray attenuation (absorption contrast).

Imaging of metastatic lymph nodes by X-ray phase-contrast micro-tomography. [PDF]

open access: yesPLoS ONE, 2013
Invasive cancer causes a change in density in the affected tissue, which can be visualized by x-ray phase-contrast tomography. However, the diagnostic value of this method has so far not been investigated in detail.
