Using X-ray pulses to illuminate nanoparticles, researchers decode diffraction patterns to construct detailed three-dimensional images. (Illustration: ETH Zürich / Daniela Rupp) In a 2D-XRD experiment ...

A CARBIDE which has a needle-like appearance on a polished and etched cross-section is a common occurrence in hot-rolled 3.25 per cent silicon iron. It is metastable with respect to cementite and ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...

XRD works by directing X-rays onto a crystalline material and analyzing the angles and intensities of the diffracted beams. The atomic planes within the crystal act as a three-dimensional grating, ...

When using conventional X-ray diffraction systems to analyse crystal structures, crystals have to be milled into powders to ensure that the scattering patterns obtained are as uniform as possible.

Initially showcased in 1991, XRD-CT offers a superior approach to characterising the physicochemical composition of intact objects. It has an advantage over traditional X-ray imaging because it ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

The method can predict the structure directly from powder X-ray diffraction patterns, the patterns of X-rays passing through crystals roughly the same size as instant coffee particles. Unlike ...
