The index identifies the strongest three lines in the X-ray diffraction pattern of some 1,300 crystalline compounds, the chemical names and symbols of which are as given by the various sources.

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 ...

The most common application of XRD, Phase Analysis seeks to answer the fundamental question we can ask of a material: 'what is it?' We compare diffraction patterns against the 2014 edition of the ...
