Materials Data creates JADE software used to collect, analyze, and simulate XRD data and solve issues in an array of materials science projects. In 2020, the ICDD and the Cambridge Crystallographic Data Centre, which curates and maintains the Cambridge Structural Database, announced a data partnership.
Rietveld refinement is a technique described by Hugo Rietveld for use in the characterisation of crystalline materials. The neutron and X-ray diffraction of powder samples results in a pattern characterised by reflections (peaks in intensity) at certain positions.
These and other imperfections may also result in peak shift, peak asymmetry, anisotropic peak broadening, or other peak shape effects. [3] If all of these other contributions to the peak width, including instrumental broadening, were zero, then the peak width would be determined solely by the crystallite size and the Scherrer equation would apply.

The peak positions are predicted by the Moseley's law with accuracy much better than experimental resolution of a typical EDX instrument. To stimulate the emission of characteristic X-rays from a specimen a beam of electrons or X-ray is focused into the sample being studied.
X-ray powder diffraction of Y 2 Cu 2 O 5 and Rietveld refinement with two phases, showing 1% of yttrium oxide impurity (red tickers). Powder diffraction is a scientific technique using X-ray , neutron , or electron diffraction on powder or microcrystalline samples for structural characterization of materials. [ 2 ]
Sun Peaks Resort is an ski resort located in Sun Peaks, British Columbia, Canada, 56.6 km (35.2 mi) northeast of Kamloops. [ 1 ] The summit of the ski area is at an elevation of 2,080 m (6,820 ft), with an 882 m (2,894 ft) vertical rise from the base of the peak.
The peaks' positions in the Patterson function are the interatomic distance vectors and the peak heights are proportional to the product of the number of electrons in the atoms concerned. Because for each vector between atoms i and j there is an oppositely oriented vector of the same length (between atoms j and i ), the Patterson function ...
