  2. Powder diffraction - Wikipedia

    en.wikipedia.org/wiki/Powder_diffraction

    Powder diffraction is a scientific technique using X-ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials. [2] An instrument dedicated to performing such powder measurements is called a powder diffractometer .

  3. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer ...

  4. X-ray diffraction - Wikipedia

    en.wikipedia.org/wiki/X-ray_diffraction

    X-ray diffraction. X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering, when there is no change in the energy of the waves. The resulting map of the directions of the X-rays far from the sample is called ...

  5. Rietveld refinement - Wikipedia

    en.wikipedia.org/wiki/Rietveld_refinement

    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. The height, width and position of these reflections can be used to determine many ...

  6. X-ray diffraction computed tomography - Wikipedia

    en.wikipedia.org/wiki/X-ray_diffraction_computed...

    X-ray diffraction computed tomography, often abbreviated as XRD-CT, typically refers to the technique invented by Harding et al. [1] which assumes that the acquired data are powder diffraction data. For this reason, it has also been mentioned as powder diffraction computed tomography [7] and diffraction scattering computed tomography (DSCT), [8 ...

  7. Wide-angle X-ray scattering - Wikipedia

    en.wikipedia.org/wiki/Wide-angle_X-ray_scattering

    In X-ray crystallography, wide-angle X-ray scattering (WAXS) or wide-angle X-ray diffraction (WAXD) is the analysis of Bragg peaks scattered to wide angles, which (by Bragg's law) are caused by sub-nanometer-sized structures. [1] It is an X-ray-diffraction [2] method and commonly used to determine a range of information about crystalline materials.

  8. Diffractometer - Wikipedia

    en.wikipedia.org/wiki/Diffractometer

    There are several types of X-ray diffractometer, depending on the research field (material sciences, powder diffraction, life sciences, structural biology, etc.) and the experimental environment, if it is a laboratory with its home X-ray source or a Synchrotron. In laboratory, diffractometers are usually an "all in one" equipment, including the ...
