  2. 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.

  3. X-ray scattering techniques - Wikipedia

    en.wikipedia.org/wiki/X-ray_scattering_techniques

    This is an X-ray diffraction pattern formed when X-rays are focused on a crystalline material, in this case a protein. Each dot, called a reflection, forms from the coherent interference of scattered X-rays passing through the crystal.

  4. X-ray diffraction - Wikipedia

    en.wikipedia.org/wiki/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 a diffraction pattern.

  5. Powder diffraction - Wikipedia

    en.wikipedia.org/wiki/Powder_diffraction

    Nevertheless, powder X-ray diffraction is a powerful and useful technique in its own right. It is mostly used to characterize and identify phases, and to refine details of an already known structure, rather than solving unknown structures. Advantages of the technique are: simplicity of sample preparation; rapidity of measurement

  6. X-ray spectroscopy - Wikipedia

    en.wikipedia.org/wiki/X-ray_spectroscopy

    X-ray diffraction units were widely used in academic research departments to do crystal analysis. An essential component of a diffraction unit was a very accurate angle measuring device known as a goniometer. Such units were not commercially available, so each investigator had do try to make their own.

  7. X-ray diffraction computed tomography - Wikipedia

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

    X-ray diffraction computed tomography is an experimental technique that combines X-ray diffraction with the computed tomography data acquisition approach. X-ray diffraction (XRD) computed tomography (CT) was first introduced in 1987 by Harding et al. [ 1 ] using a laboratory diffractometer and a monochromatic X-ray pencil beam .

  9. 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 ...
