  2. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    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 can produce a three-dimensional picture of ...

  3. X-ray lithography - Wikipedia

    en.wikipedia.org/wiki/X-ray_lithography

    X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.

  4. X-ray fluorescence - Wikipedia

    en.wikipedia.org/wiki/X-ray_fluorescence

    X-ray fluorescence. XRF scanning of the Rembrandt -painting Syndics of the Drapers' Guild. A handheld XRF analyzer gun. X-ray fluorescence ( XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.

  5. X-ray - Wikipedia

    en.wikipedia.org/wiki/X-ray

    X-ray. Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays. X-rays ( X-radiation) are a form of high-energy electromagnetic radiation.

  6. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    X-ray optics. X-ray optics is the branch of optics that manipulates X-rays instead of visible light. It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and ...

  7. Texture (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Texture_(chemistry)

    Texture (chemistry) Pole figures displaying crystallographic texture of gamma-TiAl in an alpha2-gamma alloy, as measured by high energy X-rays. [ 1] In physical chemistry [unreliable source?] and materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric ...

  8. X-ray laser - Wikipedia

    en.wikipedia.org/wiki/X-ray_laser

    X-ray laser. An X-ray laser can be created by several methods either in hot, dense plasmas or as a free-electron laser in an accelerator. This article describes the x-ray lasers in plasmas, only. The plasma x-ray lasers rely on stimulated emission to generate or amplify coherent, directional, high-brightness electromagnetic radiation in the ...

  9. Chest radiograph - Wikipedia

    en.wikipedia.org/wiki/Chest_radiograph

    Dx and Sin stand for "right" and "left" respectively. A chest radiograph, chest X-ray ( CXR ), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
