  2. 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.

    a) The rate at which frames of video data are scanned on the screen. In an NTSC system, the frame rate is 29.97 frames per second. For PAL, the frame rate is 25 frames per second. b) The number of frames per second at which a video clip is displayed. c) The rate at which frames are output from a video decoding device or stored in memory.

  5. 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 .

  6. X-ray fluorescence - Wikipedia

    en.wikipedia.org/wiki/X-ray_fluorescence

    X-ray diffraction (XRD) is still the most used method for structural analysis of chemical compounds. Yet, with increasing detail on the relation of K β {\displaystyle K_{\beta }} -line spectra and the surrounding chemical environment of the ionized metal atom, measurements of the so-called valence-to-core (V2C) energy region become ...

  7. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    An X-ray diffraction pattern of a crystallized enzyme. The pattern of spots (reflections) and the relative strength of each spot (intensities) can be used to determine the structure of the enzyme. The relative intensities of the reflections provides information to determine the arrangement of molecules within the crystal in atomic detail.
