    improve energy and material use; facilitate continuous processing; Currently NIR spectroscopy applications dominate the PAT projects. A possible next-generation solution is Energy Dispersive X-Ray Diffraction (EDXRD). [4] For a detailed review of PAT tools see Scott, [5] or Roggo. [6] For an example of application see Gendre. [7]

  3. Specific dynamic action - Wikipedia

    en.wikipedia.org/wiki/Specific_dynamic_action

    Specific dynamic action (SDA), also known as thermic effect of food (TEF) or dietary induced thermogenesis (DIT), is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage. [1]

  4. 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 ...

  5. Grazing incidence diffraction - Wikipedia

    en.wikipedia.org/wiki/Grazing_incidence_diffraction

    Reflection high-energy electron diffraction (RHEED), where electrons of relatively high energy diffract at small angles from a surface. RHEED is used to interrogate surface structure. [1] [2] Surface X-ray diffraction (SXRD), which is similar to RHEED but uses X-rays, and is also used to interrogate surface structure. [3]

  6. Energy-dispersive X-ray diffraction - Wikipedia

    Energy-dispersive X-ray diffraction (EDXRD) is an analytical technique for characterizing materials. It differs from conventional X-ray diffraction by using polychromatic photons as the source and is usually operated at a fixed angle. [1] With no need for a goniometer, EDXRD is able to collect full diffraction patterns very quickly.

  7. 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 ...

  8. Extended X-ray absorption fine structure - Wikipedia

    en.wikipedia.org/wiki/Extended_X-ray_absorption...

    XAS is an interdisciplinary technique and its unique properties, as compared to x-ray diffraction, have been exploited for understanding the details of local structure in: glass, amorphous and liquid systems; solid solutions; doping and ionic implantation of materials for electronics; local distortions of crystal lattices; organometallic compounds

    Kick's law, which related the energy to the sizes of the feed particles and the product particles; [5] Bond's law , which assumes that the total work useful in breakage is inversely proportional to the square root of the diameter of the product particles, [implying] theoretically that the work input varies as the length of the new cracks made ...
