    In it, geometrical shapes can be made, as well as expressions from the normal graphing calculator, with extra features. [8] In September 2023, Desmos released a beta for a 3D calculator, which added features on top of the 2D calculator, including cross products, partial derivatives and double-variable parametric equations.

  5. Three-dimensional X-ray diffraction - Wikipedia

    en.wikipedia.org/wiki/Three-dimensional_X-ray...

    Three-dimensional X-ray diffraction (3DXRD) is a microscopy technique using hard X-rays (with energy in the 30-100 keV range) to investigate the internal structure of polycrystalline materials in three dimensions.

  6. X-ray crystal truncation rod - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystal_truncation_rod

    X-ray crystal truncation rod scattering is a powerful method in surface science, based on analysis of surface X-ray diffraction (SXRD) patterns from a crystalline surface. For an infinite crystal, the diffracted pattern is concentrated in Dirac delta function like Bragg peaks.
