  2. X-ray diffraction - Wikipedia

    en.wikipedia.org/wiki/X-ray_diffraction

    As each crystal is randomly oriented in the beam, hundreds of thousands of individual diffraction images must be collected in order to get a complete data set. This method, serial femtosecond crystallography , has been used in solving the structure of a number of protein crystal structures, sometimes noting differences with equivalent ...

    en.wikipedia.org/wiki/Guilty_Gear_Xrd

    The game is set in 2187, one year after its predecessor, Guilty Gear 2: Overture. [14]Starting in Sign ' s storyline, the first part is set in arcade mode (episode mode in Revelator/REV2) through each characters' own storyline, besides Elphelt, and focuses on Ramlethal Valentine's arc, while the second part of the storyline is set after arcade mode's storyline on the console version, focusing ...

  4. 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.

    The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style. In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text .

  6. X-ray microscope - Wikipedia

    en.wikipedia.org/wiki/X-ray_microscope

    XM-1 uses an X-ray lens to focus X-rays on a CCD, in a manner similar to an optical microscope. XM-1 held the world record in spatial resolution with Fresnel zone plates down to 15 nm and is able to combine high spatial resolution with a sub-100ps time resolution to study e.g. ultrafast spin dynamics.

  7. Powder diffraction - Wikipedia

    en.wikipedia.org/wiki/Powder_diffraction

    where the magnitude of the scattering vector q is in reciprocal lattice distance units, N is the number of atoms, f i (q) is the atomic scattering factor for atom i and scattering vector q, while r ij is the distance between atom i and atom j. One can also use this to predict the effect of nano-crystallite shape on detected diffraction peaks ...

  9. Tier list - Wikipedia

    en.wikipedia.org/wiki/Tier_list

    Higher tiers represent a more favorable ranking. The letters are inspired by grading in education, [1] especially in Japanese culture, which may include an 'S' grade. A tier list is a concept originating in video game culture where playable characters or other in-game elements are subjectively ranked by their respective viability as part of a list.
