  2. Pole figure - Wikipedia

    en.wikipedia.org/wiki/Pole_figure

    A Wulff net is used to read a pole figure. The stereographic projection of a trace is an arc. The Wulff net is arcs corresponding to planes that share a common axis in the (x,y) plane. If the pole and the trace of a plane are represented on the same diagram, then we turn the Wulff net so the trace corresponds to an arc of the net;

  3. Energy-dispersive X-ray spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Energy-dispersive_X-ray...

    A detector is used to convert X-ray energy into voltage signals; this information is sent to a pulse processor, which measures the signals and passes them onto an analyzer for data display and analysis. [citation needed] The most common detector used to be a Si(Li) detector cooled to cryogenic temperatures with liquid nitrogen.

  4. Scherrer equation - Wikipedia

    en.wikipedia.org/wiki/Scherrer_Equation

    The Scherrer equation, in X-ray diffraction and crystallography, is a formula that relates the size of sub-micrometre crystallites in a solid to the broadening of a peak in a diffraction pattern. It is often referred to, incorrectly, as a formula for particle size measurement or analysis.

  5. X-ray crystal truncation rod - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystal_truncation_rod

    To obtain high-quality data in X-ray CTR measurements, it is desirable that the detected intensity be on the order of at least [citation needed]. To achieve this level of output, the X-ray source must typically be a synchrotron source. More traditional, inexpensive sources such as rotating anode sources provide 2-3 orders of magnitude less X ...

  6. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    The use of computational methods for the powder X-ray diffraction data analysis is now generalized. It typically compares the experimental data to the simulated diffractogram of a model structure, taking into account the instrumental parameters, and refines the structural or microstructural parameters of the model using least squares based ...

  7. Online Writing Lab - Wikipedia

    en.wikipedia.org/wiki/Online_Writing_Lab

    Purdue University, in West Lafayette, Indiana, launched the first OWL, in 1994. Its OWL is freely available online to all, and includes handouts, specific subject information, resources geared towards students in grades 7–12, [ 1 ] and citation formatting help with MLA, APA and other forms.

  8. Wide-angle X-ray scattering - Wikipedia

    en.wikipedia.org/wiki/Wide-angle_X-ray_scattering

    It is an X-ray-diffraction [2] method and commonly used to determine a range of information about crystalline materials. The term WAXS is commonly used in polymer sciences to differentiate it from SAXS but many scientists doing "WAXS" would describe the measurements as Bragg/X-ray/powder diffraction or crystallography .

  9. Selected area diffraction - Wikipedia

    en.wikipedia.org/wiki/Selected_area_diffraction

    SADP of a single austenite crystal in a piece of steel. Selected area (electron) diffraction (abbreviated as SAD or SAED) is a crystallographic experimental technique typically performed using a transmission electron microscope (TEM).
