   en.wikipedia.org/wiki/Coot_(software)

   Coot is free software, distributed under the GNU GPL. It is available from the Coot web site [4] originally at the University of York, and now at the MRC Laboratory of Molecular Biology. Pre-compiled binaries are also available for Linux and Windows from the web page and CCP4, and for Mac OS X through Fink and CCP4. Additional support is ...

3. 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 .

5. Olex2 - Wikipedia

   en.wikipedia.org/wiki/Olex2

   Olex [1] [2] and Olex2 [3] [4] are versatile software for crystallographic research. Olex used to be a research project developed during PhD to implement topological (as connectivity) analysis of polymeric chemical structures and still is widely used around the world. Olex2 is an open source project with the C++ code portable to Windows, Mac ...

6. 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.

7. X-ray scattering techniques - Wikipedia

   en.wikipedia.org/wiki/X-ray_scattering_techniques

   X-ray diffraction, sometimes called Wide-angle X-ray diffraction (WAXD) Small-angle X-ray scattering (SAXS) probes structure in the nanometer to micrometer range by measuring scattering intensity at scattering angles 2θ close to 0°. X-ray reflectivity is an analytical technique for determining thickness, roughness, and density of single layer ...

8. Three-dimensional X-ray diffraction - Wikipedia

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

   Compared with destructive techniques, e.g. three-dimensional electron backscatter diffraction (3D EBSD), [5] with which the sample is serially sectioned and imaged, 3DXRD and similar X-ray nondestructive techniques have the following advantages: They require less sample preparation, thus limiting the introduction of new structures in the sample.

9. 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 ...
