X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer can produce a three-dimensional picture of ...
X-ray. Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays. X-rays ( X-radiation) are a form of high-energy electromagnetic radiation.
X-ray detector. Acquisition of projectional radiography, with an X-ray generator and an imaging detector. X-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays . Detectors can be divided into two major categories: imaging detectors (such as photographic plates and X-ray film ...
X-ray optics. X-ray optics is the branch of optics that manipulates X-rays instead of visible light. It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and ...
Natural X-ray sources: Astrophysical X-ray source, as viewed in X-ray astronomy. X-ray background. Naturally occurring radionuclides. Artificial X-ray sources. Radiopharmaceuticals in radiopharmacology. Radioactive tracer. Brachytherapy. X-ray tube, a vacuum tube that produces X-rays when current flows through it.
Soft X-ray transients ( SXTs ), also known as X-ray novae and black hole X-ray transients, are composed of a compact object (most commonly a black hole but sometimes a neutron star) and some type of "normal", low-mass star (i.e. a star with a mass of some fraction of the Sun's mass). [1] [2] These objects show dramatic changes in their X-ray ...
Texture (chemistry) Pole figures displaying crystallographic texture of gamma-TiAl in an alpha2-gamma alloy, as measured by high energy X-rays. [ 1] In physical chemistry [unreliable source?] and materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric ...
The observed X-ray background is thought to result from, at the "soft" end (below 0.3 keV), galactic X-ray emission, the "galactic" X-ray background, and, at the "hard" end (above 0.3keV), from a combination of many unresolved X-ray sources outside of the Milky Way, the "cosmic" X-ray background (CXB). The galactic X-ray background is produced ...
