X-ray sources abound around us. They include the following: Natural X-ray sources: Astrophysical X-ray source, as viewed in X-ray astronomy; X-ray background;
X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist, or simply "resist," on the substrate to reach extremely small topological size of a feature.
The first X-ray picture of the Sun from a rocket-borne telescope was taken by John V. Lindsay of the NASA Goddard Space Flight Center and collaborators in 1963. The first orbiting X-ray telescope flew on Skylab in the early 1970s and recorded more than 35,000 full-disk images of the Sun over a 9-month period. [3]
X-Ray is a reference tool, introduced in September 2011, [1] that is incorporated in the Amazon Kindle Touch and later models, Kindle apps for mobile platforms, Amazon Fire tablets, Fire TVs and Amazon Prime Video streaming apps, and the discontinued Fire Phone. On the Kindle, general reference information is preloaded into a small file on the ...
X-ray emission spectroscopy (XES) is a form of X-ray spectroscopy in which a core electron is excited by an incident X-ray photon and then this excited state decays by emitting an X-ray photon to fill the core hole. The energy of the emitted photon is the energy difference between the involved electronic levels.
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.
Camp is an aesthetic and sensibility that regards something as appealing or amusing because of its heightened level of artifice, affectation and exaggeration, [1] [2] [3] especially when there is also a playful or ironic element. [4] [5] Camp is historically associated with LGBTQ culture and especially gay men.
An X-ray image intensifier (XRII) is an image intensifier that converts X-rays into visible light at higher intensity than the more traditional fluorescent screens can. Such intensifiers are used in X-ray imaging systems (such as fluoroscopes) to allow low-intensity X-rays to be converted to a conveniently bright visible light output.
