X-ray absorption fine structure (XAFS) is a specific structure observed in X-ray absorption spectroscopy (XAS). By analyzing the XAFS, information can be acquired on the local structure and on the unoccupied local electronic states.
Phase-contrast X-ray imaging or phase-sensitive X-ray imaging is a general term for different technical methods that use information concerning changes in the phase of an X-ray beam that passes through an object in order to create its images. Standard X-ray imaging techniques like radiography or computed tomography (CT) rely on a decrease of ...
X-Ray Spex was an English punk rock band formed in 1976 in London . During their first incarnation (1976–1979), X-Ray Spex released five singles and one album. [1] Their 1977 single " Oh Bondage Up Yours! " and 1978 debut album Germfree Adolescents are widely acclaimed as classic punk releases. [sources 1] The band has briefly reformed ...
Small-angle X-ray scattering ( SAXS) is a small-angle scattering technique by which nanoscale density differences in a sample can be quantified. This means that it can determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes, characteristic distances of partially ordered ...
A cathode-ray tube(CRT) is a vacuum tubecontaining one or more electron guns, which emit electronbeams that are manipulated to display images on a phosphorescentscreen.[2] The images may represent electrical waveformson an oscilloscope, a frameof videoon an analogtelevision set(TV), digitalraster graphicson a computer monitor, or other phenomena like radartargets. A CRT in a TV is commonly ...
Fluoroscopy ( / flʊəˈrɒskəpi /) [1], informally referred to as " fluoro ", is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object. In its primary application of medical imaging, a fluoroscope ( / ˈflʊərəˌskoʊp /) [2] [3] allows a surgeon to see the internal structure and function of a patient, so that the pumping action of the heart ...
A gamma ray, also known as gamma radiation (symbol. γ. ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz ( 3 × 1019 Hz) and wavelengths less than 10 ...
Blu-ray ( Blu-ray Disc or BD) is a digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video ( HDTV 720p and 1080p ). The main application of Blu-ray is as a medium for video material such as feature films and for the physical ...
