| electron optical system | <apparatus> A combination of parts capable of producing and controlling a beam of electrons to produce an image of an object. (05 Aug 1998) |
|---|---|
| electron optics | <study> The science that deals with propagation electrons, as light optics deals with that of light and its phenomena. Eye lens (see lens, eye). (05 Aug 1998) |
| electron paramagnetic resonance | <physics> A spectrometric method, based on measurement of electron spins and magnetic moments, for detecting and estimating free radicals in reactions and in biological systems. Synonym: electron paramagnetic resonance. (05 Mar 2000) |
| electron probe | <physics> A narrow beam of electrons used to scan or illuminate an object or screen. (05 Aug 1998) |
| electron probe microanalyser | <apparatus> The qualitative and quantitative use of X-rays excited by a microprobe of electrons. Available with scanning electron microscope and transmission electron microscope. Acronym: EMA (05 Aug 1998) |
| electron probe microanalysis | Identification and measurement of concentration of elements based on the fact that primary-emission X-rays emitted by an element excited by an electron beam have a wavelength characteristic of that element and an intensity related to its concentration. It may be performed by an electron probe microanalyzer, an electron microscope microanalyzer, or by an electron microscope, or scanning electron microscope, fitted with an X-ray spectrometer. (12 Dec 1998) |
| electron radiography | <radiology> Radiographic imaging in which X-radiation incident on the receptor is converted to a latent charge image and subsequently recovered by a special printing process; advantages include wider latitude of exposure and greater sensitivity than conventional film-screen combinations. See: xeroradiography, phosphor plate. (05 Mar 2000) |
| electron resonance absorption | <physics> A spectrometric method, based on measurement of electron spins and magnetic moments, for detecting and estimating free radicals in reactions and in biological systems. Synonym: electron paramagnetic resonance. (05 Mar 2000) |
| electron spin resonance | <physics> A spectrometric method, based on measurement of electron spins and magnetic moments, for detecting and estimating free radicals in reactions and in biological systems. Synonym: electron paramagnetic resonance. (05 Mar 2000) |
| electron spin resonance spectroscopy | <radiology> A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. electron nuclear double resonance (endor) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications. (12 Dec 1998) |
| electron trajectory | <physics> The path of an electron. (05 Aug 1998) |
| electron transfer flavin | <biochemistry> Flavoproteins that participate in the electron transport pathway. (05 Mar 2000) |
| electron-transferring flavoprotein dehydrogenase | <enzyme> System formed of electron-transferring flavoproteins plus EC 1.3.99.2 or EC 1.3.99.3 (butyryl-CoA dehydrogenase or acyl-CoA dehydrogenase) which reduces ubiquinone and other acceptors Registry number: EC 1.- Synonym: etf dehydrogenase, electron transfer flavoprotein-q oxidoreductases, electron transfer flavoprotein-ubiquinone oxidoreductase, etf-uo (26 Jun 1999) |
| electron velocity | <physics> The rate of motion of an electron. (05 Aug 1998) |
| electron-volt | <unit> A general unit of energy of moving particles, equal to the kinetic energy acquired by an electron losing one volt of potential, equal to 1.602 x 10-19 J. This is the energy an electron (or other particle of charge=1 such as a proton), gains as it is accelerated through a potential difference of 1 volt. In plasma physics the electron-volt is used as a unit of temperature when the mean particle energy is 1 eV, the temperature of the plasma is roughly 11, 600 Kelvin (the conversion from eV to K is via the Boltzmann constant). Abbreviation: eV (09 Oct 1997) |
