Electron crystallography — is a method to determine the arrangement of atoms in solids using a transmission electron microscope (TEM). Contents 1 Comparison with X ray crystallography 2 Radiation damage 3 Protein structures determined by electron crystallography … Wikipedia
Electron diffraction — is a technique used to study matter by firing electrons at a sample and observing the resulting interference pattern. This phenomenon occurs due to the wave particle duality, which states that a particle of matter (in this case the incident… … Wikipedia
Electron-positron annihilation — occurs when an electron and a positron (the electron s anti particle) collide. The result of the collision is the conversion of the electron and positron and the creation of gamma ray photons or, less often, other particles. The process must… … Wikipedia
Electron — E*lec tron, n. [NL., fr. Gr. h lektron. See {Electric}.] 1. Amber; also, the alloy of gold and silver, called {electrum}. [archaic] [1913 Webster] 2. (Physics & Chem.) one of the fundamental subatomic particles, having a negative charge and about … The Collaborative International Dictionary of English
Electron paramagnetic resonance — (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying chemical species that have one or more unpaired electrons, such as organic and inorganic free radicals or inorganic complexes possessing a transition metal ion. The… … Wikipedia
Electron density — is the measure of the probability of an electron being present at a specific location. In molecules, regions of electron density are usually found around the atom, and its bonds. In de localized or conjugated systems, such as phenol, benzene and… … Wikipedia
Electron beam physical vapor deposition — or EBPVD is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electron beam causes atoms from the target to transform into the gaseous… … Wikipedia
Electron spectroscopy — is an analytical technique to study the electronic structure and its dynamics in atoms and molecules. In general an excitation source such as x rays, electrons, or synchrotron radiation will eject an electron from an inner shell orbital of an… … Wikipedia
Electron beam machining — (EBM) is a machining process where high velocity electrons are directed toward a work piece, creating heat and vaporizing the material. Applications of this process are annealing, metal removal, and welding (see Electron Beam Welding). EBM can be … Wikipedia
