Creación de imágenes alterando las propiedades eléctricas del material sensible como resultado de la acción de la luz.

Galvanizado mediante un proceso en el cual el cinc es depositado por un método de electrochapado.

Término genérico para la clase de técnicas electrostáticas de copiado.

Paso de una corriente eléctrica a través de un electrolito con la consiguiente migración de los iones cargados positiva y negativamente a los electrodos negativo y positivo. En conservación, úsese para la limpieza de depósitos superficiales.

Sustancia que conduce corriente eléctrica como resultado de la descarga de iones positivos y negativos a terminales (cátodo y ánodo) de un circuito eléctrico, específicamente el fluido conductor usado en una batería.

The quantitative relationship between a varying magnetic field and the electric field created by the change. This potential difference, or electromotive force, by motion of a conductor in a magnetic field is the fundamental operating principle of electrical transformers, inductors, and electrical motors. It was first observed by Michael Faraday ca. 1831, and is described by Faraday’s law of induction.

El fenómeno asociado con los campos eléctricos y magnéticos y su interacción entre ellos, con cargas y corrientes eléctricas.

Instrumentos calibrados para medir voltajes muy bajos sin necesidad de contar con una corriente significativa.

Partículas elementales cargadas negativamente que constituyen el todo de un átomo, ocupando una órbita atómica alrededor del núcleo. Fueron descubiertas por J. J. Thomson in 1897.

Application of electron diffraction in the backscattering mode as used in analysis of crystallographic structure of textured materials that show a preferred orientation of crystalline components. Electron backscatter diffraction (EBSD) is based on the measurement of the diffraction pattern formed by the electrons backscattered toward a phosphor screen positioned at an angle from the sample surface. The visible lines generated by the impinging electrons are called Kikuchi bands; thus the technique is also known as backscatter Kikuchi diffraction (BKD).

Elastic scattering of beam electrons from a sample in a direction approximately opposite to that of the incident radiation. Backscattered electron (BSE) imaging is a technique used in examination of archaeological artifacts to make surfaces of materials visible.

Treatment of objects under elevated temperature and nitrogen atmosphere by high energy electrons for various purposes including cross-linking of polymers and sterilization.

Electron energy loss spectroscopy measures the energy of scattered electrons reemitted from surfaces after bombardment by an electron beam, thus determining the distribution of energy loss. Provides data complementary to Auger electron spectroscopy which operates according to the same principle but uses a different process to produce the electrons.

A radiographic technique that uses secondary electrons emitted from a thin lead foil (100 to 250 micrometers) to produce an image of the examined object on a radiographic film.

Of a device, instrument, information storage, or other applications, operating according to the principles or methods of electronics, such as having a transistor, microchip, or electron tube. For appliances or instruments that are powered by electricity, use "electric."

Refers to an optical technique which enables interferometric measurements of surface displacements. When laser light is scattered by a rough surface it generates a random intensity distribution known as a speckle pattern.The technique allows visualization and measurement of the three dimensional distribution of displacement and strain/stress on the object.

La rama de la física que abarca el estudio del comportamiento y control de electrones que influyen a través de semiconductores, el vacío o gases y el diseño y aplicación de artefactos y sistemas cuya operación depende completa o parcialmente de las características y comportamiento de los electrones.
