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.

Refers to people or corporate bodies who own or run manufacturing plants for making electronic equipment, devices, or components.

Movimiento de moléculas de un líquido a través de una membrana biológica semipermeable desde un campo menos concentrado a uno con mayor concentración de soluto bajo la influencia de un campo eléctrico.

Aplicar una capa protectora o decorativa de un metal sobre otro mediante baño electrolítico.

Producción de una superficie suave y brillante en un objeto metálico por la inmersión como un ánodo en un baño electrolítico.

Rama de la química concerniente con la relación entre electricidad y cambios químicos y con la interconversión de energía química y eléctrica.

Instrumento que detecta la carga eléctrica en un objeto, y que indica su magnitud en base a la atracción o repulsión magnética entre láminas o discos metálicos.

Technique developed by John Fenn in the late 1980s, an improved method of ionizing samples for use in mass spectrometry. Electrospray ionization (ESI) discharges a solution of a sample into an electric field that disperses the sample as fine droplets. ESI is especially useful for samples containing macromolecules, prone to fragmenting in other techniques of ionization.

A machine-assisted treatment method of removing dust and biological contaminants from paper, photographic materials, and textiles. Contaminant removal is performed by frictionless application of an electrostatic foil. The technology allows removal of dust contaminants from both sides, even from delicate surfaces, while keeping existing drawing and writing materials or pigment layers intact. In the cleaning and hygiene industry, the term is often used interchangeably with electrostatic disinfecting, which sprays a negatively-charged disinfecting solution onto a contaminated surface.

Placas metálicas de impresión realizadas mediante un molde de otra superficie de impresión, como un grabado en madera o tipo de conjunto, y galvanización de cobre.

Proceso de realizar placas de impresión utilizando un molde de otra superficie de impresión, tal como grabado en madera o tipos compuestos, y aplicando electroplaqueado con cobre.

Poemas tristes, melancólicos o quejumbrosos, especialmente cantos fúnebres o lamentos por los muertos.
