A nonmetallic element of the halogen family with atomic number 53 and symbol I. It is a dark crystalline solid used as an additive to salt to prevent iodine insufficiency and is used in dyes, photographic film, x-ray contrast media, and other applications.

Cualquier átomo o grupo de átomos que poseen una o más cargas eléctricas positivas o negativas.

Refers to analysis of materials on a microscopic or macroscopic scale using a beam of positively charged light ions. Ion beam analysis (IBA) techniques are often used to study works of art, because of their noninvasive and nondestructive character. These techniques exploit the products of interactions between beams of accelerated charged particles and the target in order to determine its elemental composition.

Reciprocal and reversible transfer of ions of the same charge between a solution and a relatively insoluble solid in contact with it. Cation exchange and anion exchange are, respectively, the exhange of positively and negatively charged ions. Ion exchange is used in such applications as kidney dialysis, water purification, and chemical analysis.

A surface analysis technique which measures the elastically scattered ion created when a primary ion beam is directed at the sample surface. The kinetic energy of the reflected primary ion depends on the mass of the surface atom involved in scattering, thus revealing information about the sample surface.

Active, passive, or facilitated movement of salts and other electrolytes in the form of ions across energy-transducing cell membranes.

Any of the range of synthetically polymerized organic compounds suitable for use in ion exchange.

An electrode which has a high degree of selectivity for one ion over others present in a sample.

Nationality, culture, and style of one of the four major divisions of the ancient Greek people, along with the Aeolians, Achaeans and Doric. the Ionians were an ancient Hellenic people inhabiting Attica, parts of western Asia Minor, and the Aegean Islands in pre-classical times.

Proceso por el cual los electrones son perdidos desde o transferidos a moléculas o átomos neutros para formar partículas cargadas positiva o negativamente.

Polymer composed of macromolecules in which a small but significant proportion of the constitutional units has ionic or inonizable groups, or both.

Artefactos de radar pulsados para medir la altitud vertical de los estratos de la ionósfera.

Culture or condition of citizenship or residency of the U.S. state of Iowa.
