An atom or molecule with a net electric charge due to the loss or gain of one or more electrons
Forming nouns denoting the action of a verb or an instance of this
A device in which ions are produced (typically by the ionization of a gas) and emitted in a beam.
A current of ions moving in a fixed direction.
The damaging of the phosphor of a cathode ray tube by negatively ionized gas molecules produced by the electron beam and focused on to the screen; an ion spot so produced.
= ion engine.
= ionization gauge.
Such a pair held together in a solution by electrostatic attraction.
A device for removing gas molecules from a space by ionizing them and applying a potential difference.
A small area struck by a beam of ions.
A cometary tail composed of ionized gases, typically forming a straight bluish tail pointing directly away from the sun; (more generally) a narrow stream of ions following the orbital trajectory of a planet or other body.
A device designed to catch or trap ions; specifically one in a cathode ray tube or television camera tube that prevents ionized molecules from reaching the screen or the target and causing an ion spot.
To bombard with ions; to direct an ion beam at; usually in pass.
= ionization chamber.
A specialized pore in a cell membrane or other biological membrane which controls the passage of a specific inorganic ion (as calcium or potassium).
A rocket engine that employs ion propulsion.
The controlled removal of extremely thin layers of material from the surface of an object by the use of an ion beam.
= ion engine.
A source of ions; especially a device for producing ions, such as an ion gun.
A free radical species that carries a charge.
Subjected to ion bombardment.
Subjected to or altered by ion exchange.
Designating a system or apparatus which interacts with a specific ion or type of ion according to its particular physical properties, specifically designating an electrode which generates an electric potential by such interaction (as used in measuring ionic concentrations).
The movement or transfer of ions; specifically the active or passive exchange of inorganic ions across a cell membrane or other biological membrane.
An organic cation in which the positive charge is located on a carbon atom
Another term for hydroxonium ion.
The exchange of ions of the same charge between an insoluble solid and a solution in contact with it, used in water-softening and other purification and separation processes
A solid used in ion exchange, typically a special cross-linked synthetic resin or a zeolite
A machine or apparatus for accelerating ions; specifically a particle accelerator that does this.
The fact of being struck by a beam of ions; specifically the process of bombarding a surface with ions (usually ions of an inert gas) as a means of removing impurities.
That brings about ion exchange; capable of ion exchange.
The process of propelling or accelerating ions; specifically a mode of rocket propulsion in which thrust is generated by the ejection of ions produced inside the engine and accelerated by an electric field.
The ion H3O+, consisting of a protonated water molecule and present in all aqueous acids
= ion-exchange chromatography.
The implantation of ions in a crystalline material, as in the doping of a semiconductor.
A synthetic polymer suitable for use in ion exchange.
An electron microscope that works on the same principle as the field emission microscope but using ions produced at the surface of the emitter or in a surrounding gas, rather than electrons.
= ion-exchange resin.
A technique for separating and analysing ions or polar molecules in a solution by passing it through a column whose contents have charged surfaces which attract, and so slow, the ions to an extent which varies with their size and charge.
