Electrode
An electrode is a small piece of metal or other substance that is used to take an electric current to or from a source of power, a piece of equipment, or a living body. Any terminal that conducts an electric current into or away from various conducting substances in a circuit, as the anode or cathode in a battery or the carbons in an arc lamp, or that emits, collects, or controls the flow of electrons in an electron tube, as the cathode, plate, or grid. (Or) An electrode is a solid electric conductor that carries electric current into non-metallic solids, or liquids, or gases, or plasmas, or vacuums. Electrodes are typically good electric conductors, but they need not be metals. In an electrochemical cell, reduction and oxidation reactions take place at the electrodes. The electrode at which reduction takes places is called the cathode. Oxidation takes place at the anode. The electrodes are useful in analytical chemistry, in batteries, and in electrolysis.
The following types of electrodes are as follows active electrode, calomel electrode, carbon dioxide electrode, Clark electrode, coated wire electrode, depolarizing electrode, dispersive electrode, gas-sensing electrode, glass electrode, hydrogen electrode, immobilized enzyme electrode, indifferent electrode, internal reference electrode, ion-selective electrode, liquid membrane electrode, multiple point electrode, negative electrode, oxygen electrode, PO2 electrode, point electrode, polarographic electrode, polymer membrane electrode, positive electrode, reference electrode, saturated calomel electrode, Severinghaus electrode, solid-state membrane electrode, standard hydrogen electrode, subcutaneous electrode, surface electrode, and therapeutic electrode.
Edelweiss publications maintaining the journal of Nanomaterial chemistry and technology which accepts all the original manuscripts related to electrode.
