“A cathode emits a stream of electrons that collides with neutral atoms of xenon, a gaseous element, in a chamber.”

“Current can only flow from the anode to the cathode, but not the other direction.”

“That is more rarefied than the near vacuum in a television cathode ray tube.”

“The test rig must be capable of routing to catholyte solution to either the second electrochemical cell or the column.”

“Gaseous hydrogen and oxygen flow separately around either side of two electrolytic plates serving as anodes and cathodes.”

“It produces copper concentrates by means of floating sulphurated mineral, and copper cathodes using a lixiviation process of oxidised mineral.”

“Also at Cathodeon he was working on hot cathodes in lamps used in analytical instrumentation.”
