A cold cathode is a cathode in a gas-filled electron tube that is not heated by a filament. The voltage potential within the tube is sufficient to ionize the gas and cause the current to flow.

A research team from the Skoltech Energy Center, led by Distinguished Professor and director of the center Artem Abakumov, ...

Currently, the Cybertruck is equipped with a 123-kilowatt-hour battery pack with nickel-cobalt-manganese cells. Last year, it ...

The cathode tube was a prime example. By switching on some voltage, scientists could make fluorescent streams of electricity travel from the bottom part of a glass tube to the top -- but no one ...
