Cold cathode ionization gauges are also available. Because they do not have active components such as hot filaments, cold cathode gauges can withstand sudden or prolonged exposure to high-pressure ...

Image credit: Handbook of Modern Sensors Ionization gauge Vacuum gauges which use ions are similar ... There are two types available: hot cathode and cold cathode. The main difference between the two ...

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.

Finally, cold cathode lights can be used for much more than illuminating the inside of your computer or making your whip look like it can hover. [James] discovered if he varied the voltage going ...

In this case, only four of the eight on the board are used to control red, white, blue, and green cold cathode tubes. The video after the break shows the device randomly rotating through different ...

Researchers have created a low-cost iron chloride cathode for lithium-ion batteries (LIBs). This innovation, developed by a ...

But, lithium-ion batteries aren’t perfect – this rise comes with risks, such as their tendency to slow down during cold weather and even catch on fire. The electrochemical energy storage ...

But the combination of an expansive cold front and an upcoming surge of cold, Canadian air, will change that and temperatures could drop to 10 to 15 degrees below average by midweek. As of ...

Cold Case: Who Killed JonBenét Ramsey traces the pageant princess’s murder along with how law enforcement and the media are alleged to have mishandled the case. Joe Berlinger, who worked on ...

Negative feedback control brings about changes that help return the body to normal conditions. If the body temperature drops, negative feedback control raises the temperature back to normal. If ...
