Most rechargeable batteries that power portable devices, such as toys, handheld vacuums and e-bikes, use lithium-ion ...

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.

New technology has allowed scientists to create ultra short ion pulses, with a duration of less than 500 picoseconds. This can be used to analyze materials or even make chemical reactions visible in ...

In scanning electron microscopy, a thermionic electron source such as a tungsten filament is usually used. The subject of this tutorial, the Hitachi S-4700 FE-SEM, utilizes a cold cathode field ...

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 ...

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 within ...

With global demand for lithium-ion batteries fast depleting reserves of raw materials ... AZIBs usually use zinc metal as an anode and inorganic or organic compounds as a cathode. While substantial ...

We’ll start with the CRT TV – also known as the tube TV, because CRT stands for cathode-ray tube. This is what started it all, and we were all pretty happy with it for, oh, a little over 65 years.

Evoking the past and reflecting the present, architecture and design play a significant part in shaping our perception of a place. Travelers may even be inspired to visit a destination based on ...
