Researchers at the Tokyo University of Science have shown that using copper can eliminate defects in sodium manganese oxide battery types, boosting battery cycle life.

Based on the field emission test results of the single wall carbon nanotubes (SWCNTs) cold cathode, a cold cathode electron gun for terahertz (THz) traveling wave tube (TWT) was studied. The ...

In recent years, transition-metal phosphides (TMPs) have drawn increasing attention as a battery-type cathode material for battery–supercapacitor hybrid (BSH) devices owing to their superior ...

By CST simulation, the X-ray tube based on gate controlled carbon nanotube cathode was designed. Preliminary researches were carried out on carbon nanotube cathode fabrication, metal mesh electrode ...

This was the discovery of the electron. J. J. Thomson devised many discharge tubes in his study of cathode rays. The one with the greatest import, both for his research and for experimental techniques ...

CUYAHOGA FALLS, Ohio (WKRC) - The body of a child was recovered and a man remains missing following an inner tube accident on a river in Ohio. The City of Cuyahoga Falls City Hall issued a ...
