A new study finds windy conditions can weaken St. Elmo's fire, the phenomenon when electrically conductive structures spontaneously emit a flash of blue light, when it's generated by aircraft and ...

WHEN an electric glow discharge is passed through a tube containing air at pressures of the order of 5 cm. of mercury, the tube lying in one of the two beams in a Jamin's refractometric arrangement, ...

In this article, we discuss the principle behind the functioning of glow discharge optical emission spectrometry, some of its practical applications as well as studies that have used the technology in ...

For the spectrochemical study of solid materials with a glow discharge, the Grimm lamp is the geometry of choice. In the late 1960s the initial design was created when Werner Grimm of RSV ...

For the first time in history, scientists from Pennsylvania State University have recorded the electric glow of trees during a thunderstorm in natural conditions — a phenomenon that researchers have ...

For the first time, scientists have filmed high-speed video of a phenomenon where trees emit an electrical glow by generating sparks during thunderstorms. The results of a study published in ...
