0 a chemical element that is a hard metal used in making light bulbs and strong types of steel: --
tungsten steel
The tungsten-tip cathode in the diode had diameter 4 mm and the stainless-steel anode had aperture 20 mm.
In this long-pulse mode, tungsten wire arrays radiated very effectively.
Dormancy may be induced by long days at least when tungsten bulbs are used for daylength extension.
Three different types of microelectrodes were utilized: varnish-insulated tungsten, glass pipette, or glass-coated platinum-iridium.
The resistance of tungsten wire at room temperature is two times higher than that of aluminum wire, and three times higher than that of copper.
Insulated tungsten electrodes were lowered through the dura into the thalamus.
This drive contained a tungsten-in-glass microelectrode which passed out of the guard tube and into the brain.
Large and fresh samples were split, jaw-crushed and reduced to powder in a tungsten carbide shatterbox.
