Islands of Space Suddenly there was a circle of blue light about the shadow form, and a moment later the ionized air relapsed into normal condition as the pirate's apparatus broke down under the strain. The Black Star Passes All by themselves, those sextuply ionized oxygen atoms would have a good bit to say, but they don't really begin to talk till they start roaring for those electrons I'm feeding them. The Ultimate Weapon Diffusion of the Ions.—The ionized gas acts like a mixture of gases, the ions corresponding to two different gases, the non-ionized gas to a third. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" A great flame of ionized air was the only result. Invaders from the Infinite It fell, a blazing wreck, but the ray touched a building behind it, and the ionized air established a conducting path between the ship and the planet. Islands of Space From the Solarite there darted a pale beam of ghostly light, faintly gray, tinged with red and green—the ionized air of the beam. The Black Star Passes Another method is plasma power, or power generated through the use of hot ionized gas. The Practical Values of Space Exploration Report of the Committee on Science and Astronautics, U.S. House of Representatives, Eighty-Sixth Congress, Second Session The rays on their way to the phosphorescent screen have to pass through gas which is ionized by the passage through it of the positive rays; this gas will therefore contain free corpuscles. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" Finally, as Thett's forces had planned, they came to one of the ionized layer ray-screen stations that was still projecting its cone of protective screening to the layer above. Invaders from the Infinite From the ship, a long pencil of rays, faintly violet from the air they ionized, reached out and touched the cliff. Islands of Space That it didn't explode when ionized, showed the absence of hydro-oxygen mixture. The Black Star Passes The drive unit would take water into itself, separate the ionized molecules, and expose them to an electric field. Tom Swift and the Electronic Hydrolung The air became acrid with the sharp odor of ionized air. The Revolt on Venus They have devised a new and very ionized layer as a conductor. Invaders from the Infinite Some of their elements had to be buried in plastic because otherwise they ionized the air and leaked current like a short. Operation Terror Thomson's interpretation—Ionized gas not obedient to Ohm's law—Discharge of charged conductors by ionized gas. The New Physics and Its Evolution Massless but energetic gamma rays can knock electrons out of neutral atoms in the same fashion as X-rays, leaving them ionized. Worldwide Effects of Nuclear War: Some Perspectives The physical reason for this is that the incredibly tenuous ionized gas which does the reflecting has a molasses-like viscosity. The Dawn of Amateur Radio in the U.K. and Greece: a personal view It is apparent that metallic salts of organic acids would, in aqueous solution, be ionized, the positive ion being the metal, and the negative ion the acid residue. The Project Gutenberg Encyclopedia Volume 1 of 28 Lockley knew that sharp points, when charged electrically, make tiny jets of ionized air which will deflect a candle flame. Operation Terror Evidences of a cyclonic tendency have been found, and Professor Hale has proved that sun-spots are strong magnetic fields, and consist of columns of ionized vapors rotating in opposite directions in the two hemispheres. Curiosities of the Sky The fact was, of course, that ionized air is more or less conductive. Operation Terror |
