Book Description
Excerpt from An Experimental Determination of the Temperature of the Mercury Arc: Thesis The problem.of efficient light production is to produce the most light with the least consequent development of heat. The way for the solution of this problem is Opened in the carrying of electricity through gases, for theoretically there is.no limit to the efficiency of a luminescent vapor. The gas is the most efficient the lower its temperatur %)and the heat produced is merely a by - product. This is just the reverse of a solid incandescent body, for, while heat makes a solid incan descent it increases the pressure of a gas but does not make it incandescent. The heat put into a gas does not reappear, to any extent, in an increased vibration of the molecules but it causes them.to move faster in their rectilinear paths and they, in turn, cause an increase in pressure by striking the boundary at a higher velocity. Although vibrations in a gas are not produced by heat they may be produced by making the gas the conductor of an electric current. In which case the vibrations are at a definite rate and give line spectra. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
The purpose of the 1989 NATO ARW was to develop applications, and an improved understanding of the physics for high current emission and conduction observed in hollow cathode-hollow anode switches including the pseudo spark and BLT. New applications include highly emissive cathodes for microwave devices, accelerators and free electron lasers, high power tubes, electron and ion beams, microlithography, accelerators, and other plasma devices. Recent research has produced a new generation of gas-phase plasma switches that are characterized by very high current emission and conduction while operating in a glow mode. These switches include the pseudospark and the BLT, both of which have hollow electrodes, switch over 10 to 100 kA peak current, and have cathodes with emission ~ 2 2 10,000 Ncm over ~ 1 cm area. The cathode properties are especially remarkable - about 2 orders of magnitude larger emission than existing thermionic cathodes. Part of the meeting was devoted to understanding these properties, and exploiting applications of this cathode. The remarkable properties of these switches are very surprising in the light of considerable previous work in this area, and these results deserve study in order to understand the underlying physical mechanisms, and to develop ideas and insight into future applications, and foster coherent research in this area. The operating cycle of pseudo-spark and BL T switches and related devices can be divided into four phases: hold-off, triggering, conduction, and recovery. There was very little discussion of the hold-off and recovery phases.

Book Description
Embraced by the inside covers' periodic table of elements and table of solutions of acids, the new edition of this introductory text continues to describe laboratory operations in its first part, and experiments in the second. Revisions by Ault (Cornell U.) include detailed instructions for the disposal of waste, and experiments with more interesting compounds (e.g. seven reactions of vanillin, and isolating ibuprofin from ibuprofin tablets). Conscious of costs, microscale experiments are included but not to the point where minuscule amounts of material will preclude the aesthetic pleasure of watching crystals form or distillates collect.
