The electric field-jump method is applicable to reactions of ions and dipoles. Application of a powerful electric field to a solution will favor the production of ions from a neutral species, and it will orient dipoles with the direction of the applied field. The method has been used to study metal ion complex formation, the binding of ions to macromolecules, and acid-base reactions. 

There are few shortcuts. If you want a powerful electric motor, it is going to have to he large and entail an extensive amount of copper windings. That is why it is much more cost-effective to rebuild many large (more than 100 horsepower) industrial motors than to replace them with new motors. 

The popularity of EVs did not last. By the 1920s, the performance of ICE vehicles improved dramatically, and the earlier major drawbacks had been solved. Ironically, the replacement of the dangerous hand crank -with a battei y-powered electric starter was a major innovation accelerating ICE vehicle sales at the expense of EV sales. At the same time, there were no concurrent solutions to the limitations of battery technology for EVs that addressed the demand to drive faster and farther. 

Most urban rail service is electric-powered and most urban bus service is diesel-powered, although diesel rail and electric bus operations do exist, as noted above. The efficiency and environmental impacts of electricity depend gi eatly on the source of electric power. Although electric vehicles produce no tailpipe emissions, generation of electricity can produce significant emissions that can travel long distances, Eor example, coal-powered electricity plants produce particulate emissions that travel halfway across North America, Urban buses also can be powered by a variety of alternative fuels. 

There are forty to fifty water-powered electric plants reported to be online or under construction. 

Under some circumstances, e.g. the dissolution of a sparingly soluble solid, it may be more advantageous to make use of a mechanical shaker. Various models are available, ranging from wrist action shakers which will accommodate small-to-moderate size flasks, to those equipped with a comparatively powerful electric motor and capable of shaking the contents of large bottles vigorously. 

Particular examples of using polymer composites as screens are given in [14-16, 67-75], The present review does not touch the properties of the composite materials based on fabrics of conducting fibres due to the fact that manufacturing techniques for such materials are specific and differ greatly from the mixing processes considered above. However, these materials also have an application field, say, in contacts for calculator and computer keyboards [9] and even in small-power electric motor commutators as a partial substitute for copper [76, 77]. 

Magnet Fuse (pronounced Fuzee). A medium power electric detonator, invented in 1854 by Abel, which was fired electrically. The original fuze contd a priming mixt of Cu20, Cu2S and K chlorate packed around the exposed wire leads, and a main charge of either mealed pdr or MF. 

A sodium-sulfur cell is one of the more startling batteries (Fig. 12.23). It has liquid reactants (sodium and sulfur) and a solid electrolyte (a porous aluminum oxide ceramic) it must operate at a temperature of about 320°C and it is highly dangerous in case of breakage. Because sodium has a low density, these cells have a very high specific energy. Their most common application is to power electric... 

Our crystal-ball predictions are that DMFCs will first be commercialized as portable power sources for military and civilian applications before the year 2010 and that there will then be a quantum jump in the technology to be in a position to drive DMFC-powered electric vehicles 10 years thereafter.
