Studies of the electrical and mechanical responses of ferroelectric solids under shock compression show this technical problem to be the most complex of any investigated. The combination of rate-dependent mechanical and electrical processes along with strong electromechanical coupling has clouded physical interpretation of the numerous investigations. 

This is mixed with the acid of II., and the 2H2S04 restored, (iii.) The 2H20 may now be distilled from II. to I., and every- thing is in the same state as after the electrical process. The work done in the last process is ... 

The most prominent expression of cardiac activity is the rhythmical contraction of the heart - its pumping action. Less well known is the fact, that this mechanical activity is tightly controlled by an electrical process called excitation. ...

In the tensor formulation the difference between electric and magnetic fields disappears. What one observer interprets as an electric process another may regard as magnetic, although the actual particle motions that they predict will be identical12 [37].

The oxidation-reduction potential or redox potential ( h) is a measure of the tendency of a solution to be oxidizing or reducing. Oxidation and reduction are basically electrical processes that are readily measiued by an electrode potential. All measurements are referred to die standard hydrogen electrode, the potential of which is taken as 0.00 V at 298 K, the H2 pressure as 101325 N/m (1 atm) and activities of H2 and as unity. When the half-cell reaction is written as an oxidation reaction ... 

By 2015, research and develop high-and ultra-high-temperature thermochemical/electrical processes to convert hydrogen from high temperature heat sources (nuclear or solar) with a projected cost competitive with gasoline. 

A further intercellular communication mechanism relies on electrical processes. The conduction of electrical impulses by nerve cells is based on changes in the membrane potential. The nerve cell uses these changes to communicate with other cells at specialized nerve endings, the synapses (see chapter 16). It is central to this type of intercellular commimication that electrical signals can be transformed into chemical signals (and vice versa, see chapter 16). 

A thermo-electrical process for the production of carbon disulphide from its elements is also largely employed, especiallyinAmerica.4 The type of furnace generally employed is shown diagram-matically in fig. 15. The heat...

Electrometallurgy covers ihe various electrical processes for the Borlting metals. 

The use of electromagnetic techniques represents the final method for process intensification of heat transfer that will be dealt with here. Developments in the fuel cell sector hold out the promise of cheap electric power based on surplus hydrogen in chemical plants. The liberalization of the energy sector has also cut electricity prices and enhanced the attractiveness of using electricity in connection with chemical reactors. The precise regulation possible with electrical processes and their clean, environmentally friendly nature are further inducements for their application. 

There is not space here to explain the process of nerve impulse transmission. It is an electrical process and involves pumping of Na+ and K+ ions across barriers. It should be noted that there are cells other than neurons in the nervous system, of which the most abundant are glial cells. 

It is evident that the ability to direct and control energy and electron transfer processes in functionalized monolayers via optical and electrical processes is continuously evolving. However, greater complexity and extensive three-dimensional... 

Benjamin Franklin studied electricity in the mid-1700s. He developed the concept of positive and negative electrical charges. His most famous experiment showed that lightning is an electrical process.
