These days, it is impossible to think of an area of knowledge that can keep on
developing without a collaboration in interdisciplinary fields.
Electromotive force is a type of energy per unit of electric charge that is converted
reversibly from chemical, mechanical, or other forms of energy into electrical energy
by a dynamo, battery, electrochemical cells, thermoelectric devices, solar cells,
transformers, and so on.
The theory of electromotive Force is currently one of the most important research
topics within the electrical engineering domain.
NMR is an experiment in which the resonance
frequencies of nuclear magnetic systems are
NMR always employs some form of magnetic field
(usually a strong externally applied field B0)
NMR is a form of both absorption and emission
spectroscopy, in which resonant radiation is absorbed by
an ensemble of nuclei in a sample, a process causing
detectable emissions via a magnetically induced
Current Flow in an Electrochemical Cell:
Thermodynamic arguments permit the feasibility of overall cell reactions to be predicted, but give no information on rates. To understand the latter it is necessary to consider the effects on various parts of the cell of forcing the cell voltage to assume a value different from that of the equilibrium potential Eeq (V) or electromotive force (emf). In the example of Figure 1, the cell contains hydrochloric acid as aqueous electrolyte and it divides into two compartments by a semipermeable membrane.
