Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

Conclusion: Working Principle of Thermal Power Plants. In thermal power plants, the heat energy obtained from the combustion of solid fuel (mostly coal) is used to convert water into steam, this steam is at high pressure and temperature. The turbine shaft, which is connected to the generator, rotates the turbine blades using this steam.
