Because energy is defined in terms of work, the SI unit of energy is the joule (J), which was named after James Prescott Joule and his investigations on the mechanical equivalent of heat. In more basic terms, 1 joule equals 1-newton meter and, in terms of SI base units. \[1J = 1kg...

Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or various other forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Lea
Free energy, in thermodynamics, energylike property or state function of a system in thermodynamic equilibrium. Free energy has the dimensions of energy, and its value is determined by the state of the system and not by its history. Free energy is used t
In the current work, ZSM-5 zeolite showing a dendritic 3D nanoarchitecture has been synthesized by the functionalization of protozeolitic nanounits with an amphiphilic organosilane, which provokes the branched aggregative growth of zeolite embryos. Dendritic ZSM-5 exhibits outstanding accessibility arising...
‘Smart energy systems are defined as an approach in which smart electricity, thermal, and gas are combined and coordinated to identify synergies between them in order to achieve an optimal solution for each individual sector as well as for the overall energy system’. ...
Condensation turbines are most frequently applied in electrical power generation. The condenser's pressure is 0.02 bar, and the temperature of the exchanged steam is only about 30°C. The arrangement may be single casing, tandem compound, or cross-compound turbines. Single casing units are the ...
The main results of the model can be structured in these topics: Investment: (generation, storage, hydro reservoirs, electric lines, hydrogen pipelines, and heat pipes) investment decisions and cost Operation: unit commitment, startup, and shutdown of non-renewable units, unit output and aggregati...
Filtering capacitor with compact configuration and a wide range of operating voltage has been attracting increasing attention for the smooth conversion of the electric signal in modern circuits. Lossless integra-tion of capacitor units can be regarded as one of the efficient ways to achieve a ...
Ionization energy, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule. The ionization energy associated with removal of the first (most loosely held) electron, however, is most commonly used.
