Energy is treated in a number of articles. For the development of theconceptof energy and the principle of energy conservation,seeprinciples of physical science;mechanics;thermodynamics; andconservation of energy. For the major sources of energy and the mechanisms by which the transition of energy ...
In environmental science and economics, the phrase "free energy" is sometimes used to refer to renewable resources or any energy that does not require monetary payment. Free energy may also refer to the energy that powers a hypothetical perpetual motion machine. Such a device violates the laws o...
By definition, the change in potential energy when moving from one position to another is the negative of the work done by the conservative force acting during the change in position. Labeling U the potential energy and ΔU the change in potential energy, the definition may be expressed as (...
Unlike the definition in (18), these densities are not assumed to be equivalent. Variational inference proceeds by optimising the variational density such that it minimises free energy—often using the gradient flows in (17). However, there is a subtle difference between the dynamics of (17) ...
This Review highlights the definition, functions and potential of integrative catalytic pairs in multi-intermediate reactions, as a forward step relative to single- and dual-atom catalysts. Qilun Wang ,Yaqi Cheng &Bin Liu Article|16 February 2024 ...

This is uncharted territory and will impact on all branches of science! Ferrocell shows the connection between permanent magnetism and electromagnetism (light). –> Permanent+Electromagnetic=atom. The resulting field that can be observed is usually „dark“, unless illuminated using light. Its the...
The advantageous position of some countries regarding the availability of water resources enables the conduct of research analyses about the existing status of water resources of regional interest, as well as the definition framework of applied policies, measures, and actions for the management of ...

several important aspects of energy efficiency are addressed. After an introduction and definition of energy efficiency, historic development, state-of-the-art, and future trends of energy efficiency are presented in the light of life cycle assessment and total cost of ownership considerations. Energy...
