We formulate an integral virial theorem which connects the change in the molecular electronic energy during finite changes in the size of the nuclear core (in the case of a diatomic molecule, during finite changes of the internuclear distance) with a matrix element of the kinetic electronic ...

In this review, we firstly focus on the fundamental electrochemical energy-storage mechanisms of TMCs, in terms of conversion- reaction process, pseudocapacitance-type charge storage, valence change for charge storage and catalytic conversion mechanisms. Based on the reaction mechanisms, various modi...
In the case of the physisorption process, the thermodynamic quantities like entropy change(ΔS), Gibbs-free energy change (ΔG) and heat of adsorption change (ΔH) have a negative sign. A negative enthalpy change represents the evolution of heat, which will again raise the system's temperatur...

where ΔL is the change in membrane length, and L is the original membrane length (12 × 10−4 m). Photoelectronic energy conversion photoelectronic energy conversion with the aramid membrane was investigated with and without illumination by recording the short ionic current and open circui...

The cart would not be able to roll because the gravitational potential energy changes with the cart's height, and this change in potential energy affects the kinetic energy of the system. If the cart was only allowed to have all kinetic energy or all potential energy, instead of rolling, ...
and heat storage systems that use both sensible and latent heat storage. The advent of phase change materials (PCM), such as thermally and chemically stable PCMs, for long-term storage, bio-degradable and bio-compatible PCM materials to alleviate the negative environmental impact of conventional PC...
A substance that lowers the activation energy of a chemical reaction is called acatalyst. Basically, a catalyst acts by modifying the transition state of a reaction. Catalysts are not consumed by the chemical reaction and they don't change the equilibrium constant of the reaction. Relationship Bet...
