Partial Molar Entropy and Partial Molar Heat Capacity of Electrons in

... of electrons in the metal, n2 would be the number of lattice elements (e.g. lattice ions or volume elements, depending on the material or model), and S2 would be the partial molar entropy of lattice elements. Similarly, the entropy of an alloy is treatable as a multi-component system by extending th ...

... Gas diffusion across a proton exchange membrane (PEM) of a PEM fuel cell has important consequences for its performance and its durability [1,2]. Very thin membranes (~ 25 µm and less) are presently used in PEM fuel cells in order to decrease the membrane resistance and to increase power density. Ho ...

The ‘input’ felsic magma is modelled by a cold, low density fluid and the ‘resident’ mafic magma by a layer of fluid wax close to its solidi ...

Economizer

Economizers (US and Oxford spelling), or economisers (UK), are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, ventilating, and air conditioning (HVAC) uses are discussed in this article. In simple terms, an economizer is a heat exchanger.
