Accordingly, reversible processes ought to be regarded as approximations, rather than idealizations. Here, we critically assess his proposal. In doing so, we offer a resolution of his alleged paradox based on the original work by Tatiana Ehrenfest-Afanassjeva on the foundations of thermodynamics....
In thermodynamics, a phase is defined as a spatial region with relatively uniform and stable structure, and a field is a function of space and time. Literally, the phase-field model is a computational model which describes microstructure evolution of material systems as a function of space and ...
Due to volatile sugar prices, the food vs fuel debate, and recent increases in the supply of natural gas, methanol has emerged as a promising feedstock for the bio-based economy. However, attempts to engineer Escherichia coli to metabolize methanol have
Devices and phenomena relying on hydrogen transport or incorporation: (a) protonic ceramic reversible cells for energy applications; the upper set of arrows correspond to the upper circuit showing electrolysis and hydrogen production, whereas the lower set correspond to fuel-cell operation for power gen...
The model is developed within the classical framework of thermodynamics of irreversible processes. Volume fractions of self-accommodated and oriented martensite are selected as scalar internal variables, while the preferred direction of oriented martensitic variants is assumed as a directional internal ...
Thermodynamics model Mass and energy balance The initial design of a power plant begins with the selection of the corresponding thermodynamic cycle, construction of a power plant model, and determination of the technical specifications for each component of the equipment through simulation. Every device...
Thermodynamics Modelling and simulation hydrogen–bromine redox flow battery Open circuit potential Bromine electrode Activity coefficient 1. Introduction An economically viable redox flow battery (RFB) system is characterised by low cost of energy storage, which can be achieved by increasing the battery ...
Tags Energy Internal Internal energy Isobaric Isochoric Thermodynamics In summary, the change in internal energy for an ideal gas remains the same in an isochoric process and an isobaric process, as long as the change in temperature is the same. This is because internal energy in an ideal...
thermodynamics and kinetics of these two pathways in AM+-free and AM+-containing aqueous solutions. The interfacial cation concentration used is approximately 2.3M, which would correspond to a bulk concentration of roughly 0.1M–0.5M, as predicted by simulations of cation accumulation at the ...
Green hydrogen produced by water splitting using renewable electricity is essential to achieve net-zero carbon emissions. Present water electrolysis technologies are uncompetitive with low-cost grey hydrogen produced from fossil fuels, limiting their sca
