The influence of gas diffusion layer (GDL) microstructures on mass transport and methylcyclohexane saturation (MCH) in a dehydrogenation cell was investigated using pore network modeling. We reveal that GDLs with larger pore diameters (dpore) and lower tortuosity (τ) enable enhanced MCH invasion, thereby improving reactant concentration at the catalyst.

Apoptosis and the laws of thermodynamics
Nature Cell Biology, 2000The 'chemiosmotic hypothesis', formulated in the 1960s, revolutionized the study of the mitochondrion and made it accessible to thermodynamic analysis. The central aspect of the hypothesis is that the energy from electron transport is transduced into a proton electrochemical gradient (Δp) across the inner membrane, and that protons re-entering the ...

The zeroth law of thermodynamics
Physica A: Statistical Mechanics and its Applications, 1986We discuss a convenient formulation of the most intuitive property of equilibrium, the zeroth law of thermodynamics, in terms of conditions of dynamical stability for a system which may interact (weakly) with its surroundings. This allows us to provide a completely rigorous, though elementary, justification of the Gibbs canonical ensemble as the ...

In the previous chapter we began our study of the structure of matter by considering bulk matter in its most unstructured state, namely in its perfect gas state. We saw there that the general properties and gross behavior of this state of matter can be understood in terms of three measurable macroscopic quantities: the pressure, the temperature, and ...

The law of conservation (under transformation) of energy also goes under the somewhat old-fashioned and pompous name “the first law of thermodynamics”. The second and third laws will soon be revealed. For now we consider just the first.
