Detailed physics, predictive capabilities and macroscopic consequences for pore-network models of multiphase flow.
TL;DR: Pore-network models have been used to describe a wide range of properties from capillary pressure characteristics to interfacial area and mass transfer coefficients as mentioned in this paper, where the void space of a rock or soil is described as a network of pores connected by throats.

Towards sustainable fuels and chemicals through the electrochemical reduction of CO2: lessons from water electrolysis
TL;DR: In this paper, the main limiting phenomena affecting CO2 electrolysers and their causes are outlined, followed by the derivation, for several eCO2RR products, of targets in terms of durability, current efficiency, energy efficiency, faradaic efficiency, and overvoltage, which must be achieved for the e CO2RR to reach a similar energy storage capability as the electrochemical production of H2.

Scattering by an Inhomogeneous Solid. II. The Correlation Function and Its Application
TL;DR: In this paper, the angular intensity distribution of x-rays scattered by porous materials (hole structures) in the range of small angles is characterized by an exponential correlation function in the case of a distribution of holes of random shape and size in solid; a theoretical derivation of the exponential function is given for this case.
