A Novel Connectivity Factor for Morphological Characterization of Membranes and Porous Media: A Simulation Study on Structures of Mono-Sized Spherical Particles

Abstract: In this study, we propose to define a connectivity factor as the inverse of the diffusional tortuosity to measure quantitatively the connectivity of whatever type of structure. The concept of connectivity used here is related to the diffusional accessibility of the structure voids. This definition of connectivity factor arises from the consideration that, if we ideally imagine to decrease progressively the porosity of a regular structure, the porosity itself reaches a limit value below which the inner pores ar… Show more

“…The structures of these two lattices are depicted in Figure 1 . In particular, the octahedral sites of the FCC lattice have the largest free volume, whereas the tetrahedral sites are the largest in the BCC lattice [ 10 ]. This means that the occupation of tetrahedral interstices by hydrogen in BCC lattices of the groups IV and V is favored over the octahedral ones, whereas the opposite behavior is found for hydrogen in palladium [ 11 ].…”

“…For example, the numerical domain regarded the nanopore as a long cylindrical structure to not only simplify the modeling but also reduce computational loads. However, the experiment counterpart was the periodic porous structure of FCC, so that the fluid flow and electrical characteristics were not constant along the SAPMs, although they were fixed values for the numerical calculations. , In fact, the real pore structures of the continuous 3D scaffold show higher complexity than those of our assumption …”

“…It must also be noted that the ceramic seems to negatively impact ion motion in the SIL as measured conductivities in the SCE are lower than those in LiG 4 TFSI (Figure ). Reduced conductivity is believed to be a result of increased tortuosity in the SCE relative to the SIL alone. − The TEM data (Figure ) shows that the SIL is present as a coating on the ceramic. This geometry is predicted to slow down lithium-ion motion through the electrolyte as ions now need to travel around and/or between these particles. , Nonideal morphology caused by the presence of ceramic particles has also been shown to result in decreased ionic conductivity in soggy sand-type electrolytes relative to that in liquid electrolytes .…”
