Pore structure - Wikipedia
Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.
A soil’s porosity and pore size distribution characterize its pore space, that portion of the soil’s volume that is not occupied by or iso-lated by solid material.
Pore size measurement techniques - Anton Paar
A wide range of pore sizes from 0.35 nm to over 100 nm can be analyzed with high accuracy using vacuum-volumetric or gravimetric adsorption techniques. Samples regularly evaluated using gas adsorption include zeolites, clays, activated carbons, templated materials, metal-organic frameworks, pharmaceuticals, catalysts, and many more.
Characterization and Analysis of Porosity and Pore Structures
Most of the total porosity measurements are variations on bulk volume/grain volume or bulk density/grain density approaches, and the apparent porosity measurements were made by variations of absorption methods for different fluids or gases.
Large Pores: Identification, Causes, Treatments and Prevention
