2. Sample discussion

The first purpose of this discussion will therefore be thermodynamic, to illustrate the aforementioned problem and get to the heart of the matter. As shown in figure 2 , we can schematize a meso-microporous grain with a de facto micro-mesoporous volume. This porous volume is subject to a pressure known as the Laplace pressure. If we place this porous grain in a surrounding liquid, the liquid will initially enter the periphery of the grain by capillary action and/or osmotic pressure, but very quickly we'll reach a thermodynamic equilibrium (in this case, mechanical equilibrium) where osmotic/capillary pressure...
