Pore-filling impregnation method

WebBy changing the pore size and the chemistry of the surface, we propose to learn about the pore filling processes from adsorption experiments at high temperature; we relate them to the T-behavior within the pore of a thermodynamic quantity, the averaged density, and the mobility, via the measurements of the mean square displacements over a large T-range … Webpore to the outer surface. Indeed, it has become increasingly evident that most porous materials possess complex networks of pores of different size and shape (Levitz 2002). It might be thought that the dimensions of the pore entrances or constrictions within the network could be assessed from the desorption branch of the loop (de Boer 1958).
