Equilibrium models of pore formation have no adequate physical analogues, and their study should be considered just as the first approximation in the exploration of nonequilibrium systems. Historically, just the equilibrium approach (Cerofolini) became the first attempt of description of microporous material formation. [Pg.41]

Many theoretical and experimental studies carried out in the past deal with the study of the solid motion inside a rotary cylinder, drum or kiln [1-8]. Saeman s model, developed in 1951, is undoubtedly the first attempt for modelling such motion [1] this mechanistic model is widely [Pg.315]

The theoretical and experimental investigations of rupture and permeability of amphiphile bilayers are valuable also for the understanding of some microstructural effects in interfacial layers and phases of small volumes. The interpenetration of macroscopically measured quantities, e.g. r and W, by means of molecular statistical models seems to be most interesting and useful. As first attempts in this respect, a molecular statistical lattice model of such bilayers has been proposed [427] and a lattice model of such bilayers has been studied by means of Monte Carlo simulation by Chowdhury and Stauffer [429]. The results obtained have been compared with some experimental data presented in this Section. Clearly, the combination of macro and micro considerations is a promising way to obtain a deeper insight into the properties of matter and, especially, of interfacial layers and phases of small volumes.
