Surface heterogeneity in micropores of pillared clays: the limits of classical pore-filling mechanisms
Article Abstract:
The microporosity of Al13-intercalated and -pillared synthetic saponites with variable layer charge was investigated by high-resolution quasi-equilibrium adsorption volumetry and low-temperature adsorption microcalorimetry. Results indicated a strong correlation between adsorbed quantities of nitrogen and argon, and the amount of intercalated aluminum. This indicates that a simple micropore-filling procedure cannot interpret N2 and Ar adsorption on intercalated and pillared clays.

Hydration of synthetic clay with tetrahedral charges: A multidisciplinary experimental and numerical study
Article Abstract:
The use of well-defined synthetic clay sample enables to understand in details water absorption by combining energetic, structural, and molecular information. By working on synthetic samples with octahedral substitution in which cation/layer interactions should be very different from that of tetrahedrally charged samples such as saponites, the description of clay/water systems can be completed.

Hydrophobic hydration in an orientational lattice model
Article Abstract:
The microscopic mechanism of hydrophobic hydration is analyzed by studying a simplified lattice model for water solutions in which the orientational nature of hydrogen bonding as well as the degeneracy related to proton distribution are taken into account. The results have suggested the presence of ordering of water particles in the first hydration shell.
