... ), and paranatrolite, Na 2 Al 2 Si 3 O 10 ·3H 2 O ( Paukov et al. 2002 ) at T < 300 K. It is evident that the heat-capacity behavior for the H 2 O molecule in Mg-cordierite differs fundamentally from its behavior in the other micro/nanoporous phases. We interpret the macroscopic thermodynamic data in terms...

...Daniel R. Ferreira; Cristian P. Schulthess; James E. Amonette; Eric D. Walter Abstract The adsorption mechanisms of divalent cations in zeolite nanopore channels can vary as a function of their pore dimensions. The nanopore inner-sphere enhancement (NISE) theory predicts that ions may dehydrate...

... (run CaSr5) showed that it had a high porosity. The pore diameter was mostly 10 to 20 nm ( Fig. 4b ). Neither micro- nor nanopores were found in a thin foil cut from a strontium anorthite crystal from the starting material. Many pores contained a Sr-rich chloride phase. However, its Sr-Ca ratio could...

... measurements on disaggregated geologic materials may not represent chemical conditions in actual systems, because they may not be able to capture the effect of nanopore confinement. This possibility is consistent with the measurement of apparent distribution coefficients of radionuclides in saturated bentonite...
