Capillary condensation of nitrogen in MCM-48 and SBA-16
Article Abstract:
The temperature dependence of the adsorption-desorption isotherm of nitrogen was measured onto MCM-48 and SBA-16 materials, respectively, with well-defined three-dimensional networks of cylindrical pores and cagelike pores, over a wide temperature range of 0.43 to 0.90. The results for MCM-48 strongly suggest that interconnections among pores of almost the same size and geometry do not have significant effect on the adsorption hysteresis and pore criticality.

Ionic liquids of chelated orthoborates as model ionic glassformers
Article Abstract:
Ionic liquids based on various chelated orthoborate anions of different N-containing onium cations were synthesized using an economic synthesis strategy. The hydrophobic properties and their high fragilities of these liquids may provide model systems for fundamental liquid investigations.

Mode-coupling SRLS versus mode-decoupled model-free N-H bond dynamics: mode-mixing and renormalization
Article Abstract:
The original and extended model-free (MF) formulas are perturbational expansions of slowly relaxing local structure (SRLS) models. A detailed analysis of eigenmodes and spectral densities is given.
