The heat capacity of water near solid surfaces

Diffuse reflectance FT-IR spectroscopic study of interactions of α-Al2O3/molten alkali nitrate coexisting systems

“…It has been reported elsewhere [2][3][4][5] that the properties of water near the solid surface exhibit some anomalies, making them different from that of the bulk. This research has nowadays extended to the properties and structures of ionic species and/or solvents in the vicinity of solid systems.…”

Thermo-physical properties measurements of hygroscopic and reactive material (zeolite 13X) for open adsorptive heat storage operation

“…For example, at  = 50 °C, the specific heat of dry material is 910, 690, 1026, and 880 J kg -1 K -1 , respectively, for a range of 336 J kg -1 K -1 (relative uncertainty higher than 30%). Literature data for other materials (for example, zeolite 4A) is more consistent, but with the same variability and uncertainty [2,9,21,23,24,29].…”

“…Indeed, most classical techniques applied to the thermal properties investigation are based on a temperature difference in the material [20]. In the present case, a change in temperature modifies the water content (sorption equilibrium) and consequently generates heat [21][22][23]. As pointed out by Aristov [9], a computational approach does not allow to assess thermodynamic parameters with sufficient accuracy.…”
