We measured enthalpy of water adsorption and enthalpy of formation of lepidocrocite samples with surface area of 42–103 m 2/g. Having both quantities measured allowed us to calculate the surface enthalpy for a water-free surface of this phase as 0.62 ± 0.14 J/m 2 and the energy of a ...

In order to confirm the effect of "iceberg" formation of surrounding water on the enthalpy and entropy of solution of paraffin chain compounds, the effect of temperature on the critical micelle concentration (cmc) of C8F17SO3Li was determined up to 180°C at which it was still stable. The...

. This givesEaof 0.18 and 0.72 eV, respectively. TheEaandAparameters are compiled in Supplementary Table2. These parameters characterize the desorption–temperature profile. A steeper step gives a largerEatogether with a largerA. Such a correlation is reminiscent of the enthalpy–entropy ...
