Thermodynamic properties of compressed solid hydrogen

Accurate thermodynamic properties of gas phase hydrogen bonded complexes.

We have measured the infrared spectra of ethanol·dimethylamine and methanol·dimethylamine complexes in the 299-374 K temperature range, and have determined the enthalpy of complex formation (ΔH) to be -31.1 ± 2 and -29.5 ± 2 kJ mol(-1), respectively. The corresponding values of the Gibbs free energy (ΔG) are determined from the experimental integrated absorbance and a calculated oscillator stre...

Two-Temperature Thermodynamic and Transport Properties of Hydrogen Plasmas

The knowledge of two-temperature transport coefficients is of interest in the modelling of fluid flow and heat transfer processes in electric propulsion devices. Variations of species mole fraction, number density, specific enthalpy, specific heat at constant pressure, viscosity, electrical conductivity and thermal conductivity as a function of pressure, electron temperature and different degre...

Cation distributions and thermodynamic properties of binary spinel solid solutions

A general model is presented to enable the calculation of the cation distribution and thermodynamic properties of any binary solid solution between oxide spinels containing 2*, 3* and 4* cations. The model includes the effect ofdisordering enthalpy which depends linearly on the degree of disorder. In addition there are important contributions to the thermodynamic properties from the size mismat...

Improved organic hydrogen carriers with superior thermodynamic properties.

By the incorporation of N atoms into naphthalene, we present a theoretical investigation to seek for improved organic hydrogen carriers with an explicit guideline, the release of H2 is found to be greatly favored thermodynamically and the corresponding cycloalkanes possess high hydrogen storage capacity, this offers extensive candidates for practical applications of the promising hydrogen energy.
