Melting and freezing behaviors of prototype ionic liquids, 1-butyl-3-methylimidazolium bromide and its chloride, studied by using a nano-Watt differential scanning
Article Abstract:
The melting and freezing behaviors of 1-butyl-3-methylimidazolium bromide ([bmim]Br) and its chloride ([bmim]Cl) are investigated by using a homemade differential calorimeter (DSC) with nano-Watt stability and sensitivity. The observed melting temperatures are due to the dynamics of the cooperative change between gauche-trans (GT) and trans-trans (TT) conformations of the butyl group in the [[bmim].sup.+] cation.

Mixing schemes in ionic liquid-H2O systems: A thermodynamic study
Article Abstract:
The hydration characteristics of room-temperature ionic liquids are studied. The excess chemical potential, mu(super E)(sub i), the excess partial molar enthalpies, H(super E)(sub i), and the excess partial molar entropies S(super E)(sub i) in ionic liquids-H2O systems at 25 degree Celsius are experimentally determined.

Thermodynamic properties of methane hydrate in quartz powder
Article Abstract:
A study of the thermodynamic (equilibrium) properties of methane hydrate in quartz sand at different temperature and pressure conditions is presented. The heat capacity of the hydrate is found to be the same as the heat capacity of ice.
