Choline saccharinate and choline acesulfamate are two examples of hydrophilic ionic liquids, which can be prepared from easily available starting materials (choline chloride and a non-nutritive sweetener). The (eco)toxicity of these ionic liquids in aqueous solution is very low in comparison to other types of ionic liquids. A general method for the synthesis and purification of hydrophilic ioni...
Quasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible state-counting scheme, involving different assumptions on statistical correlations. Thermal activation of quasiparticle pairs and thermodynamic properties of the fractional quantum Hall liquids ne...
The design and fabrication of textured surfaces has received much attention during the past decade. In case of a hydrophobic texture a modified surface profile can lead to a very large contact angle, which induces exceptional wetting properties. A remarkable mobility of liquids on such SH surfaces is observed in the Cassie state, where the textures are filled with gas, which renders them “self-...
Mixtures of ionic liquids with organic solvents exhibit a most interesting research area in thermodynamics. The increasing utilization of ionic liquids in chemical processes and separation processes requires reliable and systematic data of thermodynamic and thermophysical properties such as activity coefficients, VLE and LLE data, heats of mixing as well as gas solubility data, densities and tr...
The natural gas market is currently undergoing dramatic changes and is becoming globalized. One of the major developments in the global natural gas market in recent years is the establishment of the Gas Exporting Countries Forum (GECF). Since the founding of this forum, there have been many speculations about whether GECF would become a cartel like OPEC. Cartels contributes to the coordination ...
Catalysts immobilised in ionic liquids have been analysed using electrospray ionisation ion trap mass spectrometry, which allows identification of the catalyst without contamination from the ionic liquid; additionally, a new ionic liquid containing the Monsanto catalyst as the anionic component, [Rh(CO)2I2]-, has been characterised using the same method.
