Evidence of a phase transition in water-1-butyl-3-methylimidazolium tetrafluoroborate and water-1-butyl-2,3-dimethylimidazolium tetrafluoroborate mixtures at 298K: Determination of the surface thermal coefficient, [b.sub.T,P]
Article Abstract:
The surface thermal coefficient ([b.sub.T,P]) of mixtures between water and two imidazoliums salts, 1-butyl-3-methylimidazolium tetrafluoroborate(bmimBF4) and 1-butyl-2,3-dimethylimidazolium tetrafluoroborate (bdmimBF4), is determined in order to investigate this unusual behavior for cations with short alkyl chains. The discontinuity showed by the two salts is attributed to a transition such as an aggregation.

Monitoring growth of surfactant-free nanodroplets dispersed in water by single-droplet detection
Article Abstract:
A single-droplet detection method is employed for the investigation of the growth mechanism of surfactant-free-n-decane droplets dispersed in pure water. It reveals that Ostwald ripening and coalesce take place alternatively because the droplets loose their surface charge as the Ostwald ripening proceeds and then the droplets of coalesce.
