TL;DR: In this work the liquid/vapour and the solid/liquid interfaces of a series of ionic liquids and the polarity fractions of standard liquids considered as "polar" liquids are investigated and may be considered as moderately polar.

TL;DR: In this paper, the surface tension and viscosity of two imidazolium-based ionic liquids, 1-ethanol-3-methylimidazolate tetrafluoroborate [C2OHMIM][BF4] and 1-methyl-3 -octylimide-naphroxymethylamidazole (OMIM)-tetrafluoric acid [BF4], were investigated.

TL;DR: In this paper, the application of membrane processes to filter the thin spent sulphite liquor (SSL) produced by Eucalyptus globulus sulphite pulping, namely for the separation of the lignosulphonates (LS) from the sugars, LS fractionation to produce valuable products, and sugars concentration, was investigated.

TL;DR: In this article, the authors investigated electrowetting of several room temperature ionic liquids having in common the cation or the anion on poly(tetrafluoroethylene) (PTFE) and found the typical behavior of aqueous salt solutions: symmetric parabolic curves of contact angle versus (positive and negative) applied voltage, at low voltages, and contact angle saturation after a threshold voltage.

TL;DR: In this paper, the relative positions of the alkyl chains on the methylpyridinium cation were found to have an important effect on the tribological performance of these ionic liquids.
