Ionic liquids (ILs) do not have a detectable vapour pressure at room temperature. But scientists at the University of Nottingham have managed to measure the enthalpy of vaporisation of a series of imidazolium-based ILs with the help of mass spectrometry.

The authors found that the ILs evaporated as neutral ion pairs.

The self assembly of proteins into fibrils has been implicated in conditions including Alzheimer’s disease.

Scientists in Australia have shown that the amyloid fibrilization of the peptide Aβ16-22 – an important fragment used to model full length Aβ – is promoted in protic ionic liquids (pILs) containing phosphate or sulphate ions and suppressed in pILs contain mesylate ions.
