A physicochemical investigation of ionic liquid mixtures.

Ionic liquids have earned the reputation of being 'designer solvents' due to the wide range of accessible properties and the degree of fine-tuning afforded by varying the constituent ions. Mixtures of ionic liquids offer the opportunity for further fine-tuning of properties. A broad selection of common ionic liquid cations and anions are employed to create a sample of binary and reciprocal binary ionic liquid mixtures, which are analysed and described in this paper.

False detection of atrial fibrillation in children by a blood pressure monitor with atrial fibrillation detection function.

A sphygmomanometer that can detect atrial fibrillation may help to identify asymptomatic patients who might benefit from anticoagulation. Its performance in young people has not been reported. In a school project measuring blood pressure in 60 normal healthy male teenagers (age range 13-18 years; mean±SD 15.
