A perfluorinated carboxylic acid membrane, i.e. Flemion, shows improved performance as actuator material compared with Nafion (perfluorinated sulfonic acid). Flemion has a higher ion exchange capacity and good mechanical strength. In particular, Flemion will deform with no back relaxation under applied electrical stimulus. However, with water as solvent, the operation of Flemion in air has seri...

Recently, it has been found that room-temperature ionic liquids can be used as stable, unusual selectivity stationary phases. They show "dual nature" properties, in that they separate nonpolar compounds as if they are nonpolar stationary phases and separate polar compounds as if they are polar stationary phases. Extending ionic liquids to the realm of chiral separations can be done in two ways:...

Salts in the liquid phase at room temperature–ionic liquids– have recently received increased attention due to their unique properties.[1] These include high ionic conductivity, high thermal and chemical stability, broad electrochemical windows, non-volatility and non-flammability. These important properties make them versatile alternatives to conventional solvent-based systems, and their poten...

the density (d), speed of sound (u) and electrolytic conductivity (λ) for systems containing acetaminophen, ionic liquid {1-octyl-3-methyl imidazolium bromide, [omim] br} and water have been measured at t = 293.15-308.15 k. the measured data have been applied to calculate, standard partial molar volume ( ), hepler’s constant , apparent molar isentropic compressibility (kφ), transfer volume ( ),...
