Negative Pressure Regimes in Ionic Liquids: Structure and Interactions in Stretched Liquids as Probed by NMR

In this work, a broad pallete of macroscopically sized samples of ionic liquids was used, in which tensions of about -100 MPa were obtained in preliminary testing methodologies before cavitation would occur. Preliminary NMR studies have been performed on ionic liquids under homogeneous tension. Upon...

Summary:In this work, a broad pallete of macroscopically sized samples of ionic liquids was used, in which tensions of about -100 MPa were obtained in preliminary testing methodologies before cavitation would occur. Preliminary NMR studies have been performed on ionic liquids under homogeneous tension. Upon entering into these metastable regimes of negative pressure, it is possible to observe a sharp increase in the anion and cation self-diffusion coefficients as compared to the equilibrium saturated liquid conditions at identical temperatures.
