An ab initio Study of the Structure and Energetics of Hydrogen Bonding in Ionic Liquids

open access: yesFrontiers in Chemistry, 2019
Unlike typical hydrogen-bonded networks such as water, hydrogen bonded ionic liquids display some unusual characteristics due to the complex interplay of electrostatics, polarization, and dispersion forces in the bulk.

A family of ionic supersalts with covalent-like directionality and unconventional multiferroicity

open access: yesNature Communications, 2021
Binary ionic crystals, such as NaCl, are non-polar due to directionless ionic bonding interactions. Here, the authors show that polarity can be developed by using superalkali/superhalogen ions as building blocks, leading to ionic supersalts with ...
