Dynamical aspects of the Na+ - Cl- ion pair association in water

The Journal of Physical Chemistry, 1992
Molecular dynamics is applied to analyze the association-dissociation process that takes place between contact and solvent-separated ion pairs for aqueous sodium chloride. A flexible single point charge model for water has been assumed. The reactive flux method has been used to compute the forward and backward rate constants.

Cracking Ion Pairs in the electrical double layer of ionic liquids [PDF]

, 2022
Here we investigate a limiting case of the theory for aggregation and gelation in the electrical double layer (EDL) of ionic liquids (ILs). The limiting case investigated only accounts for ion pairs, ignoring the possibility of larger clusters and a ...

Using Polar Ion-Pairs to Control Drug Delivery to the Airways of the Lungs

, 2020
The rapid absorptive clearance of drugs delivered to the airways of the lungs means that many inhaled medicines have a short duration of action. The aim of this study was to investigate whether forming polar ion-pairs can modify drug absorption to slow ...
