The role of coexisting ions in a chemical oscillation induced by ionic surfactant molecules at a water/nitrobenzene interface
Article Abstract:
The mechanisms of the relaxation process in terms of coexisting ions in the oil phase are investigated. The mechanism for the nonlinear oscillatory behavior of the ionic surfactant molecules at the water/nitrobenzene (W/NB) interface is considered in terms of the remarkable difference in diffusion speed in the aqueous bulk phase and across the W/NB interface due to the contribution of water molecules that hydrate the surfactant molecules.

Proton NMR study on selective hydration of anions in nitrobenzene
Article Abstract:
A successful employment of (super 1)H NMR was done to study the selective hydration of ions in water-immiscible organic solvents. The intrinsic rotational correlation times evaluated for the hydrated anions in different states are larger than ~3 ps for free waters, suggesting the restriction of the rotational diffusion of water molecules by bonding with the anions.

Structure of nonpolarizable water/nitrobenzene interface: Potential distribution, ion adsorption, and interfacial tension
Article Abstract:
Adsorption of hydrophobic and hydrophilic ions at the nonpolarizable interface between two immiscible electrolyte solutions was investigated. The result revealed repulsion between adsorbed tetraalkylammonium ions at the nitrobenzene/water interface and demonstrated linear dependence between adsorption site and the size of a molecule.
