Imaging the dynamical hydration sphere of alkali metal ions

Written by

Professor Hayamizu and colleagues study the dynamic behaviour of alkali metal ions in aqueous solutions.

Alkali metal ions – lithium ion (Li+), sodium ion (Na+), potassium ion (K+), rubidium ion (Rb+), and caesium ion (Cs+) – play crucial roles in a variety of solution processes, but so far tracking their diffusive motion in water has been problematic. Professor Kikuko Hayamizu and her collaborators at Tsukuba University, Japan, have applied a technique based on nuclear magnetic […]

Facilitated ion transfer through liquid-liquid interfaces

Written by

The transport of ions across the interface between two immiscible liquids, like water and oil, is a central process in a variety of phenomena.

The migration of charged ions through interfaces between immiscible liquids plays an important role in several natural and technological processes. Prof Akihiro Morita of Tohoku University in Japan uses molecular dynamics simulations to develop models of the complex phenomena involved in the motion of ions across interfaces under the effect of external electric fields. This powerful approach is providing detailed […]
