Hydroxide in ice – a new structure

In recent months I was working on the problem of proton mobility in water ice. Proton mobility involves hydroxide and hydronium ions. The first part of this study was focused on OH- ion (hydroxide) and its behavior in the bulk of ice. We found a new structure which OH- prefers in ice and which is a trap for OH-. This “off-the-lattice” configuration, as we called it, immobilizes hydroxide and hinders the overall proton mobility. The article describing our results was accepted as a communication in PhysChemChemPhys and was selected as a “Hot Paper”. Moreover, it made a cover picture in the last issue of PCCP which makes me especially glad (the second cover picture of mine).
