Ab initio molecular dynamics simulations of salty water under an electric field reveal two regimes of the relative mobilities of chlorine and sodium ions. When water dissociation and proton transfer are actived at strong field intensities, the presence of the ions hinders the efficiency of the proton transfer mechanism.

The high temperature phases of the solid acids CsHSeO4, CsHSO4 and CsH2PO4 show extraordinary high proton conductivities, which are enabled by the interplay of high proton transfer rates and frequent anion reorientation.

By means of ab initio simulations we unveil the high reactivity of boron nitride–graphene planar heterostructure immersed in liquid water: an interfacial water molecule is found to spontaneously chemisorb and deprotonate at one composite border.
