• the proton solvation is usually limited by the Zundel cation and the Eigen cation. The difference between potential energy of these cations is very small (ca. 2–3 kcal/mol); as a result, these two solvation forms can interconvert on the femto- to picosecond time scale [97]. While the proton transport

• mechanism is believed to involve the inter-conversion between these cations [97], the details of the solvation process and aqueous proton transfer are still unknown for ionomer membranes. In order to identify water–proton complexes H+(H2O)n with n = 1–4, the hydronium oxygens were first selected as those

• ][21][22][23][24][25][26]. While there have been numerous attempts to develop models to take traps in unipolar devices into account [27][28][29][30][31], nearly all of them still rely on drift as the only transport mechanism. However, traps will often lead to a situation where diffusion currents cannot

As most of these lizards are unable to lick water from most parts of their body, such a water transport mechanism is essential for them.

The transport mechanism is homogeneous and the animal's mouth serves as a water sink. Thus when the capillary
