Abstract

Wetting In article number 2204012, Matthias Wessling and co-workers develop a microfluidic pillar-based model of a gas diffusion electrode and use it to track wetting phenomena in operando using fluorescence microscopy. Effects such as electrowetting and wetting of hierarchical pores are elucidated, enabling the direct study and mapping of reactions in porous electrodes.
