Kinetics of electrochemical dissolution of metals in porous media
A model is proposed to predict the corrosion rate of steels embedded in different porous media including concrete, wood and soil. It relies on the moisture state and the pore structure, which affect the electrochemical dissolution kinetics.

Decoupling the role of stress and corrosion in the intergranular cracking of noble-metal alloys
The model alloy of Au–Ag is studied to decouple the role of stress and corrosion in intergranular cracking caused by metal dissolution. Nanoporous corrosion layers can mechanically inject a crack into grain boundaries of the parent phase.

Sharpened interface
The finding of a sharp interface between a chemically attacked surface and the pristine bulk in a borosilicate glass is at odds with the widely held diffusion-based mechanisms of glass durability.

Spontaneous evolution of bicontinuous nanostructures in dealloyed Li-based systems
For alloys displaying diffusive transport behaviour, understanding the electrochemical factors that control dealloying-induced morphologies could prove important for battery development. Composition, particle size and dealloying rate are now shown to affect morphology evolution in the Li–Sn system, and dealloying is found to be governed by both percolation-dissolution and solid-state-diffusion mechanisms.
