Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

Deep Underground Science and Engineering, EarlyView.
This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

Harnessing Natural Wood Architecture: A Self‐Supporting, Hierarchically Porous NiFe@Carbon Capacitive Anode Enhances Electricity Generation and Storage in Microbial Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study reports a mild “Zn(NO3)2 interlayer‐expansion” strategy combined with electrodeposition to produce a self‐supporting capacitive anode (NiFe@PC) that preserves the wood's native low‐tortuosity channels. The retained native architecture expands niches for microbial colonization.
