Critical mineral removal from mining‐impacted waters using microalgal biomass

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

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.
