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

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.

Endogenous Versus Exogenous Redox‐Mediators in Anaerobic Bioelectrochemical Systems: A Comparative Study With Pseudomonas putida

ChemElectroChem
The choice of redox mediator is a critical design factor in microbial bioelectrochemical systems. However, selecting between externally added (exogenous) or metabolically synthesized (endogenous) mediators remains challenging, and a direct in vivo ...

Beyond Technological Maturity: Understanding the Institutional Trajectories of Carbon‐Derived Renewable Methane in the European Energy System

EcoEnergy, EarlyView.
We demonstrate that the limitation of bioCO2‐derived methane is systemic rather than technological, and provide a validated framework for traceability, certification, and policy alignment enabling its integration into RFNBO‐compliant value chains and EU energy systems. ABSTRACT Renewable methane derived from biogenic CO2 (bioCO2) occupies a paradoxical

Putting System Co‐Design at the Center of Chemo‐Biohybrid CO2 Valorization From Lab to Industrial Scale

EcoEnergy, EarlyView.
Chemo‐biohybrid systems promise much, but single‐discipline research still limits progress. This perspective draws on thermocatalytic, electrocatalytic, and photocatalytic hybrid systems to highlight the need for system‐level co‐design and outline future directions.
