Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, EarlyView.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, EarlyView.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.

Stability and Performance of Sn–Zn/C versus Sn–Cu/C Bimetallic Catalysts for Electrochemical Formic Acid Production Under Realistic Diluted Feed Conditions

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Beyond Pure CO2: Sn–Zn/C and Sn–Cu/C show comparable formic acid production under pure CO2 (40.81% vs. 29.17% FE), but only Sn–Zn/C maintains activity under realistic 50% CO2 dilution (42.7% retention) while Sn–Cu/C fails completely. Multimodal characterization reveals that thermodynamic oxide phase compatibility and textural stability are critical ...

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1769-1795, April 2026.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.
