Applying Karst Hydrology Concepts to Anthropogenic Subsurface Systems and Mine Water Management

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Due to the pronounced similarities between natural karst systems and mine workings, we consider mine workings as man‐made karst and present the concept of ‘anthropogenic karst’. ABSTRACT Mine water management is a permanent challenge in post‐mining areas where drainage adits play a crucial role for the regulation of water levels within partially ...

Advanced Characterization and Rejuvenation of End‐Of‐Life Lithium‐Ion Anodes: Toward the Development of a Green Upcycling Route

open access: yesSmall, Volume 22, Issue 14, 6 March 2026.
Green solvents (DI water or ascorbic acid) enable the regeneration of end‐of‐vehicle‐life battery anodes without delamination and re‐manufacture. Multimodal characterizations reveal several graphite microstructures and crystallography, and restored cycling performance.

Freshwater Conservation Priority Areas Are Threatened by Global Mining Activities

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Meeting global mineral demands, including those for decarbonization, risks amplifying threats to freshwater biodiversity. This study presents the first global mapping of conflicts between mining and freshwater conservation, revealing that mining may contaminate up to 1.8 million km of rivers, with over 18% within conservation priority areas.

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 1, Page 155-179, March 2026.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.
