World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Recovering Critical Elements From Wastewater for Battery Materials: A Review
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle
