Dual‐Functional Carbon Dots as Electrolyte Additives for Enhancing Cathode Catalysis and Anode Stability in Li–O2 Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Li–O2 batteries garner widespread attention owing to their remarkable theoretical specific capacity. Nevertheless, the feasible implementation of the system is hindered by sluggish cathode reaction kinetics and poor anode stability. Herein, the carbon dots (CDs) with ‐OH, ‐NH2, and ‐COOH groups are synthesized and employed as electrolyte ...

Farm‐Scale Recharge Pits for Improving Local Groundwater Availability: Insights From a Hardrock Watershed in Rajasthan, India

open access: yesWorld 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
