MXene‐Enhanced Electromembrane Systems for Advanced Water Applications: A Review

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
MXenes, synthesized via etching, intercalation, and delamination, exhibit hydrophilicity, conductivity, tunability, and strength, enabling roles as membranes, electrodes, and hybrids in electrical‐driven membrane technologies. These systems leverage adsorption, catalysis, separation, and self‐cleaning but face challenges in stability, scalability ...

Natural Source Zone Depletion of Crude Oil in the Subsurface: Processes Controlling Mass Losses of Individual Compounds

open access: yesWater Resources Research, Volume 62, Issue 1, January 2026.
Abstract At many petroleum hydrocarbon spill sites, residual spilled product forms a long‐term source of groundwater contamination. The phrase source zone natural depletion is used to refer to the mass loss rates. Overall mass lost under environmental conditions was analyzed using conservative biomarker concentrations for a 1979 oil spill in northern ...
