Innovations in water desalination: enhancing air gap membrane distillation performance by the incorporation of clay nanoparticles into PVDF matrix membranes
Adding clay nanoparticles into PVDF MMMs enhances MD performance. Higher OMT loadings improve contact angle, LEP, and flux. Long-term operation shows no flux reduction. Humic acid foulant reduces clay membrane flux by 45% vs. 60% for commercial PVDF.

Controlling saturation to improve per- and polyfluoroalkyl substance (PFAS) removal in biochar-amended stormwater bioretention systems
When stormwater biofilters are not saturated, per- and polyfluoroalkyl substances (PFASs) sorb to the air–water interface. The design of black carbon-amended stormwater biofilters for PFAS removal can be improved by preventing saturation.
