Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Antibacterial Activity of Heteropolytungstates Against Proteus mirabilis

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
We investigated the in vitro antibacterial activity of several heteropolytungstates against P. mirabilis, a drug‐resistant pathogen. All tested polyanions inhibited bacterial growth, with the Preyssler–Pope–Jeannin polyanion P5W30 exhibiting the highest activity (MIC = 0.78 mg/mL).
