Maneuvering Charge Transport via Insulating Polymer Interface for Steering Photoredox Catalysis

Advanced Science, Volume 12, Issue 40, October 27, 2025.
Non‐conjugated insulating polymer functions as an electron‐capturing mediator to boost interfacial charge transfer and separation, contributing to considerably enhanced photocatalytic selective organic transformation and solar CO2 conversion under visible light irradiation. Abstract Maneuvering precise and tunable charge transportation has remained the

Preparation of Zwitterionic Silica‐Based Sorbents for Simultaneous Extraction of Acidic and Basic Pharmaceuticals From Water Samples

Journal of Separation Science, Volume 48, Issue 9, September 2025.
ABSTRACT The sol‐gel approach was applied to develop three homemade silica sorbents. These sorbents where functionalized with mixed‐mode zwitterionic exchange groups using only one additive to introduce at once the strong cation‐ (sulfonic groups) and strong anion‐exchange (quaternary amines) moieties. The developed materials were applied for the solid‐
