Graphene Oxide Membranes for Recovery of Catalytically Depolymerized Lignin Monomers and Oligomers

ChemSusChem, Volume 19, Issue 20, 28 October 2026.
Poplar lignin is oxidatively depolymerized to produce water‐soluble liquor containing monomeric acids and low‐molecular‐weight (LMW) oligomers. When the depolymerization product liquor fractionated through an ultrathin reduced‐graphene‐oxide laminate, the 2‐D nano‐channels transmitted the valuable ≤1.6 kDa species into the permeate, while high‐MW ...

Removal of adsorbing estrogenic micropollutants by nanofiltration membranes:Part B-Model development [PDF]

, 2013
Removal of estrone (E1) and estradiol (E2) by nanofiltration membranes at neutral pH is carried out both by size exclusion and adsorption. Size exclusion is dependent on the solute to pore radius ratio and the hormone-membrane affinity. It has been shown

Hierarchical Membrane for Photoelectrostatically Gated Monovalent‐Divalent Ion Separation

Angewandte Chemie International Edition, Volume 65, Issue 44, 26 October 2026.
We report a hierarchical poly(ionic liquid)–carbon nitride membrane supported on anodic alumina for efficient monovalent/divalent ion separation. Confined nanochannels and tailored interfacial ion interactions enable exceptional K+/Mg2+ ( > 500) and Li+/Mg2+ ( > 200) selectivities, offering a promising strategy for advanced aqueous ion separations ...
