Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Nonequilibrium Laser Regulation of the Electronic Structure of the Ni‐Based Electrode for Boosting Nucleophilic Electrooxidation of Alcohols

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
This work reports an efficient, simple, low‐cost, and scalable method for overall electrode preparation. Nonequilibrium laser synthesis rapidly yields NiO nanocrystals on which a nickel oxyhydroxide (NiOOH) overlayer is grown in situ. By varying the number of laser pulses, the Ni3+/Ni2+ ratio is precisely tuned, thereby modulating the electronic ...
