Selective Electrochemical sp3 CO Bond Hydrogenolysis: From Model Compounds to Lignin

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Electrochemical sp3 CO bond cleavage is systematically investigated under constant‐current conditions using simple aryl ether models and extended to organosolv lignin. Controlled electron flow, regulated proton availability, and a sacrificial magnesium anode enable selective lignin depolymerization, yielding chemically distinct fractions with aromatic

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Sulfur‐Stabilized High Entropy Oxysulfides Enable Efficient CC Bond Cleavage in Ethylene Glycol Electrooxidation for Sustainable Plastic Upcycling to Formate

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Room‐temperature synthesis method of high‐entropy oxy‐sulfide (HEOS) is introduced. Compared to high‐entropy oxides (HEO), sulfur incorporation promotes oxygen vacancy stabilization and facilitates CC bond cleavage, improving efficiency of ethylene glycol electrooxidation to formic acid. Lower cell overall voltage enables sustainable plastic upcycling

Polyurethane Cascade Depolymerization by a Combination of Thermal Pretreatment and Enzymatic Hydrolysis

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
This study explored the cascade depolymerization of a polyether‐polyester polyurethane based on a combination of low‐temperature thermal treatment and enzymatic hydrolysis. Heat pretreatment changed the physicochemical properties of polyurethane, followed by cutinase‐catalyzed hydrolysis, leading to an increase in weight loss and the production of two ...

Influence of Hornification Treatment and Fiber Length on the Performance of Recycled Polypropylene Composites

Polymer Composites, Volume 47, Issue 5, Page 4793-4803, 10 March 2026.
Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,
