Orthogonal One‐Pot Dual Catalysis Enabled by a Hybrid Chiral Diene/Phosphine Ligand

Advanced Synthesis &Catalysis, Volume 368, Issue 14, 17 July 2026.
A hybrid chiral diene–phosphine ligand enables orthogonal one‐pot Rh/Pd relay catalysis, delivering high yields and enantioselectivities while outperforming dual‐ligand systems. A hybrid chiral diene‐phosphine ligand (L1) enables orthogonal one‐pot relay catalysis by integrating distinct metal‐coordination sites within a single molecular framework. The

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

Solvent‐, Catalyst‐, and Heating‐Free Mechanochemical Depolymerization of Polyurethane

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
A sustainable mechanochemical strategy is developed for polyurethane depolymerization under ambient conditions using only NaOH. Ball milling enables efficient urethane bond cleavage, allowing up to 69% polyol recovery from commercial PU foams within 3 h. This energy‐efficient approach offers a novel route for polyurethane recycling.

Degradation Pathways of Carbonate‐Based Electrolyte Formulations in Potassium Vanadium Phosphate/Graphite Potassium‐Ion Batteries

Batteries &Supercaps, Volume 9, Issue 7, July 2026.
Herein, a K3V2(PO4)3/graphite potassium‐ion battery is presented as a reference system to study electrolyte formulations and their degradation pathways using a complementary analytical approach to study both soluble degradation products and surface deposits at the electrode–electrolyte interface.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1683-1707, July/August 2026.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1821-1834, July/August 2026.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1835-1860, July/August 2026.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...
