Nature of Acid‐Base Site of Co‐Precipitated Zinc Silicates

open access: yesChemCatChem, Volume 18, Issue 21, 12 November 2026.
Preparation of zinc silicate by co‐precipitation at control pH give materials with tunable Zn/Si and their acid‐base properties are strongly linked to this ratio. The reactivity of MBOH along the base route increases with the synthesis pH, thus with the Zn/Si. The silanol groups and the Lewis acidity of the Zn(II) are strongly modified by the synthesis

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5954-5978, November 2026.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Box–Behnken optimization and ANN‐ANFIS integrated modelling for transesterification using thermally activated basic oxygen furnace slag catalyst

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5991-6006, November 2026.
Abstract Global energy demand and environmental concerns have intensified the search for renewable and sustainable energy sources. This study thus, focuses on optimizing the transesterification process of waste cooking oil (WCO) using thermally activated basic oxygen furnace slag catalyst calcined at 850°C (BOF 850). The optimization and modelling were

Redox‐Active Verdazyl Radical Polymers via Postpolymerization Modification of Active Ester Polymers

open access: yesChemPlusChem, Volume 91, Issue 11, November 2026.
Organic radical polymers were synthesized via postpolymerization modification (PPM) of poly(pentafluorophenyl (meth)acrylate) with diverse 6‐oxoverdazyl stable radicals. This work servs as an electrochemical proof‐of‐concept, exhibiting a chemically reversible redox couple at 3.43 V versus Li/Li+, validating the electrochemical accessibility of the ...
