The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate

open access: yesChemPhysChem, Volume 27, Issue 4, 25 February 2026.
Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.

Fractionation of AquaSolv Omni Biorefinery Lignins and Their Application in Antioxidant and Ultraviolet‐Protective Films

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Sequential fractionation of AquaSolv Omni biorefinery lignins allowed to obtaining of lignin/lignin–carbohydrate complexes with potent antioxidant and Ultraviolet‐shielding properties, showing adaptable glass transition behavior that can be tailored according to the selected application requirements. Lignin and lignin–carbohydrate complexes (LCCs) were
