Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Protein–Anthocyanin Interactions in Food Systems: A Reaction‐Network Perspective on Equilibria, Kinetics, and Degradation Pathways

open access: yesChemFoodChem, EarlyView.
Protein–anthocyanin interactions are reinterpreted beyond binding affinity through a reaction‐network perspective. Distinct protein classes modulate anthocyanin behavior through equilibrium shifts, matrix‐driven protection, self‐assembly, or covalent conjugation.

Sacrificial anode Fered–Fenton process for the degradation of a model naphthenic acid in high‐salinity water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Fered–Fenton treatment of saline produced water: generation of reactive oxygen species and enhanced degradation of cyclohexane carboxylic acid through in‐situ electrochemical Fenton reactions. Abstract Offshore oilfield produced water (OPW) is a highly complex and hypersaline effluent from oil and gas extraction industry.

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and
