Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

Enhancing the Performance of Aqueous Lithium‐Ion Batteries via N‐Methylpyrrolidone Additive

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aqueous lithium‐ion batteries (ALIBs) have garnered significant attention in the field of energy storage due to their inherent safety. However, their practical application is severely constrained by a narrow electrochemical window and electrolyte crystallization at low temperatures.

Advancing Environmental Sustainability: The Role of Artificial Intelligence in Monitoring, Predicting, and Controlling Sulfur Dioxide Emissions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Air pollution from sulfur dioxide (SO2) emissions poses significant threats to environmental sustainability, public health, and climate change efforts. Despite advances in monitoring and regulatory frameworks, traditional methods often fall short in accuracy, scalability, and efficiency.

Barrier Properties and Crystalline Structure of Biowax‐Containing Water‐Based Polymer Dispersions Under Different Processing Conditions

Journal of Applied Polymer Science, EarlyView.
This study investigates the nanoscale structures of biowax materials using the wide‐angle x‐ray scattering method. The biowaxes are combined with water‐based polymer dispersions to create barrier coatings for fiber‐based food packaging materials.

Diol Chain‐Length Effects in Adipate and Succinate Polyesters for Thermoplastic Polyurethanes

Journal of Applied Polymer Science, EarlyView.
This study examines 20 aliphatic polyesters as soft segments for thermoplastic polyurethanes (TPU), synthesized from adipic or succinic acid and diols (C2, C3, C4, C5, and C6). A pronounced odd‐even effect shows that even diols crystallize, while odd diols remain amorphous.

Mechanical Properties and Thermo‐Oxidative Aging of Hybrid EPDM Formulations With Bio‐Based Oils

Journal of Applied Polymer Science, EarlyView.
This study evaluates bio‐based oil as an eco‐friendly replacement for paraffinic oil in EPDM rubber. While pure bio‐oil matches conventional mechanical properties, specific blends (25% and 75%) improve tensile strength and stiffness. The 50% blend requires tempering to optimize its sulfur network and morphology, eventually yielding a 35% strength ...
