In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Is there a role for cannabidiol in obesity, metabolic syndrome and binge eating?

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) is one of the most abundant phytocannabinoids isolated from the Cannabis sativa plant. CBD is a lipophilic, non‐intoxicating substance that differently from Δ9‐tetrahydrocannabinol (Δ9‐THC) does not present the typical profile of a drug of abuse.
