Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Iron‐Catalyzed Hydrodecarboxylation of Fatty Acids From Vegetable Oils for Drop‐In Biofuel Production

European Journal of Organic Chemistry, EarlyView.
An iron‐catalyzed hydrodecarboxylation for renewable hydrocarbon production is reported, featuring an alternative hydrogen source and a commercially available iron salt as the catalyst. The protocol enabled efficient one‐pot Cn–1 hydrocarbon synthesis from vegetable oils under mild and open‐air conditions.

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

Food Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

Metabolite Profiles and Antioxidant Activity of Dendrobium catenatum Under Simulated Wild Cultivation

Food Safety and Health, EarlyView.
Dendrobium catenatum grown under simulated wild cultivation showed significantly higher flavonoids and stilbenes, leading to enhanced antioxidant activity in both leaves and stems compared to facility‐grown plants. Integrated metabolomics, antioxidant assays, and network pharmacology identified Denbinobin as a key multi‐target antioxidant compound ...
