Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings

Fish and Fisheries, EarlyView.
ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1677-1691, April 2026.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production
