Summary: Value-added formamides were synthesized sustainably by catalyzing in situ C-C bond cleavage with zeolite 5A supported Cu-based catalysts using glycerol derivatives as the carbonyl source. The introduction of Zr-IV ions greatly increased the activity of the Cu/5A catalyst. Isotopic tracing experiments confirmed the involvement of glycerol derivatives in the formation of formamide products.

Summary: The use of total volatile basic nitrogen (TVB-N) as a freshness marker for different meat types is still lacking understanding and consistent recommendations. The current research has not adequately addressed the mechanisms behind TVB-N generation and its association with meat freshness. Further studies and investigations are needed to establish more accurate and reliable freshness indicators for various meat types.

Summary: A novel one-pot, three-component reaction conducted under electrochemical conditions was studied. The reaction involved 2-aminothiophenols, aldehydes, and malononitrile, using TBABF4 as an electrolyte and CuI as a catalyst. The proposed reaction mechanism suggested that CuI served as an electron relay. This method offers simplified operation, high atom economy, and mild reaction conditions.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
