Solvothermal Fabrication of Trimetallic Oxides NCs: Exploring Their Magnetic and Photocatalytic Characteristics

Nano Select, Volume 7, Issue 4, April 2026.
A trimetallic NiFe2O4/ZnO/Co3O4 nanocomposite is synthesized via a solvothermal route and thermally tuned by post‐annealing. Structural, optical, and magnetic properties evolve systematically with temperature, enabling efficient sunlight‐driven degradation of mixed organic dyes.

Synthesis of Polysubstituted Tetrahydro‐1,4‐Thiazepines by Rhodium‐Catalyzed Ring Expansion of Dihydro‐1,3‐Thiazines with Diazoesters

Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.
A rhodium(II)‐catalyzed ring expansion of stereodefined dihydro‐1,3‐thiazines with diazomalonates gives 1,4‐thiazepines via a sulfonium ylide rearrangement. The reaction shows a cis/trans reactivity divergence arising from different metal coordination, as revealed by experiments and density functional theory studies.
