Selective Oxidation of Primary Amines to Nitriles Catalyzed by the Ru‐Doped Hexagonal Perovskite SrMnO3

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
The selective oxidation of primary amines to generate nitriles provides a cost‐effective and atom‐economical synthetic approach that avoids the formation of harmful byproducts. However, achieving high yields under mild conditions remains challenging, due to the difficulty in efficiently activating the α‐CH bonds of amines and the multiple competing ...

Strong Lateral Confinement of Hydrophilic Silica Nanoparticles on Mg‐Al Layered Double Hydroxides Nanoflakes for Enhanced Thermal Properties

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
A nanostructured, naturally flame‐retardant, and non‐toxic inorganic composite is introduced, which is laterally associated with silica nanoparticles to induce the restacking of the LDH lamella structure, thereby serving as an efficient thermal insulator.
