ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.WO3/SnSe micro‐nano composites demonstrate exceptional photocatalytic performance through synergistic strain and band modulation. Lattice strain modulation enhances methyl orange adsorption and visible light absorption, while Z‐scheme band alignment promotes efficient charge separation. The 2.5% WO3/SnSe composite achieves 99.71% degradation efficiency,

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...

Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration
European Journal of Organic Chemistry, EarlyView.The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Mechanistic and Reactivity Insights into Diboron‐Mediated NN and NN Bond Scission
European Journal of Organic Chemistry, EarlyView.This review highlights the emerging ability of diboron reagents to cleave both π‐bonded (N=N) and σ‐bonded (N—N) nitrogen–nitrogen linkages, integrating mechanistic understanding with recent synthetic applications. Diboron reagents have emerged as versatile reducing agents capable of transforming a broad range of functional groups through pathways like

Syntheses of some N-substituted hydrazines by the anhydrous chloramine process
, 1985 ClNH2, produced in the gas phase by the reaction of Cl2 and NH3, reacts with various primary and secondary amines in nonaq. solvents in the presence of a fixed base to form the corresponding N-substituted hydrazines.

Grassland Research, EarlyView.Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.
