Together We Are Stronger: An Unexpected Synergistic Effect During Anionic Ligand Exchange in Ruthenium Olefin Metathesis Catalysts

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Combining dichloro and diiodo ruthenium catalysts produces mixed chloro–iodo species via in situ halide exchange, resulting in a new, more efficient catalytic system. The mixed catalysts outperform their homo‐anionic counterparts, delivering enhanced activity, higher conversion, and strong suppression of isomerization under both thermal and ...

Synergistic Effects of Hydroxyapatite Supported Ni‐Pt Bimetallic Sites on the Efficient Reductive Regeneration of 1,4‐NADH

ChemCatChem, Volume 18, Issue 14, 29 July 2026.
This study demonstrates that nickel–platinum nanoparticles supported on biocompatible hydroxyapatite enable efficient reductive regeneration of nicotinamide adenine dinucleotide (NADH) using molecular hydrogen as a sustainable reductant. The bimetallic Ni–Pt system on nanocrystalline hydroxyapatite allows yields and selectivity in NAD+ reduction to be ...

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Co(II), Cu(II), and Ni(II) Coordination Complexes: Synthesis, Characterization, Experimental, and Computational Study on Potential Antiplasmodial Activity

ChemMedChem, Volume 21, Issue 12, 26 June 2026.
Four isostructural complexes (C1–C4) derived from 2‐(tert‐butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine with axial halides exhibit octahedral trans M(L)4X2 geometries, confirmed by X‐ray diffraction. They feature a discrete 1,6M7−1 topology, identified using ToposPro analysis.
