Differentiating between F and OH Ligands in Homologous Gold(III) Complexes beyond X‐Ray Crystallography

European Journal of Inorganic Chemistry, Volume 28, Issue 34, December 1, 2025.
A subtle hydrogen‐bonding lock enables the unequivocal structural differentiation between fluoride and hydroxide in the unusual couple of homologous organogold(III) complexes [PPh4][(CF3)3AuF] and [PPh4][(CF3)3Au(OH)] (see adjacent figure). The homologous fluoride and hydroxide complexes of gold(III) [PPh4][(CF3)3AuX] [X = F (1), OH (2)] have been ...

Selective Vapor‐Phase Formic Acid Decomposition Over Carbon‐Supported Rhenium Catalysts with Metallic, Carbide, and Oxide Rhenium Phases

ChemistryOpen, Volume 14, Issue 12, December 2025.
Carbon‐supported rhenium catalysts with metallic, carbide, and oxide phases were evaluated for vapor‐phase formic acid decomposition. Rhenium carbide exhibited the highest intrinsic activity and superior CO2 selectivity, while graphite provided enhanced dispersion compared to carbon nanotubes, highlighting phase‐dependent performance in hydrogen ...

Fault‐Induced Hydration and Serpentinization of the Incoming Lithosphere Enhances Intra‐Slab Seismicity Offshore Taltal (∼25°S), Northern Chile

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The northern Chilean margin is one of the most seismically active subduction zones, with a high potential for future megathrust earthquakes. The tectonic structure and the state of hydration of the incoming Nazca Plate, and their control on seismogenesis are poorly known, as the offshore domain remains largely unexplored. Here, we present high‐

Aperiodic Clustered and Periodic Hexagonal Vegetation Spot Arrays Explained by Inhomogeneous Environments and Climate Trends in Arid Ecosystems

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Due to climate change, overgrazing, and deforestation, arid ecosystems are vulnerable to desertification and land degradation. As aridity increases, vegetation cover loses spatial homogeneity and self‐organizes into heterogeneous vegetation patterns, a step before a catastrophic shift to bare soil.
