Chemistry – A European Journal, EarlyView.The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Mercury (Hg) Isotope Biogeochemistry
Journal of Environmental Chemistry, 2009 Mercury (Hg) is a globally distributed and highly toxic pollutant in the environment. Its mobility and biomagnification in aquatic food chains depend on its biogeochemistry and redox cycling. Hg isotope analysis is an important new tool for identifying Hg source and tracking Hg transformations in the environment.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Geological Journal, EarlyView.Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Journal of the Chinese Chemical Society, EarlyView.A trinuclear manganese complex supported by the 7‐Dipy scaffold undergoes controlled multielectron oxidation from Mn(II)3 to high‐valent Mn(IV)3 states. Spectroscopic signatures, including 16‐line and geff ≈ 5 EPR features, reveal stepwise redox accumulation. The oxidized Mn3 cluster mediates efficient oxygen‐atom transfer to strong CH bonds, enabling
