This study investigates azurite (and malachite) pigments from important European deposits with special focus on their trace elemental composition. Using advanced analytical techniques, researchers discovered that specific trace elements, such as rare earth elements or uranium, can be key indicators of pigment provenance. These findings were applied to historical artworks, revealing that the overall trace […]

The study investigates the correlation between calculated and measured 77Se NMR chemical shifts in various selenaborane cluster compounds, showing that low-level quantum chemical calculations can reliably predict these shifts. This predictive ability helps in understanding the molecular structure of selenaboranes and efficiently locating 77Se resonances in experimental data. The findings highlight how accurate prediction of […]

Activated borane (ActB) is a metal- and halogen-free porous borane cluster polymer that effectively serves as a heterogeneous catalyst for hydrodehalogenation of aliphatic fluorides and chlorides, using triethylsilane as a reductant. It demonstrates high thermal stability, reusability, and significant Lewis acidity, making it capable of achieving full dehalogenation with high turnover numbers, even after multiple […]
