Site-specific substitution in atomically precise carboranethiol-protected nanoclusters and concomitant changes in electronic properties
This study presents the synthesis and structural modification of a silver-based nanocluster [Ag17(o1-CBT)12]3- (Ag17) by incorporating Au and Cu at specific sites, forming AuAg16, Ag13Cu4, and AuAg12Cu4. These modifications systematically alter their structural, electronic, and optical properties, with Au stabilizing the core and Cu enhancing photoluminescence and prolonging excited-state lifetimes. The study demonstrates a tunable […]
Expanding Luminescence Horizons in Macropolyhedral Heteroboranes
The macropolyhedral compound anti-B18H22 was long thought to be the only boron hydride compound that exhibited fluorescence when illuminated with ultraviolet light. We have recently shown that new and, indeed, some previously known macropolyhedral compounds, containing sulphur or selenium, and exhibiting a wide range of structural types, possess luminescent properties. https://onlinelibrary.wiley.com/doi/full/10.1002/ange.202401872
Trace and Minor Element Analysis of Azurite Blues in Fine Arts: Possibilities and Limitations in Provenance Studies
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 […]
