Global and Local Shielding/Deshielding Variation in C60 and C70 Fullerenes Upon Reduction: Evaluation of Aromaticity, 13C‐NMR and Anisotropy Patterns

Chemistry – A European Journal, Volume 31, Issue 12, February 25, 2025.
The six‐fold reduction of C60 and C70 fullerenes modifies the magnetic response of the π electrons enabling global and local variations of shielding/deshielding regions along different orientations of the external field which are represented in the variations of 13C‐NMR shifts given by the σ33 shielding component under the principal axis system (PAS ...

Designing cities for everyday nature

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract The motivations for incorporating nature into the design of cities have never been more compelling. Creating experiences with nature that occur every day (everyday nature) in cities could help reverse the fate of many threatened species and connect people with nature and living cultural traditions.

Borospherene in the Nanohoop: Complexation and Aromaticity of Neutral and Dioxidized Cycloparaphenylene Supramolecules with B40 and C60 Fullerenes

Chemistry – A European Journal, Volume 30, Issue 49, September 2, 2024.
[9]‐ and [10]‐Cycloparaphenylenes encapsulate borospherene B40 forming host‐guest complexes with comparable complexation energy to carbon fullerenes, exhibiting double host‐guest aromaticity at the dioxidized state. Abstract Supramolecular complexes of carbon nanohoops with fullerenes play a key role for the design of novel nanomaterials with ...

Green Synthesis of Stable Sub‐Nano Silver Clusters with Potential against Cancer

Journal of Nanomaterials, Volume 2024, Issue 1, 2024.
Sub‐nano‐sized Ag‐clusters represent an intermediate class between isolated atoms and nanoparticles, and they can possess new, unexpected properties differing from bulk and nano‐sized particles. A simple, fast, one‐step, cost‐effective protocol was revealed to prepare stable sub‐nano‐sized Ag‐clusters with green synthesis.
