Heterobimetallic Pt(II) Complexes Supported by 1,8‐Naphthyridine Ligands Confirm the Rotation of C6F5 Groups about the Pt−C Bond

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
You Spin Me Round. The ligand 1,8‐naphthyridine is able to stabilize heterobimetallic complexes containing Pt(II)→M (M = Ag, Cu) donor–acceptor bonds, in which the rotation of the C6F5 ligands in solution can be stopped at low temperature. The ligand 1,8‐naphthyridine (napy) exhibits a rich coordination chemistry arising from the disposition of its two

Glutathione Threshold‐Triggered Selective Breakability of Organosilica Nanocapsules

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Replacing tetraethoxy orthosilicate (TEOS) by tetramethoxy orthosilicate (TMOS) as silica precursor to synthesize cleavable organosilica nanocapsules enabled the effective and selective entrapment of a positively charged protein as Cytochrome C (CytC) and a much more favorable breakability and kinetics release when exposed to high glutathione (GSH ...

Trait‐based species selection for restoration: A case study from tropical landscapes dominated by bracken

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results can be used by stakeholders to select the species best suited for active restoration projects in bracken‐dominated areas throughout the tropical region. Furthermore, our trait‐based approach, which considers seedling performance in disturbed areas, can serve as a guide for species selection in restoration programmes in other disturbed ...

Forest bird diversity increases with fragmentation per se in landscapes following forest gains

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results suggest that, at least for forest breeding birds, the benefits of habitat restoration to increase total forest area could be enhanced by distributing a given amount of restored habitat across multiple patches. Our study also highlights the overarching importance of habitat amount for biodiversity conservation. Taken together, these findings
