Programming the Optoelectronic Properties of Atomically Precise Gold Nanoclusters Using the Conformational Landscape of Intrinsically Disordered Proteins

Chemistry – A European Journal, EarlyView.
ABSTRACT The rational design of hybrid nanomaterials with precisely controlled properties remains a central challenge in materials science. While atomically precise gold nanoclusters (Au‐NCs) offer molecule‐like control over a metallic core, tuning their optoelectronic behavior via surface engineering is often empirically driven.

Photocatalyzed Ring Expansion of α‐Ketosulfonylaziridines: Ready Access to δ‐Sultams

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A novel radical–polar crossover (RPC) photoredox‐catalyzed reaction for the synthesis of δ‐sultams from N‐sulfonyl α‐ketoaziridines through a controlled ring opening–expansion process is presented. This method allows the easy access to sultams with an unprecedented substitution pattern in up to 85% yield and 2:1 d.r., and highlights the potential of ...

Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

Frugivory‐mediated trophic cascades: how apex predators can shape the recruitment of a fleshy‐fruited tree

Oikos, EarlyView.
The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.
