A Homobimetallic Frustrated Lewis Pair Cobalt Catalyst for the Methanolysis of Hydrosilanes

open access: yesAngewandte Chemie, Volume 137, Issue 36, September 1, 2025.
The bimetallic Co(I)/Co(–I) complex [Co(CO)2(κ3‐P,N,P‐PNHP)][Co(CO)4] shows excellent activities in the methanolysis of hydrosilanes, reaching TOF values of ca. 50 000 h−1. This behavior can be ascribed to the presence of the [Co(CO)4]– anion, which allows for a frustrated Lewis pair mechanism, resulting in a low energy pathway for the heterolytic ...

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

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 7, 2 March 2026.
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.

Blocked and “Unblocked” Learning: Structural Factors That Impede and Enable Evidence‐Informed Policymaking

open access: yesEuropean Policy Analysis, Volume 12, Issue 2, Spring 2026.
ABSTRACT This article addresses a critical issue in evidence‐informed policymaking: the challenge of translating knowledge into policy outputs amidst the complex interplay between research and politics. It discusses the concept of “blocked learning,” where individual‐level learning fails to scale up to organizational and policy levels, thus impeding ...

Wildland–urban interface expansion: Towards comprehensive planning processes

open access: yesPeople and Nature, Volume 8, Issue 3, Page 754-766, March 2026.
Abstract Wildland–urban interface (WUI) expansion is accelerating in numerous regions around the world due to increasing amenity‐led migration processes, defined as the movement of people seeking higher environmental quality. While WUI areas are complex social–ecological systems requiring holistic planning and management, they are usually approached ...

Astrocyte Senescence Impairs Synaptogenesis due to Thrombospondin‐1 Loss

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Senescent hippocampal astrocytes lose TSP secretion, impairing excitatory synaptogenesis via the α2δ‐1 pathway. Restoring TSP‐1 rescues synaptic formation, revealing the contribution of astrocyte senescence to age‐related hippocampal synaptic decline.
