Functional Segregation of Epileptogenicity within the Human Amygdala

open access: yesAnnals of Neurology, EarlyView.
Objective In temporal lobe epilepsy (TLE), the amygdala in the epileptogenic network is underestimated compared to other regions such as the hippocampus. Recent advances in anatomical neuroimaging and stereoelectroencephalography (SEEG) signal analyses could help better understand the involvement of the different amygdala nuclei in the genesis of ...

Bent N‐Heterocyclic Allenes From a Well‐Defined Titanium Vinylidene Complex

open access: yesAngewandte Chemie, EarlyView.
The syntheses and the structures of N‐heterocyclic allenes are reported. Allenes bearing fluorenylidene capping groups show markedly bent C═C═C units, a carbene‐like reactivity, and they can act as potent C‐donor ligands for metal complexes. ABSTRACT Allenes typically display a linear geometry. A notable exception occurs in allenes bearing two electron‐

1,4‐Digermacyclopenta‐1,3‐diene: Continuous Cyclic σ*–π Delocalization Enables Aromatic Stabilization in a Heavy‐Element 4π System

open access: yesAngewandte Chemie, EarlyView.
A five‐membered digermacycle exhibits an unusual 4π electron delocalization enabled by σ*(Ge–C)–π coupling within a nearly planar framework. Combined experimental and theoretical analyses reveal a continuous cyclic delocalization pathway, highlighting σ*–π interactions as a design principle for aromatic stabilization beyond classical π‐conjugated ...

Spin‐State Modulation of Atomic Iron Sites Enables Efficient CO2 Electroreduction in Acid Medium

open access: yesAngewandte Chemie, EarlyView.
An axial oxygen ligand was added to shift the spin state of the single‐atom Fe site from low to medium spin. This change reduces the interfacial interaction with H3O+ and decreases the *CO desorption energy, thus enhancing CO2RR in acidic media.
