Synthesis and One‐Electron Reduction of Donor‐Acceptor‐Stabilized SiII–EII–SiII Trimetallylenes (E = Ge, Sn, Pb)

Angewandte Chemie, EarlyView.
The first isolable trimetallylenes (SiII)2EII (E = Ge, Sn, Pb) with pπ‐type silanylidenyl donors have been synthesized, having donor–acceptor electronic structures that give rise to near‐infrared absorption and enable access to bis(silanylidenyl)‐supported GeI and SnI radical anions upon one‐electron reduction with elemental potassium.

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System

Advanced Science, EarlyView.
An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Two‐Dimensional Quaternary Alloys of (RuMoVNb)Se2 for Superior Hydrogen Evolution Reaction Catalysis

Advanced Science, EarlyView.
Composition‐tuned (RuMoVNb)Se2 quaternary alloy nanosheets are synthesized via colloidal reactions. Incorporation of Ru into (MoVNb)Se2 ternary alloys results in more metallic electronic structures and significantly enhances their electrocatalytic activity for the hydrogen evolution reaction (HER) under alkaline, acidic, and neutral conditions.

Azole γ‐Peptides Helix Switching via Heterocycle Substitutions

Angewandte Chemie, EarlyView.
Heterocycle substitution in azole‐based γ‐amino acids enables control over the helical shape of heterocyclic γ‐peptides. S↔N permutation in thiazole residues switches a canonical 9‐helix into a flexible helix exhibiting discontinuous hydrogen bonding.

Exfoliated‐MoS2 Gradual Resistive Switching Devices as Artificial Synapses

Advanced Electronic Materials, EarlyView.
A vertical memristor based on untreated, exfoliated MoS2 is presented, revealing gradual resistive switching governed by Schottky barrier modulation at the MoS2/metal interface from the trapping/detrapping of charges. Furthermore, the device emulates synaptic‐like plasticity functions, including: potentiation, depression, and spike‐amplitude‐dependent ...

Charge Transport in All‐Inorganic CuInSe2 Nanocrystal Transistors: Linking Material Design and Device Performance

Advanced Electronic Materials, EarlyView.
This work explores how colloidal CuInSe2 nanocrystals form functional field‐effect transistors when their native ligands are replaced with short inorganic species that promote charge transport. By systematically adjusting nanocrystal dimensions, surface treatments, film characteristics, and device architecture, the study maps the resulting electronic ...
