Advanced Materials, EarlyView.Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion
Advanced Materials, EarlyView.This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

Advanced Materials, EarlyView.The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.
