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.

Manganese‐Based Spinel Cathodes: A Promising Frontier for Solid‐State Lithium‐Ion Batteries
Advanced Materials, EarlyView.Mn‐based spinel cathodes LiMn2O4 (LMO) and LiNi0.5Mn1.5O4 (LNMO), with the unique characteristics of low cost, structural stability, and 3D Li‐ion diffusion channels, have presented great potential in all‐solid‐state batteries. Here, a comprehensive understanding and valuable insights into the rational design and implications for the future development

High Transconductance on Thiophene‐Based Vertical Organic Electrochemical Transistors
Advanced Materials Technologies, EarlyView.Vertical organic electrochemical transistors (vOECTs) fabricated with the organic mixed ionic‐electronic conductors poly(3‐hexylthiophene‐2,5‐diyl) (P3HT) and poly(3‐[2‐[2‐(2‐methoxyethoxy)ethoxy]ethyl]thiophene‐2,5‐diyl) (P3MEEET) demonstrate excellent performance, exhibiting high transconductance, large on‐currents, and high on/off ratios.

Tunable Mass Transport and Enhanced Electrochemical Performance of CO2 Laser Engraved Electrodes
Advanced Materials Technologies, EarlyView.This work introduces vector‐mode CO2 laser engraving as a rapid strategy to fabricate electrochemical sensors with tunable mass transport. Spiral electrodes can behave as disk electrodes, outperforming conventional raster‐engraved devices in current density and sensitivity.
