Emergence of Unconventional Magnetic Order in Strain‐Engineered RuO2/TiO2 Superlattices
Advanced Science, EarlyView.Epitaxial strain activates unconventional magnetism in rutile RuO2, absent in bulk or relaxed RuO2. Polarized neutron reflectometry with atomic‐layer resolution directly reveals finite magnetization confined to RuO2 layers in fully strained RuO2/TiO2 superlattices on TiO2 (110).

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Achievable directive antenna gain measurements and modeling for 60 GHz indoor links
Scientific ReportsHighly directive antennas may be a key component in millimeter wave links to offset their inherently high path losses. In cluttered scenarios such as Non-Line-Of-Sight (NLOS) indoor settings, antenna gain is degraded by the interaction of the channel ...

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Advanced Electronic Materials, EarlyView.Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

A Full Physical Strategy for Electrical Contacts on Laser‐Induced Graphene (LIG) Electrodes
Advanced Electronic Materials, EarlyView.A fully dry fabrication strategy combining PVD and dual‐laser processing enables direct integration of laser‐induced graphene with metallic current collectors. Ultralow Au‐LIG contact resistance is achieved without binders, adhesives, or chemical treatments, while preserving electrochemical performance.

Chemical Switching Between B2N and B2C Homoaromaticity
Angewandte Chemie, EarlyView.We report the synthesis of homoaromatic 1‐aza‐2,4‐diazadiboretane with a bicyclic four‐membered NB2C motif and demonstrate experimentally and theoretically that the homoaromatic delocalization can also be chemically shifted from the B2N to the B2C moiety by deprotonation of the ring carbon atom.

Advanced Electronic Materials, EarlyView.Flexible transparent electronics require efficient power management without sacrificing visibility or mechanical compliance. This work presents a room‐temperature‐fabricated amorphous Ga2O3/NiO heterojunction diode on a flexible substrate that enables full‐wave rectification, UV photovoltaic energy harvesting, and self‐powered photodetection.
