Advanced Science, EarlyView.This paper presents a programmable metasurface‐based Meta Key Distribution (MKD) system for secure, protocol‐independent key exchange in indoor wireless settings. By embedding entropy into the wireless channel, it enables lightweight, compatible cryptographic key generation.

Advanced Science, EarlyView.Two microwave‐assisted synthetic methods, specifically a one‐pot and a seeded‐growth approach, are developed within a hydroalcoholic solution for the growth of single‐phase ternary WxTi1‐xO2 and heterostructured TiO2‐WO3‐x colloidal nanocrystals. Both types of nanocrystals show significant photocatalytic activity for 4‐methoxybenzyl alcohol oxidation ...

Optically Driven Formation of Tailored Phonon Cavities
Advanced Science, EarlyView.It is demonstrated that a structured optical field creates nanoscale “phonon cavities” in van der Waals materials, where atomic vibrations are confined and controlled in space and time. This approach enables programmable control of cavity geometry, symmetry, and frequency, and provides a platform for ultrafast studies of nonequilibrium interactions and

Magnetic and Crystal Symmetry Control on Spin Hall Conductivity in Altermagnets
Advanced Science, EarlyView.Crystal structures and schematic illustrations of the spin Hall effect (SHE) in altermagnets. High‐symmetry RuO2 exhibits conventional SHE, while tilted RuO2 shows trivial unconventional SHE (USHE) caused by structural tilting. CrSb and MnTe, with reduced magnetic symmetry, display intrinsic USHE arising from symmetry‐driven spin–momentum locking ...
