Dual Resonant Plasmonic Infrared Pixels for Selective Optical Encoding
Advanced Materials Technologies, EarlyView.This study presents dual‐resonant plasmonic nanostructures for advanced optical encoding in the mid‐infrared. By optimizing plasmonic resonances in nano‐antennas within ring cavities, selective and simultaneous tunability in both the MWIR and LWIR regions is achieved.

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining
Advanced Materials Technologies, EarlyView.Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.

Magnetic Steganography Based on Wide‐Field Diamond Quantum Microscopy
Advanced Optical Materials, EarlyView.This document illustrates magnetic steganography. Magnetic graphics, including pixel art and QR codes, are produced using magnetic materials (such as Ni) and obscure behind patterns manufactured using non‐magnetic materials (such as Au), which are unveiled through widefield quantum microscopy. Furthermore, manipulating the electron spin of NV with dual

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis
Advanced Science, EarlyView.Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...
