Advanced Optical Materials, EarlyView.Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Root‐Stimulated Movements in Mimosa Pudica for Biohybrid Robotic Systems
Advanced Robotics Research, EarlyView.This study demonstrates that thermal and electrical stimulation of Mimosa pudica root induces movement of the petiole and pinnules without direct stimulation of the aerial organs, thereby enabling a plant‐based robotic gripper and providing a foundation for the development of intelligent and sustainable systems.

Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics
Advanced Robotics Research, EarlyView.Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

Jets from a stellar-mass black hole are as relativistic as those from supermassive black holes
International audienceRelativistic jets from supermassive black holes in active galactic nuclei are amongst the most powerful phenomena in the universe, acting to regulate the growth of massive galaxies. Similar jets from stellar-mass black holes offer a
