Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

Angewandte Chemie, EarlyView.
Four heavy Hg(II) coordination networks with paramagnetic Fe(II) sites reveal strong and halogen‐tunable low‐frequency (LF) sub‐terahertz phonons and field‐dependent magnetic transitions. LF phonon spectroscopy and Raman magnetospectroscopy are powerful probes of structure, low‐energy vibration, zero‐field splitting, and spin–phonon coupling supported ...

Reinforcement Learning With a Low‐Cost Parallel Linkage Gripper for Static and Dynamic Planar In‐Hand Manipulation

Advanced Intelligent Systems, EarlyView.
Hardware‐learning co‐design combines volar‐plate‐inspired passive‐joint constraints with mechanism‐aware reinforcement learning for a low‐cost parallel‐linkage gripper. The resulting system performs quasi‐static object adjustment and dynamic pinch grasping, demonstrating reliable planar in‐hand manipulation and successful sim‐to‐real transfer. Parallel

Design of Giant Negative Thermal Expansion Based on a Fluorite Structure

Angewandte Chemie, EarlyView.
Ba[B(CN)4]2 with a fluorite structure possessing a large average atomic volume was successfully synthesized for the first time. In situ powder X‐ray diffraction measurements revealed that Ba[B(CN)4]2 exhibits giant negative thermal expansion (NTE) behavior through non‐rigid unit modes with strongly negative Grüneisen parameters.

Beyond the Camera: Epidermal Sensor Platforms for Intelligent Facial Expression Recognition and Interactive Human Monitoring

Advanced Intelligent Systems, EarlyView.
Skin‐conformal epidermal sensors enable camera‐free intelligent facial monitoring by converting facial deformation and muscle activity into electrical signals through piezoresistive, capacitive, electrophysiologic, and self‐powered mechanisms. Coupled with artificial intelligence (AI), these platforms support facial expression recognition, human ...

Flying Through Cluttered and Dynamic Environments With Light Detection and Ranging

Advanced Intelligent Systems, EarlyView.
A LiDAR‐based navigation system enables UAVs to autonomously fly through cluttered environments while avoiding high‐speed dynamic obstacles. With a total module computation latency of about 12.28 ms and the worstcase perception‐to‐action latency of around 22 ms theoretically, the system successfully avoids obstacles of diverse sizes, geometries, and ...
