Light‑Driven Propulsion of Graphene Aerogels in Microgravity

Advanced Science, EarlyView.
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Concurrently Achieving 4.6 W/M2 and 120,000 Cyclability Enabled by Extendable Swing Arms in Rotational Triboelectric Nanogenerator

Advanced Science, EarlyView.
A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

Zero Thermal Expansion and Local Structure in KxMnxFe2‐xMo3O12‐Based Materials

Advanced Science, EarlyView.
Local structure engineering via ion insertion drives local structural transformation from low‐symmetry P21/a to high‐symmetry R‐3c, enhancing structural flexibility and realizing a transition from positive thermal expansion to wide‐temperature‐range zero thermal expansion in KxMnxFe2‐xMo3O12‐based materials.

Self‐Powered Bearing Sensing and Real‐Time Fault Diagnosis Enabled by Non‐Invasive Triboelectric Sensors and Edge AI Acceleration

Advanced Science, EarlyView.
This study achieves the synergistic integration of self‐powered sensing and edge AI acceleration to establish a real‐time fault diagnosis system. The proposed TENG‐based self‐powered bearing sensor (NSE‐TBS) and FPGA‐accelerated edge AI framework fundamentally break through the inherent limitations of conventional monitoring systems, including complex ...
