Heterointerface‐Functionalized Photoelectric Response of Metal‐Oxide Schottky Photodiode for Intelligent Fire Detection

Advanced Science, EarlyView.
A heterointerface‐functionalized Schottky photodiode (HF‐SPD) is developed to explore the photoelectric capabilities of low‐temperature oxide semiconductors. Besides the remarkable UV detection capability, the bias‐tunable photo response endows HF‐SPD with the unique wavelength selectivity.

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

Advanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Thermal Cyclotrimerization Bridges Polymer‐Filler Interfaces for High‐Performance CO2 Separation Membranes

Advanced Science, EarlyView.
Thermal cyclotrimerization of nitriles converts interfacial discontinuity in MAF‐stu‐1/PIM‐1 MMMs into a continuity‐enhanced junction. Triazine–Zn2+ coordination between TR‐PIM chains and MAF‐stu‐1, together with hydrogen bonding and π–π stacking, lowers interfacial tension and builds selective CO2 pathways, enabling > 10 000 barrer CO2 permeability ...
