Advanced Science, EarlyView.A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Molecular Conversion of Thermally Stable Cu‐Ag Networks for Mechanically Robust Printed Electronics
Advanced Science, EarlyView.An air‐processable Cu–Ag reactive ink enables in situ formation of an Ag‐surface‐enriched Cu conductive network. Optimized Ag distribution suppresses Cu oxidation while preserving continuous electrical pathways, allowing printed conductors to achieve high conductivity, reduced migration, and stable operation at extreme temperatures up to 800 °C in air.

Advanced Intelligent Systems, EarlyView.This work presents an inchworm‐like dual‐balloon‐assisted colonoscopic robot (IDCR) based on a rod‐driven two‐segment continuum section. The IDCR enables the active straightening of the sigmoid colon through an inchworm‐like locomotion strategy, thereby avoiding loop formation.

Shape Sensing, Mapping, and Obstacle Avoidance of the Continuum Manipulator in Confined Environments
Advanced Intelligent Systems, EarlyView.An integrated sensing framework combines capacitive sensors, IMU, and laser array sensor. The shape reconstruction is finished by backpropagation neural network. Accurate shape estimation (relative error of 1.04%) is maintained under a 110 g tip load, while a miniaturized VL6180X array enables local environmental reconstruction and reactive obstacle ...
