Origins of Graphite Resistivity: Decoupling Stacking Fault and Rotational Misorientation
Advanced Science, EarlyView.Interfacial dislocations critically influence interlayer transport in van der Waals (vdW) materials, yet quantifying their individual contributions remains challenging. We measure graphite's c‐axis resistivity and develop a decoupling strategy, revealing a resistivity ratio of ∼4507:74:1 for rotational misorientations, stacking faults, and AB stacking,

Naked‐Eye Visual Warning of ppmv‐Level Fault‐Free Humidity Upper Limit
Advanced Science, EarlyView.In this study, based on the urgent need in many critical fields for ppmv‐level fault‐free humidity upper limit (ppmv‐FFHUL) monitoring, an innovative threshold gated humidity sensing technology was developed. It exhibits superior portability (as thin and light as paper) and highly economic feature (without auxiliary instruments at all), and can achieve

Advanced Science, EarlyView.Laser material processing is a promising technique for fabricating metal structures. Here, external electric field (EFs) assisted laser processing of metallic powders are investigated. EFs affect the melt tracks through changes in their stability and influence the grain structure in conjunction with laser intensity distribution methods. The EF‐assisted

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices
Advanced Science, EarlyView.This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Advanced Science, EarlyView.A single‐pulse approach uncovers trap dynamics in β‐Ga2O3 Schottky barrier diodes. Transient current profiling reveals rapid electron capture, delayed trap filling, and clear thermal effects. Extracted trap densities, capture time constants, and activation energies indicate that this simple pulse technique enables effective evaluation of trap states ...

MELEGROS: Monolithic Elephant‐Inspired Gripper with Optical Sensors
Advanced Science, EarlyView.MELEGROS is a monolithic, elephant‐inspired soft gripper integrating 3D‐printed optical sensors within a pneumatically actuated lattice. Simulation‐guided design decouples tactile and proprioceptive sensing. Characterized through grasping tests, MELEGROS can reach, scoop, and grasp, showcasing a paradigm where fully embedded sensing and continuous ...
