Nondestructive testing systems with magnetic flux leakage (MFL)
, 2016 Paper P100, 1 S.Ferromagnetic components used in mechanical, automotive and civil engineering are mostly subject to high mechanical loads. Cracks, which may form during manufacture or in use, may lead to a complete failure of the component in the worst ...

Advanced Functional Materials, EarlyView.A high‐Zn2+‐transference hydrogel electrolyte of ex‐PDADAM is developed via anion exchange at quaternary ammonium sites, achieving high Zn2+ transference number (0.86), ionic conductivity (8.10 mS cm−1), and toughness (51.25 MJ m−3). Symmetric cells are operated stably for over 2000 h, while flexible pouch cells retain 90.9% capacity after 300 cycles ...

Interface Effects in Ultrathin Silicon on Insulator Films
Advanced Functional Materials, EarlyView.This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Advanced Functional Materials, EarlyView.A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

The Effects of Magnetizer Velocity on Magnetic Flux Leakage Signals
, 1993 In many magnetic flux leakage applications, the nondestructive inspection constraints suggest the use of high inspection velocities. However, high inspection velocities can compromise the ability to detect and characterize defects.
