The Effects of Remanent Magnetization on Magnetic Flux Leakage Signals [PDF]

, 1995
The Magnetic Flux Leakage (MFL)Technique is the most commonly used technique to inspect large diameter transmission pipelines [1–5]. A typical MFL inspection system uses permanent magnets to apply an axially oriented magnetic field to the ferromagnetic ...

Analytical Method of Permanent Magnet Torque Machine with High Torque for Considering the Influence of Armature Magnetic Field

CES Transactions on Electrical Machines and Systems
Compared to the conventional permanent magnet synchronous machine (PMSM), the main characteristic of permanent magnet torque machine (PMTM) with high torque is that armature current is high, which has a great influence on magnetic circuit saturation, so ...

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.
