Pulsed MPI Relaxometry of Brownian and Néel Field‐Dependent Relaxation in Superparamagnetic Magnetite Nanoparticles Confirm Theory and Simulations

Small, Volume 20, Issue 44, November 1, 2024.
Superparamagnetic iron oxide nanoparticles (SPIOs) are crucial tracers in Magnetic Particle Imaging (MPI), impacting imaging contrast, resolution, and sensitivity. Brownian and Néel relaxation theory from the 1950s suggests relaxation times vary with particle size, shell thickness, viscosity, and field strength.

Systematic approach to a government‐led technology roadmap for future‐ready adaptive traffic signal control systems

Systems Engineering, Volume 27, Issue 6, Page 1062-1088, November 2024.
Abstract The economic impact of inefficient traffic control systems is significant owing to prolonged commute durations, and increased energy consumption. Traffic signal control systems (TSCSs) significantly influence traffic flows at intersections. Therefore, adaptive TSCSs (ATSCSs) that can adjust to traffic conditions in real‐time have been proposed

Failure mechanism of metallized film capacitors under DC field superimposed AC harmonic: From equipment to material

High Voltage, Volume 9, Issue 5, Page 1081-1089, October 2024.
Abstract This study focuses on the degradation behaviour of metallised film capacitors, which are the essential components for the stability of converter valves in flexible ultra‐high voltage direct current (HVDC) transmission systems. Through systematic experimentation, we investigated the failure mechanisms of MFCs under HVDC fields with superimposed
