Investigation of Dielectric and Thermal Properties of Mineral Oil‐Based Fe3O4‐Coated SiO2 Core‐Shell Nanofluids

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study investigates the dielectric and thermal properties of transformer oil‐based nanofluids incorporating Fe3O4‐coated SiO2 core–shell nanoparticles as nanofillers. The nanoparticles were synthesised with varying shell thicknesses, and two samples underwent surface treatment.

Accounting for white matter uptake improves between tracer agreement in amyloid PET

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION Amyloid positron emission tomography (PET) allows in vivo measurement of amyloid plaque deposition; however, different tracers lead to different results. We test the hypothesis that the variability in amyloid measurements is related to white

Breakdown and Discharge Characteristics of High Repetition Frequency Nanosecond Pulsed Air Dielectric Barrier Discharge

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores the breakdown characteristics and discharge modes in a parallel plate air dielectric barrier discharge system using repetitive nanosecond pulses, with pulse repetition frequencies (PRFs) from 0.1 to 100 kHz. It examines how pulse parameters—PRF, pulse number and gas pressure—affect the memory effect, leveraging current and ...
