Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

High Voltage, EarlyView.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.

Trends in toxicological findings and drug seizures of MDMA in New Zealand from 2010 to 2022

Journal of Forensic Sciences, EarlyView.
Abstract 3,4‐Methylenedioxymethamphetamine (MDMA) or “ecstasy,” is a commonly used drug worldwide, including in New Zealand, where 4.8% of the population aged 15 years or over reported using it in a 2023/2024 survey. This study provides additional insights on MDMA prevalence data in New Zealand by reporting toxicology data from Coronial and driving ...
