High‐Power Performance of Textured Piezoelectric Ceramics Through Synergistic A‐Site Donor and B‐Site Acceptor Doping

Small Methods, EarlyView.
A/B‐site co‐doping combined with templated grain growth enables synergistic defect and domain engineering in textured PIN–PMN–PT ceramics. The approach simultaneously enhances piezoelectric response and mechanical quality factor, achieving a balanced soft–hard characteristic.

Effects of Exposure to Radiation and Steam on Silicone Rubber Cables Removed From a Nuclear Power Plant

High Voltage, EarlyView.
ABSTRACT Low‐voltage cables insulated with silicone rubber were harvested from three locations in the primary containment vessel of a boiling water nuclear power plant (NPP). Subsequently, the cable, which was placed in an ambient environment with a relatively higher temperature and the highest rate, was cut into four shorter ones.

The Breakdown and Self‐Clearing Performance During the Energy Harvesting Process of Dielectric Elastomer Generators Using Single‐Walled Carbon Nanotubes Electrodes

High Voltage, EarlyView.
ABSTRACT For dielectric elastomer generators (DEG), electrical breakdown is the main failure mode during their working cycle. The application of self‐clearing electrodes is of great significance to avoid a single breakdown leading to the failure of the entire generator.

Investigation of the Simplified Equivalent Circuit Model of the Post‐Arc Sheath Stage in DC Vacuum Circuit Breakers

High Voltage, EarlyView.
ABSTRACT This paper presents a simplified equivalent circuit model (ECM) for the post‐arc sheath stage in DC vacuum circuit breakers and outlines the method for calculating circuit parameters using the particle‐in‐cell Monte Carlo collision (PIC‐MCC) method. The post‐arc sheath is modelled as a parallel combination of a variable resistor and a variable
