Signal Extraction and Clustering of Partial Discharge in Motor Insulation Using Temporal Correlation‐Based Clustering

High Voltage, EarlyView.
ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...

Study on the Coupled Effects of High‐Speed Airflow and Charged Sand on Power‐Frequency Discharge Characteristics of Conductor–Tower Gaps in Strong Wind–Sand Environments

High Voltage, EarlyView.
ABSTRACT Strong wind–sand weather in Xinjiang threatens power grid safety by increasing transmission line tripping risks. Existing studies focus on sand polarization but neglect the coupled influence of high‐speed airflow and charged sand on gap discharge characteristics.

Investigation of the Partial Discharge Inception and Flashover With IEC‐Based Comparative Tracking Index Electrodes and Comparison With Homogeneous and Inhomogeneous Electric Fields at Varying Pressures for Aerospace Applications

High Voltage, EarlyView.
ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.

Probing skin photoallergens in reconstructed human epidermis: An EPR spin trapping investigation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 275-281, March/April 2025.
We present an original proof‐of‐concept methodology to probe radical generation from allergens in contact with photoexposed skin, using electron paramagnetic resonance and spin trapping in a reconstructed human epidermis model mimicking real‐life exposure scenarios.

Two‐phase ammonia plume behavior in a still room: Jack Rabbit III chamber studies

Process Safety Progress, Volume 45, Issue 3, Page 301-312, September 2026.
Abstract This paper describes a new set of 45 laboratory experiments where about 180 g of ammonia was released from pressurized liquefied storage in a still 51.3 m3 chamber (i.e., a small room) and the variations of the ammonia gas concentrations and liquid deposition over a 60 min time period were investigated.

Photolytic Hydrophosphination: Insights Into Catalyzed and Uncatalyzed Processes

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
Catalyst‐free photolytic hydrophosphination is demonstrated for vinyl arenes and activated alkenes in polar protic (alcohol) solvents. These reactions appear to be closed‐shell, affirming that even ambient light can impact a reaction—a potentially broad influence on even mundane reactions.

Magnetic Field Disturbance Induced by the Enhanced Suprathermal Ring Current in the Magnetosphere of Saturn

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Saturn's ring current, which modulates the global magnetic field configuration, varies dynamically with hot plasma injections. However, quantifying transient magnetic field disturbances remains challenging in the absence of in situ measurements on Saturn's surface.
