Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Mechanistic Optimization of Pressure Transmission for Defect Mitigation in Thick‐Walled Aerospace‐Grade Polyetherimide

SPE Polymers, Volume 7, Issue 3, July 2026.
Gate freeze time (GFT) controls internal void formation in thick‐walled injection‐molded polyetherimide (PEI). Extending GFT by optimizing cooling time and mold temperature reduces void size from the baseline (large voids) to an optimized condition (voids reduced), as confirmed by ultrasonic C‐scan inspection.
