Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review
cMat, Volume 2, Issue 2, June 2025.ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

High Voltage, Volume 10, Issue 3, Page 615-622, June 2025.Abstract CF4 is a major decomposition product of the insulating gas in C4F7N‐insulated gas‐insulated metal‐enclosed switchgear (GIS) during partial discharge or overheating faults. Its detection is essential for effective online monitoring and fault diagnosis of GIS.

High Voltage, Volume 10, Issue 3, Page 660-672, June 2025.Abstract Within 30 min after live operation of gas‐insulated switchgear (GIS), more than 60% of discharge failures are caused by metallic particles. To address this issue, this study explored the vibration propagation mechanisms in GIS cavities and established an equivalent vibration transmission model.
