Sustainable PEG‐Based Shape‐Stabilized Phase Change Materials Using Raw Pine Cone as a Low‐Cost Filler and Graphite for Enhanced Thermal Conductivity

Polymer Engineering &Science, EarlyView.
Preparation of sustainable PEG‐based ssPCMs using a PC‐based low‐cos filler and G as a thermal enhancer. PEG 6000 is incorporated into the PC/G matrix through mixing to obtain the shape‐stabilized PCM for thermal energy storage applications. ABSTRACT This study investigates the development of a novel shape‐stabilized phase change material (ssPCM ...

Nitrogen‐Doped GeTeS Ovonic Threshold Switching Selector With Optimized Performance Trade‐Off for 1S–1R Phase‐Change Memory

Small, EarlyView.
This study introduced a Ge‐Te‐S co‐sputtering process to resolve the performance trade‐off between GeTe and GeS in OTS selector devices, and improved device durability through nitrogen doping. Furthermore, in a 1S‐1R structure incorporating phase‐change memory devices, it simultaneously achieved excellent thermal stability, durability, high‐speed ...

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...
