A Mechanistic Blueprint for Fast, High‐Yield Green Scintillators Using Conjugated Polymer–Nanocrystal Composites

Advanced Functional Materials, EarlyView.
Conjugated polymer–nanocrystal composites are investigated to develop fast, high‐yield green scintillators. The polymer F8BT enables efficient, ultrafast emission, while blends with non‐emitting HfO2 nanocrystals and luminescent CdZnS/ZnS quantum dots reveal distinct sensitization mechanisms.

Design and implementation of a high-frequency inverter with wide soft-switching range for dynamic wireless charging of electric vehicles

Wireless Power Transfer
To solve the problem that wireless power transfer (WPT) systems with multiple transmitters require more inverters and involve complex phase synchronization control between inverters, a dual-output zero-voltage switching (ZVS) inverter is proposed. It can
