Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa
Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.
