Charge transport manipulation of lead‐free perovskite A3Sb2X9 single crystal for stable and sensitive x‐ray detection

open access: yesInfoMat, EarlyView.
Low‐dimensional perovskites can effectively improve device stability and reduce leakage current, showing broad application prospects in the field of high‐energy radiation detection. In this work, high‐quality and large‐size lead‐free A3Sb2X9 single crystals were grown via a solution method, and the modulation mechanism of charge transport was ...

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Radiotherapy‐Induced Otitis Media With Effusion in Nasopharyngeal Carcinoma: A Meta‐Analysis

open access: yesThe Laryngoscope, EarlyView.
This meta‐analysis of eight studies comprising 582 NPC patients provides the first quantitative synthesis of radiotherapy‐induced otitis media with effusion (OME), demonstrating a significant overall risk difference of 0.18 (95% CI: −0.06 to 0.42, p < 0.0001) in OME naive ears.
