Quality and reliability of short videos about type A aortic dissection on Bilibili and TikTok: a cross-sectional study
Abstract Background: Type A aortic dissection (TAAD) is a life-threatening cardiovascular emergency. Short-video platforms such as TikTok and Bilibili have become important channels for health information dissemination, but the quality and reliability of TAAD-related videos remain unclear. Objective: This study aimed to evaluate the quality and reliability of TAAD-related short videos on TikTok and Bilibili, with particular attention to platform differences and uploader characteristics.
Continuously graded-doped SnO 2 for efficient n–i–p perovskite solar cells
Abstract Conventional n–i–p architecture remains a robust platform for scalable perovskite photovoltaics1,2, yet its steady-state efficiency has stagnated at ~26% (ref.3), lagging behind p–i–n counterparts4. This performance gap arises from persistent non-radiative recombination at textured electron transport layer (ETL)/perovskite interfaces, yet the underlying physical origin remains unclear.
Author Correction: Gate tuning of coupled electronic and structural phase transition in atomically thin Ta 2 NiSe 5
Correction to: Nature Communications https://doi.org/10.1038/s41467-025-66594-y, published online 9 December 2025 In the version of the article initially published, the Fig. 3f y-axis label was “Energy gap (meV)” but should have been “Energy gap (eV)”. This error has now been corrected in the HTML and PDF versions of the article.
Efficient white light-emitting diodes based on all-perovskite triple-junction tandems
Abstract Triple-junction tandem light-emitting diodes (LEDs) with simultaneous red, green and blue emission are ideal back-lights for next-generation ultrahigh-definition displays.
Rotator Cuff Impingement Damages the Organelles of Tenocytes, Resulting in Excessive Tenocyte Apoptosis and Tendinopathy
Abstract References Supplementary Material Get access More Cite Share options Information, rights and permissions Metrics and citations Abstract Background: Rotator cuff impingement syndrome is a prevalent cause of supraspinatus tendinopathy, resulting in considerable pain and functional impairment. Excessive apoptosis of tenocytes has been recognized as a critical pathological mechanism in both supraspinatus tendinopathy and rotator cuff tears.
Robust perovskite nanocrystal emitters
Perspective Materials Science Hierarchical shells stabilize soft and labile metal halide perovskite surfaces for screen displays Keyu Wei and Mingjian YuanAuthors Info & Affiliations Abstract The vibrant colors of a screen display come from precise mixing of red, green, and blue (RGB) light, which creates a broad spectrum of hues. A key component enabling this technology is a color-converting material that absorbs highenergy light at a specific wavelength and emits RGB light.
Chemical Differentiation and Quantitative Analysis of Black Ginseng Based on an LC-MS Combined with Multivariate Statistical Analysis Approach
Abstract : Black ginseng is a new type of processed ginseng that is traditionally used in herbal medicine in East Asian countries. It is prepared from fresh, white, or red ginseng by undergoing a process of steaming and drying several times. However, the chemical differentiation of black ginseng with different processing levels is not well understood. The aim of this study was to propose a new method for discriminating and quantifying black ginseng.
Unraveling Size‐Dependent Ion‐Migration for Stable Mixed‐Halide Perovskite Light‐Emitting Diodes
Research Article This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record. Please cite this article as https://doi.org/10.1002/adma.202304094 Abstract Mixed-halide perovskites show tunable emission wavelength across the visible light range, with optimum control of the light color.
