Synergistic Regulation of High Dielectric Constant and H‐Aggregation for Efficient and Thickness‐Tolerant Organic Solar Cells

ABSTRACT While the power conversion efficiency (PCE) of organic solar cells (OSCs) has advanced rapidly, their sensitivity with respect to active layer thickness hinders industrial fabrication. Herein, a novel acceptor BMD‐6F was synthesized via molecular engineering of L8‐BO, wh...

Revisiting and Improving Soil Surface Resistance Schemes for Land Surface Modeling

Abstract Accurate representation of soil evaporation is critical for understanding land‐atmosphere interactions and improving climate simulations, where soil surface resistance plays a key regulatory role. However, existing schemes differ substantially and lack systematic evaluat...

Social Support and Chemistry Learning Engagement: Chain Mediation and Latent Profile Analysis of Chemistry Self-Efficacy and Chemistry Anxiety

Abstract Chemistry learning engagement plays an important role in students’ academic development and sustained motivation to learn chemistry. Although previous studies have examined the relationships of perceived social support, self-efficacy, and anxiety with students’ learning...

Low-intensity fire-derived pyrogenic carbon decouples methane and carbon dioxide production in aerobic and hypoxic layers of permafrost peatlands

Wildfire frequency is increasing in high-latitude permafrost peatlands, leading to the input of pyrogenic carbon (PyC) into the active layer. The effect of PyC on the critical greenhouse gases CH 4 and CO 2 production in the active layer (aerobic and hypoxic) is poorly constraine...

scLTF: A self-training clustering framework for large-scale single-cell RNA-Seq data

Single-cell RNA sequencing (scRNA-seq) technology has rapidly advanced in recent years, driving significant breakthroughs in developmental biology, cancer research, immunology, and other related fields. However, existing clustering methods still face performance bottlenecks when...

H 2 SO 4 catalyzed tandem alkylation-hydrolysis reaction of β -ethylthio- β -indolyl- α , β -unsaturated ketones and alcohols: Feasible synthesis of α -alkylated 3-aroylacetylindoles and 3-arylpropionylindoles

H2SO4 catalyzed tandem alkylation-hydrolysis reaction of β-ethylthio-β-indolyl-α, β-unsaturated ketones and alcohols has been developed to access α-alkylated 3-aroylacetylindoles in up to 90% yield. Subsequent debenzoylation of α-alkylated 3-aroylacetylindoles in the presence of...

Levosimendan can effectively reduce myocardial cell apoptosis caused by hypoxia through antioxidant activity

Abstract Levosimendan (LMSD) is a novel positive inotropic drug with unique chemical structure and pharmacological properties. It has multiple effects such as dilating blood vessels and improving myocardial diastolic function, and is widely used in the treatment of cardiovascular...

Seasonal dynamics of aquatic organic carbon driven by floating-mat formation in a terrestrializing lake

Lakes are important components of the land carbon cycle, but how floating mats during lake terrestrialization reshape aquatic organic carbon remains unclear. Here we show, using seasonal field observations, carbon isotope tracing, and structural equation modelling, that floating...

Level of education is associated with risk of kidney diseases in middle-aged and elderly adults: evidence from the CHARLS

Although numerous studies have indicated that various socioeconomic factors influence the risk of developing kidney disease, clinical evidence regarding the relationship between level of education (LoE) and the risk of kidney disease remains insufficient. This study aims to evalu...
