Mechanistic Insights Into Anionic Doping in O3‑Type Na(NiFeMn) 1/3 O 2 Cathode

ABSTRACT The lack of mechanistic guidelines hinders rational anionic doping in layered oxide cathodes for sodium‐ion batteries (SIBs). Using O3‐type Na(NiFeMn) 1/3 O 2 as a model and combining experiments with density functional theory (DFT) calculations, we reveal that doping ef...

Structural integrity facilitates multi-layer modulation of the brain-metabolome-microbiota network by Lilium lancifolium-derived vesicles in depression

Plant-derived vesicles (PDVs) have emerged as promising natural nanotherapeutics with multi-component cargo profiles and potential biological activity. However, their delivery behavior and mechanisms of action, particularly in complex neuro-immune-metabolic disorders such as depr...

Quantifying the Effects of Aerosol Size Distribution on Variations in Single Scattering Albedo

Abstract Aerosol optical properties, closely linked to complex physicochemical processes, critically influence climate and environmental impacts. However, quantitative links between particle size and the changing of scattering and absorption remain insufficiently constrained. Usi...

Younger Dryas Glacial Advances on the Tibetan Plateau

The Younger Dryas (YD) terminated the last glaciation and initiated the Holocene, which was accompanied by widespread glacial advances. Traditional scaling models, production rates, and outlier screening approaches for 10Be exposure dating often yield inconsistent formation ages...

Quasinormal modes of a charged spherically symmetric black hole in bumblebee gravity

Abstract Lorentz symmetry may be violated at the Planck scale. In the bumblebee model, a vector field acquires a nonzero vacuum expectation value, spontaneously breaking Lorentz symmetry. We study quasinormal modes of a charged spherically symmetric black hole in this framework,...

Attapulgite Nanocomposites for Cartilage and Osteochondral Repair: Material–Tissue Matching, Evidence-Graded Mechanisms and Translation

Attapulgite (ATP; palygorskite) is a fibrous magnesium aluminum silicate that can reinforce hydrated polymer networks, provide a surface for molecular interactions, and participate in formulation-dependent ion or drug delivery. Although ATP has been studied most extensively in bo...

A Lithium-Ion Battery Remaining Useful Life Prediction Framework Based on Mode Decomposition and CNN-TimeXer

Remaining useful life (RUL) prediction is essential for lithium-ion battery health management, yet accurate prognosis remains difficult because battery degradation trajectories are strongly non-stationary and often contain mixed-scale fluctuations together with local regeneration...

Tribenzotriquinacene Fused Dimers (“Fusodimers”)—Synthesis and Host–Guest Properties

ABSTRACT The synthesis and structural properties of two stereoisomeric tribenzotriquinacene (TBTQ) derivatives, syn ‐ 4 and anti ‐ 4 , in which two rigid TBTQ bowls share a common benzene ring, are described. Owing to the orthogonal orientation of the three indane wings in each o...

How digital leadership fosters employee proactive behavior: A dual-pathway model based on job demands and resources

BackgroundDigital leadership is increasingly recognized as critical to organizational digital transformation. How digital leadership fosters employee proactive behavior through job characteristics remains insufficiently understood.ObjectiveDrawing on Job Demands-Resources theory,...

Design and Synthesisof Potential Quinoline-BasedSDH Inhibitors Inspired by Quinine Alkaloids with Activity againstPhytopathogenic Fungi and Bacteria

Abstract In pursuit of environmentally friendly agrochemicals, we employed the natural quinine alkaloid scaffold as a lead for the design and synthesis of three series of structurally diverse quinine derivatives and systematically evaluated their in vitro antibacterial and antifu...

Mindfulness as a moderator of the association between physical activity enjoyment and academic burnout through self-control in Chinese primary school students

This study aims to examine the association between physical activity enjoyment and academic burnout, testing the mediating role of self-control and the moderating effect of mindfulness in the mediation model. Participants were drawn from twelve primary schools in China using conv...

From overweight/obesity to metabolic syndrome: increased postoperative survival risk in gastric cancer

Overweight/obesity and metabolic syndrome (MetS) are recognized as potential risk factors for gastric cancer, but their impacts on postoperative morbidity and overall survival (OS) following radical gastrectomy remain controversial. We hypothesized that overweight/obesity and Met...

Calibration of theMass Spectrometer of China’sChang’E-7 Lunar Soil Water Molecule Analyzer

Abstract The existence of water ice at the lunar south pole has become a major topic in contemporary deep-space exploration. China’s Chang’e-7 lunar mission is scheduled for launch in 2026. One of its primary scientific objectives is to conduct an in situ investigation of water i...

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

ABSTRACT The gravimetric and volumetric energy densities of 500 Wh kg –1 and 1000 Wh L –1 are considered as the “holy grail” target values for the development of all‐solid‐state lithium pouch batteries. However, the substantial amount of non‐energy‐providing deformable catholytes...
