Fe3+-Substituted Sr6YAl(BO3)6 Red Pigments Designed Without Pb, Cd, or Hg: Colour Performance, Chemical Stability, and Elemental Release Screening

Red inorganic pigments traditionally rely on Pb-, Cd-, Hg-, or Cr(VI)-based colourants that carry avoidable hazard and exposure risks. Here, a family of Sr6YAl1−xFex(BO3)6 (0 ≤ x ≤ 1) pigments was prepared by solid-state reaction using Fe3+ as the chromophore and no Pb-, Cd-, Hg-...

Influence of the biomimetic textures inspired by Monstera deliciosa on the friction and wear of rolling bearings under starved lubrication

Purpose This study aims to evaluate the tribological performance of textured cylindrical roller thrust bearings under starved lubrication, with particular emphasis on the effects of various leaf-inspired textures, depths and their combinations. Design/methodology/approach Inspire...

Poly(propylene carbonate- co -thioether- co -ether) Terpolymer and Its Application as a Solid-State Electrolyte

Abstract Sulfur-containing polymers, especially those with sulfur in the main chain, have attracted significant interest owing to their diverse structures and unique properties, making them promising candidates for solid-state electrolytes. However, their controllable synthesis i...

SpectralMol: Spectral Graph Bisection Achieves Universal Molecular Fragment Decomposition for Drug-Like Molecule Generation

Abstract Generating valid, diverse, and drug-like molecules remains a central challenge in computational drug discovery. A key bottleneck for fragment-based generative models is decomposition coverage: existing junction-tree methods fail on bridged bicyclic and spiro ring systems...

Auditory–Olfactory Integration in Simulated Natural Environments Dissociates Neural and Subjective Responses in Visually Impaired Individuals

Visually impaired individuals rely on cross-modal plasticity to compensate for absent visual input, yet the neurophysiological mechanisms underlying naturalistic auditory–olfactory integration remain poorly characterized. This study investigated how combined auditory and olfactor...

CausalSTKT: Disentangled Spatiotemporal Heterogeneous Graph Learning for Robust Knowledge Tracing Under Distribution Shifts

Knowledge tracing supports adaptive intelligent tutoring systems by estimating learners’ evolving knowledge states from sequential interactions. However, existing models often rely on dataset-specific correlations and may suffer substantial performance degradation under distribut...

Crystal structure and photoluminescence properties of Ho3+-doped germanium garnet phosphor NaY2Ga2InGe2O12

Abstract Narrow-band green phosphors with tunable decay dynamics have attracted continuous interest for exploring novel luminescent materials. In this work, a series of Ho 3+ -doped sodium yttrium gallium indium germanium garnet (NYGIG) phosphors were synthesized via a convention...

pH-Responsive Mixed Polymeric Micelles as Gel-Related Nanocarriers for Drug Delivery: A DPD Study on Block Ratio Modulation

Polymeric micelles represent a fundamental self-assembled architecture of gel-based soft materials and have emerged as promising nanocarriers for anticancer drug delivery. Their performance is largely governed by the block composition of constituent copolymers, and understanding...

Multifunctional Hydrogel Based on Synergistic Hydrophobic and Multivalent Hydrogen-Bond Interactions

Abstract Developing soft materials that integrate high mechanical performance, self-healing, adhesion, and stimulus-responsive functions remains challenging due to the trade-off between dynamic reversibility and mechanical resilience. Here, we report a P(AA-MA-OA-FHMA) hydrogel f...

A G4P[13] Porcine Rotavirus a Strain with Genomic Features Suggestive of Reassortment: Isolation, Genomic Characterization, and Pathogenicity in Piglets

Porcine rotavirus A (PoRVA) is an important cause of diarrhea in neonatal piglets, resulting in significant economic losses in the swine industry. In this study, a PoRVA strain, designated QY, was isolated from diarrheic piglets and systematically characterized. The virus was pro...

Huai Chrysanthemum polysaccharides alleviate high-fat diet-induced obesity accompanied by gut microbiota remodeling and altered short-chain fatty acids metabolism

Obesity and its associated metabolic diseases have become a global public health issue. However, the long-term application of existing therapeutic drugs for obesity is limited due to their side effects. Huai Chrysanthemum is a medicinal and edible chrysanthemum cultivar from Jiao...

A Lightweight Grayscale-Guided Visual Perception Network for Jadeite Transparency Detection

Jadeite transparency grading is challenging because adjacent categories exhibit high visual similarity and commercial images often contain complex backgrounds and acquisition-related variations. This study proposes a lightweight grayscale-guided visual perception network based on...

Heavy Metal Pollution in River Sediments: Risk Assessment, Source Apportionment, and Remediation—A Review Focusing on Chinese River Basins

River sediments act not only as important sinks for heavy metal pollution in watersheds, but also as potential secondary sources under changing environmental conditions. Heavy metals can enter river systems through industrial wastewater discharge, agricultural non-point runoff, u...

Latent profiles of instrumental and relational generative AI engagement among university students

This study examines how university students engage with generative AI (GenAI) across instrumental and relational domains using two independent, domain-specific exploratory surveys of Chinese university students (Study 1: N = 517; Study 2: N = 508). Study 1 assessed instrumental i...

Structural resilience and functional recovery in college students’ mental-health network: a Bayesian network and simulation-based intervention study

Mental health concerns among college students have received growing attention in China, where routine psychological screening has become part of campus-based mental-health services. However, analyses of these data typically rely on total scores or isolated symptom elevations, pay...
