Combining H2O2-SupplyingIron Peroxide Nanoclusters with GSH-Depleting Gold Nanoclusters forEnhanced Chemodynamic Therapy via Amplification of Oxidative Stress

Abstract Chemodynamic therapy (CDT), which employs •OH generated by Fenton-type reactions to trigger cancer cell death, has received much attention in recent years. However, CDT efficacy is restricted by insufficient H2O2 levels and reactive oxygen species (ROS) consumption by an...

Hydrological Drought Modeling Under the Impact of Climate Change in the Luanhe River Basin: A Prediction Study

Against the backdrop of climate change and compounded by human activities, increasing water scarcity has triggered a series of drought disasters, which have already severely impacted both ecological environments and socioeconomic production. The SWAT model, recognized for its str...

Multi-Year Variation Characteristics and Driving Forces of Groundwater Levels in the Yibin Area, Southern Sichuan, China

To support groundwater protection and sustainable utilization in southern Sichuan, this study aims to clarify the multi-year variation characteristics of groundwater levels (GWLs) and identify their main driving factors in the Yibin region. In this paper, 2019–2024 GWL monitoring...

Automated Extraction of Long-Term Cyanobacteria Blooming Series from Landsat Imagery Using Deep Learning

Cyanobacterial harmful algal blooms (CyanoHABs) pose serious threats to inland water ecology and environmental security. Despite advances, accurately capturing their long-term dynamics for effective governance remains challenging due to limited datasets and segmentation model acc...

Mechanism of lateral resistance in obliquely inclined bedding rockslides: a case study of the Shanyang rockslide

Obliquely inclined bedding rockslides are prone to severe casualties and great economic loss for its less visible apparent dip slide. The lateral resistance is key to understanding the failure mechanism of obliquely inclined bedding rockslides. Nevertheless, few studies have cond...

Strength enhancement and microstructural evolutions of dredged slurry stabilized with waste-modified composite binder

Dredged slurry with high water content and low permeability is prone to drainage clogging during vacuum preloading, limiting its direct use in land reclamation and typically requiring cement-based treatment. To explore a lower-carbon alternative to conventional treatment, this st...

Path-Dependent Diagenesis and Facies-Controlled Reservoir Quality in Lower Cretaceous Fan-Delta Sandstones, North Yellow Sea Basin: A Model for Superimposed Rift Basins

The Lower Cretaceous fan-delta sandstones in the North Yellow Sea Basin underwent a distinctive polyphase burial trajectory, offering a natural laboratory to investigate path-dependent diagenesis and its impact on reservoir quality evolution in superimposed rift basins. Integrati...

Flocculation and Dewatering Mechanisms of Pyrite Flotation Tailings: Synergistic Roles of Polyferric Chloride, Polydiallyldimethylammonium Chloride, and Skeleton Builders on Microstructure Evolution

This study investigates the conditioning and deep dewatering of pyrite tailings slurry using a composite system comprising polyferric chloride (PFC), polydiallyldimethylammonium chloride (PDMDAAC), and fly ash as a skeleton builder. The synergistic application significantly enhan...

Early Jurassic Granitoids in the Pairigang Area, Tibet: Implications for the Evolution of the Neo-Tethyan Ocean and the Accretion of Juvenile Crust in the Southeastern Lhasa Block

The Jurassic represents one of the most significant periods within the widespread Mesozoic magmatism of the Lhasa Block; however, its formation age and petrogenesis have led to controversy over the deep genetic mechanisms responsible for magmatism. To address this, we present new...

Integrating Land Use Change and Vegetation Resilience to Assess Ecological Impacts of Expressway Construction: A Case Study of the Linghua Expressway

The rapid expansion of road construction has significantly contributed to economic development and regional connectivity. However, linear infrastructure such as roads, railways, and utility corridors has also introduced considerable ecological disruptions. Although increasing glo...
