Assessment of Terrestrial Carbon Sinks: A Review of Methodological and Framework Limitations and Future Prospects

Ecosystem carbon sinks are a key indicator of terrestrial ecosystems' ability to absorb and store atmospheric CO₂. Their accurate assessment is of great significance for addressing global climate change and achieving carbon reduction targets. Due to limitations in the timeliness...

MSSFFE-Net: a fine-grained object recognition network based on multi-scale spatial-frequency domain feature enhancement

The challenge of few-shot fine-grained image classification lies in the scarcity of labeled training samples, which hinders models from learning subtle discriminative patterns. Moreover, most existing methods rely heavily on spatial-domain convolutional operations while overlooki...

Freeze–Thaw Durability and Pb Leaching Control of Graphene-Assisted MICP-Stabilized Pb-Contaminated Loess: Coupled Hydro-Environmental and Geotechnical Performance

Freeze–thaw cycling can strongly disturb the pore-water environment, soil fabric, and contaminant mobility of heavy-metal-contaminated loess, thereby threatening the long-term effectiveness of stabilization treatments in seasonally frozen regions. This study investigated the coup...

Trade-Offs Among Arc Erosion Resistance, Wear Resistance, and Compressive Performance: Designing Cu-Nb-Gr Composites with a Semi-Continuous Gr-Rich Structure Coupled with an Nb-Rich Load-Bearing Structure

Developing Cu-based composites with excellent electrical and mechanical properties under multiphysics-coupled service conditions remains challenging. Novel Cu-Nb-Gr composites were fabricated by high-energy ball milling and High-pressure Multi-field Assisted Rapid Sintering. Expe...
