Mechanism and Application of Biochar as an Electron Shuttle in the Remediation of Soil Pollutants

Biochar has attracted increasing attention in soil remediation due to its porous structure, abundant surface functional groups, and environmental compatibility. Beyond its conventional roles as an adsorbent and soil amendment, biochar has increasingly been recognized as an electr...

Seeking Stability Amid Uncertainty: The Impact of Climate Policy Uncertainty on Corporate Innovation Resilience

As the global sustainability agenda and carbon neutrality goals continue to advance, climate policy has become an important governance instrument for promoting firms’ green and low-carbon transformation. Adjustments in policy timing, regulatory intensity, and enforcement arrangem...

Effects of Lanthanum Doping on Structural Evolution, Morphological Features, and Flux Pinning in FeSe0.5Te0.5 Single Crystals with Machine Learning Assistance

Abstract Single crystals of La x Fe 1− x Se 0.5 Te 0.5 ( x = 0, 0.02, 0.04, 0.06, 0.08) were grown using the self-flux method. A systematic investigation of the effects of La addition revealed changes in the lattice parameters, with the lattice parameter a decreasing and the latt...

Joint MLP and Token Pruning for Personalizing Vision Transformers

ViTs have achieved excellent performance in image recognition tasks, but their large parameter counts and high computational complexity limit their deployment on resource-constrained devices. Most existing ViT pruning methods adopt class-agnostic pruning strategies, which fail to...

Assessing Differentiated Land Supply Performance Under China’s Major Function-Oriented Zone Strategy: A Scale–Structure–Efficiency Perspective

China launched the major function-oriented zone planning (MFZP) strategy in 2010 to address regional imbalances and resource–environment pressures through differentiated regulation. Using county-level data from 2010 to 2020, this study develops a “scale–structure–efficiency” fram...

Molecular-level insight into water adsorption and projected atmospheric water harvesting performance in a hydrolytically stable MOF

Sorption-based atmospheric water harvesting (AWH) promises a solution to the global challenge of water scarcity and, despite the increasing number of promising AWH materials, there remains a need for insight into pore-filling mechanisms and the hydrolytic stability of such desicc...

Preparation Method of Simulated Deep Sandstone Materials Based on Dual Equivalence of Principal Components and Mechanical Properties, and Quantitative Evaluation of Simulation Effectiveness

Intact deep sandstone cores are scarce, heterogeneous with poorly repeatable, limiting systematic laboratory studies of deep-rock mechanical behavior. This study selected dense sandstone recovered from 1050 m in the Pingdingshan mining area as the prototype system for the develop...

Climate Justice in Sports: Quantifying the Thermally-Induced Competitive Inequality

This study examines the impact of thermal stress on competitive inequality in professional football. Using a labor productivity framework and a dataset of over 39,000 matches from the Big Five European leagues (France, England, Germany, Spain, and Italy) spanning 1996 to 2019, we...

Research on the dynamic evolution of competitive and water-film-mediated wear mechanisms of the carbon strips in the pantograph-catenary system at low temperature

Abstract To investigate the evolution of wear mechanisms in carbon strips at low temperature, this study conducted comparative friction tests on copper-impregnated carbon strips at room temperature (25 °C) and low temperature (-20 °C). To replicate operating conditions, the exper...

Catalytic Regulation of Reaction Networks in High-Concentration 5-Hydroxylmethylfurfural Oxidation

Abstract The selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a key catalytic transformation for the production of renewable polymers. Although near-quantitative FDCA yields can be achieved under dilute conditions, increasing substrate...

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...

A Comparison Study on the Dynamic Response of Rectangular and Circular Pile–Slab Retaining Walls Against Rockfall Impact

Abstract Pile–slab retaining wall (PSRW), as an innovative passive protection structure for mitigating rockfalls, has been extensively utilized in the western mountainous regions of China. A typical PSRW is composed of reinforced concrete piles, concrete slabs, and a soil cushion...
