Evolutionary Game Analysis and Capability Reconstruction of Coal Mine Disaster Emergency Governance Oriented Toward Collaborative Resilience

Coal mine disaster emergency governance requires sustained coordination among regulators, mining enterprises, and professional rescue forces. This study develops a budget-closed tripartite evolutionary game in which subsidy/support outflows and penalty-revenue incidence are repre...

Pore Space Partition in Indolo[3,2- b ]carbazole-based Zr-MOF via Post-Synthetic Linker Installation for Enhanced Ethane/Ethylene Separation

Abstract The separation of ethane (C2H6)/ethylene (C2H4) by metal–organic frameworks (MOFs) depends largely on the pore environment. Here we construct a C2H6-selective mesoporous Zr-MOF, NUT-77, using indolo[3,2-b]carbazole-based tetracarboxylate ligands, and then apply post-synt...

Synergistic Mechanisms of Bio-Based Polymers and Silica Nanoparticles in Foam-Based Biomass Dust Suppression: Experiments and MD Simulations

Abstract Dust explosions in biomass processing motivate the development of eco-friendly foam dust suppressants. This work formulates foams comprising zwitterionic surfactants, bio-based polymers (CMC, SA), and SiO2 nanoparticles and correlates macroscopic wetting, drainage, and d...

Climate Shocks and the Spatial Reconfiguration of Financial Risk: Evidence from China’s Urban Equity Network

Climate risk has become a major challenge for the development of sustainable finance and the enhancement of regional economic resilience. However, limited attention has been paid to how climate shock affects the spatial organization of financial dependence across cities. Using da...

Numerical Investigation of Competitive Methane Transport in Multiborehole Coal Seam Drainage and Its Implications for Borehole Layout Design

Abstract Methane drainage efficiency in coal seams is significantly affected by borehole arrangement, as overlapping pressure sinks in multiborehole systems can redistribute gas migration pathways and reduce the effective performance of individual boreholes. To quantify this inte...

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...

Quantification and Mechanism of the Interborehole Effect in Coal Seam Gas Drainage

Abstract Coal seam gas drainage is crucial for reducing carbon emissions and ensuring safe coal mine production. In engineering, multiborehole combined drainage is widely adopted. However, the interaction among boreholes leads to the complex superposition of their respective infl...

Weakening Local Chemical Bonds for Enhanced Thermoelectric Performance in YbMg 2 Sb 2 Zintl Compounds

ABSTRACT Alloying is a well‐established strategy for reducing lattice thermal conductivity ( κ L ) and enhancing thermoelectric performance of materials, typically explained by the Klemens model, which describes the point‐defect phonon scattering via mass and size contrasts. Yet,...

Influence of Electrode Surface State on Air Gap Breakdown Characteristics at the Micrometer Scale

To investigate the influence of electrode surface roughness on gas discharge characteristics under micro-gap conditions, direct-current breakdown experiments were carried out in atmospheric air using a nano-positioning system. Breakdown tests were conducted for five metal electro...

Study on the Thermal Degradation Mechanism Model of Polystyrene Insulation Materials Under Ultraviolet Aging

ABSTRACT Expanded polystyrene (EPS) and extruded polystyrene (XPS) are extensively employed as thermal insulation materials in buildings. However, facade spalling exposes these materials to ultraviolet radiation, triggering progressive aging that compromises their thermal stabili...

Pressure-ControlledDynamic Conversion of Replacement–DisplacementMechanisms During ECBM Recovery

Abstract Gas injection pressure is a key parameter controlling enhanced coalbed methane (ECBM) recovery, as it directly influences gas adsorption–desorption, diffusion-seepage, and the dominance of replacement-displacement mechanisms. In this study, carbon dioxide (CO2) and nitro...

Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

ABSTRACT In the field of mining, conventional methods that rely on protective coal pillars result in significant wastage of coal resources. To achieve the dual objectives of resource recovery and roadway stability control, this study utilizes theoretical analysis, numerical simul...

Early Identification of Subtle Deformations in Potential Debris Flow Source Areas Using Phase-Unwrapped Convolutional Neural Networks and Long-Time-Series InSAR Technology

Mudslides are sudden and highly destructive; their source areas typically undergo slow, millimeter-scale creep over a period of months or even years before destabilization. If these precursor signals can be detected, valuable time can be gained for disaster prevention and mitigat...
