Enhancing the interfacial transition zone of coal gangue aggregate mortar through the synergistic effect of red mud substitution and CO₂ mineralization during mixing

To improve the weak interfacial transition zone (ITZ) associated with coal gangue (CG) aggregates while promoting industrial solid waste valorization and carbon reduction, a synergistic modification strategy combining red mud (RM) substitution (8–24%) and in-situ CO₂ mineralizati...

GaPt alloy in HZSM ‐5 for highly stable ethane dehydroaromatization

Abstract The dehydroaromatization of ethane to aromatics is a highly attractive yet challenging route for valorizing the second‐most abundant component of natural gas. Here, we report bimetallic xGa0.8Pt/HZSM‐5 catalysts that exhibit markedly enhanced stability and coke resistanc...

Spatiotemporal Patterns and Driving Factors of Water Self-Purification Capacity in the Source Area of the Western Route of the South-to-North Water Diversion

The water self-purification capacity in the source area of the Western Route of the South-to-North Water Diversion Project of China was investigated. This research aimed to promote the coordinated development of water source protection and water diversion benefits. Based on water...

Machine Learning‐Assisted Prediction and Analysis of Viscosity and Fusion Characteristics for Coal and Biomass Ash

ABSTRACT Coal and biomass are important solid fuels, and the viscosity and fusion temperature of their ash have a significant impact on the stable operation of entrained‐flow gasifiers with liquid slag discharge. In this study, separate machine learning (ML) models were developed...

Photo‐Enhanced Electronic Metal–Support Interaction Boosts Low‐Temperature Water–Gas Shift Reaction via Ni δ+ –O V –Ce 3+ Interfacial Redox Cycling

ABSTRACT Nickel (Ni) is an attractive non‐noble‐metal catalyst for the water‐gas shift reaction (WGSR), yet strong CO adsorption and competing methanation severely limit its activity and selectivity. Herein, we develop a series of NiCe layered double hydroxide‐derived catalysts (...

Low‐Temperature Sodium‐Ion Batteries: Interfacial and Bulk Perspectives on Performance Limitations and Improvement Strategies

ABSTRACT Sodium‐ion batteries (SIBs) are attractive for low‐temperature energy storage because of their low cost and abundant resources. However, their low‐temperature performance still suffers from capacity decay, severe polarization, poor cycle stability, and increased sodium‐p...

Numerical Study on the Tensile Strength and Failure Characteristics of Coal Mass with Pressure Relief Drilling

Abstract Pressure relief drilling is an effective measure for rockburst prevention and control. However, the tensile behaviors of the coal and rock mass with boreholes are prominently changed. Therefore, the significance of tensile loading condition on the mechanical properties o...

Shaking Table Test on Liquefaction of Sandy Soil Site and Sensitivity Analysis of Liquefaction Influencing Factors

Earthquake-induced soil liquefaction poses a severe threat to the structural safety of underground infrastructure. This paper presents a shaking table model test conducted on sand sites, where two site models—namely, uniform saturated sand and layered dry–saturated sand—are desig...

Rhizobia-mediated soybean rhizosphere and nodule endophytic microorganisms reduce bioavailability of Cd and Cu in soil

Low-level bioavailable cadmium (Cd) and copper (Cu) in agricultural soils poses a severe threat to soil health and food safety; however, the mechanisms by which indigenous Cu-Cd tolerant rhizobia modulate plant-microbe-soil interactions remain poorly understood. In this field tri...

CO‐Adsorption on MgO Revisited: Polarization‐Resolved Identification of Step Edges as the Dominant Defects on MgO(100) and MgO(110)
