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...

Negative‐Thermal‐Expansion Strategy Enables Hard Carbon With Tuned Heat/Strain Tolerances for Sodium Storage

ABSTRACT The thermal/stress runaways pose a risk to the safety and industrialization of sodium‐ion battery (SIB), which hence requires external management equipment. Actually, the thermal/stress generation originates from the repetitive Na + intercalation within carbon interlayer...

Phase-Dependent Reprogramming of Co–O Bonds in Fe-Doped Cobalt Molybdate for Durable Oxygen Evolution Reaction

Abstract Dynamic reconstruction enables active oxyhydroxide formation in alkaline oxygen evolution reaction pre-catalysts but often induces overoxidation and degradation when uncontrolled. Herein, Fe-doped cobalt molybdate microrod arrays (FCMO) are developed as a durable OER pre...

Coal-based hard carbon anodes for sodium-ion batteries: A review

Abstract Hard carbon is prioritized as the anodes candidate in sodium-ion batteries (SIBs) due to its excellent sodium storage performance. The precursors for hard carbon anodes are diverse, including biomass, organic macromolecule polymers, asphalt, and coal. Among these, coal i...

A Thermoelectric Hydrogel-Based Insole with Self-Decoupled Temperature and Pressure Sensing for Diabetic Plantar Monitoring

Abstract Plantar temperature and pressure reflect the plantar health status of diabetic patients and serve as critical indicators for evaluating disease progression. However, existing plantar monitoring devices are still limited by single-modal signal acquisition, bulky device co...

A study analyzing factors retarding digital transformation and configuration pathways: Based on the perspective of digital transformation acceptors

The high-touch service nature of the hospitality industry highlights that the success of digital transformation depends primarily on human factors rather than technology itself. Existing research indicates that approximately 80% of strategic initiatives fail due to employee resis...

Effect of N and Mo Contents on Precipitation Behavior, Intergranular Corrosion Resistance, and Mechanical Properties of Super Austenitic Stainless Steel

High‐Mo super austenitic stainless steels are prone to precipitate Cr‐ and Mo‐rich σ phases during hot working, which severely impairs their corrosion resistance and mechanical properties. To regulate precipitation, maintain corrosion resistance, and enhance strength, the key lie...

Disturbance-responsive online lithium-ion battery SOH estimation and analytical knee-point tracking with a Dual-Weibull Physics-Inspired Model

Accurate online estimation of lithium-ion battery state of health (SOH) and knee points remains challenging because feature-based estimators can be sensitive to changes in input-data quality, whereas conventional empirical models may lack the flexibility. Therefore, this study pr...

Tuning donor–acceptor interactions via electronic modulation in Ga-doped ZnO for carbon chain growth from syngas

Higher alcohol synthesis from syngas over conventional CuZn catalysts often encounters a trade-off between total alcohol selectivity and C 2 + distribution. Here, we show that Ga-doped ZnO enables precise electronic modulation to balance donor and acceptor reactions through contr...

Boosting ambient-pressure CO2 hydrogenation to methanol: Lattice Mo doping modulates electronic structure of In2O3

Precisely modulating the local electronic structure of oxygen vacancies is key to improving the inferior catalytic activity of In 2 O 3 toward CO 2 hydrogenation to methanol under atmospheric pressure. Herein, we demonstrate that lattice-incorporated Mo, rather than surface modif...

Failure‐Guided Coupling of Interphase and Solvation Chemistry for Durable Aqueous Zn–S Batteries

ABSTRACT Aqueous Zn–S batteries offer high theoretical energy density and intrinsic safety, but iodine‐mediated sulfur conversion introduces severe chemical and electrochemical instability at Zn anode. Herein, life‐cycle‐resolved three‐electrode measurements reveal that, although...

Correlation between Ni Valence States Regulated by High-Electronegativity Chalcogens and Acidic CO2 Electroreduction to CO

Abstract Ni-based catalysts serve as an alternative to noble metal CO2 reduction reaction (CO2RR) catalysts. However, the excessive adsorption of *CO leads to a poisoning effect and hinders its desorption for the production of CO. Herein, we describe the systemic regulation of Ni...
