Experimental Study on the Dust Removal Performance of Wet Chord Grid Water Film for Fine Dust

Fine dust generated during mining operations has become a key factor restricting the sustainable development of mines. The wet chord grid water film (WCGWF) dust removal technology, based on its unique dust–water interaction mechanism, has shown superior performance in removing c...

Fractal Acoustic Emission Characteristics and Energy Evolution of High-Water-Resistance Concrete Backfill: Roles of Water-to-Cement Ratio and Fiber Volume Fraction

Fiber-reinforced high-water-resistance concrete backfill (FHWCB) is a rapid-setting cementitious backfill system used for underground support and backfilling, but its stability is strongly affected by mixture water content and fiber dispersion. This study investigated the fresh-s...

Caging Polyhalide Anions in Polycyclodextrin for Long‐Lasting Aqueous Zinc‐Iodine Batteries

ABSTRACT Confining polyiodide species at the cathode is pivotal to the stability and long life of aqueous zinc‐iodine batteries (AZIBs). Current approaches using porous inorganic materials to physically trap polyiodide species or organic additives to electrostatically bind them r...

Promoting Polysulfide Conversion via a Lithium-Ion Reservoir Based on La-Doped MoO3 Nanorods for Li-S Batteries

The practical application of Li-S batteries is seriously plagued by the severe shuttle effect and sluggish conversion kinetics of polysulfides. To circumvent these obstacles, we herein construct La-doped MoO3 nanorods (La-MoO3) as a functional lithium-ion reservoir for sulfur hos...

Fabrication of Dense Crosslinked Network in Polybenzoxazine Aerogels via Melamine for High Compressive Strength

ABSTRACT Polybenzoxazine (PBz) aerogels fabricated via a water–ethanol mixed green system are attractive for thermal insulation but are limited by inherent brittleness and the environmental burden of their conventional fabrication. To address this, we developed a high‐strength hy...

Peukert‐Informed Prediction and Screening of Manganese‐Based High‐Rate Potassium Cathode

ABSTRACT Manganese‐based layered oxides have emerged as promising cathode materials for potassium‐ion batteries owing to their low cost, environmental benignity, structural diversity, and high theoretical capacity, yet suffer from poor rate performance. Compositional regulation o...
