Multimetal Doping and Heterostructure Engineering of RuO2 for Durable and Efficient Oxygen Evolution

Small Science, EarlyView.
A MnCoNi–RuO2 heterostructure engineered through multimetal doping and mixed‐oxide interface formation generates lattice distortion, oxygen vacancies, and electronically optimized active sites for the oxygen evolution reaction. MnCoNi–RuO2 achieves high activity and durability across alkaline and acidic media, sustaining 100 h (AEMWE) anion exchange ...

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

steel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

steel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

Fatigue Performance and Failure Loads of Composition‐Gradient Multilayer Zirconia: Partial‐Coverage Restorations Versus Single Crowns at Different Thicknesses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study investigated the influence of restoration type (partial‐coverage versus crown) and ceramic‐layer thickness on the fatigue behavior and failure load of monolithic composition‐gradient multilayer zirconia (4Y‐PSZ/5Y‐PSZ) molar restorations. Material and Methods Seventy‐two CAD/CAM‐fabricated monolithic zirconia restorations (
