Breaking the ORR Trade‐Off via Mg‐Steered Fe‐N4 Pyridinic Conversion

Small, EarlyView.
A Mg‐assisted sacrificial templating strategy is developed to selectively regulate the coordination environment of Fe–N4 sites. This approach induces an active site conversion from S1 to S2, enabling enhancement of oxygen reduction activity and durability. ABSTRACT Single‐atom Fe sites coordinated by pyrrolic nitrogen (Fe‐Npyrr‐C) are highly active for

Assessment of Soiling Dynamics and Cleaning Efficiency for Photovoltaic Modules Under Different Dust Environments

Solar RRL, EarlyView.
A laboratory framework reproduces site‐specific soiling and cleaning dynamics of photovoltaic modules using real dusts from contrasting climates. Accelerated humidity–temperature cycling replicates 1 month of outdoor cementation in only ≈ 1.5 days.

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

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 ...
