Small, EarlyView.Incorporation of p‐phenylenediamine (pPD) into the polymer–pPD supramolecular artificial SEI reduces the activation energy for Li‐ion desolvation at the interface and promotes Li‐ion transport through the layer, thereby ensuring uniform delivery of Li‐ion into the SCN and stable cycling performance regardless of the inherently uneven thickness of the ...

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

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
steel research international, EarlyView.Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Boreas, EarlyView.Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT This study investigates the impact of hydrogen soaking on the medium‐cycle fatigue behavior of various metallic materials commonly used in gas transmission pipelines. The tested materials include ex‐service gray cast iron, ex‐service X52 carbon steel, brass, and welded X52 carbon steel.
