High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

Polymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

AI‐Revealed Transition From Density‐ to Connectivity‐Controlled Mechanics in Hierarchical Porous Materials

Small, EarlyView.
Using synchrotron‐based multiscale imaging, generative modeling algorithms, and computational mechanics models, our study reveals a scale‐dependent transition in bone mechanics. The results of the power‐scaling law illustrate a transition from density‐controlled stiffness at the trabecular scale to connectivity‐controlled, porosity‐sensitive mechanics ...

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
