Improving the Circular Economy in the Iberian Pyrite Belt: Upcycling Mining Legacy Materials into Sustainable Cement-Based Composites

The mining sector is in urgent need of circular economy strategies to manage its historical environmental liabilities. This study investigates the upcycling of mining legacy materials from the Iberian Pyrite Belt (IPB) as sustainable substitutes for natural fine aggregates in cem...

Mapping the Strength–Ductility Landscape of Recycled Polypropylene Blends Through Automated Compounding

ABSTRACT The increasing use of recycled polypropylene (rPP) in engineering applications is limited by reduced ductility and material variability. In this study, a systematic experimental and statistical analysis approach was used to investigate polypropylene (PP) blends combining...

Hydrothermal origin of metabolic phosphorylation

Abstract Phosphate is central to modern bioenergetics and to all theories for the origin of life. How phosphate entered metabolism is unknown, though microbial physiology and geochemical environments can provide important clues. Some bacteria obtain electrons and energy from phos...

Deformable precipitates locally modify fault-mediated plasticity for strength-ductility synergy

Precipitates in structural alloys are conventionally understood as passive obstacles to dislocation motion. Here we show that semi-coherent hexagonal close-packed precipitates in a low-stacking-fault-energy Ni50Co30Ru20 multi-principal element alloy cooperate with planar-fault pl...

Integrating multimodal dot product fusion with conditional generative adversarial network to build a C-P-S-P chain in Mg alloys

Establishing quantitative relationships among composition, process, structure, and property (C-P-S-P) is a fundamental challenge in materials science, yet conventional models relying solely on numerical data fail to capture microstructural spatial heterogeneity, limiting predicti...

Modulating Local Coordination in Single‐Atom Catalysts: From Fundamental Concepts to Emerging Breakthroughs in Electrocatalysis

ABSTRACT Single‐atom catalysts (SACs) have attracted significant interest due to their maximized atom efficiency, structural precision, and unique catalytic properties. While the central metal atom in SACs serves as the primary active site, its catalytic behavior is strongly infl...
