Scientists have successfully reinforced wood with nanocrystalline iron, creating a stronger, eco-friendly building material with minimal weight gain. The breakthrough process injects ferrihydrite minerals directly into wood cell walls, strengthening their internal structure while maintaining flexibility. This alternative to steel and concrete in buildings and bridges could significantly reduce carbon emissions.
