Superdense wood is lightweight and strong as steel, and could be used to build bridges and cars

A new wood-compacting process crushes the gaps between cell walls in natural wood (porous structure seen in the scanning electron microscopy image, left), making the densified wood (right) as strong as steel. Newly fabricated superstrong lumber gives a whole new meaning to “hardwood.” This ultracompact wood, described in the Feb. 8 Nature, is created byContinue reading “Superdense wood is lightweight and strong as steel, and could be used to build bridges and cars”
