Knots smaller than human hair make materials unusually tough

In the latest advance in nano- and micro-architected materials, engineers have developed a new material made from numerous interconnected microscale knots. The knots make the material far tougher than identically structured but unknotted materials: they absorb more energy and are able to deform more while still being able to return to their original shape undamaged.
