Tooth enamel is both hard and resistant to impact, which makes it an extremely durable material that lasts a lifetime. A team of researchers at the University of Michigan in the US have now succeeded in making the first faithful replica of this enamel, which not only matches its structure but also its properties. The new work could help in the design of damage-resistant alternatives to ceramic composites, which although stiff and hard, are also brittle………
